Locking one diff as opposed to both at the same time is usually used to get around tight obstacles. Locking the front around turns will pivot around and hold a tighter turn where as the back locked tends to push and create a wider turn. Having the front only locked going up steep inclines can also keep the vehicle planted where as the rear locked can cause it to flip over backward.
I think you have that backwards when you lock the front diffs the wheels turn at exactly the same speed making it hard to turn, locking the back diffs have the same effect to a lessor degree. I pulled this from Google, Fully locked differentials are never used in front-wheel drive vehicles due to the negative effects on handling. They will suffer from severe understeer on early to mid-corner turn in. Torque steer can also be a problem, even on low throttle inputs.
@@RCOverKill You are correct, when applying locked differentials to on road which you should not do anyways. However there are always exceptions to every rule. Google is not always correct. What you are refering to is on road normal driving situations. In that situation you should not have any differential locked, front or rear, except maybe the exception of snow and ice. The situation I described is not a typical daily driving situation. It is and off road or crawling situation.
I like having independent control over each diff. There are times when unlocking just the rear will keep the truck from pushing the front wheels off line.
Welcome to the surface radio controlled world. Good to see other companies selling nice radios for less $$ than futaba & spektrum. And anything is better than that stock traxxas "4" channel radio. Good to see your having fun. Might get me back onto my surface rc's again. Been a couple years.
Unlocking the steering axle will help tighten turns. A lot of buggies w/4wheel steer use all types of combinations to cut in or out power to each of the 4tires independently
"SA" switch is a 3 position switch just below the steering wheel that will function the same as the original TQi remote. Save your toggles for lights!!! 😊
Locking the front diff and not locking the rear diff allows for better turning in most situations. The front end is "pulled" around by both front tires, and having the rear unlocked helps this a lot. Locking just the rear diff and not locking the front diff would make the truck "push" through turns and not handle as well, but it could make it "drift" better on slick surfaces. The settings make sense for what the truck was intended for.
Again thanks for being one step ahead of me 👍🏻 Personally I want the ability to lock each differential independently, as some situations require to unlock the rear and basically drag it in sticky situations, where you need to only be pulling from the front. Usually in technical crawling problems. Hard for me to explain, you would just have to watch some “TRX4 technical rock crawling” videos to really understand. This definitely gets me 85% there though. Will maybe use SC or SB for the low and high, and the two position switches for my lockers, which will actually give the truck an ability that it doesn’t have from the factory. The ability to lock only the rear. I sooo dig this transmitter. It’s the main reason I have over 2Gs in RC cars now, when I haven’t owned one in 25 years(tons of quads though)
Thanks for the video...used it as a base and tweaked it a little. I used the two add on switches for the front and rear diff locks. That way you can have all combinations. I then took SD, which is the 3 position switch under the wheel and changed it to be a 2 position switch. I was able to use it as the two speed selector switch. This setup works awesome!!!
The land enthusiasts are very different than your air enthusiasts. There’s a lot of RCs abuse, trash talking, and egos in the land community. You’ll see. Lol. But thanks for these land videos with this radio. I’m just getting used to the programability of the Dumbo DDF-350 and then heard about this Radiomaster. I ordered the 4in1 and the Ranger module separately because I bought it more so for the multi model storing. I have a lot of Dumbo receivers and it’s great that this radio binds with them. I’m also about to setup my first fpv vehicle as soon as all the equipment delivers. I subbed!
This EXACTLY the video I asked for when, you posted the TRX transmitter vs. FPV transmission. I somehow ended up with a new TRX4 2021 Bronco about a week and a half ago. I already have my Sledge bound(thx to you) and now I will soon have my TRX4 on the MT12 and ELRS. I have so many projects in the works, I don’t know if I would have found the time to figure it out for awhile. I’m a long time patron, and thankful for your help as always!
That's what I do, Bardwell is behind the times with his setup because I've been driving FPV for years now and using the phone to change setup is so much easier to do than messing with the Radio master he has and I forget how many models in memory the Traxxas radio has with the link but it is a lot and the Traxxas radio has built in battery and radio link telemetry
The BT module is way too expensive and firmware updates take ages. Also I'm not a fan of needing my phone to access the car's programming or accessing telemetry. The Traxxas radios aren't bad, don't get me wrong, but only if you take it as it is. If Traxxas doesn't provides a certain feature you're out of luck.
