O.S. MAX 28XZ Engine

Purpose designed from the outset to be raced in \'Truggies\'. The extra capacity over a .21 ensures maximum punch out of the corners and with 3.31PS she is no slouch down the straights either! The \'racing\' nature and increased capacity of this engine requires a slightly bigger flywheel than a .21. Carburation is courtesy of a smooth and responsive slide carburettor and an SG style crankshaft is standard. Requires the OS \'T\' style glowplug.
