Hello I need help with this I have searched and searched but cannot figure it out. I have a P3A that I have swapped out the main mother board, shell and replaced with a new gimbal after a crash. I also replaced ribbon cables and anything that looked damaged. When I power on the a/c I get the welcome chime ( the four loud beeps) but I do not get any wing leds or gimbal movement. The led on the gimbal does not light up At all. I cannot link to my controller either. Anyway I am looking for any pointers to get this aircraft back in the skies!
