OS 120 Supercharged Engine FS-120S-SP 120S SP FS 35522

Great condition for age, may need some new bearings, but has not had that much run time, just stored with after run oil.

Comes with exhaust stack and mini manifold.

Also included is a soft mount for beam mounts.

Instructions included. A lovely running motor, very smooth last time it ran a few years ago, been in storage.

Original box, still in good structural condition just has wear and tear.

A rare OS FS-120-SP 120 supercharged four stroke. This is an OS four stroke with a Roots supercharger at its rear. Initially made for FAI flying, this is designed to run up to a 14 x 14 prop, so it's a powerful beast at 2.5 BHP @ 10,000rpm.

Great engine for the collector or to use as intended.
