A1programmer it all depends on your price range my friend.
Is that .65 or so going in a 60 sized aerobatice plance? Depending on your experience, you might want to venture into the 4 stroke arena with a saito 100 or ys110 (these engines will fly a 60 size plane with MUCH authority). Price - around $300 give or take some change. Or maybe a more moderately priced magnum 80 for somewhere in the $160's.
What size is the smaller FAST plane? I'm thinking that if you want to burn holes in the sky and your wallet, you should head over to

Hope this helps...
