You are the ONLY person who has taken an unfathomable quagmire of poorly documented processes and organized the many many process steps and presented it so I can follow along. Thanks!!
@@dynevor6327 I didn’t. Video was perfect.
Freaking lifesafer! Thanks. Ingnore detractors who don't have a video.
I saw your video and it was the best explanation. Especially the heading in AS3X mode numbers. You made the explanation so absolutely clear for me!!
Congratulations on the success.

Thank you sooooo much, Spektrum should be ashamed of their lack of instructions!!!!!
Excellent video. Watched many before this and none made sense. Well done and thank you
Please disregard any MORON that critiques your video making skills or "organization". They are folks who have never tried to make anything happen themselves and always wonder why more things aren't done for their benefit. You never professed to be a camera expert, you're simply trying to help. The rest of us really appreciate that you took the time to actually go through and demonstrate what Spektrum seems to be unwilling to do (or, in their multimillion dollar attempt, failed miserably). This was much more informative than any Spektrum/Horizon Hobby video I've ever seen and I fly large scale and jets exclusively but friends are constantly asking me how to do this. Since I don't use SAFE or AS3X, I never know how. Now I have somewhere to send them and I now feel like I could help them myself. Many thanks for taking the time and effort.
Thanks for the kind words. I doesn't bother me. I really post these videos for me so I can go back and remember how I did something. If anyone else finds them useful then that's a bonus. 😉👍
Nicely said and true
I’m new to RC planes and after 3-4 weeks of watching different videos, I still didn’t understand forward programming. That is, until I watched your video. Many thanks!
when all else failed your video has shined and saved me once again major shout out and thanks for everything
You saved me! Best AS3X SAFE video how to ever!!! Now I get it. You filled in ALL the gaps that others forgot to mention. I'm bookmarking this one.
Glad you found it useful. Happy flying and keep one finger in that SAFE switch. Every time I try something with my jets I usually have to use it.
Thank you for your comprehensive tutorial! Sketrum likes to tease us with less-than-complete instructions for setups. Tried to unlock the T series to program and finally purchased a non-BNF R/X to succeed. Thanks.
Awesome video this allowed me to program my DX6e with an AR631 receiver. Thank you..
Thanks brother for loading step by step ….I setup mine watching your video
Alright that was excellent. All my years of flying that is the only thing i never bothered doing bc i let my friend do the programming but he is no longer available. So this is a excellent video and will help me alot. Thanks bud!!
Thanks for such a great informative video. I've watched several videos on setting up AS3X and SAFE&AS3X and nobody has explained in detail all the roll, pitch and yaw percentage settings which leads me to believe that I might not have been setup properly this entire time!
Yes I agree think I been havin the same problem
HEADING - wow I would never have found that, it worked a treat, thanks.
A really great tutorial. Answered lots of questions. Thanks
Best video I have ever seen for setting up a receiver. I setup all my receivers from this video. Thanks for going in depth with the process.
Most comprehendable video on this topic I've found yet. Not Overdone. Not underdone.
Best explanation of AS3X and SAFE I've ever heard. I've tried AS3X and SAFE on an AR637T than ended in a cluster F. I'm in the process of installing the receiver in a new airplane and I'll follow what you describe. Horizon should send you some free airplanes. Thanks for sharing this.
Now for the first time I understand the forward programming function. Thanks for an excellent video.
Extremely helpful video to learn forward programming. I followed step by step and everything worked as advertised. Now to the field to test! Thanks so much!
Happy to help...have a good flight!
Perfect, I had everything set up, I thought, but it didn't work, Setting the Heading as recommended solved it. Thanks.
Thank you very much! No one every told me how to activate AS3X correctly (Heading). I have crashed 3 planes not knowing what was wrong. Greatly appreciate it!
Thank you for this. I had a crash in a Conscendo evolution (tip stall in final approach caused by sudden wind shift). After a small rebuild and what I thought was a fairly good check out before launch (yes - servo directions were all correct), it climbed immediately on launch, looped over (despite full down elevator) and crashed. Another re-build and check of all flight surfaces produced the exact same result but landed in a tree. It pretty well survived and i checked and still all surfaces appeared to work correctly but believing it was cursed I hung it up in the garage.
Then a friend with the same model had a bad crash and when he reassembled it he inadvertently swapped the elevator and rudder servos. To get it to fly he had to reverse the direction of both servos. A very experienced pilot then offered to test fly it and it had the exact same crash profile as mine, climbing in ever increasing angles till it looped over and hit a tree. I had watched this carefully and realised it was though he had positive feedback on the elevator control loop and once climbing the error correction was reversed causing it to climb harder.
Sure enough, this turned out to be the case when we checked the operation in SAFE mode. The fact that he had mechanically reversed the servos (and corrected it on the transmitter did nothing to help the gyro know that things had been reversed!
