So as you guys here can see in the photos, my new mamba f405 Mk2 with the 40a matching ESC's and flight controller is not working. To elaborate on my current problem, when I plug in the battery there is a Green, White and feint red light on the Flight controller and I only get the first 3 beeps and not the last 2. So I know that the ESC's and motors still work but it is the FC. Then when I plug in the receiver the white and and feint red light go away and there is only a green one as the photo shows. So I am really discouraged as a beginner and though I would come to this forum for some help from you guys. Just as background I have crashed 2 times trying to fly. The first ripped out the bat wires but that wasn't an issue and I re-soldered it in an afternoon and after replacing the FC to ESC wires it was back up and running. The 2nd time was less serious as I crashed in soft dirt and nothing happened. I was back to flying right after. The next day I went to fly and this problem happened. So like I said I am really getting discouraged because I have no Idea what is the problem (I have tried like everything including flashing the firmware on betafligh). So I would really appreciate if you guys helped. Thanks and I hope to be flying soon!
