T-400GD  Motor System

T-400GD Motor System

Efficiency and more flying time go together — and with the T-400 GD (Gear Drive) Motor System, so does economy. It's ideal for larger park flyers and small electrics — and for pilots who already have a wiring harness or ESC on-hand, it's also a very affordable way to "trade up" from direct-drive to gear drive. The T-400 motor offers bushings for economy and ferrite magnets for strong performance. The aluminum gearbox is open and assembled, for easy access to the smooth-running brass pinion/nylon gear combo. Its 3:1 gear ratio lets the motor run efficiently — and gives the pilot the option to replace the included 10x7 prop with bigger, "pitchier" props.
