YS120SR Helicopter Engine

This large displacement engine is the next generation of helicopter power delivery, and is the ultimate power plant for your 90 class Heli. Weighing in at 544 grams, the weight of the 120SR is equal to the YS 91SR, only with more power! This provides you with an ultra powerful lightweight engine that can easily handle any 3D manoeuvre you throw at it. Plus, with the same mounting dimensions as the 91SR the engine will fit most 90 class helicopters with little to no modification. If you believe that there is no such thing as too much power, the 120SR is the perfect choice for your 90 class bird.
