well, i have bad luck from beginning.
I crashed it few times (nothing too bad tho) and reason was cloned AMP Ardupilot.
Then, when i figured , that APM was cheap clone, i bought brand new Pixhawk. Must say, easy to install and worked out of the box.
I did save trim and auto tune. All end up great, so i decided to out on my retractable landing gear
Well, all looked well and worked on my working bench.
So, i took it for a spin and my second flight was disaster. When i lowered my retracts, multicopter lost control and crashed on the ground.
I couldn't believed, what it just happen. It was flying perfectly day ago. Then i realized, that crash was caused by retract servos. They draw so much current of my 5A BEC that APM board and Futaba receiver blackout.
here is my video from actual crash: http://youtu.be/1re5kn3h2nY
