Re: BEST MECANUM WHEELS

OP: we've only used the AM 6" mecanum wheels (2014 Aerial Assist), and we were far happier with the wheels' performance than with our decision to do mecanum. They're also quite durable; our practice robot in 2014 had a CoG that was way off towards one wheel, and our practice field was asphalt (and not very recently refinished). This set of wheels survived about six weeks of driver practice, and while we would not use them on a competition robot, we keep them in our tote of prototyping wheels in case we need to take mecanum "on the road" again.

Edit: Regular (AM-0136L, -0136R, -0137), not HDs

And about the TB nano, I had the same question as Mike Marandola, so let me follow up:

We have had nothing but success with Versaplanetaries and toughbox minis and will just use those for now on.
We have never used the TB Nano, but our air cannon is built on a nano tube structure, which is essentially two TB nano gearboxes built into opposite ends of the same piece of tubing, plus an idle drop-center axle in the middle that we link to one end by chain. We've had significantly more trouble with these gearboxes than any of our other AM gearboxes, though not quite to the extent you describe, possibly because they don't have to mount to the frame, they are the frame.

I'm also looking forward to trying out the new TB micro, which seems to have the same construction as the TB mini, but a profile much closer to the nano.

Edit: Ninja'd
