Yes I believe that at the TPS was origionally designed to be a 200+ MPH Ducted Fan engine capable of smoking any of those turbine junkers for the money. The turbine manufacturers paid Evo keep it under wraps and detune it with the flywheel weight and 3 bladed RPM reducing prop. It was then discovered to be an amazing powerplant for 40 size trainers. You must have taken the weighted flywheel and prop off and foiled thier plot.
