Bit of a bump but I recently found a good place for batteries:

I use their custom nimh packs in my ants, good if you neead a really small nimh pack for a fleaweight.

I am looking for scarletric/slot car wheels, similar to what Josh uses. Has anyone seen a site that sells wheels by size?

I use this place, they aren't by size but they do list fairly accurate dimensions.

[Andrew_Hibberd]

Thanks Josh, it looks like only the top ones have got dimensions. I was hoping to get something ~18mm diameter, so may order a few types. Do you have any issues with grip on these?

[josh]

ah, I've only ever ordered the 16mm ones, they are pretty grippy in the standard rubber compound and the marked grippier compound is slightly softer but in 150g it makes very little difference through all the comparisons I have made. I have used the Ninco 21mm shore 20A tyres, that are very soft, on my drive all day and they lack grip because even with the full weight distributed only across wheels it's just not enough. much better than dycem though. Tempted to order a pair of those fingertech wheels though, have you ever used them?

most scalextric tyres perform much better with some heat in them, which I looked into a while ago but I'm sceptical of the advantages it would give as soon as the rubber picked up some dust in the arena.

[Andrew_Hibberd]

Thanks Josh, I will see what I can find in the size I want.

[Andrew_Hibberd]

I found this web site which has dimensions for most of the wheels. Hopefully I will get these in time to try out at the AWS.

I've just got a couple of these motor hubs


(attached to a motor to give some sense of size)
from
http://proto-pic.co.uk/pololu-universal ... -40-holes/

have been looking for something like these for a while, I've seen them on US websites but finally found somewhere in the UK that sells them

As they are made by pololu they use american sized screws, but the site sell them so its not too much of a problem.

I ordered them Wednesday evening and they arrived today. the hubs themselves were just under £5, the screws to go with them were about 60p and P&P was £2 so they are about the same price as the pololu wheels but mean you can attach you own wheels to them

Awesome James, I've been wondering if something like this is available. They're like mini versions of the ones I have for the heavyweight. Means us lot who don't print our own can have more options than are currently available.

Are they heavy?
