This project has been in my head for a LONG time… and now, thanks to major software progress and custom hardware development, it’s finally starting to become reality.
In this video, I show off a custom 3D printed component that will become the heart of my upcoming RC motor dyno system. This won’t just test motors — it’s being designed to analyze motor performance, battery behavior, efficiency, load characteristics, and much more.
The goal is simple:
⚡ Better motor development
⚡ Better optimization
⚡ Better real-world performance data
There really isn’t anything like this available for the RC crawling world right now, so if I want it to exist… I have to build it myself.
This project is still probably about a year away from becoming fully operational, but the foundation is finally here, and I’m excited to share the journey with y’all.
This thing is going to open up a LOT of possibilities for future motor and ESC development.
