Correct me if I'm wrong but Martha King and my 8th grade physics tells me that everything, aircraft included, will rotate about its CG not the CP. The CP will make an upward force that needs to be balanced by the elevator's downward force. More like a baseball bat than a teeter-totter. Everything else I agree on 100%
I heard this exact explination from my CFI instructor and I took a little exception to it then and I still do since I never got a good enough explination from him to convince me.
