Help!

Kotleta 20 ESCs don't work well


Hi,

I'm using CUAV V5 and Kotleta 20 ESCs with DJI 2212/920 KV motors. When I try to takeoff, the quadrotor vibrates like a jelly. I set a few parameters via developer port, but nothing has changed. Here is video link:

. Here is screenshot of developer port.

Ohhh wow. Thats very bad. Sorry you are not enjoying flying.

1. PID. Looks like too high D. And possibly too high I. A good safe start is P20, I10, D10. P/D ratio is first to tune. Typically 1.4. But can be even 0.9. Higher is safer, and will create very fast wobbles.
2. Filters. Make sure you have dterm filtering.
3. Bent motor shaft/prop balance.

Acro and Altitude modes are good


Hi,

Thank you. I tried to work with other modes like acro and altitude modes, and there was not any vibration. I setup default parameters when I try. When I use other normal ESCs, the vehicle did not vibrate and tookoff safely. I could not understand.
