motors keep spinning after throttle is at zero (off)

[billybutcher]

hi guys,

wonder if i could ask for some advice please....

currently whilst landing my quad and keeping the throttle firmly down the motors keep spinning for a good 10 seconds, definitely two of the motors are doing this if not three.

using Apm flight controller, afro 30amp speed controllers and turnighy 935 motors. i have recently replaced a speed controller and motor and calibrated the controller in order to get it working

i could do with some suggestion as to why this is happening, any help will be great appreciated.

cheers

What flight control software do you use

Hi Taylor,

Mission planner, I have just re calibrated the esc and seems to be much better although haven't flown it yet but the throttle is acting more responsive. Still up for anything else that might help?

Cheers Billy

It's good that it's better, did you calibrate them in mission planner or with your radio?

 

[billybutcher]

with my radio, although i struggled to do them individually so calibrate altogether.

I think doingthem all together is best anyway. I've never done it with my radio, I always do it in librepilot

 

[billybutcher]

haven't heard of librepilot, is it similar to mission planner or specific for calibration?

haven't heard of librepilot,

Not applicable for you.
