I was flying it the other day and all of a sudden it became uncontrolable.This heli has never had any major crashes.I went through it top too bottom,nothing broke or bent. The one add thing that I did see is that when arming up the 4 in 1 I use to hear the 4in1 arming up and see the servos set.Now I dont hear or see the servos setting.I am starting to think that the 4in 1 is toast.I plug in the batterythe 4in1 flashes red a few times then to green. Is there a way to test the 4in 1?
Thanks Rich
