The mini quad is back in action!
I was having some strange problems with my ZMR 250 mini quad at the start of the summer. One motor kept out during flight, there was also some strange pitching behaviour during aggressive manoeuvres. A lack of time to do anything over the summer meant that it was mothballed.
I had a couple of spare hours this week whilst avoiding the last episode of Downton Abbey to take a look at the problems. It appeared that one motor had a short. Testing the resistance between the motor leads and the stator found the short. A quick motor swap and solder job and it’s back in flying condition again so I’ll be getting some FPV in again when the winds calm down.
