Default Whats a good speed prop for this plane???

I have a cosmic wind with a th .75, I had problems with the motor now i have it runing great. I have a 13x7 MAS on it to keep the revs down till i felt i knew how to handle it. I now now that it handles great. I made some WOT passes with it today an i figure it was somewhere in the 90 to 100 mph range. I now it can do more. what would be a good speed prop be for a almost 8 pound, clean lined airplane?

Hate to say it but you're not going to get much more from it, going to an APC 13X7 or 12X7 might get you a couple mph, but you're not going to get much more...

In the Bobcat thread a 11x8 is one of the props used on that engine with good results. I would try that before changing to a larger engine.

The Bobcat is over 5 lbs. plus it would only take 13,500 rpm to have 8 lbs. of thrust with an eleven inch prop. I do not own a TH 75 but I understand they are strong engines. I think it may be a good match.
