My Avistar (hobbico) will do the usual trainer stuff pretty well - loops/rolls/cuban 8's - will fly inverted pretty well without totally pushing the stick all the way forward. Will snap roll if you really try hard or find it by accident....

I gap sealed my ailerons and on max deflection it rolls pretty nice for a trainer type plane - probably till the wing splits down the middle that is.

Guy at the club has one he put together totally stock other than he elminated a lot of the dihedral and it seems to make a pretty nice fun fly type plane so far...