Missed opportunity to show how to program in cruise control (locking throttle with a button, but also using brake to cancel, and the knob to fine tune cruise speed, and ALSO the trigger to momentarily increase cruise speed). It took me a while but I got to use global variables, a bunch of different logical switches and special functions, the “add after” mixer functions, I learned so much. I’m a nerd like JB so for me it was just fun to think about how I would use the available functions to solve a complex problem.
Tires turn it different speeds on an axle as you go around a corner. When you lock the diff, it makes both tires spin exactly the same speed, even when going around a corner which can make you hop and not turn as tightly. Same goes for the back, your outer tire on a turn is always spinning faster than your turning tire
Sdtig148 explained it correctly. Just imagine when a race car takes off the front nose lifts up so is you lock the front diff only on your rc then the back wheel won’t pull the front nose more away from what the front tires are trying to grab friction from. You be pulling yourself up not pushing. Great Vid Joshua. Hope you open a whole new viewers. This is something new the ground rc is looking into. 👍
Hi Josh, I just purchased the Radiomaster MT12 and I can't wait to setup my rockcrawler. But I did something different. I installed a servo for I can use 4wheel steering, with a twist. I want front steering, rear steering, crab and together. For years I have been looking for a radio that I can do everything with, I found a couple of radio's but they were so expensive I had to pass. Can't wait for the next video on the Radiomaster MT12
@@JoshuaBardwell I just saw it when I viewed your video page 👍. I am definitely a noob to fpv and your videos have helped a lot! Looking to get a radio master tx16s soon to start flying in drone simulators. Thank you for your quality content!
Well, I just got one ordered. Picked up an 8 channel receiver so I can install the selectable 2wd on my TRX-4 and control the diff locks individually. Might even see if my winch can run off the radio as well.
I would reccomend to use the bottom switches for Ch 4 and ch 5 seperatly, because you want to choose, which diff is locked and switch the gears by using SC at the handle
If you are rock crawling and you're trying to get up a ledge and one of your rear tires has more traction than the front, a rear locker will flip ypu over backwards. With just the front locked it can pull up without flipping over.
Excellent content, as usual. I'm hoping that your new rc vehicle videos bring a whole new group of hobbyists to a different aspect of the hobby, and vice versa. Could you possibly make a video showing how to bind to Traxxas TSM or Flysky FS-BS4 receivers to gather telemetry data and modify the gyro? Thanks!
Since you’re going to have diffs on or diffs off, I think you could use a y cable and put both servos on one channel. Then you could use the other channel for lights or a winch.
Few things holding me back from putting any of my traxxas vehicles on the TM12 missing from this video, I’ll definitely be putting my other cars on the TM12. 1. Do you lose TSM (stability management) the multifunction knob next to the steering knob? 2. I’m guessing you’ll lose the ability to update your esc and change the settings with no traxxas Bluetooth link? Not the end of the world tho 3. Is there a way to get the speed motor temp telemetry working without the traxxas Bluetooth link? Also you need to recalibrate the esc using a new TX you may lose resolution on throttle/steering, important step should be mentioned (hey whys my car so slow now 😂) Great vid for swapping your car over to the TM12, not sure it’s worth losing traxxas system just yet, TSM would be great to get that working and would almost be enough for me, motor temp and speed be great but I bet most don’t use the BT link anyway, can always update esc before you swap over.
The front locks on its own to get around turns better since the front has more grip and switch all the way it does both for those real sticky situations lol u could do just the rear but it would spin out easy in the front and possibly making the rear slide out on u
THanks man, informative video :) Got my MT12 Radio yesterday and I will start by binding it to a more simple car before going about and mess with the TRX-4 :)
I like my MT12 but I've put it away until EdgeTX Companion supports it. I've always found the best thing about OpenTX/EdgeTX was setting up & testing complex models in companion.
