Not sure what the problem is. you mention it being cold??? HUh I would call helimax if I were you. They will tell you to send it in. But if you talk to the tech a bit they will send you the part and you can replace it yourself. They sent me a new 3-1 board. sounds like you might need one too. I dought the LHS will be able to make much of a difference, since the warrentee is through hobbico.. Best suggestion I have is call Helimax they are pretty cool.

Good Luck.
