Master Airscrew Gear Box 2.5:1 RC Gearbox - MAS3025

The Master Airscrew 3025 Gear Box 2.5:1 is a 2.5:1 reduction gearbox for electric RC aircraft power setups. This RC gearbox lets you run a larger, slower-turning propeller from a higher-revving electric motor by reducing the output speed at a 2.5:1 ratio. The MAS3025 is a popular choice for electric flyers who want to swing a bigger prop for more efficient thrust without overloading the motor. If you're building or maintaining an electric park flyer or sport model and need a model power transmission unit, this gear box gives you the gear reduction to match motor and prop correctly.