Using this information I went and checked mine. I had not reversed the servos but still the gyro was controlling everything in reverse! I then reloaded the AR637 with the official flight software for the CONSCENDO but it still did not fix the problem. Finally I jailbroke the receiver and used your video guide above to dial in my own settings. It now flies flawlessly, though I am at a total loss to explain why this weird fault has appeared in my receiver.
I found your instructions easier to follow than those on the official Spektrum site. Thank you
Yes all the servos must be configured especially reversing before programming and the other is to ensure the plane is level when powering up plane when flying. Other than this with the basic programming it works well. Also I check that SAFE is working properly and the control surfaces are moving in the correct direction before flying.
I had previously used an AR 637T receiver for AS3X mainly but decided to try the cheaper version the AR 630 but was never able to make it work. After watching this video and going step by step slowly with lots of pauses and repeats I finally was able to get it to work. Good job on the video.
If you were not able to get the AS3X to work on the AR630 it might have been that the Heading was not set up. I'm not sure why it requires this setting but that's the only way I could get it to work. Thanks!
I’m with you,”lots of pauses and repeats”, but that’s because I’m old. I’ve never flown with gyro in the 37 years of crashing planes until Draco came out, so programming AS3X and SAFE has always been problematic for me until last night with Zek’s help and again, “lots of pauses and repeats.” Thank you Zek for all the time it must’ve taken you to get to the final edit for “ALL” who takes the time to watch and apply this wonderful video. Such an answer to prayers for me.
Thank you for the video. i just followed your directions and put a Visionaire up in the air after watching the spectrun videos for 2 months . watched your video 2 times and played it again as i set up an ar637t 40 min. layer i was flying. i cant stand dealing with Horizon Hobbies their customer support sux. thats sad when i have messed with rc stuff for 40 years. technology has come along way it feels good to put a plane in the air with confidence it will land safely, and not a total rebuild to try again
Just did my first forward programming and setup on an AR8360T and NX8 following your guidelines and it went prefect. Thanks for the video.
Thanks for this. I’d been struggling to work through some papers on how to jailbreak and program an AR631 that I had left over from an Aeroscout that suffered from a gravitational defect. This video made that soooooo much easier.
THANK YOU so much! As others have stated, yours is the ONLY tutorial that is easy to follow; enough but not too much info; and worked perfectly first time.
Beautifully done. GREAT work! 😎👍🏼
Ok, the results are in on my Graupner Partenavia upgrade ( from original 1990s technology: (7 cell nicad, Speed 400 brushed "can" motors, Futaba Attack-4 AM 72.550 MHZ transmitter , MCR 4A receiver speed control (with internal ESC))
Maiden flight using Safe and AS3X was picture perfect...all thanks to your tutelage with your very complete and logical video. The total wing loading is approx 30% less than the original design! It floats and descends like a B-52.. that is, horizontal controlled sink. it takes off in 10 feet. The nose wheel is fixed but rotation happens so fast that no steering is necessary. 10 minute flights on 3200 mAh 3cell 30C. Vertical as well! loving it! Thanks!
5/14/2023 update: I am all set to add flaperon function. Ailerons were not part of the Graupner kit so I added them way back in the late '90s. Can'wait to add flaperons.
Thank you, Thank you Zek1701. You made sense of this AR630. Hope others can find it. Spektrum should take notice, I will buy a few more for some planes that are getting ready to come out of the hanger. Thanks again for your time.🌟🌟🌟🌟🌟🌟
You’re welcome…glad you found it useful. Yes, I use their receivers on every jet. They allow me to try new things on the jets and know I can bailout by flipping a switch to get the jet level with SAFE.
Thanks so much , really appreciate you showing us how to get it working well
Excellent video, clearly explains the complexity of setting up as3x. Many thanks for taking the time to do this.
This video is god tier 👌🏻 Explained much better than some other bigger channels. Thank you!
Thanks for this. I’ve been looking into adding an AR630 to a small EDF jet that I recently crashed and I think having this set up will help a lot.
I've been looking for a video to help me with this set up and this is the best one out there, Thank You
Great instruction! It really helped me to get it working properly!
Envelope is like training wheels on a bicycle. The gyro will keep your plane from banking, climbing, or diving too steeply, but it won’t self-level. You’ll have to level it yourself. It’s an intermediate mode that will keep your plane from getting upside down and teach you how to level it yourself.
It's a handy setting for a test flight, you know the plane won't roll over on its back when selected.
Great video! Well done, very informative and clear instructions!
Thanks for this video. Its good info. I like that you took it slow.
Thanks. You solved a big problem for me. 👍
Thank's zek Makes first time setup painless 11/10 mate.
Very well demonstrated. Thank you so much.
I've found out that you don't really have to set heading for AS3X to work. The reason AS3X doesn't work is because by default the gains are set to adjustable and if you don't set a gain channel the gains will be set to zero ! If you change the gains to fixed then it works.
Arturo..awesome! I never understood setting heading made it work. I'll trying changing the gains to fixed.
Finally I fully understood a little better about setting up SAFE!
