Cheetank: FAST Lego Tank

Today I was playing around with my Lego's (like I do every day), and I came up with an idea. Why not make a tank and gear it as fast as I can? I made a tank that's just a simple chassis, and I geared it 3:1 for speed so it flies across the ground. I named it Cheetank because it is fast like a Cheetah. When I tested it on obstacles, I was surprised to find that this tank performs almost as well as my greatest obstacle climbing tanks even though it has little torque. The sheer momentum of Cheetank bearing down on an obstacle enables it to drive right over it without stalling. The speed of the treads also helps it to achieve plenty acceleration even on rough or slippery terrains.

  1. actually, gearing it 1:3 would make it slower, but i get your point. wasn't maelstrom geared 5:1?

  3. @qlaxx22: Thanks for correcting me, I fixed it now. The Maelstrom prototype was geared 5:3, but the final version was geared 3:5. Neither of them was as fast as Cheetank is. You're correct that the two bars in the front are important. They let Cheetank's momentum push it upwards over the obstacle. Without them it would often ram into obstacles without climbing them.
