Ok that was a good idea. I removed the main and tail blades and spooled it up in idle up 100% throttle. all servos were working at first. Then i twisted the heli back and forth in my hand to excersise the 3 axis gyro a bit and bam, no more rudder servo control. I did some more flipping the heli around in my hand and i lost the elevator servo control as well.. various cyclic servos were drifting in and out of letting me control them or not. The tail servo was dead the entire time.
Next I spun the tail servo gears by hand to see if they would kick in like the servo was stuck or something but nothing. I spooled all the way down and still no rudder servo control, then all the sudden the servo motor kicked back in and I could control it.
It must be the 3 in 1....?
