It sounds like you're already an accomplished 3D pilot. If you were just starting, I'd say go with a TufFlight 4D. I think your 63 would go really nice on a Sledge, or perhaps one of the lighter ARFs if you keep it at or under 4.5 lbs.

Regarding profiles being great for 3D, I think they do have much better rudder authority, and are THE BEST "40 size" 3D planes around. Non profile planes tend to have very little side area, and don't set up well for high alpha KE moves.

From what I've seen, attempts to make pattern planes (non profile, or box fuse) that do good 3D end up being heavy, and 40 size engines won't power them anymore for good 3D performance. So there really isn't any such thing as a good pattern 3D performer with a 40 size engine. Prime example " Funtana 40 size. Can you really 3D one with a 2 stroke 46? No. Even a 60 or 70 size four stroke isn't enough, so guys end up going with something bigger, and they get a 5.5 lb "40 size 3D plane".

If I've missed a glaring example, please let me know, but also, please list the weight and loading specs.

I'll take a 4.5 lb 750 sq inch wing profile over a 5.5 lb 600 sq in pattern "3D" plane any day.
