I have a quad with a clone apm that quickly raises and lowers the throttle while desending. Does anyone know which parameter I can try changing to smooth out the desent?
The problem you have wont be fixed with a parameter. The reason why its jumpy is because the baro sensor is getting a bad reading. Make sure you protect it with a piece of foam or shield the flightcontroller from the propwash.
Hi and thank you for the reply. I'm watching my altitude readout on mission planner, and it is very steady.
You might try reducing this one:
Throttle acceleration controller P gain (ArduCopter:ACCEL_Z_P) Converts the difference between desired vertical acceleration and actual acceleration into a motor output
Thank you very much for the responses, I will try.
