3Dsets 3D printed RC crawlers! A little comparison between the motor and gearbox options

I enjoy building 3d printed RCs. So far, I have a few of the 3Dsets designed cars. They are fun to make and come with some different options when you build them- mainly motor and gearbox, and axle/differential choices. They are designed for a 540 size brushed motor, or a 3530 size brushless motor. Without using community modified files (found on Printables or Thingiverse) you basically use the brushed 540 with the geared gearbox- which has a great reduction ratio for crawling- and the brushless 3530 size with the belt-driven gearbox, which gives you a bit more speed and smoothness, but less torque. Some of the mods available allow the use of the brushed 540 motors on the belted drive- which gives you the torque of the big brushed motor AND the speed from the taller reduction ratio. Also, the axles come with a proper open differential, that allow the wheels to spin at different speeds when turning, like a full size car, or "locked" axles, which is better for crawling or off-road use. In most of my builds, I install my own LED lights for turn signals, brake and reverse lights, and headlights. These are not from a kit- but assembled individual components soldered together on a small PCB- controlled with an Arduino Nano- which uses the PWM signals from the steering and throttle channels from the receiver to determine what LEDs to switch on and off. The video is mostly a fun comparison between the different arrangements and how they handle on my little "test trails" in my yard, and the LED functionality. Hope you enjoy! if you want one of these cars for yourself, get one at 3Dsets.com (I am not sponsored or affiliated in any way, I just like their designs, and RC cars+3D printing!)
