...Virtually all of them are toys that cannot stand up to the rigors of an FAA airworthiness certification. As "aircraft" they will be required to meet airworthiness requirements for deign analysis, as well as rigorous ground and flight test just like any airplane of rotorcraft. That means they will have to endure fatigue analysis and testing, address engine failures, drive system malfunctions, demonstrate controllability following a rotor drive system failure (vertical lift models), identify time limited components, come with an approved and enforced maintenance program, and be inspected by FAA specialists for certificate renewal. Likewise, the "pilots" will have to be trained, tested and licensed. This is a long overdue decision. The cost for a certification will drive the price through the roof...thank goodness. Owners are about to be fined heavily for unapproved operation...excellent. Not all owner/operators are idiots, but enough of them are to demand regulation. I do believe the honeymoon is over.
