My quadcopter first flight, with APM 2,5 ardupilot and rctimer components.
Unfortunately the second flight was not as funny as the first one.
After about 2-3 minutes of fligth the copper went down directly into a small river.
Three ESC are broken and a lot of N-Mosfet where blown up. The cause is under investigation but at the moment I've no idea on how to prevent the problem.
The ESC's were flashed with a SimonK firmware, I'm not sure that this could be the problem.
So I had to buy four new ESC from another shop and of different type.
Back soon here with flights with the new configuration, "The show must go on"
