This is my firts APM project.
I assmebled the quadcopter, upload last firmware, calibrate everything (escs, compass, radio) and get succes to arm it on my workbench.
Baterry and USB connected, lights blink red and blue alternating, them get the sinble blinking red led.
Try to arm and motors start and accelerate by radio command.
So, turn everything off, installed propellers and connected it for a firts flight.
Now, the blink red and blue alternating, but get a two blink red light, what means startup problems.
Connected to MP again, and work fine.
Has anyone experienced the same problem?
