ELECTRIC BRAKE SYSTEM:
The JTM electric energy control aircraft brake system is replacing and reshaping the traditional pneumatic braking system. This will enable the builder and flyer to have an easier installation and better control on the distance of landing without adding extra flying weight.
The brake system operates on a input voltage of 7.4-22v. It can be directly plugged into the aircraft battery or use an external battery from 7.4v. Adjustment is easy to make by adjusting the capacity control clockwise to increase power and counter clockwise to reduce power on the hub screws. The control box plugs into an auxilary port on the receiver. The leads from the brakes in the wheels connect to the control box.
The tires are constructed of the same rubber that automobile tires are made of. This leads to improved traction upon landing and taxiing on the tarmac.
Set come with two main wheels and brake controller.
