“I grew up in model aviation then became a private pilot, it is the pathway to Aviation. This NPRM is going to destroy the dream of aviation. I am deeply saddened by this. Visual line of site should not be regulated at CBO flying sites, and there should be an easy way to apply and receive a new CBO site application. The more sites, the less likely to have problems with people ignoring all of the rules and just flying whenever and wherever they want. Model airplanes are not drones!! Thanks for listening, Mike Pecue”