Clear instructions, straight forward instructions. Thanks for making this how to video😀
Ok! Eureka! I finally got both flaperons to function in Safe As3x!
I just did a factory reset then, with the flaperons set up in the Tx, I re'did it all over.
Safe DOES recognize the port 6 Aileron/flaperon afterall!
Got this working first on my Great Planes Trainer 60 so I decided to re-do my Stinson.
yes before fwd programming one needs to set up the aircraft control surfaces first.
@@Zek1701 yes, thank you. I use your video carefully step by step each time I set up a new plane... or add Flaperons. My Great Planes Trainer 60 has full span ailerons with flaperons function and really benefits from them.
Really great video on this. Thank you!
i setup every plane watching your video on all my jets...mig21,rafeal,baehawk,f4,su47,inttroder,f18
Yep me too.. Have you flown the SU-47?
Well done, Zek1701 - very informative - helped me resolve the problems I was having setting up AS3X on my new Spektrum receiver...
Yes probably had the no AS3X issue. Took a while to figure out how to make it work. Still don’t why.
The FW and AT F14s are on deck, ready to launch as soon as the EFlite F14 gets here(hopefully next month). Gonna fly all 3 the same day and make combo video. Should be fun.
@@Zek1701 I give you a lot of credit for figuring out how to properly set-up AS3X and SAFE - it's not always intuitive, especially setting the Heading - how'd you ever figure that out? Best wishes for successful day of flying the Cats - all three of them...
@@user-MichaelSBruno When I first started with eFlite jets(f15, F16) I got the programming cable and was able to see the configurations in the Spektrum receivers that were in the jets. Then when started to Fwd Programming the AR630s I didn't know what values to use so I just use what the F15/16 had. Also, when I programmed a number of these AR630s the AS3X would work on some but not others(frustrating). Then I realized that after setting up SAFE I need to go back into the Gryo setting and set the heading like the F15/16 had. Then AS3X would work. Don't know why though.
@@Zek1701 Good idea - well done...
Super presentaties, well done !
Interesting video. Thank you for producing. I subbed.
Great video ,think this may help me get my set up right ,did set it up on a ar637t but had hardly any aileron input and barely got it turned around back to me ,think I am going to do a reset and follow you method thanks so much for helping a newbie it 👍🏻
I been looking for this fix on the AS3X since I got into flying last year. Thanks!
Glad to help..took me a while to figure and now I setup all my jets this. I’m learning to fly inverted and flipping to SAFE prevented at least 5 crashes.
@@Zek1701 inverted? I am definitely not there yet. If only I could fly half as well as I do in FS 9...
Very very nice video - thank you!!
Great video !
Very nice video.
Excellent Video.. Thank you
Great video, thank you so much
bravo this has been very helpfull
Thank you helped me out thanks man
Thanks again. I have one question. I couldn't quite grasp how you set it up when you have flaps or a gear. When I switched from off to AS3X and SAFE the flaps come down. I tried changing the Flaps to the D switch and it worked fine but when I tested the AS3X nothing happened although the SAFE did. Please help if you can.
"I tested the AS3X nothing happened although the SAFE did." It sounds like you set everything up correctly. Recall you have to run the throttle to >20% to activate AS3X.
I never knew the bind channel can be used as a 7 channel thanks for the tip
I'm book making this video for future reference. 😊👍
Many thanks!!!
Greetings from Guatemala!!
I have been programming all my AR637T following your video.
On my last one (a seaplane), I had to set the channel on the FM Setup to channel 5 (Gear) because setting it up to channel 7 did not show the 3 Flight Modes but only Flight Mode 2.
Even toggling the switch it would not show the other 2 modes. Selecting Channel 5 fixed the problem.
I wonder why…
Again many thanks for a great tutoring video on Forward Programming on the AR637T.
Carlos
I would check that channel 7 is assigned to the switch you are toggling. Next, you should be able to see on the transmitter that when you toggle the channel 7 switch that the value change from 100,0,-100. That's how it works on a Spectrum transmitter.
Im not an expert. But i didnt need to set a heading. Instead go to capture gyro gains. It will set them to zero. Then go back to as3x gains and set the values you want. That worked for me without needing to add a heading. Great video and explanations, i was blocked and couldn’t get it to work . I looked at my setting on my f16 and it didnt have heading values so there had to be something else.
Thank you!
Is there a way to reset the ar361 or similar rx without forward programming or using the transmitter. Maybe through put the binding plug in Chanel 3 and 5 like in lemon receivers.
I am installing the AR630 in a 1/7 scale Globe Swift designed by Dennis Sumner. I intend to use SAFE mode for the maiden flight and likely subsequent flights. Do to the nature if the wing I fear it may snap roll. Your video is an excellent tutorial on how to program the AR630 but I have no experience with the setting you recommend for SAFE mode where you change Roll Right to 75%, Roll Left to 75%, Pitch Down 50%, Pitch Up 75%. Are these recommendations more for a jet? Or would they apply to a civilian aircraft like the Globe Swift or for that matter any RC model? Any insights would be appreciated.
