I just reinstalled all the electronics into my shell. I've replaced a shell before. Now instead of the usual little musical tone I get a steady beep...beep....beeb..... and a red warning light under the bird on the right side near the battery compartment. (facing away, battery towards me). I've checked all the wiring and everything seems to be in place. The only unsoldering I did was the red and black to the battery holder. Unhooked the normal harnasses but pretty much took out the ESC and motors still soldered. My camera and servo control are disconnected but that's never cause a problem before. Any ideas. I was hoping to try to fly today to check out my attempt to straighten an arm.
