I just don't think you have thought through the ramifications of applying professional testing, certification, investigation, data-gathering,
reporting, analysis and implimentation to this hobby. The costs in time and money would be prohibitive for the average modeler and at the club level. To do what you want would require a team of pro accident investigators at every flying site.
The focus correctly has been, and should be, adhering to a simple, easily understandable set of safety guidelines, and most importantly, operate in a safe environment.
But 804 it would solve most of our problems if we did like Franklin suggests... the hobby would be dead and gone...thus no more problem. He is full of...good ideas.
