Chad here. I’m the first video. You nailed it! The problem was the camera lens somehow worked itself loose over time. Thankfully a quick fix! Appreciate the help. Btw- I use your Tunes on my 5”, 6” and Phantom 2.5”. So smooth. Excellent work!
Oh… and it’s a 5s battery. Still need to run the numbers and see if I can handle 6s
I posted this on one of JB's old videos but I don't expect he'll respond to me, I'll post it here too cause you've helped me a lot in the past and this video came up when I was searching fly aways.
I was flying in heavy wind, like 30-40mph, the quad had performed great during the flight with no apparent issues, but when I went to land and went to like 10% throttle my quad said nope and took off. I was able to recover it by pitching into the wind more and it seemed fine with that, and ultimately was able to land it pushed over at about 40 degrees and then disarmed once I was able to wrestle it close to the ground, but if I tried to flare at all it would go crazy again. Air mode was turned off, cause it had flown away before after arming and I put it on stock pids, I had it on higher multiplier before.
The frame is really noisy and home built so I guess I just need to lower all my pids rather than raise them? It seems fine in normal flight now though without wind. I guess the wind was causing the quad to oscillate in ways it couldn't predict and feeding back into the pid loop, but I don't know what to lower or raise to stop it from doing that.
I raised the I term and in calm wind it seemed to be more stable and responsive, but not sure if it will have this problem in the wind again, or if that will make it worse.
I have the blackbox for the flight but I can't determine where it happened just looking at the traces, it seems normal to me, the setpoint never seems to be wrong which it clearly was, or what I should change to stop it from happening again.
Excellent as always
I love this format. Very helpful.
Enjoyed this format!
I appreciate this type of video. Thank you
Nice…..Helpful tips and informative, thanks!
Love it
Thanks dude!!!
Very useful info, Mark! Thanks a bunch!!! 😊
Stay safe there with your family! 🖖😊
Nice QA video
nice to meet you. Yeah!fantastic job! have a good day!Uav,
I missed videos like this!
thank you
Thank you
I'm new to elrs myself but I found out it has binding issues if you plug in the quad before the transmitter because the receiver goes into wifi mode so turn everything off then turn on transmitter first then plug in the quad then it should bind
Thanks dude por the input, im the one having this issue, will keep in mind this detail for future sessions, but that could be issue i ran into!
Thanks for the ideas! Visually I just didn’t see the loose lens so getting that idea kept me from digging unnecessarily.
Def alot of good info I'd like to see more of this I also have a 4 inch quad with 2004 3000kv motors on it running 6s when I throttle up I get some weird shakes flies good but Def some issues there
Same here. Mid throttle and up it twitches bad.
any solutions?
@turionb1408
Decrease TPA, check mechanical issues, and - in my very weird case - the AIO was not properly grounded and a grommet was slightly torn creating continuity between the frame and motors only at high throttle, which in turn sent the gyro into a fit.... 😳😳😳
@@nikotttin hey man thanks so much for the response ✌🏻
Yes, change props first I was having shakes on my 7" was using gemfan props installed some master airscrew and it fixed the shakes.
i really like this video cause its called rapid fire and all you doudt clear in sec
Source one v5 had some QC issue with the arms in the crossplate. Mine were terrible causing a ton a wiggle in the arms when tightened. I would check thay first.
Is setting your PWM-Frequency to 16 for "low" and by-RPM for "high" not a thing anymore or did I just totally misunderstand when to do that? ^^
thanks for all your work, Mark!
To the guy who has the flutter issue: There's a chance that something might be wrong with your ESC. I've had something very similar happen on a Skystars AM32 ESC. Firmware upgrades, ESC tweaking, and capacitor changes didn't fix it for me. Finally, I just replaced the whole Skystars stack with a Holybro stack with BL32 and no more flutters on stock BF. I've read in a forum that other people have problems with AM32 based ESCs.
About the binding issue maybe check model match?
I recenty got simmilar issues. Traying to deal with it by myself. What I did was replacing 1103 motors to 1408 in my 3" quad. Then I put on in T3x3x3 instead of orginal T3x2. I got a lot of power on very poor, unstiff frame, much lower rpm, a lot of modulated noise around 200hz. When I set more throttle, it's becoming smooth. Clearly need to go back to old props T3x2 or buy more stiff racing frame...
I've had bad jello before. Accidentally changed to a different pid profile. Another with a bad motor.
hi mark, the last case of hot motors, is there any chance it could be also coming from the filter settings? or this issue is purely esc firmware and PID?
Hot motors could definitely also be a lack of filtering.. Filter Sliders to the Right or(less) increase motor heat but can improve performance.. 👍👍
Tango2 can't provide enough power for ELRS module. It can be work 50mw power only - and without cooler .... also we have the upgrade kit power board for tango2 - the best way to handle it
Loose sensor Definitely happens with dji cams.
