Throttle dampening issue - Pixhawk

Hi All,

I anticipate that one of you fine folks will be able to point me in the right direction!

I’ve built a lovely new drone …

Problem:

  • Motors only spin up to approximately 15-20% of max
  • Any movement of the throttle above 20% seems to have no effect

Other information:

  • Setup is an F550 Hex, Pixhawk with 3.1, T-Motor S25A 600Hz Opto ESCs, MN3508 380KV motors, 15x5 props, Aerialmob arms
  • Radio calibration looks OK. signal moves from 993 up to 1997
  • Motors seem to respond correctly across the full range of throttle inputs when in ESC calibration mode

I think that I managed to enabled motor logging and I have a log attached. I’ve been on the Naza train, and am new to APM/Pixhawk

Thanks heaps for any tips as to what I should look at!

I will mark this as solved.

I read something about a Min Throttle previously so went searching for a Max Throttle parameter. I found it by clicking Advanced menu view in the standard params screen.

I have not idea how it happened, but MAX_THR was turned right down.

Anyway, problem solved. I’ve set MAX_THR to 1000.
