[:-]I've Got this engine on Carl Goldberg 67" YAK 54. Flew a few Flights with APC 17 X 6 Prop. Going Try APC 16 X 7 or 16 X 8 see if I get Unlimited Vertical and faster engine spoil up. Engine has Great Power and I Just Need Dial in the Prop for this Airplane. Did You do any Thrust measurement? What Airframe You Flying it on? I haven't Tached Mine since it had Great Thrust on the Ground. Climbing Straight Up is where see how well that Prop Pulls and also Hovering and pulling out Hover.

The engine lives in a BUSA 1/4 scale Fokker Dr1 that weights 15 Lbs. It flys very well with a TF 18-6 prop. A MAS 17-8 scimitar did OK but the 18-6 seems to fly better. Have not done thrust testing.
I have played with a Performance Calculater on line that says a 18" prop at 6900 it good for about 13Lbs thrust.
