It's to let air in and out. If the holes weren't there the weight of the car will push air out of any small hole it can find as the tyre squashes. If there is no hole the air can't get back in and you end up with a squashed tyre.

Gotcha!

Should I be putting in 1 hole or more? How big should the hole be? I have drilled one 3mm hole in each wheel so far.

Or if you seal it real good then the tire bounces like a basketball...not real good for the handling

I use two 3mm holes opposite each other, to help balance out the loss of material. The foam in the tyre keeps any dirt out.
A UK specific problem, but having bigger holes also makes it easier to get the water out after racing in the rain.

Default Yokomo 001n Set Up

Hi,

Would anyone have a good starting set up for a narrow/rubber 001. I will be running on indoor carpet with low grip..21.5 motor with shorty lipo and laydown servo.

I had a look on Petitrc but can't find any rubber indoor setups?

Any tips also welcome as this is my first F1..

Thanks,
Keith

Many thanks, I have done the same, two 3mm holes opposite each other. It annoys me that I have to wait another couple of months until I can actually run this car!!!

I see you are from the UK - Any decent tarmac tracks up your way?
I'm having real problems finding anywhere that has on road racing

If you fancy racing an F1 on tarmac, realistically your only choice is the Stafford summer series. Even Stafford goes indoors in winter. Most racing is done indoors on carpet, the F1 Nationals is at Tamworth. If you are looking for somewhere racing F1s, you will find there are very few clubs that run them. For normal club racing I will be running my F1 on my own as I'm the only person here still running F1, so outside the big meetings I usually race 1/12th or WGT.

To find somewhere I would suggest starting with the clubs list here, although it is quite old and a lot of clubs don't exist any more. You do find a lot of clubs are concentrated in particular areas, with big gaps in between. Here around Manchester I have the only on road club, but nearer the Wirral there are several on road and not much off road.

Need a little help.......have an F104W with the Wolf body. I remember reading somewhere on this thread that the kit tires that come with the car are crap, and
need to be replaced. What are the tires I should get?; and bear in mind that I'm looking for the wider tires that fit the 70's era of that car. The car will be raced on an asphalt parking lot

Well I can't get to the track to run or test and all the people around here are running on road cars in the streets and local parking lots around my house.

You want wheels and tyres for the F103. Pit Shimizu makes F103 equivalents of their F104 tyres, with similar part numbers. Part number 571 and 572 are the popular F104 tyres, so for the F104W you want 541 and 542 tyres for the F103, and a set of F103 wheels made for foam tyres. Rear tyres are 5mm smaller in diameter than the kit tyres, but the motor pod will let you lower the axle to use them fine.

I posted this in the F104v2 forum, but i'll share it here as well since it's the general F1 group. I have been struggling with front end grip, and i have tried all sorts of front tires, but recently read that Caster helps with these cars, so i found out you can make top arms from some parts i already had, here's my result



I have noticed my front tends to "hop" a little making my car push, i'm hoping this will help me get a better setup, and i will also try to move my shorty lipo as far forward as possible by removing the tabs on my servo and bringing it another half inch forward.