No the roll rate would apply to any aircraft. Basically, it is how much of an arc the aircraft makes when turning. The normal set up takes a while to turn even when you have the stick all the way over. With these rates you can create more of a bank to turn quicker. These rates are just limits. SAFE will not let you roll or loop the aircraft. You can always put some expo in the roll if you are worried about a snap roll. Just be careful not to get too dependent on SAFE. SAFE also reduces your stick input by a percentage and when you switch to AS3X it get the full stick input. What I do it setup a switch where I can switch between SAFE and AS3X. When I first started flying I flew in SAFE but tried to ween myself off it. So when I flew in AS3X I knew if I got into trouble I could flip SAFE on and it would level the aircraft. Before flying make sure when you power on the receiver the aircraft is level. Happy flying!
Can you explain the Heading numbers for AS3X. How does this affect the airplane the higher you make the number, or the lower you make the number. Completely new at this. THANKS.
I think the throttle to pitch would work great on a foam aircraft I have that the faster it goes it begins to climb and I always have to add down elevator. My theory is the wings are bow some at high speeds causing more lift. I would like to have some down elevator added as throttle is applied, it may help this aircraft fly better.
Thanks for your video. It's helping me a lot.
I hated that throttle-to-pitch mix because on my first trainer plane they had that in the receiver. As I beginner I would takeoff at max speed then it was all I could do to get the plane to turn 180 degrees. By the time I finished the turn the plane was so I high I was starting to lose orientation. To this day I still don't like the idea. If you want to go up pull back on the stick...period!
Hello, great videos! I have a question: Can I easily set up the DX6 transmitter with the AR630 receiver without using a PC, as shown in your video, in order to activate the gyro ? Thx:)
I don't have a DX6 but from the Spektrum site a DX6e can do fwd programming. (www.spektrumrc.com/Content/Media/PDF/49890-dot-8-air-tx-chart.pdf). I have not tried to program AR630 with a PC - only the older receivers like the AR636B.
I have a Dx6e and an AR630. Have followed all directions but the "Forward Programming" option does not exist. Any ideas what could cause this? Everything is powered on. Everything is bound properly. I can control the plane, so clearly its bound. This thing is driving me crazy. Thanks.
I don't have a DX6e but I believe it should be capable of Fwd Programming. Maybe update the DX6i software and try it.
Great tutorial. I am a beginner and i want to have low an high rates, but you did not mentioned in the video. Can you please clarify if the are already in the SAFE modes? Am i missing something? Thanks
Low/High rates are independent from AS3X/SAFE. They are setup only on the transmitter and is not part of Fwd programming. In my case I have a DX9 and for a model I go into the D/R&Expo setting. Then I set the switch to F and I have 3 modes(High, Mid, Low). For High I set Dual Rate:100/100, Expo:0/0, Mid Dual Rate: 100/100, Expo: 40/40, Low Dual Rate: 70/70, Expo: 20/20. I do this for Aileron and Elevator. Typically I just fly with Mid rates. But - this is up to you as to what setup you like.
I was checking the surface movements to see that the surfaces moved correctly when in safe and AS3X. What I noticed is that the rudder does not move? I can move the rudder with the rudder stick. I also ran the throttle up over 20% and still no action on the rudder? Any ideas about something I may have missed in forward programming?
I don't believe the Spektrum AS3X/SAFE receiver provide directional control. AS3X only stabilizes in roll/pitch - not yaw. Likewise, SAFE only levels the aircraft(roll/pitch). I don't check nor believe I've seen the rubber move as a result of the receiver. If it does I don't use it. My planes are usually upside down and headed toward the ground...yaw is the least of my worries... 😄
there brilliant
I just stumbled across your video I’ve been using forward programing for some time now. But where did you come up with the heading numbers for while In Safe or AS3X. 4&8 and 15&30? My Vulcan has a slight oscillation when heading into the wind if I have safe on but in AS3X it’s smooth. My gains are set to fixed. But both my headings I have set is 0 I didn’t know what they were there for and couldn’t find info on it.
The heading numbers came from an old F16 with AS3X. I couldn't get AS3X to work when I first started programming and i just tried those numbers and magically AS3X started working. Another poster explained why AS3X didn't work. I haven't tried this yet:
@arturocaballero7208

I've found out that you don't really have to set heading for AS3X to work. The reason AS3X doesn't work is because by default the gains are set to adjustable and if you don't set a gain channel the gains will be set to zero ! If you change the gains to fixed then it works.
@@Zek1701 yes he’s right they are set to adjustable by default. I have AS3X working they been working but just in this one EDF I have the sensitivity set to 1x gains set to fixed but only in safe mode I get a slight oscillation. If I take it out of safe it’s locked in like on rails it’s very strange
Confused by your very last note... Does this mean that I must lift the tail of my tail dragger as I at the same time try to plug in my battery? How is it that I don't have to do this with my BNF planes that came with SAFE? [For example, my Timber... turn it upside down to load the battery, put the battery cover back on and then turn the plane over on its wheels and wait for all the beeps.] Thanks.
