RE: Lil Toni Engine Choice
I tried my plane with a Magnum .91 2c (12x8) and a Saito 100 (12x12). The Saito was faster. The conventional 2c like an OS, Magnum or ASP is just not timed to wrap up like a Jett.
The Saito spun the 12x12 at 10K (30% Nitro) on the ground and noticeably unloaded in the air. It would take off well and turn into the traffic pattern but as soon as you headed down wind it would unload and the revs would stay up for the rest of the flight.
The Magnum spun the 12x8 at 11,500 on the ground (15% Nitro) and it unladed a bit in the air but that was it. I was going to try a 11x10 but a bad switch...you know the rest...[&o]
A Jett 90 with the short RPM muffler or a YS110 with a 13x13 would be the best way to go for unlimited speed.
