Joey,
For a cheap quick fix for your quickie, try a Mac's tuned muffler. I have my Predator set up with the 46Fx, Mac's muffler, and Master Airscrew 9X8. [ I know, their are better props, but our paved runway eats APCs for lunch.]
In fact, I'm thinking about clipping off about 4 to 5 inches off of each wingtip, and using a 32sx with a Mac's . This is a hot little 'sport' motor, and the reduced weight and wing area should make this as quick as the 46fx......Any thoughts guys???
[I'm just using this plane for fun, not racing so am not concerned about not meeting quickie regs.]
