You could always adjust the pulley ratios so that the wheels are all driving at the same rate.

Or move the wheels a bit closer, and put intermediate friction drive idler wheels between them. Less work than belts, and about the same weight when you take additional pulleys into account.

Friction drives would also get the wheel speeds all the right ratio, as it transfers the surface speed of the wheel, not the angular velocity of the axle.

I like the idea and I have the weight to spare will see how I go,

WhizzBee is now painted, has a pointy arrow and self righting bar.
apart from any more little mods she is done Cool now going to concentrate on spares and packing.

How did your weapon motor hold up? It looks like you don't have a support bearing on the opposite side of the chassis, did you have any issues pre-loading the shell onto the friction wheel?

I've only seen one fight video of it but it looks to have some nice potential.

Righto so last year at nats Whizzbee did well.

the shell get bent in where the tooth was from the force (no photo sorry)
the aluminium floorplate turned into a bannana making everything rub together.
and zipties holding escs together just does not work(trashed some wiring and tz85's Sad ),

but on the upside did cause some carnage!

so far I have replaced some aluminium supports with steel and am trying to get rid of the floorplate altogether (taking advice from rotwang at nats)

Welded on a biz80 ring (holes drilled for speed and weight Razz) hopefully the side will not dent in from the teeth anymore.

'If in doubt, add more steel' - Whizzbee should be much tougher at the next event.
