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.