"Confused by your very last note" - please elaborate on exactly what note was confusing.
I started programing the AR630 using your instructions but hit a snag almost from the get go. I have a 5 channel aircraft throttle, rudder, aileron, elevator, retracts. I'm using a DX6 upgrade to the latest 2.09 sw so I do see the forward programming mode. The gear channel is assigned to switch A. Which lowers and raises the retracts. I have a sixth channel which is AUX1. However the DX6 does no allow me to assign that channel to a switch only channel 5 will take a switch setting. I can assign the AUX1 channel to Gear and I changed the Gear channel to switch D which on a DX6 is a three position switch to accommodate the AR630 three modes but now the retracts are also activated. Any idea how to free AUX1 so that I can use it to control the AR630. I would think I should be able to assign the 6th channel to any switch I want independent of the gear channel. Thanks in advance for your help.
You should be able to go into System Setup/Channel Assign, hit NEXT. In RX Port Assignments - Set AUX1: Aux 1. Then go back to Channel Input Config and select switch D or what ever switch you want for Aux1.
Ok. This is strange. I follow ur exact video and had the same issue with as3x. It would not activate with out heading. But then I decided to play with this and learn it. I did the basic set up leaving all stock setting. And the as3x started working normally. No heading. I’m using a NX10 and the AR10360T.
I learned so much from your video, but my as3x mode didn’t work plus as for using channel 7 it doesn’t seem to work either so I end up using my gear channel
But still your video are the best
Thank you for this video. I have installed a Spektrum 631 in a MotionRC DragonFly. I’m stuck because the aileron pushrods are on the top of the wing. In Safe, the aileron correction is correct. The elevator correction is backward. I can turn the receiver around and make the elevator respond correctly but then the ailerons go the wrong way. Can this be remedied in forward programming. Thank you so much. Julian Wilson
I'm going to assume that when the aileron/elevator are reversed it's when the receiver is flying the plane in SAFE mode. If you are flying the plane then you can do the reverse servo to get the aileron/elevator moving the right direction. So when the receiver is flying in SAFE I don't believe in Fwd programming you can do a "servo reverse" on the receiver. The only thing I can suggest is make sure you have the aileron/elevator going in the right directions when you are moving the sticks by doing servo reverse on the transmitter. THEN, do the fwd programming and setup SAFE. You should do the factory reset first. I believe the receiver learns the servo settings from transmitter when you start the fwd programming process. If this doesn't work I'd suggest contacting Spektrum/HH for suggestions.
@@Zek1701 Thank you Zek. Yes the sticks move the surfaces correctly. The entire problem is due to the DragonFly plane putting the aileron linkage on top of the wing instead of the normal underneath.
@@TheBrowLineTrolley hmmm seems like the receiver would be smart enough to pick that up from the transmitter and then apply fwd programming. There are warnings that if you change anything on the servos the receiver needs to "Relearn Servo Settings".
If you set up a receiver with SAFE mode selected, but have to invert one of the outputs because the flight control surface its operating opposite of what it should, does SAFE understand this and will it give the correct output to counteract a wind gust or axis change? Or will it make the situation worse ?
No you must set the servo direction before setting up SAFE. If you need to change servo direction after setup the is a relearn servo setting in fwd programming However you should confirm the control surfaces move as expected.
I just did this setup with my ix14 and ar631. Everything worked except as3x only. I don't hear or see anything happening. Do you have any idea why not. Thanks in advance.
See video at 22:30. Two things - 1) you have get the throttle above 20% to enable AS3X and 2) you have to set the heading in the set up. See video.
One question though, when setting it up on a taildragger, how should the airplane orientation be - tailwheel on the ground or elevated so the fuse is level??
Hi Pieter...I don't have a taildragger but I set it up fuselage level. For AS3X and SAFE the receiver is making corrections to make the aircraft level(pitch & roll) in flight. So when we set the receiver up initially AND when we power on the receiver prior to flight the aircraft should be level. In fact you might find if you don't level the aircraft when powering on the aircraft before flight the receiver may not initialize because it thinks the aircraft is not level.
@@Zek1701 Thank you so much for your reply. I was thinking the same, but wanted to be sure about it. If you think about it, it makes sense. Kind regards from Namibia.
I would like to see a video for re-programming AR636B’s
ruclips.net/video/WfTXQofK1GU/видео.html
Channel 5 (Gear) should be switch A. Channel 6 (Flaps) should be on switch D. I use switch B for dual rates/expo and also assign channel 7 (Aux2) to it for the receiver’s flight modes. Switch B position 0 is low rates with AS3X, 1 is high rates with AS3X, and 2 is high rates with SAFE mode. I assign channel 8 (Aux3) to the bind switch for panic mode. When I’m experimenting with gyro settings, I’ll put channel 7 on switch C so that the gyro modes are independent of the rates/expo. Of course, if you only have 6 channels, you’ll have to use channel 5 and 6 for flight modes and panic.
