A couple pointers here but this is was coming.

A few full scale pilots here can truly understand the nature of this attention to RC by the FAA due to the exploding popularity of UAV's.

Our national airspace system is very complicated, specially at lower levels close to airports. In order to truly understand what all the intricacies of the NAS, training is needed. If someone opened an airfield within 5 miles of an airport, they should have their head checked and some that are may have a "Letter of Agreement" or LOA with that airport such as Deland which sits on an old airport runway that has an active runway within the same field.

Bevar, I know your a commercial pilot, even though I agree with you on the demo flying/Not announcing to fly for a brand argument is a good point, I don't think its an insurance issue that an RC pilot/UAV is flying for compensation as far as the FAA is concerned legally because regardless, they are flying for compensation. According to the document, the FAA holds that ANY flying of a UAV/RC Aircraft for other than hobby is commercial work, well you need a commercial ticket to fly anything other than as a hobbyist. Ie; aerial photography, surveillance, transportation, etc. That's my professional interpretation and that's what it clearly states on that small chart of examples. Would you not agree?
