Hey, I didn't bring the subject up
The options available are the kit version and the RTR rock racer version, with the ARTR available shortly if you are getting it in the UK, although the ARTRs have been available for some time in US and Hong Kong.
The RTR is good if you don't have spare radio gear, especially a reversing ESC, but if you get into it you will end up replacing them anyway. The RTR has plastic suspension and steering links, instead of the stronger aluminium ones on the kit and ARTR. The RTR and ARTR comes with the upgraded straight rear axle and diff lockers as standard, but the 4WS parts can be fitted to them if you want. Dez at Radio Race Car usually uses 4WS, but to get most use out of it you need a 3 or 4 channel radio to let you control the rear steering separately. Most people just leave the rear end on the kit one locked up or upgrade them to the RTR style.

The ARTR has a few upgrades from the kit, but the 4WS is missing. The ARTR has the high clearance links for better ground clearance, the improved heavy duty diff lockers and the new improved straight rear axle. The kit still has the option of 4 wheel steering, although you can still fit the parts to the ARTR and 4 wheel steering isn't allowed for competition use. You also get in the ARTR a better body for more clearance than the kit and RTR ones and Proline Hammer tyres with memory foam, which work much better than the kit and RTR Axial tyres.

If I was buying an AX10 myself I would be tempted to hang on for the ARTR.

The problem is once you get one there's all the extra goodies you can get for them from the crawler specialists like The Crawler Store and RC4WD

I dont have the money for one at the moment anyway, hopefully the ARTR will be available when I do. I do have a 4ch radio although it is a plane radio so competiting with it would be out of the question... (Not that I imagine there is any organised crawling done here anyway)

I quite like the sound of a dig setup for doing tight turns also.

If I could get one setup with my current 2 channel setup to start with then see about adding a dig setup and 4 wheel steering. I have a reversable LRP speedo and a hitec 5925 servo so part of the way there :P

Depends on what you want to do with it and what you consider necessary.

Driveshafts seem to be the only problem with them, fitting the Axial driveshaft rings protects the yokes, then the only problem is snapping the shafts themselves if/when you bind up the drivetrain. The absolute best fix for this is the MIP spline driveshafts that will cure any problems with them permanently, but under normal circumstances the kit driveshafts are fine. Most of the AX10s at the nationals were running as standard and performed well, the most common mod was the high clearance links that come on the ARTR.

Mounting the battery on the front makes the biggest difference, the standard mounting place is the worst position it could possibly be. Options are to either sort out a pack specific to the truck, like on Joshs truck above, or to mount a stick pack or lipo on top of the front link.
Changing the one piece upper link to two separate links will also give you lots more articulation for very little outlay, but more obvious torque twist from the chassis.

You then start eyeing up a dig setup which locks up the rear wheels so you can turn much tighter by pivoting around the rear wheels, better chassis such as the TCS Edge which means you don't need a body so lower CoG (the best AX10 at the nationals used one) but none of these parts are necessary to crawl with.

You might want to have a butchers on rccrawler.com - this one is shipping in limited quantities - http://www.rccrawler.com/forum/showthread.php?t=107126

For you oOple crawling newbies, a DIG is a disengagement, where you disengage drive to an axle so the still driven pair of wheels pivot around the locked ones. It looks pretty impressive too!

*edit* Heh, didn't see you defined a DIG above terry..

These will illustrate what dig does for the steering, both using an AX10. You will need a spare channel on your radio for it.

would a converted wheelie king not be a viable option. doesn't seem to take too much to make it work, and with a how-to (http://ukrcrc.com/site/index.php?opt...d=48&Itemid=43) it seems a good alternative. what do the veterans say???

The Wheely King is a very viable alternative to the Axial, the ones competing at the nationals did very well and went better than the standard AX10s. But they don't come set up as crawlers.

That link illustrates the good old make it yourself style which has made crawlers popular for lots of people, and the same reason the majority have had no interest in it as it doesn't come ready to go. I know it's just making up a set of extended links and sourcing propshafts from something else, but there is an easier way. HPI make a rock crawler conversion kit to change the chassis and suspension over to a proper crawler, including new links, link mounts, servo mount, diff locks, body mounts for 1/10th shells, new wheels and tyres, everything you need to convert it. But they aren't widely available like the AX10 is.

Nice and simple to convert, but the advantage with an AX10 is that it's almost ready to go well out of the box and there are loads of upgrades that just bolt on with no fuss which is why they appeal to most people.

It is cheaper than the AX10 if you aren't bothering with competition performance though.
