I was a 4 time NATS judge at Muncie IN for control line...one of the things I'll never forget is becoming friends w/ British CL flyers. They ACTUALLY had to pay and apply for 4 things to fly a string controlled model airplane! 1. permit to use an IC engine. 2. A permit to own the fuel for said model. 3. A permit to use a model airplane field. 4. A permit to use a " noisecontrolled" implement......AKA mufflers required
What part of INSANITY do you get from this?....
