ursa with plow and salt spreader

thingiverse

This is actually a fusion of multiple designs, including my typical RC truck body, the Ursa monster truck chassis, the plow, the grille and headlights, the truck box, and salt spreader. Thanks to everyone who has shared their ideas. The truck runs on a 540 80T brushed motor with a 60A ESC on a 3S 7000mAh LiPo battery concealed in the truck box. All lights are triggered by a servo connected to the plow drop servo, while the salt spreader is controlled by two 9G servos linked together and driven by LEGO chain. I love having a functional and versatile RC truck. The salt spreader design took some time to develop and combine with another concept that I have not shared yet. If someone wants to try it out, I'd be happy to provide more information. It does work. Update: I've uploaded various files to complete this truck, but I don't have the time to explain everything in detail. The salt spreader requires bearings or printed ones and should be lubricated for smooth operation. It uses LEGO Technic chain to drive its gears, which can be purchased on Amazon or eBay. Two 9G continuous servos are used to power it. Unfortunately, I've misplaced my file on mounting the salt spreader to the truck bed, but I'll add it if I find it. The plow utilizes two MG995 servos: one for tilt and one for lift. The lift servo will require modification of the Ursa front frame piece to fit in place, as I did mine without a proper design. A pulley wheel is also needed to pull the cable that lifts the plow. I left out the grille and lights because they can be sourced from the truck body designer if needed. Feel free to ask questions; I'll respond as soon as possible. Don't let this description seem too vague – it's actually quite straightforward, using readily available parts in simple designs.
