Gearbox 6mm Rod Mount 9 to 42 Ratio

Specifications:

This 6mm gearbox features modulus 0.2 gears with a 9:42 ratio. The housing has a square hole in the back to accommodate a 1.5mm square carbon rod for mounting. The square mounting hole is angles to also give the gearbox a small amount of down-thrust. There is also a 0.6mm diameter mounting hole in the housing above the square mounting hole to enable it to be mounted on a 0.6mm carbon rod. By far the lightest weight 6mm gearbox, this design does away with the brass bushings and 3mm bearings seen in other gearboxes and instead houses the drive shaft directly in the plastic housing. The unit has a very smooth action with minimal friction.
