I'm new at this, so forgive me if I'm on the wrong part.
I have a brandnew Pixhawk on my quadcopter (previous with a Cruis aiop v1.1 board)
On the Crius I had no trouble with the EMAX 4in1, but now I only thing I get the ESC's in the "programming mode".
This is what I do (found it on the net, but it's a no go for me)
Turn on TX (Frsky Taranis) give full throttle.
Connect PixHawk to USB.
Press safety button (constant red light)
Connect fly battery.
The 4 motors sound like in program mode (1,2,3.....1,2,3 etc)
It does'nt matter if I press the safety button or not.
I hope someone can help me.
