Just something else to add to my rough draft. Okay guys, here's an updated version:
As members of the US Senate, I'm sure you see many issues come up on the floor. I would like to address another that needs to be brought up.
Between the FAA and Congress, an activity that has been around for at least 70 years is being regulated into history. That activity is Model Aviation. This is an activity that started out with uncontrolled aircraft, moved on to control line and eventually to the radio controlled aircraft we have today. Through much of that time, an organization called the Academy of Model Aeronautics has been in existence as a place to get plans, assistance and information on building and flying aircraft as well as insurance. The AMA has also picked up the task of "lobbying" Congress in support of the activity. Unfortunately, due to some of the actions taken by the AMA in the recent past, Congress and the FAA have set a path that will see the hobby of building and flying R/C aircraft become a thing of the past. Something else to consider is how many school age children and teens could become interested in aviation and science due to exposure to the principles they would have to learn to be able to build and fly an R/C airplane.
The FAA has recently mandated that the flying of R/C aircraft will be illegal over 400 feet about the ground and is looking into limiting the locations to some of the existing model airfields. This has serious implications to the hobby:

• The airfields are all controlled by organizations that are aligned with the AMA and will require membership to both the organization and the AMA just to fly. This will cost those that are active in the community a significant amount of money BEFORE they would be allowed to fly the first time. More importantly, the costs of membership to both the AMA and the organization that operates the flying field can prevent someone from getting into the activity. Planes, radio gear and the associated ground support gear are not cheap so being forced to add another $150 or more can and will prevent people from joining this historic activity
• Many aircraft models are now sold for use at parks and/or play fields. Being made of molded foam, they are marketed as being safe for people to fly with little or no instruction by the industry. People buying these planes would now be required to join the organizations that control the flying fields AND THE AMA or be in violation of the proposed regulations. Worse still, most won't know or understand these regulations, resulting in people being prosecuted for what they didn't know and further burdening the court system when it can be easily avoided
• The regulations being looked into will have little to no effect on those that have or plan on buying multi-rotored vehicles(drones) as they don't require a large area to take off or land. It is these "drones" that are the actual problem and not conventional model aircraft or helicopters. It was a drone flown from the Seattle Center that did circles around the Space Needle's observation deck and was used to look into apartments in downtown Seattle as well as cause a dangerous situation for several FAA recognized helipads, some being at hospitals. It was a drone that flew into the "Big Wheel", at the Seattle waterfront within weeks of the first incident. Now we have the latest incidents, a drone flying into a Twins vs Pirates game on September 5th, another flying over a Yankees vs Rays game on September 2nd , a third over Fenway Park stopping a Red Sox vs Rays game on August 14th while another landed on the center field of a Wrigley Field, stopping a Cubs vs Indians game on September 16. These events show how the FAA's "broad brush" approach to all of R/C aviation is missing the target, that being drones.

As you can probably see, the safety issues of model aviation are not with the conventional aircraft but, rather, with the proliferation of drones and the ease in which they can be flown and the ease in which the operator can pack up and "disappear" before anyone from the local police or sheriff's office can get to the location the operator was flying from.
At this time I would request a chance to talk with you about the issue and see if there is some way to prevent the hobby from becoming a thing of the past while protecting our national airspace
Thank You for your time
