“Building and flying model aircraft has been my hobby 78 years. Now you are trying to take away that hobby. You will not only take away that hobby from me and many other modelers but will destroy many a business related to the hobby. Have you considered that effect on our economy? Your regulations will still not stop the individuals who want to cause damage or destruction from doing same. You have to concentrate your efforts on the suspect individuals and not on the model hobby as a whole.”
