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.
