ZXX,
thanks so much for your kind words!

Folks, if I may, please do not make assumptions of what we do and don't do to test models. The testing our aircraft go through is VERY extensive, including using local modelers, a variety of VERY skilled pilots who can not only say "something's not right" but exactly what and how to fix it, etc.

Trust me, I know what the pitts went through. (My husband is one of the test pilots, i get to hear the stories! :-) And i can stake my name, and reputation, on the level of testing multiple copies of that model endured without breaking a sweat, including production aircraft.
