Suptter.....
....let's face it, sometimes a dealer will push
something off on a guy, just to get rid of it.
Odd-ball stuff, or over stocks, ect.
But in the real world....you can get a dozen
prop recomendations from a dozen guys. It all
boils down to what actually works for your
particular plane. The engine size, RPM range,
the weight, size, and aerodynamics of the
plane....is what's gonna determine what prop
actually works best for your plane, at your
field.
Prop recommendations are good, for a starting
point however. If you have the instructions that
came with the motor, use those. Start out with
the choice of the smaller of the recommended
props. Allow the engine to rev freely, and not
overheat. The engine will break-in faster also.
Once it is broken in....nice clean oil on the plane,
not the black gook....you can prop it up a bit and
see what it will pull.
The 11-7 1/2 MAS is the best all around prop for
any .60. Later you might try the the 11-8. Some
will pull 'em, some won't. Then try a 12-6, or a
12-7 Zinger. Same thing....it might not like the
12-7.
I take back what I said about the 12-8 Zinger.
Your motor won't pull it, it may not even like the
12-7.
