I've found myself with a bit of spare time so have gone and entered my drumbot into the DRG FACTS event, now I've just got the small matter of finishing the robot!

I'm trying to work out how to run power from the brushless to the drum, unfortunately I've left myself with no way of getting a 'closed' belt like a timing belt on there so need a belt that comes split and can be joined in-situ. The best option I've found is polyurethane round belts like these: https://www.ebay.co.uk/itm/Orange-Sm...8AAOSwkShY9oGn

But I'm not sure how many/what diameter to use, has anyone with experience with these belts got any suggestions? I was thinking maybe 3no. 5mm diameter belts?

Can't comment in the drum drive, but I've used split fan belts on cars before now, but only ever as a roadside repair, that said I don't see why they wouldn't work so long as you can tension it properly.

Is there no way you could remove the drum to fit a belt? Personally I'd feel better entering an arena with a one piece belt, but I'm and ardent over-engineerer(erer) ha
