RE: TT Pro 120
I'm flying the TT120RP (rear exhaust w/ pump) on a Excelleron 90 from Hobby People. It is truly unlimited power for this plane. It has a 66" WS and weighs about 8# rtf. You can check the Excelleron 90 thread in the pattern forum for alot more info on the plane. I got mine for $200 on sale.
