I know nothing!
Don't stress it. I took @sundown57's design out last week and tried to fly. Even though everything tested good, I had nothing but stutter. Fast forward. I'm still troubleshooting and have no clue. Everything seems good. Wiggle it this way, and it all works. Try to tie it up and make it flyable, and yep. Stutter.Ok I thought I was almost ready to maiden and then some gremlins came in and f@#*ed things around. I was doing a little vertical thrust test and then went to try the control surfaces, all was good until I tried the ailerons and all went bizerk, everything going nuts . Looked at the rx and light is flashing widley, not touching anything in a few seconds everything calmed down light went solid and surfaces centered . Tried rudder and elevator a bunch of times and nothing, just barely move the ailerons and all goes nuts again. Then for what ever reason lets do a thrust test again and within 5 seconds the motor slowed down to 25% , now what the heck? Put the battery back on the charger and it still had 12 volts so what gives. Tried programming the ailerons to channel 6 just to see if any different and that's a big nope, same nutso crap went on. So now I tried a different rx, same crap again along with the motor slowing down within a couple seconds and test the voltage and it is good. So concentrating on that I plug the voltage tester into the balance plug and then fired up the motor, cell 3 dropped to 4 volts almost instantly , shut the motor off and within 3 seconds it is back up to the same voltage as the other guys so a bad battery . Had that happen before where a cell would drop off instantly and then within a few seconds it would show good. So one issue solved, thought maybe the Y connector was causing issues so pull all the wiring apart and start testing individual servos. Found that one or two separate and even a tiny bit of a third one you were almost ok and was harder to make it act up but 2 servos on one circuit drawing fuel juice set it off instantly. NEW esc time, the bec can barely run 2 servos on separate channels and the rx at the same time. Now my glitch is all my servos laying around are 40A and up and I am down to one 1300 3S battery . Just really ticked off right now.
I still haven't found the cause. I'm going flying tomorrow, I hope. I REALLY wanted to put his bird in the air. I owe it to him. I still haven't figured out the problem, though.
