Yes. I agree. First of all, in testing, we need to agree on what the aircraft represents.
I've committed a new version of the C-172r that has a different prop, has the weights
changed, and better represents a typical C-172R, I think (and unmodified one - see the
TCDS). I've also added comments found in the TCDS and Cessna propaganda, FWIW. I don't
know if I am personally interested in modeling a pristine aircraft with ideal performance,
either. IMHO, it would be better to model an aircraft as typically seen and flown in the
real world.
