    ""anyone got some number with 17x8""



    Magnum 180 4st; APC 17X8 burning Magnum 15%/ 8100 tuned for flight,,

    if you can get it I would sugest to move up to 10% or 15% (even 20%), I ran 5% for a few Tanks for the "Brake-In" and it runs much smoother on 10 and 15%..

    RE: ASP/MAGNUM 180FS readings

    wow RPM update

    Magnum 180 fs,, 1 Head Shim, Wild Cat 15% Nito, 16% oil, same APC 17x8w, 8850 RPM tuned for flight,,

    I have to say I was surprised to find this number after I removed one of the Head Shims,, but I also have to say that the APC 17x8w IS the wrong prop for tight acrobatics, it takes to long to Rev-up, I think an 18x6 or 18x7 quality wood Prop would pull much better around half throttle

    I'll let you know

    just curious i thought the 16x8 was the 150 prop of choice.... i guess as long as the rps are under 9500 its all good

    ""just curious i thought the 16x8 was the 150 prop of choice""

    Junkie,, first, this is a 180 not a 150,,

    2nd, the APC 17x8w is ok for acrobatics on the 180 when you don't need a quick Rev Up, I did some tight loops/almost a flip, but the Engine would not Rev Up quick enough to pull the plane up into another tight loop,, a lighter Wood Prop with a larger Diameter/Less Pitch would Rev high yet because of the larger Diameter it should pull more Thrust at half Throttle

    yet, for a War Bird the APC 17x8w would be better than the larger Prop with less Pitch..
