The Hobby People "Dragon Lady" is a good symmetrically airfoiled model and it should accept your DLE 20cc engine just fine.

OK, Beating my head again, Here is another one that is no longer available. It's getting frustrating, all kinds of GOOD suggestions and every one of them tends to be discontinued.

Ireally like the looks of the Ultra Stick, but not available, same for 4* 60 and 120. Of course the only one that is avaiable is the big stick, which to me is big stink. Idont like the looks of it.
What about something like the GPEscapade? It can take a 1.20 or 20 CC.
