Whiplash Test 3

[kenneyth]

5/16" is WAY too thin for a 13kg bot. My featherweight uses a 3/4" hardened steel shaft and even that's pushing it.

well i chose that so it would fit in the skateboard ball bearings i had and it was initially designed as a hobbyweight but it is 7kgs

it was never meant for serious competition anyways