Just an observation. The model template you are using is still using the default and incorrect channel order of Throttle on Ch1 and Steering on Ch2 (10:00 in this video) but when moving the plugs across to the new ELRS RX you state that you follow the Traxxas order which puts Steering in Ch1 and Throttle in Ch2. There is no way that will work and is bound to cause confusion for those new to EdgeTX and this radio. This has the potential to get even more confusing when more complicated mixes are developed as some users (like me) will have amended the channel order at the outset and some won't. Other content creators will add to the confusion as some will have the correct channel order and others won't. Perhaps we need a caveat at the start of each video stating the channel order used?
@@JoshuaBardwell That's good to know. I really can't understand why they shipped the MT12 with the incorrect channel order as every wheel radio out there has steering on ch1 and throttle on Ch2. Talk about making it more confusing for those new to EdgeTX
I never got into RC cars but did have a few RC boats as a kid. Maybe become the RC Know-It-All! Tho i have to say no other RC hobby came close to holding my attention for as long as quadcopters
I'd be nice if the MT12 (4 in 1) could bind with a TRX4M (the small ones) without changing anything on the crawler truck. Maybe RADIOMASTER will release a fix for that soon. The MT12 has a TRAXXAS sub-type protocol called "6519", but the TRX4M has something else in it. Trying to bind them is a NO-GO!
What system you're using depending on your setup an setup location can cause the vehicle to flip its very weight sensitive in my experience wasnt much fun till I got a traxxas slash just my experience
@@Revelation1177 I have no issues my Mach 3 is mounted under the battery tray and doesn’t affect articulation, I think it adds some weight down low the camera sits inside behind the windshield on a 3D printed mount, I think it’s pretty easy to chose a light enough setup with all the video transmission systems offered down to sizes that fit on whoops and micro quads, I have a ton of fun and limitless range with the little scx24 I’m running. In my experience it’s more difficult putting a video system on a more high action vehicle, very prone to damage from flipping but there’s a good way to do anything and I had fun with a camera on a 1/16 vxl e revo for a short time
Those traxxas ones are hard to remember to shut off, luckily the batteries tend to last, I am one of those guys with too many controllers, that’s why I’m switching to Elrs with the mt12 for my rc cars, now I just need to figure out how to put in a gyro so I can maintain traxxas stability management on the steering
I just purchased the Radiomaster MT12 surface radio. I’m trying to create a “launch control” function (for drag racing). I need to be able to adjust throttle percentage and the time it takes to clear that range, i.e. 0-30% throttle in .5 second. I would like to be able to create multiple stages like this, i.e. 0-30% in .5sec, 30-45% in .2sec, etc. I would like to have multiple stages (at least 8 possibly more). I would like to be able to toggle the stages off and on the fly i.e 2 stage launch or 8 stage launch or any option in between. I would also be looking to adjust the throttle percentage and stage time on the fly i.e. 0-30% in .5sec to 0-35% in .45sec on the fly. For ease of use I would like the maximum level of the previous stage to control the minimum level of the next stage, i.e. a 5% increase in stage 1 from 0-30% to 0-35% would make the minimum of stage 2 go from 30-45% to 35-45%. I got this radio because I love to tinker. I’m totally new to edgeTX but I’m excited to figure out how to utilize the software. I am not looking for someone to do all the hard work for me, just point me in the right direction. This would be like the seed control function in the Futaba 7PXR TIA
Just got my mt12 for my birthday and love the video but one thing them Tiny servo don't need to be at 100 percent throw out you find out they tend to other burn out our strip teeth. Moving from my spectrum rugged and there less then 30 percent throw. When I was getting the truck the guy sold it to me said get a few of them tiny blue servos be cus they go out well going on 4 years on the same ones. So you have a play list for the mt12 id like to see it
This is a great video, I've been wanting to do this for a while and with this video the process will be a breeze. So I guess you don't need a laptop or a smartphone to connect the RX to wifi with a land RX
Can you make a video showing how to setup MT12 4 in 1 to work with Spektrum Receiver (SR6200A) with AVC configured to pots? I can’t find any videos detailing this setup.
