3-D Printable RC Car

thingiverse

This DIY RC car was designed to bypass the need for costly rc car motors and intricate linkages. When I spotted the Open RC truggy, I fell in love with it, but wasn't willing to shell out cash for all the additional Rc car parts required to get it running. I opted instead to use components that any ordinary maker might already have on hand. The 9-gram steering servos were mounted atop the a-arms, eliminating the need for ball joints and numerous linkages. For the motor...motors, I repurposed my DJI Phantom brushless motors, ditching gearing altogether by integrating them directly into the rear wheels. This design tweak yielded impressive speed while still delivering surprisingly robust torque. I chose to power the car using two 3s lipo batteries, paired with a hobby-grade rc plane radio. The fasteners varied from m3 nuts and bolts to salvaged plastic screws. The front wheels pivoted smoothly around a general skateboard bearing. I'm eager to see what others can achieve with this platform, hoping that improvements will emerge, ultimately transforming the vehicle into a reliable open-source machine. https://youtu.be/eop02s6c_rk https://youtu.be/3nNnf1uNtOQ
