To be totally honest, I think our system is easy going, but with my full sized background in mind, I really like the German certification system where you have to physically prove structural integrity before the first flight. This can and does cause problems and lets be honest, I'd hate to deal with it, but it is a very robust system of certification.
Thanks

Dave have read the German rules, and they would be a PITA hear as well as most modelers would not have a clue on how to do the numbers if they did miner structural changes, But then again I have not done a math problem in the last 20=years except to add/subtract $$$ from the c/a
