Cessna 150 Price Outlook

The Cherokees have a pretty wide CG envelope, but normally operate
very far forward CG. I have done the calculations and determined that
it's *impossible* to aft-load the thing and stay under the 200 lbs in the
baggage compartment (min fuel, 70 lb pilot, 200 lbs baggage and back seats
full to gross).

Funny thing about the spins is that in the 140 manual, they don't
actually say spins are approved on so many words, but rather that spins
are not approved in 'Normal' category. I remember reading somewhere that
a test pilot was killed in the Cherokee certification when a spin turned
into an unrecoverable flat spin. Probably operating in the aft CG region
outside of 'Utility.'

I can't imagine any difference between the 140s and 160/180 in
spin characteristics. Minimally different engine weight, but perhaps the
battery further back changes moment of inertia?

FWIW
