Default RE: St 90 break in today


ORIGINAL: Cyclic Hardover

You wasted a whole gallon of fuel on break in? Why? I spend a couple tank fulls "properly" adjusting my engines and then fly it. Everything else is a waste of fuel and flight time. A person can run 5 gallons through and engine but if its not properly dialed in, whats the point of it. All that waste of time and fuel is not going to make it run any better.

Were he running an ABC engine, I would agree with you, but he is not. He is running a ringed engine.

This is one area where helicopter experience will shoot you in the foot. Airplane engines do not run grossly rich in normal operation as helicopter engines do because of lots of nitro at a screaming rpm.

He did it just right as far as I'm concerned. Now he doesn't have to worry about how the engine will turn out. Of course, the engine isn't fully broken-in as yet, but it is close enough to fly-in the rest of the way.
