FS120SP-Surpass
Fitted with a Roots type supercharger, the power output of the FS120SP is raised by a staggering 30~40%. More importantly, the torque is also dramatically increased, enabling the engine to be operated under heavier loads - with coarser pitch propellers at lower rpms - which is very important in F3A contest flying where competitors qualify for noise reduction bonus points. Other features of this impressive engine include a PG-02 fuel pump, C14 carburetor with built-in pressure regulator, nine ball bearing and a special safety locknut assembly as standard.
Like the Goldberg Super Chipmunk we think this model is an ideal low wing scale model for the beginner, if fitted with a suitable engine size of around .60 to .75 2 Cycle.
