alright guys.. i'm beyond frustrated and hoping some experianced members could help me out.
I just killed my 3rd CC3D on the same Frame, and I can't figure out how or why. and it's all very random.
1st death: I'd flown maybe 10-15 flights w/ it. been through 2-3 hard crashes, and then it stopped working. I assumed it was crash related and ordered a new one.
2nd death: had maybe 5 flights. took the quad inside to tune PID. it connected and allowed me to tune PID with no issue. returned outside, and the quad wouldn't Arm.. took it back inside, checked my arming settings (it connected to PC no problem). Then outside again, with same result; it wouldn't arm. Back inside, this time PC wouldn't recognize the FC. No blue light on the FC only a green power light, but PC/Librepilot would not connect the board, regardless of what trick I tried to rescue/reload the board. So i sent it back as defective and got a new one.
3rd death: just recently re-installed the new FC, loaded it up no problem. did functions check, all worked fine. Took the Quad outside, went through 4 batteries (back to back). Took it inside to let batteries charge. this time I connected a LED controller to the PDB 12v rail, and then a signal wire to the aux output of the FC. still worked. Connected to Librepilot to configure my Aux setting. unhooked from computer and set up my gear on the Tx. wouldn't work. reconnected to PC and now a dead FC.. no green light this time.
I can find nothing 'obvious' behind any of these 3 scenarios. I've looked for shorts in the wiring. I ahve a 12v feed comming from the PDB to the 6th channel of the FC for power, that is getting 11.6v. The FC is mounted on nylon offsets w/ nylon screws holding it to the frame.
any thoughts?
