i was pretty much just messing around with my new bot when i discovered this
what you need to do:
have a wired up motor you want to axle load (preferably with something on it but im not sure if this affects it too much yet)
go into the armour tab
spin the motor
select armour
?????
profit
me and plazmic inferno were testing this out and we think that the lighter the armour you choose, the further out the axles go. you can also then spin the axles without them going back into place.

the results we got varied a lot and i have no idea what made them so different. perhaps this glitch could be used for something else but idk
