Presenting the 8258-B Crawler,

Designed and built as an entry for the 'Crawlify your set' contest [AMS1]

I'm a huge fan of b-models in general, but the 8258-B has always been one of my favourites due to great looks and an easy to modify. Or so I thought...

In the end, I reckon about 85% of the chassis has been custom built. There are two L motors situated just below the cabin. One powers the front axle, one powers the rear. Both axles have differentials because, being independently powered, loss of traction is a lot less likely and it saves my poor pieces from becoming mangled. Because the 8258-B is rather small (read: narrow) I had a lot of trouble designing a front axle that could house a servo motor without limiting the range of suspension travel. Eventually I gave up and ended up modifying this axle to accommodate a differential (well deserved credit to the amazing @Madoca 1977).

However with that said, I have made sure the bodywork stays almost 100% true to the original. The only alteration I had to made was to the rear wheelarches to make room for the balloon tyres:

Modified wheelarch:

Also, the front winch kept scraping on obstacles I was trying to climb over so I switched this out for a bullbar, however the two are easily interchangeable.

Anyways, here's a video of this thing in action. As always, please let me know what you think. Whether it's praise, criticism or telling me off for building ANOTHER red and black model (I have other colours, I swear!!), I'd love to hear it. More images can be found in this bricksafe folder.

Enjoy =)

Because I suck at proofreading

Very cool MOD, I like the flexibility of the axles and the chassis, which allows a ton of travel. Good work!

And I don't believe you have other colors.  

Great work really like the way this came out. This is the way Lego should have released this set. Your mods have given this set true off road crawler capabilities.

It is indeed a great MOD, but where is the crane it is supposed to be pulling? ;D
