Need suggestions for selection of prop size
I would appreciate suggestions for selection of a prop size for a warbird. Engine is a 1.20 Surpass 4-stroke. Wingspan is 84", 1040 sq. inches, 11 lbs total weight. Balanced using only a Higley brass prop nut. I am currently using a 15X8 Master Airscrew with just so, so results. Plane gets off ok but seems to lack speed/gusto once airborn so I am reluctant to get into any aerobatics.
Thanks
Jim Biza

Tower Hobbies has several models of the Surpass listed and they all call for the 15 X 8 prop as a manuf. sugg.
I did find out that the MA props don't have the performance of an APC of the same size. It made a world of difference on my G-38 when I changed to APC props.
BTW, I've got two MA 18 X 8 props if someone needs them. I won't use them any more.
