RC Soviet tractor DT-75 Kazakhstan (1\10 scale)

cults3d

This model was born from a GTA SA mod conversion in ZModeler and adapted to print in SketchUp. It's my first project, and I made plenty of holes after printing it. The walls are quite thick due to the bad filament I used, which makes the model prone to breaking. Some parts were glued together with super glue, while the cabin was reinforced with a paperclip's wire and some soda - also held together by super glue. I even created door hinges and handles using paperclips. This tractor runs on four yellow gears powered by an Arduino. While it's not the most powerful for outdoor use, it's sufficient for home or asphalt use. Adding 3S power might increase its performance, but for now, I'm running it on 2S. Because it requires tank-style control and I only have a classic car's control system, I built a radio-controlled system using Arduino (Nano with NRF24L01 and L298N module). You can use either a simple discrete RC from a tank toy or professional 6-8 channel equipment. Each side needs 44 tracks, 2 main cogs, 2 rolls, 2 carriages (karetka), and 4 small cogs. The carriages and rolls are mounted on M4 screws, while the small cogs stay on M3 screws with some spacers. The gears are attached using M3 screws with spacers to align them in a straight line with the second gear. The front blade is optional and must be glued from parts: otval, otvalr, and their mirrored counterparts. It moves thanks to a servo SG90 mounted on the tractor's front. I bent a wire hinge from a paperclip, screwed it onto the blade, and inserted it into the servo arm - an easier and cheaper solution than using linear servos. More description will follow soon. https://www.youtube.com/watch?v=LWkZRPncQ4o https://youtu.be/LWkZRPncQ4o
