OS 160 FX ???

[vicenterc at comcast.net]

I flew the same set up using 17x10N APC prop on a DP Extra.  I was getting 
around 8250 rpm.  I tried 17x12 and was too much load for the engine.  I have 
only one problem flew trough the sun and lost the plane.  I agree likes to run 
rich. Don't try to adjust for peak RPM on ground and fly.  You need to open at 
least 1/4 of the turn from peak on ground if you don't use a pump.  I think the 
17x10W could be better but never had chance to try.  I used 20% nitro.
