Thanks for the input mate! I have come to a similar conclusion about prop size. I have ordered a 16 x 14 Bolly. With any luck it will be available this weekend. I have the custom Bisson muffler for it, which is a lot better than stock but not like a tuned pipe.

With regard to the CG, on its back it requires a little pressure on the elevator to keep it from droping its nose. However, moving the CG forward 1/4" shouldn't bother it too much and any snap improvement would be great.

Thanks again,
