Do you guys think these newer Sensenitch/ whirlwind GAP propellors are as good as say the Catto/prince designs.
Also, if I didnt care about climb would reducing diameter and increasing pitch yield any speed gains? I always read that more diameter is better but its also harder to turn that more diameter. Im running out of areas of airframe cleanup and starting to look at the prop as the last move. Contemplating having my sensenitch GAP cut down in diameter.
Plane is ZodiacHDS/ subaru E81 100 h.p.. 70" Sensenitch 2 blade. Also have 68" warpdrive 3 blade. Sensenitch is 3mph faster but louder and vibrates more. Thx Jeff
