Designed to succeed the original 46AX, the new 46AX MkII retains the same mounting dimensions, but O.S. has updated the styling to bring it into line with the current range of AX engines. That means the introduction of the highly efficient and unique cooling fins to keep temperatures under control while the precision carburettor, with its angled needle valve keeping fingers safely away from the propeller disc, offers the linear response across the entire rpm range that you would expect from O.S. Optimised to produce its power at low RPMs - and thanks to the highly effective ‘Powerbox’ silencer - the engine produces even less noise too.

Perfect for sports, aerobatic and scale applications.
