Richard the 15x6 seemed to be perfect for the break in, I don't get all carried away with heat cycling and all that. There is nothing in a Saito that can benefit from it. I just do what I do to get 40 some minutes on it and they're ready to go. It doesn't take hours or gallons of fuel. I have never worked out a way to measure thrust. I should toy with that idea though, the longer prop would look better on the AT6.
AC, do you have picture of the Evolution prop and is it from Horizon? Thanks, Dave
I have the new 1.25 in the PSP ready to go with a new MA Classic 16x6 on it. I also have an old Graupner 15x8 to try also.
