Post your pitch PID’s here, but also check for small amounts of slop in the elevator pushrod and connections. Are you launching under full power? What plane?
hi JMan,
The most likely explanation is that your pitch P gain is too low. In normal flight the I gain will tend to even up the flight, so it will seem to be OK, but during takeoff things are a lot more dynamic and it can oscillate.
If you haven’t run AUTOTUNE yet then please do so.
Also, when asking why a particular behavior happens, please post a log file. Otherwise I’m just guessing the answer.
Cheers, Tridge
I used someone else’s files when I set it up as he had put a lot of work into tuning the PID’s, however, for my setup I think I have to tune my own.
I flew in acro mode today to see how it handled, and it was terrible. It was flying better in manual mode than in acro mode. I think the PID’s are off.
Next time I get a calm day I will go and use the auto tune and tune from there.
I am also waiting for a cable to hook up my 3DR radio’s so I can tune while in the air.
