Black Beetle Drive Bogies and Black Bug Drive Units.

The Black Beetle is a four wheel, completely self contained power bogie with its own electrical pickups. It is relatively lightly constructed, with 2mm diameter axles and is intended for use in model railmotors hauling one or two trailers or multiple units. The weight on the centre pivot should not exceed about 100g (~3.5oz.). For locomotive applications the use of two Black Beetles is recommended.

The Black Bug is a single axle drive unit for rail tractors, small rail cars and similar light self propelled vehicles. They are assembled from the same range of motors, gearboxes and wheels as the Black Beetle range. They are available with either a 15:1 or a 27:1 gear ratio, but do not have electrical pickups fitted.
