I have a dumb question. WHat are the odds that they will just send me the 3 n 1 board with proof of purchase, without me having to send them my heli. The problem is so intermitent, if they get it and everything looks OK and the test fly it and it works good, they'll just send it back AS IS I suppose. Kind of a weird situation. I am gonna check the solder joint at the connector. Thanks for the info.
