FPV Quadcoptering for about 80 quid
My work colleague (we'll call in Charles) wants to get into FPV and we've been experimenting with a few cheap options. There's now a ridiculuously cheap way to get into it. It all comes from the Chinese copy-house Eachine and the components are crazy-similar.
Assuming a single battery for flight (to start with) and you have a soldering iron or access to one (or live near me).
