I have set my thr_min at 165 mid at 400 and max at 800
After arming the props seems to spin correctly at about 165. If I then raise throttle off zero nothing happens until about 30% when it suddenly shoots up into the air. (Except this is a bench test so the frame pulls upwards suddenly in its harness)
What can I change to get it to be a bit calmer spinning up?
Thanks for any advice.
