just had my first crash, heli was only 2 feet off the floor so it didnt come down too hard.
problem now is thst when i start to give it throttle its startes ok but as it starts to get fasterthe power stop and starts for a couple of times and then wont spin at all. if i turn it all off and back on again it does the same thing everytime. is it possible that this is a fault in the esc or the receiver?

Im only a beginner myself so take my ideas with a pinch of salt

But if it was a little drop maybe the crystals on the heli have come loose, try pushing them firmly into 3 in 1 it could be as easy as that
