Are servos compatible with these?
Ummm… the product description states that they use the HUB-12 hubs for 6mm motor shafts, and “Motor = any 6mm output shaft.”
I dont see those working with servos since they are specifically made for 6mm motor shafts. Even if you made your own hub and custom rims it would be difficult to run by servo becuase of their large radius and weight. Not to mention the large robot needed for these tires…
Yes, that may be a problem. Are there any wheels that are a bit smaller and are compatible with servos?
The ones that say “servo tire wheels” 
No no no, those are too small.
perhaps Custom? Im not sure they make servo wheels bigger than those. Servo wheels are ussually made for sumo or small bot applications. My suggestion would be to use 1/4 plywood to make wheels which connect directly to your servo horn. And strengthen the wood by brushing on a layer of polyurathane or just regular white glue. Ive done this a few times, and added rubber bands for traction. I also know people who have used CD’s for wheels connected directly to futuba servo horns. That might be a better option since CD’s are polycarbonate.
Yeah, they’re perfect size and weight. Thanks man!
Thanks but I don’t think it’ll work anyway.
