    Best prop for OS FS120 Surpass?

    I just finished breaking in my OS FS120 Surpass with a 16X6 prop. Which prop would you guys recommend for the most speed? Its installed on a ModelTech Dragon Lady which slow downs and floats for landing, so I am thinking of a 16x8 or so.

    Thanks
    Best regards,

    On my OS120FS I had a 16x6 on my previous Extra, on my current Revolver, with same engine, I use a 15x8 for a bit more speed. Both are perfect for this engine.

    Thanks. I did the break in with the MA 16x6 and left it there, but I will try the MA 15x8 after a gallon or so.

    Hi!
    The Master A is no good! Much better is a RAM or Graupner "sonic"...or APC. 16x6 or 15x8!
    14x8 is way too small!

    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

    RE: Best prop for OS FS120 Surpass?

    Hey Warbird, around 20 years ago I was running an APC 14/12 on mine. It was in my CG Ultimate biplane and it handled it just fine. Was fast for a biplane and still had unlimited vertical. I'm still running the same engine now in my Wildstick with an APC 16.5/5.5. I tried a 15/8 and a 16/6 but with both props it seemed to over rev and knock at full throttle. This engine likes to be loaded, so for better hovering I think I'll try a 17/5 next.
