I built an airplane ESC from a kit. Works well, a little expensive.

If you _really_ want to build one to _really_ learn how they work, fine. If
you want to save money, I'd say forget it. After hearing the discussions on
ESC in the EFLIGHT maillist, I know that it'll take me years, if ever, to
design a reliable and safe ESC. Overcurrent protection, safe start
sequence, input glitch filtering.... Believe me, you need those features.

If you want something to start with, Elektor had a 84-based (I believe) car
ESC design about two years ago. You have to buy a preprogrammed chip
though, since only schematics and theory was published.
