This is an amazing model wut I did was I added a 1x6 rod (like for off road stuf) in the top and bottom so it doesn't tilt around and then I added some soft springs to make it well.. soft and of course it has drive and steering :P
Thank you so much! just what i needed, BTW how do you come up with these dimensions for stuff? i can NEVER build this small without it falling apart when i blow on it, or it just falls apart while being made... Thanks again!
