I'm wanting to use the Lego Arctic crawler as a chassis for a robot I'm building. I need to figure out how to modify it so it's 4 wheel drive. It's the first set I have put together so if anyone has suggestions on how I can modify it to accomplish this I would greatly appreciate it. It will save me a ton of trial and error. I have the necessary power function motors I just don't know how to build the axles and such to attach the motors and make it function. I know I need to order more pieces but I really don't know which ones I need. I figured I would give this forum a shot before I abound the idea entirely and try some thing else. Thanks in advance
