I've looked at the Kyosho manual and their airplane is a little bigger (7" on the wings). One of my biggest concerns of course is CG. I've flown for a while now and this will be my first step into the racer category. Thanks for posting the link to that Kelly thread! I'm learning a lot there. It seems to me that speed is directly linked to wallet/pocket depth. I may end up simply running an Italian ST 45 due to this aircraft's smaller size
