Here is a wide shot of last year's featherweight arena:

Even from this far back you can see the gap at the bottom of the barrier. Its not clear to me what the floor is - steel or wood? If its steel, then neoydium magnets cast in jake's urethane wheels might be a winner.
About CF and antennas, I never really found how bots like Morpheus got around the problem - CF top & bottom, ali sides and nothing obvious hanging out. Any ideas? Jake's flat antenna would come in here.
What do people think about drive motors? Power, size, voltage, etc? I have those Thingaps, which have super high efficiency and develop 350W peak power running on only 14.4V. This gives a very high power to weight ratio, but on the down side, they spin at 17,700 RPM so a gearbox with around 25 to 30:1 reduction is required. I think the new SS2 gearbox might do the trick. Its relatively cheap and the HTI motor it comes with has a similar shaft and mounting.
Why not just use the HTI motor? we could, but it has lower efficiency and needs a higher voltage to get the same power. that equals lower power to weight and less weight left over for armour and weapon.
Alternatively we could use the team Delta DeWalt setup. Its more work to use and requires an outboard bearing. I mostly don't like the dewalt plastic gearbox. You don't hear much about it, but the yanks break heaps of them. _________________ Australian 2015 Featherweight champion
