Hi CD

Thanks to everyone who posted their experiences with the Stealth Wheels last season!

I was the main designer on that wheel and I wanted to share a bit of our design intent. We set out to create a really competitive FTC wheel (see the 8mm version here) and at the same time create a wheel that could be used all over an FRC robot; for intakes, drive trains, shooters, internal conveyors, roller claws, etc). We have seen and heard from teams that a main drive train gearbox can round out the internal hex on the wheels, but this can be solved by adding a hex hub (here) to the wheel.

A few quick pros and cons to using the wheel in a drive train:
Cons
-Lack of a 3D tread prevents mechanical engagement with carpeting (lowers total traction)
-May need to add a hub to prevent round-outs

Pros
-A stiff sidewall edge helps to prevent the wheel from sliding sideways (like when getting pushed by a defender)
-Like stated earlier, the wheel is inexpensive
-The wheel is easy for us to make so its easy for us to keep them in stock
-The 6 hole pattern in the wheel's center body means it works with all the AM sprockets, hubs, and other components.

Let me know if you have any questions
Thanks
Danny
