can any one save me from insanity! I am new to helis,just got my first one, it's a T-rex 450 XL second hand.I have spent the last 5 days reading everything I can about setup of the heli & how to set up my new DX6i tx & AR 6200 rx. All was fine, everything was working as it should, Changed the battery & all of a sudden the elevator is working in reverse ! & rx light is flashing. did the bind again but still the same. after checking everything 100 times I find one of the batterys when on my new TP-610C Thunder Power RC charger come up wrong polarity. The colours when connected are right from battery to charger & this battery was conected to my heli just before the problems started,the wires on this battery don't look like they have been tampered with. I'm lost!!!!!

Reversed polarity would explain the control reversals as well, sounds like a dodgy battery.

I assume the battery is second hand as well, if not take it back and get it checked.
