Posted September 23, 20159 yr My two last buggys ware small and quick, so this time I wanted to build a big one. And here is it: big and faster than you probably think... To get better control in long range I have used SBrick(actually two if them). The overall size is 50x30x21 studs (~40x24x17cm). The wheels used the from the Unimog set. To do it as fast as possible I have built it very simple and light, it only has 698 parts, and the weight is only 1.3 kgs. It is powered by 4XL motors, 2 for each axle with 1:3 final gear ratio. With so many motors it needs to use 2 batteries and 2 SBricks. The max speed is around 8kph (5 mph). I have used a special configuration for the motors to get the best possible preformance. So the transmission is very simple and it only has 4 gears... and nothing more. Simple and effective. The suspension configuration is a double wishbone in both axles. It is every soft and with long travel, essential to go fast on bad terrain. The steering are controlled by a PF Servo motor and working steering wheel Available Free LDD Instructions, to download it go to my swebsote HERE Finally a video in action: Enjoy!!
September 23, 20159 yr Always a pleasure to see your work! Looks very robust and usable. I suppose after the twin rotor, a 4 gear model is a relief :)
August 26, 20186 yr This looks like a good candidate foe me to build with the 2 SBricks I am about to order - but how do you change the gears? Do you have to stop the buggy and select them manually or is it automatically done via SBrick?
