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.
