This question gets asked alot.......maybe this forum needs a sticky for viable pattern arfs organized by size...there are a quite a few of them.

I'll start with the Excelleron.....both sizes.
Leo
Swallow
Quest
........so many of these fly really well......it's best to get something in the air, get the airplane trimmed really well (get help if necessary), and burn lots of fuel.

Good luck and enjoy the pattern community.
