Sheepo Posted September 23, 2015 Posted September 23, 2015 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!! Quote
SevenStuds Posted September 23, 2015 Posted September 23, 2015 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 :) Quote
nzmike Posted August 26, 2018 Posted August 26, 2018 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? Quote
Didumos69 Posted August 26, 2018 Posted August 26, 2018 It has only one speed and uses only 4 gears for the entire transmission. Quote
