This is a stock 1:1 scale replica of the Pratt & Whitney R-4360 Wasp Major propeller engine. This engine utilizes 40 1.25 meter reaction wheels and produces a modest 230 kN of thrust. The bearing is very strong, and the engine is extremely smooth when operating. Its root-part is a large girder, allowing it to be easily attached to another craft. It should be noted that the thrust value mentioned is when the blades are set to maximize stationary thrust.