Switch setting is personal preference. In my case the AS3X/SAFE was on the B switch when I first started learning so that's what I'm comfortable with. Likewise for the other switches. Great thing about the DX9 or most transmitters is you are free to do what you want. To each his own.
@@Zek1701 The engineers at Spektrum were smart and used logic. They designed it so that when you create a new model, switch A is assigned to channel 5 (Gear) and switch D is assigned to channel 6 (Flaps). Most people fly Mode 2 which is aileron and elevator on the righthand stick. Your left hand is throttle and rudder, so it has less workload in the air. It’s usually available to flip switches while the right hand is busy flying. The A switch, being a 2-position switch is ideal for the landing gear. You can take your left index finger and easily find it to pull the gear up. The longer D switch is also easy to find. B and C are a little harder, but you will soon get use to using them for rates or gyro. Throttle cut needs a 2-position switch so I put it on switch H. Since I don’t use the other switches on the right side, I won’t accidentally kill my engine in flight. I like the way Spektrum’s engineers think. Their transmitters are easier to set up than other brands and their AS3X/SAFE receivers work great. You just weren’t taught the right way.. ;-)
I put an AR630 in a Freewing F35 seems to oscillate at plus 60% throttle. I have to turn the knob down all the way. What value would you recommend?
I've never setup a jet with a gain knob. I've always used the default gains for AS3X and SAFE which usually work well at any speed. I think I've only had one jet that the wings rocked back and forth a little so I reduced the AS3X roll gain by 5. When you say "oscillate" is this in the roll with wings rocking or pitch with the jet going up and down?
@@Zek1701 wings rocking.
@@notoo7 I assume roll rocking was when in AS3X mode. With the Gain knob its hard to tell what the settings were when this rocking occurred. If it were me, I would disable the Gain knob and start with default AS3X settings(Roll:40, Pitch:50, Yaw:60). If the wings still rock in AS3X I would lower the Roll to 30 and see if this corrects the issue.
@@Zek1701 thanks, I appreciate that. Hopefully I can test it this weekend.
I rarely use adjustable gains. I set the AS3X gains to fixed values of 30, 40, and 50 percent for roll, pitch, and yaw respectively with a multiplier of X1. If I think the plane needs more gain, I will increase all 3 by 10%. Generally, you can use 10% more gain on pitch than roll and 10% more on yaw than pitch. The ailerons/wing will tend to oscillate before the tail feathers.
Shouldn’t the unused channels just be inhibited instead of multiple channels on the same switch? Just tried to maiden mine and it crashed
Hi, i been watching your videos and are very helpful for me that start using spektrum, had to change radio on my model because after many year started working erratically, i have a model that have dual aileron and dual elevator plus rudder and throttle total 6 channels, i have the AR637T receiver and you stated on this video that you can have a extra channel out of this receiver and i really will appreciate if you help me setting up this extra channelbecause i need it for ignition kill, if not i will have to buy a receiver with more channels
The Bind/Prog/SRXL2 port shows up as Ch7 in the Channel Assign menu option. In my case I set Ch7:B so I can use the B switch turn on/off OFF/AS3X/SAFE.
Just trying to set up Flight modes for my 4 channel Stinson Voyager ARF with AR631 receiver and Dx8 tranmitter. (1 no as3x or safe) (2 As3x ) and (3 Safe) on switch B
Some things I found out: when you set the model "level" on a tail dragger, you must lift the tail to make the fuselage level, which is the orientation during normal flight. Also, Question: when you set up everything, I think you have to re-bind the receiver so all the settings etc are registered. Could you please confirm this or not? Thanks
My problem on my first try with this set up the AS3X mode acted just like the Safe setting. So I am going back to Factory reset then try again.
No you do not have to rebind to register the settings. When you go through the Fwd programming it ask you to Apply and this registers the changes. AS3X will act like SAFE when testing because AS3X is trying to correct for roll and pitch , since your sticks are in neutral. If you turn on the receiver, select AS3X, rock the aircraft and you don't hear servos moving, then give 20% throttle, rock the aircraft and then hear the servos moving then AS3X is working. SAFE will work without giving the 20% throttle.
@@Zek1701 Thanks for the reply but.... the reason I thought I programmed AS3X wrong , or, the AS3X was acting just like Safe . I found my answer. The difference between the control surface movements, and this might be added to your video, Step 1: manually hold plane upside down in Safe, the control surfaces will fully deflect to right the plane to level flight. Step 2 : without changing the orientation, flip the switch from Safe to AS3X. The control surfaces will pop to neutral. Step 3 Right the plane without touching the sticks. The ailerons will go to an un-commanded Right roll as the plane goes level. They will not pop to neutral until you flick the aileron stick.
