What wheels will fit an original Ultima with no mods?

[Boons]

:thumbsup:

Well, I wanted an Ultima, I have two coming!

Sorry for probably asking this when it has been asked a million times!

I am trying to source an original set of wheels however I would like another set for racing.

Cheers

The 4mm front axles limit your choice of front wheels, as well as old Ultima wheels you can use Schumacher Cougar 2000 front wheels. By adding the HPI front wheel adapters (http://www3.towerhobbies.com/cgi-bin/wti0001p?&W=001254575&I=LXN055&P=K) you can then use any Tamiya 2wd front wheels.

The rears are simpler, Kyosho invented the 12mm hex drive so there are plenty of modern wheels that will bolt straight on.

Do the Triumph wheels fit?

All tamiya wheels can fit but need the special 4x11 ball bearings

CRP has 2 versions of 5mm diameter axles for the front: standard width and 5mm wider (10 in total).

The J-concepts Rulux wheels for the traxxas 1/16 e-revo will give you more offset than other modern 12 mm hex rear wheels. D-racing also has some wheels for that revo. Both will take 2.2" buggy tires.
The larger offset is more in line with the original wheels and means your car won't loose width when going modern

Yes, Triumph wheels fit straight on.

All tamiya wheels can fit but need the special 4x11 ball bearingsI use the HPI adapters I linked to earlier, you can then use Tamiya wheels with the kit 4x8mm bearings.

Thanks all.

So for clarification I can get the Rulux wheels and they will go straight on the rear, I can then get the wider axles for the front, get some bearings and fit Tamiya wheels. What front wheels would match the rears?

unfortunately those rear wheels appear to only come in black.

I gues you could put some b4 parts in to get the front to take b' rulux wheels, but then you' dhave a white/yellow and black theme going

The only combos that work and are easy to find are Tamiya I'm afraid. The grey dish wheels from the sand viper are my prefered combo, though they have drawbacks also: bearing fitment is not very tight upfront and the plastic is souple but hard to get a good bond on.
Desert gator works too but is not looking so good.
G-fighter (or whatever it is called) has brittle plastic. Nice for a shelfer since it comes in many colours, from Carson also. Bit small for 2.2" rears though.

I've also got D-racing wheels: Dex210 for the front, and RB5 for the rear.
The front is hard though: had to trim the innner bead for clearance and the axles are the CRP wide ones with a section trued away.

And finally with standard width CRP axles: academy griifin front and rear wheels fit perfect. Very nice looking, but hard and a bit brittle plastic.

Thanks mr. ed

I've ordered some bits ;)

What would you recommend for the steering set up and which turnbuckles all around?

Cheers!

[mr. ed]

The steering set-up on the stock ultima chassis is a tough nut to crack. I don't like to fit the servo lengthwise, but to put it sideways you have to cut the servo's ears... and then you're stuck on how to get it to stick in place well.
A low profile servo does allow you to try more configurations. Sorry I don't have a better reply.

[Boons]

That's no problem, thank you!

Can I ballrace the standard set up?

[mr. ed]

I don't think you can. Check if t has bushings in it. Ifso you just get bearings of that size (IF there any busings in it I bet they are 850's)
