I have a mini Titan with the supplied motor and speed controller,I have had many flights,and many crashes. I can fly cautious circuits and figure eights and hover in all attitudes.
Occasionaly in the past ,a little more frequently recently, the power seems to pulse,the effect being you can hear the motor revving a little higher and the tail wagging a little side to side, about once or twice a second.
Increasing and then decreasing the throttle, to maintain altitude, seems to make this stop a short while but it invariably starts again, and then before you know it the power dies off and the helicopter plummets. I tend to stay low so this hasnt caused any major damage yet but the thing is, if I close the throttle and immediately take off again there is plenty of power left and can fly for another two or three minutes.
Has anyone else experienced this or got any ideas what might be causing this.
Batteries are 3S1P 2150 impulse 16C and Kong power 3S1P 2200 26C and always have been
