These nylon wheels have been serving well. Recently replaced the nose wheel rim with the 5# nylon rim and saved 13+ ounces. Good value.

Good light weight wheel but can’t take a lot of side load

Light, tough, precise and capable of necessary loads. Im very pleased with the wheel. Since no brake is available, Im designing a disk and caliper to use with the wheel. This should favorable affect net weight by about 1.5 to 2.0 lbs. Im excited to complete the assembly.

I need a single for an ultralight sailplane. This wheel saves me 1.5-2 lbs. I am designing a caliper brake to work with the wheel since no brake is available. talking with Azusa, they welcomed the design and would consider it.

Here is an ideal super light wheels for ultralight aircraft 103 exemption: light, respectively strong for the weight limit of 103 (to be safe though dont exceed about 370lbs max force per wheel on rough landing), easy to assemble. Using inner tube is a must. Here I found the ideal set for these wheels - everything mounts well together: 6 wheel #06-02700, Ribbed round tire 13-400 x 6 / #7005, Azusa Tube # 7133 410/350 X 6 , valve 90deg, part #06-00075, I would recommend aircraftspruce to sell all these as a set for aircraft application instead of the go-cart sawtooth set they currently sell. Also would be great if they publish the max designed load limit of this set with ribbed tires. Thanks to aircraftspruce for their great support of our projects. Vladimir Blanshey eBirdman, TN
