I present my latest crawler:
http://www.brickshel...ry.cgi?f=545871
It's main concept is similar to my previous crawlers: nothing unnecessary part and weigth, as simple and reliable technik, as it can be. The chassis is enoug flexible to do this: http://www.brickshel...Crawler/021.jpg - so you don't need more advanced suspension in this concept. Two XL motor drive, one M motor steers the vehicle. For power supply there is one LiPo battery and a V2 receiver built in.
The front part is heavier, thanks to the small wheels in the front rims and the ship weight. The chain holds the weight in position.
This crawler also has the usual rock crusher tires, in my case, from RC4WD.
The body is partly from the 8437 official model:

I lookde around my room in the beggining of body building time, and the 8437's body in my showcase just gave himself to connect
with the chassis. I wanted to make a tubular body/frame.
Has a fake L6 motor in the back too:
As video, there is the first part (from 00:40 to 20:55) of this video:
