Like the FSa-56, the crankcase breather system has now been incorporated inside the engine to negate the need for an external vent and the excess oil that emanates from it. A propeller locknut assembly is of course
standard.

The new F-5030 silencer is very effective, thanks to it's internal baffle and carefully matched internal volumes and passages. The design allows a huge range of outlet positions to accommodate almost every model. Even the distance away from the engine can now be adjusted.

The latest 60RA carburettor now features a 'constant velocity' inlet for improved throttle response and reduced spitting.
