dikkie klijn Posted February 21, 2012 Posted February 21, 2012 My new creation, just and only build for speed . I started with this model after realizing that the tracks on my tracked jeep really took a lot of power, wheels would be so much better. So after ripping of the tracks and adding a new front axle with steering I tested the "thing" created, It worked . But, of course, it was hideous. This forced me to take the model apart and start all over again, leaving this buggy for you guys. The model contains: 2 rechargeable battery boxes 2 RC motors Full suspension Quote
jacobkristensen Posted February 21, 2012 Posted February 21, 2012 How do you handle steering, bye reversing the power on the back wheels or? Quote
Sam42 Posted February 21, 2012 Posted February 21, 2012 That's pretty fast! Why the old style front wheels instead of four of the same? Quote
timslegos Posted February 22, 2012 Posted February 22, 2012 thats really fast for lego, nice job. i tried to build a buggy, but it failed miserably. tim Quote
dikkie klijn Posted February 22, 2012 Author Posted February 22, 2012 @jacobkristensen, The front axle steers with a return to center system. @Sam42, the unimog wheels have a lot of grip, good for a driven axle but bad for a non driven steered one. For the front wheels I needed some big tires that don't have to much grip, since this would create resistance that would slow the buggy down. This leaves me with the old tires. Quote

le60head Posted February 22, 2012 Posted February 22, 2012 That's a great buggy! It looks very fun to drive, and it jumps too! Amazing! I simply love it! Could you please share, how long do the twin LiPo batteries last for driving the model? Also what kind of Return-to-center steering did you use ? regards, legohead Quote
dikkie klijn Posted February 22, 2012 Author Posted February 22, 2012 (edited) Return to center: I just love those hockey springs . Battery lifetime: it depends, usually its about half an hour to 45 min. witch isn't bad at all I think. Edited February 22, 2012 by dikkie klijn Quote

dikkie klijn Posted February 23, 2012 Author Posted February 23, 2012 (edited) Some rather special photo's of my dune buggy. The underground is created by broken ice wich I took out of the pond. Of course the buggy won't be able to cross such a surface, but I thought it would look nice. Flickr Edited February 23, 2012 by dikkie klijn Quote
le60head Posted February 23, 2012 Posted February 23, 2012 Thanks for the info! Great new photos! I love your idea about using ice as a foundation :) Did you use a clutch-wheel for the steering, or did you connect the motor (PF-m i guess) directly to the hockey spring piece? I'm not a fan of the latter, since stalling your motor isn't very healthy for it as far as i know ? Quote
timslegos Posted February 23, 2012 Posted February 23, 2012 Ya i agree that is a very interesting base. i dont think i have seen anyone do that before! looks cool. tim Quote

But driving the buggy strait flat out is much more fun than making a corner . Quote
