Heli Engine Probs
I have just traded for my first nitro heil, a Century Hawk Sport, and I was hovering it around the back yard and it does ok for a minute, and then the engine and rotor slows and sinks back to earth. Do I need to tune the engine better? How do you suggest I go about that? or Do I need to take some pitch out of the rotor and let it spool up faster with the higher RPM?
