We had this problem with a number of matrices. turns out the arms can twist off their 3 degrees or center positions, yes, they can twist despite the locking mechanism. its easy to fix, place a spirit level (a builders level, or use an app on your smartphone) on top of each propellor and if they are more than 3 degrees out, get a hex key, loosen the bolts holding the arm into the body, twist it back until its within a few degrees and try again. Its worth doing this service every few flights because even a tiny sideways landing can knock it out of shape.
And yes the problem is often only surfaces with weight and full throttle. |
