Here's my latest MOC, a C model for the 4x4 Crawler (9398) set.

Features:

• 4x4 drive achieved by 2 hard coupled L motors, with an overall 1:1 gear ratio
• 1 Servo motor for steering
• Pendular rear suspension*
• Easily remove the battery box by pulling the red pushpin on either white curved panel, pulling the smokestacks out, lifting the roof, pulling the two axle/lift assemblies keeping the BB from sliding around, and pull the BB out.
• Openable hood

LDraw, and Stud.i files available here

Notes:

I have assembled this physically, didn't take any pictures though.

The LDraw file is wonky in spots, such as the rear from the motors, back, and how I couldn't get the back axle tilted to connect the top rods, you should be able to fgure it out though. 

 

*not sprung, couldn't fit them on nicely, this this is made to go fast, not rock climb anyways

It is pretty good, could be better with regular suspension on back.

Thanks, and I do agree, it would have been better with proper suspension, I just couldn't figure out how to make it work, without having 2 big springs sticking up behind it.
