Description
Not competition legal — read before buying
This part is NOT legal for FIRST Tech Challenge (FTC) or FIRST Robotics Competition (FRC). It is sold for training, practice, prototyping and general robotics use only. Do not build it into a robot you intend to compete with.
Need more speed? The NEW 40:1 and 20:1 MAX TorqueNADO Motor Gearboxes give more rpm when compared to the 60:1 gearbox included with the TorqueNADO motor. These gearboxes are designed with the same 37 mm diameter as the original 60:1 gearbox, while using the same 6 mm D-shaft and alignment pins, so getting the additional speed you need is a breeze.
The 40:1 gearbox provides one and a half times more rpm, equivalent to approximately 150 output rpm for the TorqueNADO, while the 20:1 gearbox provides three times more rpm, equivalent to approximately 300 output rpm. Both result in a reduction of power or torque.
Comes prelubricated and includes three mounting screws.
