Master Airscrew AS Gear Box 2.5:1 RC Gearbox - MAS3025K

The Master Airscrew 3025K AS Gear Box is a 2.5:1 reduction gearbox built for electric flight RC aircraft, letting you swing a larger, more efficient propeller from a smaller motor. This RC gearbox (part MAS3025K) sits between your electric motor and prop shaft, gearing down the rotation speed to convert high motor RPM into more usable torque. It's a popular choice for electric park flyers and scale models where a slow-turning, larger prop delivers better thrust and a more realistic flight profile than a direct-drive setup.
