A combining reduction gearbox was driven via extension shafts from the power sections.

The design was then modified by the addition of a reduction gearbox to drive a propeller.

It consists of a motor coupled to a sensor for position feedback, through a reduction gearbox.

It is basically the same as the old one, but has a 3:1 reduction gearbox fitted.

The epicyclic reduction gearbox was incorporated in the propeller spinner.

Oil-operated reverse reduction gearboxes were fitted, rather than an additional, heavy reversing engine.

An electric motor drives, through a reduction gearbox, a shaft on which is arranged a series of cams.

Power is transmitted to the propeller via a reduction gearbox.

However, the engine proved unreliable and suffered from failure of gears in the reduction gearbox.

Further development of the Mamba removed the reduction gearbox to give the Adder turbojet.
