Since my phantom frame is all bent and beaten after several crashes, and it seems impossible to find a replacement, I decided to get a F450 frame, and move everything from the phantom. I'm now wondering if this is possible at all, after I completed the tasks of soldering and moving everything over, I got stuck with a Low-Volt  error. Checking the assitant software, I noticed that it can't actually read the battery voltage at all. To power up the naza, i simple soldered a servo cable to the power distribution board, and plugged it in X3. My question is, is there additional electronics on the Phantom board that's needed for this function to work? If so, this means you cant move to a new frame without buying a new Naza unit, which it seems has these extra stuff in the LED unit.
