MiniSpinner
The MiniSpinner is a re-working of the ever-popular RoadRunner Compact box, designed specifically for use with our high-performance, 10mm coreless motors. Its flexible, swinging-arc design allows this ultra-compact combo to be fitted into the smallest of spaces.
The drivetrain uses the same durable, tried-and-tested components as the rest of our range, but the etches themselves have been paired right down to fully exploit the smaller dimensions of the powerful little can motors.
Ratios of 34, 45 and 60:1 will cover a wide variety of operational needs – a shorter motor coupled to a high ratio (60:1) would be ideal for smaller engines, however, the longer 10mm cans have power to spare and can easily handle 45 or 34:1 reductions, even with, heavier, big-wheeled locos.
