Finally a reliable braking solution for large scale aircraft, these wheels use the same system used on high-speed roller coasters for launching the cars along the track, just in reverse. Magnets set into the outer rim of the wheel react with the coil in the center hub. When a current is passed through the coil, the magnets react with the magnetic field generated and slow the wheel down, thus causing the aircraft to brake. As there are no friction parts in the wheels, they cannot wear out so reliability and longevity should never be an issue.
You can even use braking progressively to avoid locking up the wheels when applying the brakes, just set them up on a progressive channel on the TX operated by a variable channel.
You get a pair of braking wheels and an Electro Magnetic Brake Controller. This plug's straight into your receiver for signal and draws power from an external battery pack, you can use anything from 3-10s LiPo.

These landing gears are NOT AT ALL meant for 15 kgs planes or jets. The bearings used between the 4mm axle and wheel are very thin 2x1.9mm and cannot sustain even the first landing. The braking power is surely impressive and reliable.
The wheels started having a lot of slop after the first landing, I replaced the bearings with 5x11x5 and changed the axle to 4mm. Its working perfect now.
