I think there is an xbee that will be good for a couple of kilometers, or roughly 1 and a bit miles ? The Xbee is cheaper, and i thought from the number of mentions of it and threads that it must be superior. But i know nothing(yet)
Ive bought programable cards and readers and propellors (gadget gangster and another similar one and a couple just on a bread board :) but now, i dont know what to do with them ? My original idea was too expensive and hard to solve too many problems.
