RE: Best prop for OS FS120 Surpass?
I have a 16x8 MAS on a CG Ultimate, a 15x8 MAS on a Yak-54. Both are not real fast, but seem to be propped just right for those planes, providing fairly constant speed in all attitudes. I think for speed I would go down in diameter an inch and up in pitch by one or two or more, and also go to APC props. Dunno for sure, just guessing. Jon