Does this rc allow mount external crsf-protocol module? Betafpv introduced elrs series 'super' with gemini mode (2 antennas with different frequency instead of one frequency that we used to with simple divercity) and it worked for me wery good on the earth. Have you tried it? Btw, my car with betafpv superP + radiomaster pocket drived 450m (until av lost) on flat surface with no obstacles and Icve still got 90lq
Love your videos, but you're missing a lot of very important info. On quads with flight controllers we dont worry about sub trim and endpoints and such as much. Proper servo setup with PWM is vital or people are going to be burning out their gear in no time.
I came to the comments to say the very same thing. The micro servos for diff lock and 2-speed can easily burn out if proper endpoints aren't set. While it might LOOK like they are set correctly, endpoints still need to be adjusted to verify that everything is adjusted correctly. Also, centering the steering servo needs to be done as well as setting steering endpoints. You can destroy the CVDs and or burn out the servo if the endpoints are set too far out.
Hey maybe you can answer this question I have about pwm receivers. Can they control a digital servo or do you need a different digital receiver? I want to use elrs for my cars but one has a digital servo for turning. Thanks, like the video!
Joshua; is there a way to get sound? I have the walksnail and no sound on that system. Wondering if there are alternitive ways without replacing that system. Or is DJI going to be the only way. If so what DJI system is available. Surface FPV maybe a bit bigger than you might think now that there are digital plug and play systems out. These system are fairly new and more and more surface users are adopting it now. Scale detail in crawlers is HUGE and it dont get anymore scale than putting yourself in the drivers seat.
Hi Joshua, do you happen to have a complete video tutorial on how to set-up the MT12 with the TRX4 from scratch? I mean like from binding it. I am getting frustrated as i am not able to make it work lol i got the 4in1 version so i tried to bind it with the original Traxxas receiver but it doesnt seem to work and so i attempted to swap the receiver but the only thing working is the forward/reverse but its function as left and right. I followed the channel wire set up based from the original tqi rx. Please advise.
Hey Joshua👋🏻 Im looking forward to get the Getfpv DIY Kit freestyle Drone Kit from you for my birthday and i wanted to buy the NewBee Toolkit. Should i get a “better” Soldering iron or something like that or do i have everything i need in that Kit? And do NewBee Drone and GetFPV ship to Europe?
Honestly, the soldering iron in the NBD toolkit is ok. I think you can get done what you need to get done. As for shipping, you will have to ask the individual company what their policy is.
Great RM have made a surface radio, there’s two choices elrs or the 4in1 which one do you choose? I run ghost in my air crafts and obviously if your going to fpv your car which not many will do is there really an advantage going elrs or would the 4in 1 be better seen as it binds to a lot of rtr cars available? Pros n cons?
With the 4 in 1 You would be stuck with whatever channels are on the existing receivers so you wouldn’t be able to take advantage of all the extra switches and capabilities of Edge TX. IMO the elrs version is the one to get because of the extra channels
Great content!! 18:11 Do you know how to get full telemetry(volt,amp,rpm)with ExpressLRS and blheli32 single escs? It's possible with frsky receivers thru s.port but with ExpressLRS i dont understand if it's possible
joshua i have a traxxas 6533 rx in my high trail blazer. can i leave the rx the same and bind to my 4 in 1 module? that way i could still keep the traxxas pro light kit that plugs into the traxxas rx. i understand the diffs and hi and low gears but the light kit has a different harness that the 6533 rx accepts. i dont mind changing rxs as along as i can get lights to work also
Hey I have a question related to ELRS, would it be possible to turn a old transmitter into a sort of relay for boosting RSSI when flying/driving long distances or deep penetration in a building for filming purposes? I have seen something similar done for the Red Bull video but it wasn't really covered how they did it.
quick question for you, ive looked to see if you have covered this yet but i dont see it. ive been trying to take a channel on the erls receiver and make it switches for the lights on my cars. ive tried 2 diff. ways and i cant figure it out. any help would be great.
added the 2 position switches, but they are not working. When I go to the "debug" settings the switch positions do not change. FL2 does not even show up. Thank you so much for your videos!
sorry if its sound dumb, but i really beginner in this field so the elrs version cant connect to another receiver like 4 in 1 version? am i right? or maybe elrs version can connect to another receiver but not as much as 4 in 1 version?
hey joshua. great videos. i am thinking of buying the mt12 but dont know which version. i have about 4 different vehicles now and want to get them on 1 radio qnd they have different rxs. i also want to use the eslr rxs for future vehicles. i was thinking of getting the 4 in 1 radio and adding the external elsr module. that would give me the best of both worlds i think.what are your thoughts?