I think this is related to the RV-7 EFlite instructions caution but not specifically explained as to what is happening to my plane: "Return the elevator and aileron controls to neutral before switching from Safe Select mode to AS3X mode. If you do not neutralize controls when switching into AS3X mode, the control inputs used for Safe select will be excessive for AS3X mode and the aircraft will react immediately." I have also read in other manuals for EFlite to fly the plane in a level mode before switching between modes. I think the Gyros need an opportunity to neutral themselves.
In summary the missing ingredient for me was that I thought AS3X was not programmed correctly because, unless you move the aileron stick the control surface in AS3X to neutralize the control surface, then AS3X acts initially like the Safe. . I hope I explained this accurately but try this out. In the video I did not see you wiggling the Aileron stick because it is off-screen. Try this and let me know if I am getting this or what I am missing.
@@Zek1701 Thanks, Success! I flew the 1/8 Scale Stinson Voyager yesterday afternoon for the first time and had 4 long perfect take offs, flights, and landings after trimming during the first 1 minute of the first flight. I tested all the flight modes by putting the plane into bad "attitudes" and the Safe mode quickly took control to level the plane perfectly on the first flight. (I took off on Safe.) The values you select for your video are great. Now I'm going to go back to my Partenavia (Graupner twin motor) and add the mode 1 (no AS3X and SAFE mode) .
I'll also add airleron/rudder mix, Dual Rates and Expo, and use the same Dual rate switch I have for the Stinson, and use the same switch for the 3 Flight modes. Again, I can not stress too strongly how well put together your video is, and how ALL the other Spektrum sponsored video guys are seemingly scatterbrained compared to your presentation. You are a natural born instructor! Keep up the good work. Now I have to get working on the Clancy Lazy Bee that my son started in 1997. (I have his permission : - )
@@reasonitout9087 Excellent! Glad you had some successful flights and it worked out. Just remember when taking off in SAFE the receiver will reduce the max elevator. In my case I have a relatively small runway to get my large jets off the ground and I can only get them off in AS3X. Happy Flying!!
@@Zek1701 I agree on this. When taking off and landing in Safe mode I always select Hjgh Rate.
Had one in a Crop duster... Couldnt program , couldnt shut off, had others even try... Was told to replace, which I did and left the receiver at the field for someone else... Good luck your gonna need it...
Mike…. Watch the video. They work and have saved many of my jets.
Saved my F14 in its maiden! ruclips.net/video/TeCPtw-0uJQ/видео.html
Thank you for this good video. If programmed my AR636B now, but Safe behaves strange. All surfaces are corrected in the opposite direction that they should. For example, if I hold the plane with the nose up, SAFE is holding the Elevator more up. Or if I tilt the plane right, Save is correcting it even more right! So the crash is sure if I try it in real life..... Do you know whats going wrong here? Thomas
I would double check the receiver orientation...see video starting at 12:10. This part is very important for the receiver to learn the orientation it has with the aircraft and provide the correct control to the servos, especially the correct direction.
@@Zek1701 checked it, but it is ok…..
@@Mustangschweinderl [Note: these comments are for the Programming AR363B video - not the Fwd Programming video.] Tomii -next look at video 32:20. Go into the Spektrum Progammer program and reverse the control surfaces that are backward. Then test SAFE again.
@@Zek1701 Hey, that was it! Thank you!
Anyway to do this with a dxs transmitter with a ar636B?
No, AR636B does not support Forward Programming.
@@Zek1701 thank you
Will the ar635 do same settings ?
AR635 only has AS3X-no SAFE. To set the one of the 3 AS3X modes does not require Fwd Programming. See:
ruclips.net/video/-ALhC0H5R-M/видео.html
The second problem that I have is that I get an error on the NX8 when I try to forward programm the receiver.... strange.... the firmware on both is the newest... Thank you!
For the AR636B you can not program it with Fwd Programming.
I just bought AR630 for my Freewing F15C, i wonder if anyone knows if that's going to be an issue in the 90m jet. Love to hear anyone thoughts on it.
AR630 is only a 7 channel receiver(Bind/Prog/SRXL2 is a port too). However, is you want to switch between AS3X and SAFE in fly you need to allocate a channel for that. In this case it is a 6 channel receiver. If this is enough it will work fine in any jet. I use AR8360T in an F15 and SU30. AR630 is a variety of 70 and twin 60 jets.
Thanks Zek, yeah, this is my first receiver with the internal antenna. feeling insecure having it in the 90m jet.
@@jetman899 You could get an AR8310T and add a satellite receiver.
Yeah, I’m thinking about it, it will be extra cost and time, but I’d be safe than sorry I guess.
i don't have forward programming shown in my transmitter ! Dx6 !
Why aren’t your trims centered? Gyros don’t like an offset at neutral. They’ll think you’re holding the stick away from neutral. This can cause the gyro to exit heading hold mode, if you have it enabled. If your plane doesn’t fly straight with the trims centered, you need to adjust your linkages so that you can set the trims back to center.
I'm lazy that's why the trims are not centered. The jet flies fine for me and I'm not that anal but the jet setup. I just want to fly and have fun.
A receiver like the AR637T has inbuilt Telemetry.
