I'm flying a Raptor 50. Today I noticed some vibration in flight and a loss of power when I was hovering. I landed it a bit hard but no crash. On the ground I noticed that the engine runs fine, but the rotor is not turning like it should. It seemed to recover and I flew it once more and then the same thing happened. I can accelerate the engine, but this time the rotor did not turn at all. Is this an indication of the clutch going bad? This helo only has about 4 hours of flight time on it.

Any suggestions appreciated!

Pull the engine and check it out. Could be the clutch or lining. Just pull and check everything. It doesn't take long.

Make sure that your engine is not running backwards. You should feel a definite clockwise pull when you add throttle while holding the blades.

Experience is something you don't get until just after you need it!

Pinch off your fuel line while its idling. If it runs for more than 3 or 4 seconds before starting to speed up and die your low end mixture is too rich. They will kick and start running backwards.
