I flew my Raptor 46 with the stock woodies for a couple of gallons at least, at that point a put a long boom and 600 blades to help keep from over speeding the head. Anyway with the stock woodies the Raptor was able to roll, loop, 4 point roll, tumble and they autoed reasonably well. My vote is to stick with the woodies for a bit, if you realy feal you want the better blades, I like my model sports very well.
