Mr Villasensor,
I have been building and flying models since I was 3 years old (I'm 28 now). I am also a Sergeant in the United States Army with 8 years of active service and counting as, believe it or not, a UAV operator. Never thought growing up that I could get paid to fly remote controlled airplanes
Lets forget the argument of "can you weaponize a hobby-grade RC airplane" for a minute.
One very legitimate threat that the proposed licensing system has ABSOLUTELY NO WAY of neutralizing is what the media refers to as "homegrown terrorism"
People don't realize it, but the days of sending Ahmed from Pakistan to the States to blow up a gov't building are over. DHS, despite what opinion you have of them, has done a great job of making it harder for TB operatives and other such threats to get in the country. Because of this, they are turning to our own people: people who are non or unpatriotic, and sympathize with their cause. There are recruiting websites for the Taliban all over the internet (Can't just Google it, but they're out there) that people who are even just on "the fence" can go and learn about their cause. They can be reached via email, and through correspondence, can be guided on where to go, and what to do to support their cause. The case of Army Maj Nidal Hasan and the shooting on Ft Hood, TX several years ago is a good example of this. Another one is Rezwan Ferdaus, a US citizen (key word) who in September, tried to weaponize RCs with C-4. No amount of Federal registration, regulation or licensing of model aircraft could have kept him, nor any other US-born citizen from carrying out an attack.
Back to the original discussion, my Dad's (Dan McEntee) assessment of the amount of difficulty of learning to fly a simple RC trainer is valid. I can even supply a number that demonstrates this. One of the aging UASs in the Army's inventory, the RQ-3 Hunter, utilizes an External Pilot to takeoff and land the aircraft. The EP is positioned on the runway and flies the AV with a box very similar to a hobby-grade RC transmitter. Every student in every class that goes through the Hunter Operator Course is screened for the aptitude needed to be an EP. This is accomplished, simply, by an instructor with an RC trainer and a buddy box. The failure rate for the screening, according to the UAV school, is 96%. Those that do pass go on to EP training once they are finished with the basic operators course. The EP course alone is a year long, and through the course, students progress from a basic trainer, to a sportier RC aircraft, to a 1/3rd scale model of the Hunter, and finally the full-scale aircraft. The wash-out rate for the course is also high.
What needs to be understood in this is that EP students are eating and sleeping with a transmitter in their hands. They fly 8-9 hours a day for 5 days a week for an entire year. Even if someone did decide to come off of the street, who posses the brainpower to fly RC, and want to weaponize it, it would take quite awhile to learn how to fly an RC model big enough and complex enough to carry weapons, perhaps too long and too much time. Ask any modeler on this forum, "Have you ever crashed" and if their answer is not "allot" they are a big fat liar. Yet they rebuild and keep trying though a passion for the hobby. I find it hard to believe that anyone would invest that much time and effort to learn to fly RC who wasn't as romantic about the hobby, even if it means praising Allah. There are many easier ways to put a bomb on a target, like the aforementioned car, or package, etc.
Cheers,
Sean McEntee