No concerns about the weirdo Channel 5 thing that ELRS does? I moved my second diff to Channel 6 and then in the ELRS settings had the receiver output channel 6 on pin 5. That way I could leave channel 5 high, which supposedly brings the ELRS module to full features?
Frankly, unless you are using dynamic power, that option shouldn't matter too much for surface vehicles. So just set output power static and be done. But the workaround you described is the correct one.
If you install the Bluetooth module in the TQi transmitter, you can use the transmitter with 40 cars. I have four Traxxas transmitters and just got a ELRS MT12 with 4 in 1 module and four additional receivers. Thank you for your videos.
Since the software was written for aircraft including drones, I understand the protocol labeled Traxxas is for the Traxxas drone radios. I have heard that the "43" protocol will work with Traxxas surface receivers. Traxxas states there is no limit tot he number of models a TQi transmitter can bind. My goal is to use my MT12 to bind to Traxxas, Futaba, and Radiomaster receivers.@@swissfreek
The chips were the voltage regulator, I just plugged the F4 into the USB to see the parameters, and the chips started burning, I unplugged them, but I did not understand whats happened.
just lock your difs and try do make a tight corner... it wont work, because the outer weels in the curve make more revelution than the inner ones. because of the diffrent radius of the left and right wheel

The front locks on its own to get around turns better since the front has more grip and switch all the way it does both for those real sticky situations lol u could do just the rear but it would spin out easy in the front and possibly making the rear slide out on u
The ability to lock just the front diff is for some certain situations when you need to do precise maneuvers.
there's a second antenna holder/spot just to the right of the receiver you can use.
Love the surface rc content i been flying quads for a few years just got into fpv surface rc cars its so much fun 😂
Fantastic, Joshua! Thanks for the tutorial! 😃
Stay safe there with your family! 🖖😊
THanks man, informative video :) Got my MT12 Radio yesterday and I will start by binding it to a more simple car before going about and mess with the TRX-4 :)
I like my MT12 but I've put it away until EdgeTX Companion supports it. I've always found the best thing about OpenTX/EdgeTX was setting up & testing complex models in companion.
You lock the front only for tight turns or digging on a hill. Locking the rear severely reduces the turning radius. Locking both is max traction
I went from cars to drones and back to cars. I know your a drone guy but look into an X-maxx next. You won't be disappointed.
Just an observation. The model template you are using is still using the default and incorrect channel order of Throttle on Ch1 and Steering on Ch2 (10:00 in this video) but when moving the plugs across to the new ELRS RX you state that you follow the Traxxas order which puts Steering in Ch1 and Throttle in Ch2. There is no way that will work and is bound to cause confusion for those new to EdgeTX and this radio. This has the potential to get even more confusing when more complicated mixes are developed as some users (like me) will have amended the channel order at the outset and some won't. Other content creators will add to the confusion as some will have the correct channel order and others won't. Perhaps we need a caveat at the start of each video stating the channel order used?
The file that is linked in my dropbox has the channels in the correct order.
@@JoshuaBardwell That's good to know. I really can't understand why they shipped the MT12 with the incorrect channel order as every wheel radio out there has steering on ch1 and throttle on Ch2. Talk about making it more confusing for those new to EdgeTX
@@heady2008one to turn two to burn lol he's a fly boy he probably a little too smart for us ground dwellers 😂
I never got into RC cars but did have a few RC boats as a kid. Maybe become the RC Know-It-All!
Tho i have to say no other RC hobby came close to holding my attention for as long as quadcopters
I'd be nice if the MT12 (4 in 1) could bind with a TRX4M (the small ones) without changing anything on the crawler truck. Maybe RADIOMASTER will release a fix for that soon. The MT12 has a TRAXXAS sub-type protocol called "6519", but the TRX4M has something else in it. Trying to bind them is a NO-GO!
