With the recent ramp in controversy surrounding unmanned aircraft systems (UAS) and the media frenzy trying to scare the population into thinking airliners will soon be falling out of the sky, the FAA has (re)released some guidelines for those interested in operating aircraft remotely.
Its fairly simple to stay within the guidelines.
-Don't fly near real airplanes
-Don't fly an aircraft heavier than 55 lbs.
-Don't fly beyond your line of sight
-Don't fly for payment
Until such time until the government can fully develop operating regulations for integrating unmanned aircraft into the existing airspace infrastructure, these will be the rules to follow.
I anticipate that the FAA will permit commercial operation on a case by case basis, with only a single operator approved at this time. This includes 6 test sites that have already been established across the Unites States.
