FS-30S Surpass

More Surpass power – same compact size.

Regardless of the type of flying you're into, Surpass engines enhance the aeromodeling experience. And if you fly planes with .26-size mounting applications, the FS-30S Surpass for O.S. will be a much-appreciated upgrade. It's an economical way to enjoy the benefits of a 4-stroke engine—more muscle to swing bigger props, quieter, more realistic sound and better fuel efficiency—without making any modifications to your model. With 20% more power than the FS-26 engine, the FS-30S Surpass is ideal for exploring the performance potential of aircraft such as the Great Planes Piper J-3 Cub .20 or the T-Craft. Tweak the performance of your smaller planes simply and affordably...with the FS-30S Surpass power plant from O.S.!

The FS-30S shares these quality features with other Surpass engines:
