Description

Unleash upgraded power without sacrificing fit. The O.S. Max .55 AX delivers .50 scale muscle packed into a .40 size envelope. Its redesigned carburettor and muffler boost performance and ease, featuring a rear-angle needle valve for convenient tuning and a squared-off muffler for hassle-free cowling installation. Take your flights to the next level with the .55 AX - power, precision, and ease, all in one.

  • Power Box positionable muffler
