Warning- These insanely small RC builds are for the experienced hobbyist only. This project requires in-depths knowledge on soldering and programming RC car transmitters. I try to include everything you need in order to improvise a micro RC build.  This is not an exact guide.
I recommend you DO NOT USE your favorite car if this is your first micro build.
