The guys I work with bought a German RC helicopter (can't remember the name) that had I believe eight small electric motors and propellers that they were able to program different flight sequences from their PC, it was amazing just how nimble, quick and precise that thing was. They actually attached an infrared camera onto it and would fly it over agricultural fields to determine 'hot' or 'weak' spots within the crop, would then download the info and images for the farmers so that they could prescription spray the desired rates and types of chemicals to be sprayed.

It was an expensive little devil also.
