where are guy's getting your 4 blade prop's? Just looks too cool not to have one. Also question, I have 2 engine possibilities for my top flite .60 build coming up here shortly. Well 3 really, I have a new in box st .75, a new in box asp 108 red head, and a magnum 1.20 4 stroker. Any thoughts on which I should use. Need to start making some decisions before I embark on my first scale build. Phil