Currently waiting for the mt 12 for my fpv scx 24 setup, can’t wait!
What system you're using depending on your setup an setup location can cause the vehicle to flip its very weight sensitive in my experience wasnt much fun till I got a traxxas slash just my experience
@@Revelation1177 I have no issues my Mach 3 is mounted under the battery tray and doesn’t affect articulation, I think it adds some weight down low the camera sits inside behind the windshield on a 3D printed mount, I think it’s pretty easy to chose a light enough setup with all the video transmission systems offered down to sizes that fit on whoops and micro quads, I have a ton of fun and limitless range with the little scx24 I’m running. In my experience it’s more difficult putting a video system on a more high action vehicle, very prone to damage from flipping but there’s a good way to do anything and I had fun with a camera on a 1/16 vxl e revo for a short time
Those traxxas ones are hard to remember to shut off, luckily the batteries tend to last, I am one of those guys with too many controllers, that’s why I’m switching to Elrs with the mt12 for my rc cars, now I just need to figure out how to put in a gyro so I can maintain traxxas stability management on the steering
I just purchased the Radiomaster MT12 surface radio. I’m trying to create a “launch control” function (for drag racing). I need to be able to adjust throttle percentage and the time it takes to clear that range, i.e. 0-30% throttle in .5 second.
I would like to be able to create multiple stages like this, i.e. 0-30% in .5sec, 30-45% in .2sec, etc. I would like to have multiple stages (at least 8 possibly more).
I would like to be able to toggle the stages off and on the fly i.e 2 stage launch or 8 stage launch or any option in between.
I would also be looking to adjust the throttle percentage and stage time on the fly i.e. 0-30% in .5sec to 0-35% in .45sec on the fly.
For ease of use I would like the maximum level of the previous stage to control the minimum level of the next stage, i.e. a 5% increase in stage 1 from 0-30% to 0-35% would make the minimum of stage 2 go from 30-45% to 35-45%.
I got this radio because I love to tinker. I’m totally new to edgeTX but I’m excited to figure out how to utilize the software. I am not looking for someone to do all the hard work for me, just point me in the right direction.
This would be like the seed control function in the Futaba 7PXR
TIA
Great project! What would be involved in adding a rear-view camera (to check for cars overtaking)?
Just got my mt12 for my birthday and love the video but one thing them Tiny servo don't need to be at 100 percent throw out you find out they tend to other burn out our strip teeth. Moving from my spectrum rugged and there less then 30 percent throw. When I was getting the truck the guy sold it to me said get a few of them tiny blue servos be cus they go out well going on 4 years on the same ones. So you have a play list for the mt12 id like to see it
Hello, have you experienced a loss of signal at close range? Some people seem to be concerned.
Thank you very much for your videos
This is a great video, I've been wanting to do this for a while and with this video the process will be a breeze. So I guess you don't need a laptop or a smartphone to connect the RX to wifi with a land RX
Can you make a video showing how to setup MT12 4 in 1 to work with Spektrum Receiver (SR6200A) with AVC configured to pots? I can’t find any videos detailing this setup.
Let's FPV a boat and ELRS
Does this rc allow mount external crsf-protocol module?
Betafpv introduced elrs series 'super' with gemini mode (2 antennas with different frequency instead of one frequency that we used to with simple divercity) and it worked for me wery good on the earth. Have you tried it?
Btw, my car with betafpv superP + radiomaster pocket drived 450m (until av lost) on flat surface with no obstacles and Icve still got 90lq
Yes it does.
I sold my trx4 (landrover defence) on new years eve to fund my gradual swap over to digital gear
I really appreciate all the stuff you do but I really wish you would do a series of videos on fpv wings and inav.
Love your videos, but you're missing a lot of very important info. On quads with flight controllers we dont worry about sub trim and endpoints and such as much. Proper servo setup with PWM is vital or people are going to be burning out their gear in no time.
