Scale Flying...
I find this most aggitating! You take a 1/5th scale airplane to the Scale Master Qualifier. Your flying is judged by several different people who each have their own perception of what is scale to the real airplane. They ding you, because you are flying too fast, or that is what they perceive. Many scale models can not fly a true scale speed, due to high wing loadings. The problems overcome to keep a 100% scale airplane in the air are increased as the model becomes smaller. The aircraft reduces in size, but the air molecules don't. No one uses a redar gun or other device to know at what exact speed the model is flying at. Each judge has their own opinion at what speed something is moving through the air. It's like several different eye witnesses at a traffic accident giving their interpretation as to how fast the involved vehicles were moving. I build scale and fly for fun, but I don't get too hung up over the flying part, as long as the low fly bys are right down the runway!
