I'll stick my lil toe in ...

I KNOW that you said "low wing" - got that 'cause I can read

You asked for something that will fly "on rails and can fly aero". Well, what if ya raise the wing a bit? My 1st and 3rd builds were 4Star60s and my 2nd and 4th were SIG Somethin' Extra's (mid wing). On rails? 4Star - not so much. Somethin' Extra - oh yea!!!

The SSE (SIG Somethin' Extra) is a very popular 40-sized kit - easy to build great fun to fly. Check out the threads - there's plenty of them.

Just sayin' ...
