Build guide for the tiny indoor quad the RS90. Coming in at only 78 grams and still crazy fast. Not an easy build and more focused towards people who love a challenge and enjoy the build process. You could make this build probably lighter by around 10 grams with a lighter bottom plate and swapping out some of the wires to smaller gauges.
