Funtana 90 for $209.

Heck, the stock muffler will rotate 90 deg to act as a Pitts, and looks like will fit in the generous cowl of the Funtana 90.

TT 120's weight will balance the Funtana 90 perfect. Use APC 17x6 prop to get 16 lb of thrust. Plane will come out a little over 9 lb. Normal 120 size ARF's will weight over 11 lb, which will not perform EXTREME-ly well w/ 16 lb of thrust.

Another good choice is Extreme Flight Yak. But it's not in the same price range.
