Description

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.

I should have read the review from nioa2 before wasting my money on this. No wonder it is on sale but still not worth the money. The shafts are plane, no threaded ends and nuts so you can lock the shaft to your landing gear. And you need a very strong lock to counter the breaking action. No manual how to mount these wheels. I wonder how? And the wheels are awfully heavy. And only one bearing at end which is not even running smooth. Feels like it has sand in it.

Not a well designed product. Dual bearings are really needed as one really tiny bearing on the outside of the wheel is supporting the entire load of the wheel. Play in the bearing results in the brake coil plate and the tire plate making contact. Not good. Think "stop and go, thump, thump". Very HEAVY. This item looks great on paper, but in reality does not work well. If you have a machine shop and can make the modifications, this product may be useable, but out of the box, it is a crap-shoot. For those interested, applying more voltage does NOT make braking greater, as the controller is current regulated. 3S or 10S, the wattage consumed is the same.
