4 in. BB Mecanum Wheels

Greetings Builders,
My name is David Ferreira, and I recently received and tested out the 4' BB mecanum wheels on my RX droid. When I received the wheels Kit in the mail I proceeded to assemble each wheel according to the PDF doc. Each one took around 10 minutes to build with only two tools needed. Great job on making it easy :)
After installing them, we tested them at a two-day Convention driving on smooth concrete as well as a low-pile commercial carpet for a total of ten hours. After the event was over I proceeded to inspect the wheels individually for any signs of wear or damage. There was none. Each roller would still free spin with no effort. A few characteristics to point out about this wheel is they seem to have an increased grip, and with 12 rollers in such a tight form factor, your speed is slightly increased due to the faster transition time from roller to roller.
A few details about the Droid, RX weighs 72lbs and stands 3' tall. His wheelbase is 13 inches wide and 12 inches long. Here is a link to where you can see his performance at this particular event. https://www.instagram.com/p/Cm5hir0D4RX/
Overall I am impressed by the engineering and quality of this product. I have tested other wheels in this same form factor and all have failed for one reason or another. Whether it be the rollers breaking down or the nylon core cracking and eventually breaking away.
If you're looking for a mecanum wheel built to last I would defiantly recommend the 4' BB for your robots to droid project. Happy Building

This wheel is so smooth. Hands down the slidy-est wheel I've ever driven. Almost feels like a swerve.
