OS Engines MAX 75AX Nitro Aircraft Engine, .75 Size w/ E-4040 Silencer

OS Engines MAX 75AX Nitro Aircraft Engine, .75 Size w/ E-4040 Silencer Fits the same mount and bolt pattern as the 61FX. The angular head design looks great and significantly increases surface area for better cooling. Includes the new Power Box™ muffler, designed with more volume for increased power while still being very compact. A diagonallyplaced needle means no remote needle valve is needed. The third engine in the new ‘AX’ range of high performance 2 stroke engines fills a convenient gap between the existing 61FX and 91FX, yet features the radical new style pioneered with the fabulous 55AX. The new 75AX is supplied complete with the latest ‘P-Box’ design silencer for improved noise suppression. By keeping the lower crankcase dimensions the same as the 61FX, you can be sure that it will fit in all models designed for a .61, making a power upgrade very simple. The 75AX features the latest O.S. ringless piston technology with multi-layer cylinder coating and high precision Type 61A carburettor with angled safety needle valve assembly.
