Commercial Applications
Although RC helicopters are generally used by hobbyists for recreational purposes, they are sometimes used in applications such as low altitude aerial photography, filming, policing, and remote observation or inspection. Some companies make RC helicopters specifically for these uses.
Recent (2006) FAA regulations grounding all commercial RC model flights have been upgraded to require formal FAA certification before permission to fly at any altitude in USA.
Remotely piloted or autonomous helicopters powered by electric motors instead of by gasoline or diesel internal combustion engine, with electricity provided by fuel cells or batteries include a type of small unmanned aerial vehicle (UAV) which can carry 10 pounds (4.5 kg) weight of payload.

Famous quotes containing the word commercial:
“If men could menstruate ... clearly, menstruation would become an enviable, boast-worthy, masculine event: Men would brag about how long and how much.... Sanitary supplies would be federally funded and free. Of course, some men would still pay for the prestige of such commercial brands as Paul Newman Tampons, Muhammed Ali’s Rope-a-Dope Pads, John Wayne Maxi Pads, and Joe Namath Jock Shields—”For Those Light Bachelor Days.””
—Gloria Steinem (b. 1934)
