Hi All,
Being a tight english man - I've decided to build my own ESCs for my second heli (Dragonfly), how difficult could it be?
Anyway a bit of research found quite a few DIY ESC sites:

BrushLess

Personally when I saw the simple design and price of Thomas Scherrer's kit (first link), I thought why bother designing the pcb etc.
I have emailled the guy and await confirmation of my order. Imagine having an ESC that you can upgrade by just adding more FETs!!
