| Stuck in idle
I was flying my T-rex 450SA and landed and changed the battery I flew for about two minutes and landed.When I went to take off again the heli would only idle.It starts to spool up then slows down then starts to spool up then slows down,thats all it does now.I noticed when I plug the battery in it doesn't make the confirmation sounds any more.All servos are working properly,it just won't spool up to rpm.