Holуbro Tekko 32 sometimes cuts out the rear left motor and drops at a voltage of 3.8 volts per can, on batteries for 4s, then it flies normally 10 times on the same battery up to 3.3 volts, then it drops again 11 times and again the same motor, changed the motor, but it did not help, it flies normally for 6s, sometimes the ESC does not play a melody when connected, it already loses when it is repeated, the batteries are good, the resistance is 4. What could be?
Hi Mate, at the begining you are saying that cables should be checked if they are not touching gyro and FC. Does it mean that cables soldered to the FC should be routed above the FC and let's say, ziptie to the top plate? I mean if they can lay on the FC if they do not touch the gyro or each cable which touches the FC will cause some gyro noise?
if you have shakes, make sure a cable is not slapping the gyro.
@@uavtech I do not have any shakes but I have huge noises in blackbox when arming the quad. I also can not tune my drone according to the YT videos because my logs differ from what I see for other people. I have bought Quadmula Siren F5 Split and it is so noisy that I am freaking out. All screws are tight, motors are tight, I even soft mounted VTX and it is still not good. People set D Gains to 0.8, I have to set 1.3 to avoid overshoots...
Brother I need help Please! i have a 3.5 in quad that was working perfect until i crashed it and broke a motor. i replaced the motor but now the quad acts like i have the motor output limited to 10% . it will arm and it followes the sticks like rocking it back and forth or side to side with the sticks. i have checked everything. all is set right. but no mater how much throttle i give it it is not enough to take off from the ground. i have re flashed everything and tried older versions. checked the esc's in blhelisuit. nothing makes any difference. Do you have any idea where to start> have you ever seen this before? Please help! By the way i build quads for the public so i know what im doing. but this one has me stumped. im to the point of just randomly changing parts. i thought maybe the new motor was weak and the Fc was dumbing down the other motors to match the week one so i took it off and it still does it. it never tries to freak out or anything all seems correct.
Since you said this, it makes me wonder:
"i thought maybe the new motor was weak and the Fc was dumbing down the other motors to match the week one so i took it off and it still does it. "
I would have thought the new motor was dragging down the rest due to the PID loop keeping everything stable.
I would run up each motor in Betaflight configurator and look at the RPM values on each. I would think one of them is not getting up to the full throttle RPM like the others. Maybe an ESC issue?
Camera lens tight?
that's another thing, yes.
That 'fluttery' sound at 13:10 sounds ANGRY to me. and those motors are, probably, not in a great mood
Sir please assist me 😢
It's my first Quadcopter
I flashed baseflight on my naze 32 bmp280
Problem is quad not using midvalue 1500 as its altitude mode as netrual position.
It's using the min throttle value in case of power on the quad>> switch into baro mode>> arm the quad and lift off.
And the value of throttle when you switch into altitude hold mode.
Please help , i want my quad to maintain altitude at 1500 throttle value.
sorry I'm not familiar with Baseflight. That is pretty old firmware.
Guy with jello/ shake, check the camera lens is tight, I have had what looks to be the same thing happen to me mid flight.
Sometimes lenses can have one of the optical elements inside come loose, too
Oh hell yeah my brother. Thanks for this information. You saved my ass. I’m gonna go figure out. What the hell happened to the squad copter. Son of a bitch landed on somebody’s car. It’s OK though because my neighbor doesn’t care. He has a really crappy car. He’s cool. Anyway I need to go fix that son of a bitch.
Figure out your ideal rates, and then the Sim flies perfectly every time like a dream.
FPV started in a futuristic sim on my server, not RC. The dmmning evide is in it's name.. FPV. Toy crrp in the sky is always going to fly like junk. And if it don't now, it will after you crash it. Leave the old inferior 1970's paradgm junk RC behind. It's the sorriest hobby ever.
Not if you fly in awesome IRL spots
real life flying is a 100 times more fun than sim. I crash lots, sometimes stuff breaks, usually it doesn't. totally worth it
@@fearlessflyersfpv420 no it's not. i've done both. baking in the hot sun with an alien face hugger pair of goggles on you and futzing around with sorry a55 equipment is no fun at all.
@@choppergirl i fly every day, probably ten packs, in real life. I have sims, and never play them, it's boring for me. If my drone or something dies and I can't fly for real, I may pull up a sim, but for me, sims suck, real life flying is awesome. Learn how to build strong and shit hardly ever breaks. If you prefer sims, that's you, most people love real life flying much better.
Real world for me. I don't play video games and flying sims feels like that to me. Some times struggle gives the most joy. Like sports. Winning a hard game feels better than winning a blowout.
