Hughes H1 racer engine quits - need help for settings


doering1

Recommended Posts

Just purchased the Hughes racer. No matter what throttle, mixture, prop settings I use the engine quits and blows black smoke after about 1-2 minutes of flight. Airspeed is only around 150 mph and not pushing the aircraft. Some engine setting is not right. Help appreciated to get this plane flying at high speeds.

Not just RPM, for that is normally PROP RPM, not ENGINE RPM. Usually Manifold Pressure is a better indicator to watch. The higher you have it, the harder the engine works. Watch your Cylinder Head Temperature, as it indicates the heat the engine is generating internally. If it's too high, either your mixture is too lean, speed to slow, cowling flaps closed, or any combination of the above.

Just a couple thoughts...

Had a thought...then there was the smell of something burning, and sparks, and then a big fire, and then the lights went out! I guess I better not do that again!

Okay thanks, I'll pay attention to the other parameters also. Just want to get some flight time in for now. Can't seem to find the spot to untick "engine damage"
