Sorry, it's hard for me to believe that anyone in charge would allow a 40% plane to fly a demo inside a stadium full of people. Anyone who advocates a 40% FPV demo flown inside a stadium full of people is the kind of guy I'm taking issue with.
The "blimp episode"...imagine how much easier of a shot that could have been for the RC pilot if he had FPV, plus he could have performed that stunt from the safety and comfort of his mom's basement.
