Some people prefer the dive test, some the inverted test. I have been told to only use the inverted test on symmetrical or semi symmetrical airfoils, not TD foils like the 7037, and not on flat bottom airfoils. The theory is that it should not take much down elevator to fly the ship inverted it the CG is set correctly. "Not Much" is the same precision measurement that is used in the dive test. You know, it should recover "Gently". Jerry R.

For the "Setting up a full house Plane" site. I have heard mention of testing the setup of a plane by inverting it. What does this do and what are the particulars.
