Whether you prefer 'Offset' or 'Inline' design styles, there's a gearbox to suit
you in this range.

All types are ball-raced and made from metal throughout.
Where possible, lightweight aluminium is used in place of steel to save
weight.

Most gears are precision CNC cut to ensure optimum 'meshing',
which in turn reduces friction and hence power loss.

Each gearbox is
provided with an aluminium propeller driver as standard.

The 400 gearboxes
suit motors with 2.3mm shafts, the 550 and 05 versions suit 3.17mm shafts.

Each of the 400 'Offset' gearboxes is provided with three different pinions so
that you can choose the best ratio for your model.
