OK, I don't know how fast is fast! If I had to guess I would say my head is around 1900 RPM. Can someone poiunt out where I can find a highquality video with good sound of a heli flying with a certain headspeed? Perferably a Raptor 50 but I think about any heli will do as I am completely in the dark and can't afford a governer or a tach after splurging on my pipe, gyro, and digtal servos.
