Rcpilet....you're a Man after our hearts out here in the speed crowd.
I ran-in this plane in the same day as well....a little OS .40 FX in a Q-500,
A 9-6 MAS toothpick prop....over 16,000 as well. Both engines rated at
16K.....I wanna see 16K on the tach.
The other day I said a 12-6 APC would "dog down" any .60 engine, I took
some heat for it....

....wanna "dog down" a .46 ? Put a 10-6 APC on it.
These days....when Guys are trying to make airplanes into helicopters, the
props they recommend are odd IMO. I got into it with a Guy about the OS
1.08 FSR here awhile back....he thought it was cool to run it at 9500, tops.
I like to run 'em at 12,500-13,000 if possible....they rate at 16K.
Today, these Guys run the biggest prop that will possibly fit on the plane. [X(]
....don't ask me....[sm=stupid.gif]
