<<they don't need to do this as these planes already have a track record of being flown in other contests over time. You know as well as the rest of us that if a manufacturer releases specs of a new plane and those specs fall outside of the rules>>

mark, what i know is that i spent considerable researching this topic several years ago and what i found was that several airplanes were not legal under the rules, and that several mfrs ignored the imac scale requirements. nothing has changed. so, no, i don't know "as well as the rest of us".

as for noise, since i am unaware of any relationship between db level and field retention, i don't understand the question.