And what happened when you can't find forward programming? Cause mine is poofed from the options menu! Spektrum Sucks!!!
The receiver needs to be powered on and binded to the transmitter before Fwd Programming shows up in the menu. The reason is you are actually programming the receiver not the transmitter.
Okay..
Excellent👍🏻👍🏻👍🏻👍🏻👍🏻👏🏻👏🏻👏🏻👏🏻👏🏻⭐️⭐️⭐️⭐️⭐️✅✅✅✅✅
No, you don’t have to set up heading hold to make AS3X work. You did something wrong elsewhere.
can you explain please what went wrong ,
Well if you don't set it AS3X doesn't work...if you do set it it does work. As stated I don't know why but I got it to work, So unless you can explain how to get AS3X to work without heading I'll continue with that setup. I'm not an guru on Spectrum receivers I just know how to get it to do what I need.
@@Zek1701 You can set a flight mode to be AS3X only, heading hold only, or SAFE only. Or, you can use all three together. However, heading hold and SAFE are about the same thing except heading hold won’t keep your plane right side up. I think AS3X wasn’t working because it didn’t have any gain. Or, you didn’t open the throttle far enough. I wasn’t watching that close at that point. You got my attention when you said you had to give it a little heading gain. And, I didn’t see if you set the AS3X gains to fixed or left them set to adjustable. If they’re set to adjustable, you have to set up a gain channel and turn the knob up to get some gain. You can see what the gains are actually set to by going into the capture gains screen. The telemetry screen shows the maximum gain, not what the gain is in real time. I’ll watch your video again and see if I can spot what might have happened.
@@Zek1701 You didn't go into the "Fixed/Adjustable Gain" menu and change the gain settings from Adjustable to Fixed. And since you didn't set up a gain control channel, you have 0% gain for all three of the AS3X gains. Go into the "Capture Gyro Gains" screen before you change them to fixed. Then change them to fixed and go look again. Heading hold is a separate entity and is seldom used in Horizon's BNF's. Heading hold only works when the sticks are centered (this is one reason why your trims need to be centered). It tries to keep your plane in whatever attitude it was in when you centered the sticks. You can do aerobatics while heading hold is on and if it's set correctly, you won't need to apply aileron or elevator to keep your plane going straight when you use top rudder in knife edge flight. Without heading hold, you usually have to mix aileron and/or elevator in with the rudder. BTW, the Spektrum engineers put that "RUD > AIL/ELE" mix in there just for that. Smart guys, huh? Incidentally, if heading hold is working correctly, you'll never notice that your plane is out of trim. You can screw up the linkages (within reason), and it'll still fly straight. You have to turn heading hold off to actually see if your plane is trimmed correctly. One of the things about Forward Programming that I don't like is that as you change things, new options appear in the menus. You have to keep going back through every screen multiple times to make sure you haven't missed something.
Also, the pitch attitude trim usually needs to be a positive number or your plane will descend in SAFE mode. It depends on how level the receiver is in the plane, but tricycle-geared planes apparently fly a little more nose-up than they sit on the ground. The SAFE mode gain of 35 for roll is pretty good, but I bump the SAFE pitch gain up to about 55 so that I have enough elevator to take off and land in SAFE mode. To check the SAFE mode gains, I compare the throws in SAFE mode to the throws in low and high rates with SAFE off. I want the SAFE throw to be somewhere in between.
Another issue is the bank/pitch limits. Setting the nose up limit to 75 will allow your plane to climb so steeply that the receiver doesn't know what to do with your aileron input. Basically, it won't turn unless you let off the elevator first. I tried 60 degrees and it was too much. I use no more than 50 for nose up and 30 to 45 for nose down. The bank limit should be based on the speed of the plane, as you pointed out. A slow trainer might need 35 to 45 degrees, a faster sport plane needs about 60, and a fast EDF can use 85 degrees.
@@Zek1701 I’m not sure why the Spektrum engineers made the default AS3X gain setting “Adjustable” when they made the default SAFE gain setting “Fixed”. I guess they assumed people would set up a gain channel and make test flights to find the optimum AS3X gain settings. Now I wonder how many people have run into the problem you had.
Also, the priority value sets the point where the gyro gain decreases to zero. If the priority is set to 100% and the travel and dual rate are set to 100%, the gain will decrease to zero when the stick is at full deflection. If you lower the dual rate down to 50%, the AS3X gain will only decrease to 1/2 of what it was at neutral. We don’t really need or want the gyro fighting us at full stick deflection. So, to get the gyro gain to decrease to zero with a dual rate of 50%, the priority needs to be set to 150%. A priority of 160% will cause the gain to drop to zero with the dual rate set to 40%. Since I never use a dual rate of less than 50%, I set all of my priorities to 150%. However, you probably would never see or feel the difference between 150% and 160%. With an AR636, you can see what the gains are doing as you move the sticks. I couldn’t find a screen where you can see them change with one of the Smart AS3X/SAFE receivers.
