From what I hear, the Sig 4 Star .60 is a great second plane...and if you extend the rudder and elevators about 1 inch, it is capable of some 3D maneuvers. The Somethin' Extra is a decent second plane also, but definitely touchier. Both can be made to do all but the most advanced maneuvers. I think the kit form of either plane can be had for between $70.00 and $80.00 (not the ARF versions). Both these are a little larger than the Uproar, also.