I came to the comments to say the very same thing. The micro servos for diff lock and 2-speed can easily burn out if proper endpoints aren't set. While it might LOOK like they are set correctly, endpoints still need to be adjusted to verify that everything is adjusted correctly.
Also, centering the steering servo needs to be done as well as setting steering endpoints. You can destroy the CVDs and or burn out the servo if the endpoints are set too far out.
Don’t forget the cruise control feature from the Traxxas radio.
Hey maybe you can answer this question I have about pwm receivers. Can they control a digital servo or do you need a different digital receiver? I want to use elrs for my cars but one has a digital servo for turning. Thanks, like the video!
You need a different receiver.
Joshua; is there a way to get sound? I have the walksnail and no sound on that system. Wondering if there are alternitive ways without replacing that system. Or is DJI going to be the only way. If so what DJI system is available. Surface FPV maybe a bit bigger than you might think now that there are digital plug and play systems out. These system are fairly new and more and more surface users are adopting it now. Scale detail in crawlers is HUGE and it dont get anymore scale than putting yourself in the drivers seat.
Actually now that you are doing this now, I think you are going to have a big impact on further Surface FPV adoption.
Hello. Could you explain how to use a single drone ESC for an RC car? Also, how do I update the firmware and tune it for a crawler? Thanks!
That Traxxas looks awesome. Too bad it is so expensive 😢
What about correctly setting steering, throttle and servo endpoints? That would seem to be important!
He did that in the previous MT12 videos I believe.
Great stuff JB!
Hi Joshua, do you happen to have a complete video tutorial on how to set-up the MT12 with the TRX4 from scratch? I mean like from binding it. I am getting frustrated as i am not able to make it work lol i got the 4in1 version so i tried to bind it with the original Traxxas receiver but it doesnt seem to work and so i attempted to swap the receiver but the only thing working is the forward/reverse but its function as left and right. I followed the channel wire set up based from the original tqi rx. Please advise.
We're you able to have it bind with the stock trx4 receiver? Just got the MT-12 under the impression it would bind with Traxxas receivers.
Hey Joshua👋🏻 Im looking forward to get the Getfpv DIY Kit freestyle Drone Kit from you for my birthday and i wanted to buy the NewBee Toolkit. Should i get a “better” Soldering iron or something like that or do i have everything i need in that Kit? And do NewBee Drone and GetFPV ship to Europe?
Honestly, the soldering iron in the NBD toolkit is ok. I think you can get done what you need to get done. As for shipping, you will have to ask the individual company what their policy is.
Hello, I noticed you didn't set the epa on the servos. Why is that? Do the end point automatically set?
Joshua, during binding: Can I use a 1s battery with JST connector, connecting it to port 2 on the ELRS RX to cycle three times to start the bind?
I did it with a 9v battery but it says it takes up to 12v in the specifications
@@xxkc007xx2 cool, I can use a 2s battery with a JST connector and an inline switch so I don't have to stab the rx three times lol
Great RM have made a surface radio, there’s two choices elrs or the 4in1 which one do you choose? I run ghost in my air crafts and obviously if your going to fpv your car which not many will do is there really an advantage going elrs or would the 4in 1 be better seen as it binds to a lot of rtr cars available? Pros n cons?
With the 4 in 1 You would be stuck with whatever channels are on the existing receivers so you wouldn’t be able to take advantage of all the extra switches and capabilities of Edge TX. IMO the elrs version is the one to get because of the extra channels
@@funeralatpizzahut I’ve got an EdgeTx radio so Elsr it is thanks mate 👍🏻
How about the Radiolink RC8X with built in split screen fpv and it is Crossfire compatible?
Great content!!
18:11 Do you know how to get full telemetry(volt,amp,rpm)with ExpressLRS and blheli32 single escs? It's possible with frsky receivers thru s.port but with ExpressLRS i dont understand if it's possible
joshua i have a traxxas 6533 rx in my high trail blazer. can i leave the rx the same and bind to my 4 in 1 module? that way i could still keep the traxxas pro light kit that plugs into the traxxas rx. i understand the diffs and hi and low gears but the light kit has a different harness that the 6533 rx accepts. i dont mind changing rxs as along as i can get lights to work also
Hey I have a question related to ELRS, would it be possible to turn a old transmitter into a sort of relay for boosting RSSI when flying/driving long distances or deep penetration in a building for filming purposes? I have seen something similar done for the Red Bull video but it wasn't really covered how they did it.
quick question for you, ive looked to see if you have covered this yet but i dont see it. ive been trying to take a channel on the erls receiver and make it switches for the lights on my cars. ive tried 2 diff. ways and i cant figure it out. any help would be great.
