What's the verdict on a xxx4 graphite?
 

I have one of these kicking around from a couple of years ago when I had more time.

Should I revive it (still works nice, but the kit is a bit dated) or sell off and replace?

its a great car, i just got one for a very cheap price. if your willing to do some mods and throw about 25 quid at it, you could have a weapon on your hands.

whats mods???

I always liked mine.

The mods involved extending the steering bellcranks and using some touring car parts to straighten out the front hinge pins.

Not sure what they would be like with LIPO's and brushless, but the drive train was always bullet proof.

really quick accl with brushless/lipos drivetrain stands up good just got to keep checking diffs as u would anyway, its a missle out of the corners no problems at all with lipo setup

So, what sort of brushless/lipo set up can the car handle?

Not that I'm enough of a driver to push it to it's limits, just curious...

i run 6.5 X12 brushless motor & 5000 lipo turned up quite high too:thumbsup:

Just bought a broke one and re-building it as we speak. Going to post some photos up soon. Mr Bloomfield seems to working with it just fine.

Darren Bloomfield did use the XXX4 indoors
But has switched to the XX4 for the outdoor season

Do you know what the reason is for the change?

Thanks

This is like a "historical fact" by now. The XXX4 has a much better drivetrain (more solid). But the weight distribution & geometry is suited for more or less flat tracks (US style).

The XX4 OTOH is THE King of off-road, as it works perfectly on ANY surface: Flat or very bumpy! Fast and VERY easy to drive too! The discontinued XX4 is now very, very old (13 years?) - and was designed when motors and batteries were much less powerful. Still OK on low/med grip, but those belts (3) get into serious trouble on high grip (astro).

You may still get it to work today, but it's discontinued and it can be a bit hard to find parts, but far from impossible :) And you may need to do some mods in order to make it solid and reliable enough.

Now, a small company called X-Factory tried to combine these two into the perfect car: The X-5. Single belt drivetrain, but with the weight distribution and geometry of the XX4. It was OK on low grip, but we could never get to terms with belt skipping on med/high grip. This car is since a couple of years discontinued (the chassis mould broke). They are now working on it's predecessor: The X-7...

Here's some XX4 (and X-5) upgrades:

I've seen the XXX4 in action outdoors on several tracks, and it looks fairly good to me! So unless you're aiming at 1st position I'm sure you can do decently with it! Good luck! :thumbsup:
