OS 55 AX with 3020 Sil.

The latest Max 55AX shares its dramatic and unique styling with the highly successful 120AX and is the third engine released by OS in the AX series.

The 55AX is designed to combine maximum power with razor sharp throttle response in the smallest possible crankcase.


Weight: 404g (524g w/silencer

Displacement: 8.933CC (0.545 cu.in)

Bore: 23.0

Stroke: 21.5mm

Power Output: 1.75PS @ 16000RPM

Practical RPM: 2000-17000

This is one awesome engine, there is little on the market that comes close to the performance of this engine at its size, except for the Enya 50 CX, which makes for an alternative choice.
