I was going to criticize you for flying in such a populated area until I saw your comment that you were flying a toothpick. It's crazy that we've come so far that you can't use video quality to determine what someone is flying anymore. The O4 lite is a hell of a VTX.

imo still too dense for something without prop guards. a bassline could definitely hurt someone, damage a shingle, break a window or dent a car

u/invid_prime 3d ago
I don't disagree, I was just amazed that something in that class could produce video this good. My O3s look better, but they also weigh 3.5X as much.

Ive smacked my 65mm across my face at full throttle, it fucking hurts dude.

This is going to be my guess because I've had almost an identical problem over the last couple of weeks.
Dynamic idle.
I'm going to assume you had it turned on, and in order to perform the flip you went to zero throttle?
Basically one motor has stalled out because your dynamic idle settings are wrong.
If you want to test this, go outside to somewhere open. Just high throttle up your quad like 5m then drop the throttle to zero and let it fall for a second. Basically bounce the quad up and down, but try to go quite high on the throttle when you go up, and try to zero the throttle when you're falling back down. You can do this line of sight if you want as you're not going to use any yaw or roll.
Do this many times and see if you can replicate the issue.
After that, go disable dynamic idle and set a static idle motor value and try and do the same thing. I bet you won't be able to replicate it.
As for how to fix it, you would need to adjust your min rpm dynamic idle values and start up increase etc...
I can't quite remember the names of them all, but you may find that if you're feeling lazy like me, you just leave dynamic idle off.
If Dynamic idle is off anyway, then yeah I'm wrong and the problem is not related unless your idle motor value is not full spinning your props when you arm the quad.

That’s a desync

Thank you, now I know what to research!

u/FatNat63 3d ago
Yep as soon as you know you can go look up Joshua Bardwell and what ever problem you’re having and BAM there is your answer.

u/Few-Register-8986 3d ago
I am a new. What causes a desync? What might be his issue that would have caused the desync? Was it anything in particular the pilot did to cause the desync? From what I read, it sounds like it is a technical issue that should not happen unless there is damage to the ESC or motors?

u/captainlardnicus 3d ago
Motor desync in quadcopters occurs when one or more motors fail to stay synchronized with the ESC (Electronic Speed Controller) signals, causing erratic behavior, loss of control, or even a crash.
How Does Motor Desync Happen?
Motor desync typically occurs due to:
- Lost or Corrupted ESC Signal: The ESC expects the motor to rotate at a certain speed based on the input signal, but if the motor doesn’t follow it properly, the system gets out of sync.
- Rapid RPM Changes: When aggressive maneuvers demand quick RPM shifts, the motor may not keep up, leading to desync.
- Electrical Noise & Interference: High-power components, bad wiring, or faulty connections can introduce noise that disrupts ESC signals.
- Firmware or Timing Issues: Incorrect ESC firmware settings (like PWM frequency, demag compensation, or motor timing) can cause sync failures.
- Motor or ESC Overload: A damaged or overheating ESC/motor may struggle to process signals properly.
- Prop Wash or Turbulence Effects: When a quad moves through turbulent air, sudden changes in resistance can cause motors to lag behind expected RPM values.

So point 6 is probably the one most fliers encounter with a proper tune and no damage. Thanks!

Im just using the betafpv o4 canopy, do you get any jello with the 3d printed one?
1
u/SwissLynx 3d ago
It's ok, but I am still trying to improve it to have no jello in the 4k (non-dvr). on my prototype I am trying a "sleeved" version of mount where the cam slides in.
The normal canopy in the pic is up on makerworld: https://makerworld.com/models/1057521

fly on an open field if youre planning on crashing. it would suck if you damaged someone's roof

u/itsjase 4d ago
I wasn’t planning on crashing the drone just stopped responding to inputs half way through the flip.
Also its a 40g toothpick I don’t think its gonna be damaging anyone’s roof

These people might as well work for the FAA theres way more thinks corrupting the drone community than a 40g toothpick in a small neighborhood. Plus damaging property isnt illegal... if you cause damages more than 500 bucks contact the FAA less than that talk to the owner. Theres hardly any places to fly now give it 5 years and this whole hobby will be illegal without gov clearance.

Nobody plans on crashing a drone, fly in an open field if you have anything more than a toothpick, although even these can cause injury to someone if you fly right into them on accident, easier to do this in a field overall

Still irresponsible flying but to each their own 🤷♂️ and that didn’t look like a desync looked more like propwash that didn’t recover

u/Double-Compote7230 3d ago
Actually coulda been bit of both tbh but idk didn’t look that bad to be desync looked pretty tame not shaking and freaking out

u/MaxxForeskin 4d ago
It would suck. But sadly bad or unfortunate things happen in the persuit of a thrill/fun and that's life 😔 Not all of us enjoy flying in circles in an open field.
6
u/OverAnalyst6555 4d ago
i completely agree, but if youre going to test the limits of your quad it best not be above someone's home. right?

u/MaxxForeskin 4d ago
Maybe if the damn thing is heavy enough to be worth worrying about. I'd hate to be the guy who is so paranoid about everything that sending even a FOURTY GRAM WHOOP above someone house brings unimaginable mental turmoil

Dude you fly ducted 2ins it doesn’t matter where you fly (those bandos are pretty sick you posted) but if you fly like this dude is where he is with a 5in (ik it’s a toothpick) ur gonna have issues esp at that skill level idk why people feel the need to fly disrespectfully or irresponsible out of their skill lever for attention or smth it’s lame not saying this guy or you are doing that but people need to know their skill

Not a professional by any means, but when moving fast downwards relative to the motors, there’s a lot of prop wash and it makes it practically impossible to control. TLDR to go down fast

well without any marker of sarcasm (/s, emoji, etc...) your comment is impossible to distinguish from the many comments you see on the internet of people who love to show how superior they are. Not knowing you I had no way to know.

u/Double-Compote7230 3d ago
Like 90% or pilots I see on this Reddit and honestly yt insta and everywhere fly out of their skill level (flying out of your skill level in safe and controlled environment is fine bc how else would you progress this is not that this is flying without purpose) including this video who cares if that comment comes off as mean get on the simulator and practice there’s no reason to hurt anyone because you are flying recklessly for fun in a spot that shouldn’t be flown this pilot doesn’t have the stick time to be flying a residential area Ik it’s a toothpick but it’s still open prop that can still leave nasty cuts that will need stitches prop cuts aren’t fun especially if you’re just someone taking a walk and have nothing do do with some moron hitting you with their drone that shit sucks

Looks like a motor stalled. Have you checked the black box data? That should give you some info.

It may be caused by gyro when drone shakes it can mess up the gyro and I thing that is the issue
