Are you doing this with props on or off?
With props off, no problem when I quickly switch up/down throttle
Could you help please ?
The problem is not solved
Reading this might help

I have to disable Low RPM Power Protect ?
I would like to try :
Demag Compensation = OFF
- Low RPM Power Protect = OFF
- Startup Power = 1
- Timing Medium High
But I’m afraid of burn something… Could you give your opinion please ?
I have tried
Demag Compensation = Low
Low RPM Power Protect = On
Startup Power = 1
Timing Medium High
The problem is worst
Should I try
Demag Compensation = Off
Low RPM Power Protect = Off
Startup Power = 1
Timing Medium
PWM Frequency High
?
Video of the problem :
Like I’ve told in RCG, this type of bench testing it totally worthless and a supreme waste of time and effort. Put some props on it and go fly it…
I have made a test with props, motors seems to produce a strange noise at stop (a little bit covered by pixhawk disarming beep, listen carefully).
Motor timing problem ?
… ?
Oldgazer is right. Get it off the bench and fly it. Default BLHeli setting should work. The only change you may have to make is to turn off low RPM power protect but usually only on motors with a lower kV than yours. On some 380kV motors I have I had to turn it off.
The noise at motors stop is strange and I would like to fix it before fly
it to crash it…
Ok this sounds fine off the video BTW you could have breaking installed that’s not necessarily bad. .
Thanks for reply, break is off
I heard nothing wrong with the motors. Go fly it.
Before fly I have a question : with my others pixhawk I have calibrated the accelerometer before put pixhawk on drone, but not with this drone. I think that the calibration is accurate (I hope) but less accurate that with my other drones, its very important for stability… ?
Yes.
Get a spirit level and a deck of playing cards. Put the air craft on your workbench and check it for level. Shim the landing gear/feet with playing cards until the frame/Pixhawk is level fore and aft and side to side. Calibrate the accelerometers.
How can I calibrate sides and back… ?
You pick it up and follow the voice instructions…
If I save full parameter list to file, its save calibration data… ?
It saves everything.
