Hey Everyone! Here is the successor to my Lego Technic Chili Crawler, the Cactus Crawler It took about half of a year of design and revision to reach its current state, of which I am proud of. THE VIDEO: youtube Features: - 3 L-Motors for drive (two in the rear axle, one in the front) - M-Motor and a small linear actuator for front steering - Rigid, triangulated 4-link suspension for the front axle, with large, soft, black shock absorbers - Extremely rigid 2-link rear suspension with ball-joint pivot point on top of the axle, similar to that found in the RC "Mantis" crawler - 100% Lego-legal custom curved rear links that, with how the main cab is shaped, provide exceptional ground clearance towards the rear of the crawler, allowing it to climb up relatively large vertical structures such as street curbs - Very minimal, light bodywork - BuWizz for extra power and SBrick for a great, custom control scheme Note: By the time I finished designing the cab and it's battery enclosure, BuWuzz had not yet come out with the update for their iOS app that allows a single joystick/slider to control multiple outputs, so I was forced to use an SBrick with the BuWizz, providing the extra power from the BuWizz, but with the ease-of-use and great custom control profiles of the SBrick. When used with the SBrick, the BuWizz does in fact still provide more power than the standard Lego 8878 LiPo battery box. - RC4WD 1.9" Krypton scale tires - Two green pieces so that I can call it the Cactus Crawler ;) LXF hopefully coming soon, the tires can easily be found with a quick google search of their name. YES, I know, there is no body. This is meant for performance, meaning I made the cab as small, light, and rigid as possible. I will be able to reply intermittently throughout the day. I figured I'd put this up now anyway! pt
