Foams for an off road?
 

My club may start running an off road heat, they run on carpet - are there any foams available for 1/10th off road wheels?

Dan

get your hands on some 1/8th track foams wich are unglued.. put your offroad wheels up in a lathe and make them flat then you can put on your 1/8th foams on them, might be tight but it should fit real good.. i recommend some contact or 2 componenet glue though.. ca-glue is not good

or use schumacher mini pins on carpet like everyone else!!

They won't let us use any spike as they think it damages the carpet......

It doesn't really damage the carpet, only if they want to run touring on the same carpet the buggies tend to kill the traction for the saloons with the pins.

Run some foams! Soooo quick!

Time to find a new club, dude!!

Yes it's mainly a TC club with foams on carpet, this is just an off road heat in amongst 3 or 4 TC heats.

Without checking i would guess standard 200mm foams would fit straight on!!! they fit on my Kyosho TC which uses same size Hexes. I just had to use a washer to stop them rubbing on the wishbones.

they fit on the rb5, if you cut the fronts to be abit thinner :) but the feeling gets a bit like a gocart with such small wheels

Got some 8th foAms and new rims gonna try lathe them down.

How much should I leave on the foam? 10mm sidwall??

if you leave them 10mm high, make sure you round them very much or theres a big chance of chunks getting ripped off if you hit a cerb or rolls it..

i would think 5mm is well enuogh.. but i used foams at least 10 years ago :)

What a messy job! Did it last night and here's the result....hope it works!

Seeing as others are using worn dirt tyres or road tyres (ie rubber on carpet) I 'should' have the advantage!

looking good mate :D

Cheers :thumbsup:

Well, race was yesterday and the foams were a complete SUCCESS!!

My nearest challenger was 5 laps back!! :thumbsup:

The car was immense - so stable over the jumps too.

Nice job :)

what foams did you use? I would be sooo tempted

I used Enneti 40 shore donuts (PM me for UK link), one full donut width = a rear + a front 2.2" 4WD buggy wheel.

Here are the steps I took (use safety specs!)

1. I started with a rear wheel, put it on a tyre truer and removed the ribs - best to connect the motor so the wheel is spinning away from you.

2. Then I stopped the wheel, removed it from the truer and pushed a donut over the rim until it was square.

3. I then stopped the wheel again and I made a mark with tippex on the outside of the foam using the width of a front wheel as a guide.

4. Using a stanley knife and with the assembled wheel/donut spinning on the truer I cut vertically down by the tippex mark until the excess foam detached - voila, here's the start of the front tyre.

5. I then glued the tyre onto the rim (now looking more like a completed assembly) in several places front and back using a tube of contact adhesive from B&Q.

6. After about 20 mins I started to true the donut down to size, I aimed for 7mm wall size (this bit is messy!).

7. Once I had my desired foam wall I used some sand paper whilst the wheel assembly was spinning to round off the edges of the foam.

8. Then did the above steps 1 to 7 for the other rear and then the front wheels!

I left them overnight to allow the adhesive to set.

The buggy was on rails - nobody could come close, I can't think of a better tyre to use on carpet really.

Luckily I had inherited a hefty tyre truer from a friend last year and didn't know what to use it for until now!

Cheers,

so a pair of rear doughnuts will do a full set of wheels for a 4wd buggy?

PM me the link!

That is correct, a pair of rears will do a full set of wheels for a 4WD 1/10th electric buggy ;)

PM sent.