Always thought JB was a crawler than a fly by type guy.
First ditch the brush motor and use hobby wing fusion pro pnp.
How to adjust lights via elrs, add pwm switch only?
added the 2 position switches, but they are not working. When I go to the "debug" settings the switch positions do not change. FL2 does not even show up. Thank you so much for your videos!
Check the plug?
So, I continued with the setup, and the switches work fine. they just don’t show as working in the debug screen. Maybe a bug?
sorry if its sound dumb, but i really beginner in this field
so the elrs version cant connect to another receiver like 4 in 1 version?
am i right? or maybe elrs version can connect to another receiver but not as much as 4 in 1 version?
hey joshua. great videos. i am thinking of buying the mt12 but dont know which version. i have about 4 different vehicles now and want to get them on 1 radio qnd they have different rxs. i also want to use the eslr rxs for future vehicles. i was thinking of getting the 4 in 1 radio and adding the external elsr module. that would give me the best of both worlds i think.what are your thoughts?
Yes it would, but you would want to verify before you bought the 4-in-1 that the 4-in-1 can bind to your receivers.
Can you make at32 video more detail with beta flight?
No concerns about the weirdo Channel 5 thing that ELRS does? I moved my second diff to Channel 6 and then in the ELRS settings had the receiver output channel 6 on pin 5. That way I could leave channel 5 high, which supposedly brings the ELRS module to full features?
Frankly, unless you are using dynamic power, that option shouldn't matter too much for surface vehicles. So just set output power static and be done. But the workaround you described is the correct one.
@@JoshuaBardwell ok so it’s just dynamic power. Yeah not super important for these types of ranges.
can you share your trx4 file like you did for your other car
Need help I have one speed boat and it flips upside down and I have a recovery boat to go get the speed boat. How do I switch between the receivers?

If you install the Bluetooth module in the TQi transmitter, you can use the transmitter with 40 cars. I have four Traxxas transmitters and just got a ELRS MT12 with 4 in 1 module and four additional receivers. Thank you for your videos.
Yes but only Traxxas cars, right? Also this model of receiver will not bind to the 4-in-1 module. I tried.
Since the software was written for aircraft including drones, I understand the protocol labeled Traxxas is for the Traxxas drone radios. I have heard that the "43" protocol will work with Traxxas surface receivers. Traxxas states there is no limit tot he number of models a TQi transmitter can bind. My goal is to use my MT12 to bind to Traxxas, Futaba, and Radiomaster receivers.@@swissfreek
Will ER5C V2 work with TX16S?
It should as long as you have the ELRS module on your TX16S
any one know if they added a three position switch?
Stick a fusion se 1800kv in that beast and you will have Uber smooth throttle response..direct power 12v servo to..rc crawling isn't ousted just yet..
Day 1 of asking we’re the products roundup are
Yooo he got a traxxas lesgo
Guys I had burned one of the chips of my FC, its was a F4 vs3 plus, I wanna understand what I did wrong, or happened, some one can help me?
The chips were the voltage regulator, I just plugged the F4 into the USB to see the parameters, and the chips started burning, I unplugged them, but I did not understand whats happened.
Do a Theo Vaughn impersonation.....jk jk, while i was listening, and not watching, i expect a " yeah man, you gotta unplug that receiver man."
Easy way to remember turning and throttle channels for unewbies out there, 1 to turn and 2 to burn lol
You better not guilt trip me into a patreon sub this episode bardwell id like to see you just list the good things patreon members get
just lock your difs and try do make a tight corner... it wont work, because the outer weels in the curve make more revelution than the inner ones. because of the diffrent radius of the left and right wheel
Traxxas has 30 memory
