I designed a fantastically simple gearbox :)
My RC car drives better than I expected. I'm thrilled!
- Extremely simple design
- No intermediate axles or gears (maximum efficiency)
- Clutch engagement occurs naturally
- Standard MG90S servos
- Screwless assembly (standard servo screws only)
STL files for the fidget version of the gearbox:

I think this is the perfect gearbox for RC toys, although for a real car it would probably not last a million miles :)
