Small grippy wheels

[typhoon_driver]

I am looking for some small wheels (diameter of about 25mm) which have a lot of grip.

Does anyone know where i could get something like this?

Try the RC Wars guys they do some very good wheels ive got some 100mm diameter ones but they have got smaller. You will have to ask? Im sure James or Grant will be on here at some point.

We use radiator hose, but dont know if ones that small would be any good as the rubber does wear quickly.

Not quite small wheels but didnt see the point in starting a new thread.

I have got 2 x 150mm wheels with solid rubber tyre of about 1 to 1 1/2 inch thick.

I weighed the bot yesterday and am between 1/2 to 3/4 of kg over weight. I see the wheels as the easiest place to loose weight. The wheels weigh about 1/2 kg each.

Does anyone know of or where i can get some 150mm grippy lightweight wheels?
Thanks Glen

email James Cooper at rcwars@hotmail.com (im not too sure of his comapny email address!) but he sells a large range of lightweight wheels. have you tried turning your wheel hubs down? you can remove almost half the weight of the wheel on mony!

Cheers Grant

Think i might try that.

What about making wheel from ply wood and fixing a rubber tread on the outside? How durable do you think this would be?

Quite durable so long as your wheels are protected.

Another option that hasent come up here is to mill/lathe your own wheels and have them Vulkalon coated.

That is a very grippy solution, but then again Vulkalon only has the same amount of grip as the BLUE wheels. although more grip can be obtained due to making wider wheels. The only problem with that is that it costs alot to do. Plywood wheels with bycicle tyres have been used quite often and work well of done properly. They give alot of grip in the arena.

We solved the grip problem on the wheels of TAN by screwing on motorbiketire rubber on the HDPE hub, with a lot of small selftapping screws.
But this seems only a reasonable on big diameter wheels, as the rubbers isnt happy ,and wont lie down perfect. On a big wheel the lumps arnt a big problem, but on small ones its bad.

Grant,

What are the BLUE wheels your are refurring to?

I assume Vulkalon is expensive then!

[team_ireland]

It costs about 10pounds to cover a featherweight wheels, I am not sure if thats per wheel or per pair but it gives better grip than the blue ones that are sold by rc wars.

Also it looks much better than the blue ones.

Ian, the Blue wheels are the same material as Vulkalon. But if wheels are to be Vulked, then the hub will need to be made from metal yourself. The blue wheels are the same wheels that Razer , warhead and many featherweights use. They supply plenty of grip for feathers.
