Hi Bob,
I have a Byron Mustang and there aren't many Mustangs that have a higher weight, with all the 4 blade hardware, etc, and therefore a high wing loading. However it's not very fast, with a Q42 and that prop, which isn't very efficient. Do you think something like that would something like that be acceptable to most cd's?

Bernie,
Notice the word "should", which is a suggestion. If they wanted it a requirement they would have used the word "shall". AMA is not specifying the type of plane, thank goodness, just recommending some features it "should" have.
