After the change to the Sony CX730 my whole setup seemed to be wrong due to the extra weight. The 12x45 props generated a lot of vibrations, the motors almost run up to 1950 microsecs. I checked the balance of the props 3 times and the static was good. But I can not balance dynamically. The 6 new MK props 12x45 did part of the trick. They diveded the vibrations by a factor of THREE (ACC went from +- 1.5 to +- 0.5). But also the mots MS2216 900 showed some vibs and bearing play. Furthermore my flighttime was to short with 6000 3s and the MS2216 not powerful enough to carry more Amps.
I never got over the thought, that the MS2216 have not enough torque to follow the attitude commands but that is just a wild guess.
I decided to opt for MN3508 700 @ 4s.
Here are the first pics of the new mounts and some other parts.
