Fast RC Off Road Car

I would like to share my latest off road car with you. RACE uses one L motor per wheel and is therefore fast and powerful. Here is a video (lots of slow motion) and some instructions. Let me know what you think.

    @bartneck, I suggest you post it on Rebrickable

    Nice work. My biggest gripe about the 4x4 Crawler was how slow and underpowered it is. Might be worth modding using your one motor per wheel approach. I also like the flexibility you got with the joint in the middle. Very clever.

    nice build but be aware that with all that power youre likely to twist axles and damage parts

    @Si_Dorking_Surrey_UK: Wow! I had no idea Lego motors could generate that much torque until I read your post. After doing a few quick searches, it looks like the motors can do some pretty serious damage to gears and axles. Thanks for pointing that out.

    I posted RACE at Rebrickable, including video and 3D file. Enjoy!

    @bartneck, saw that on Rebrickable facebook this morning ;-)
    I have a similar size RC car, not as fast but RTC Steering, double differential using 3 M-Motors.
