DJ,

a few folks have said that the stock AA props put out quite a bit of power with the 7mm motors (especially with the blue/purple endbell motors, they like higher RPMs, and the smaller AA prop will certainly give it to them). but, if you're wanting to go to a larger prop, try a GWS 2.5x0.8 or GWS 2.5x1. both those props are good matches for the 7mm's. the only draw back from going to a differant prop is that they're not counter rotating, but it shouldnt pose much of a problem.
