My quad wobble descending and changing direction

Post by afaf »

I'm still try to get the perfect PID settings. BTW now my quadcopter after a lot of trial/error it's quite stable.
If it goes up, wind moves my quadcopter. If I try to compensate wind effect, my quad wobble a lot, the same goes when i put throttle a little down to make it descescending.

Fast movement when it is not high/there's no wind, doesn't produce wobbles, apparently.

Can I improve this?

Re: My quad wobble descending and on wind

The same goes when I put full pitch stick forward and then (in order to stop quadcopter) i put it full back.
It wobbles a lot.

Any advice?

is it a fast wobble or a slow wobble? im not an expert by far, but this sounds like a PID problem.

sure. Have a look at the compilation of PID tuning info you collected & started to publish for others to use and enhance. Ah, you did not do that, you just keep asking questions. Too bad.
