FYI this was a problem for me, as well as a lot of other unusual behavior, before I realized that the white crusties on the underside of the board were causing trouble. Cleaning the underside of the board and making sure it was suspended above my quad seems to resolved the issue for me. No more signal issues, not counting me forgetting to turn on the Tx or plugging everything in backwards.
