Richard fired this volley in

*When flying a P-51 at 450+mph you need to have full
nose down trim to keep the plane level.* The *elevator trim tab broke
off and the aircraft im ediately went in to a 10G climb, confirmed by
the G-meter.


I didn't know you had to maintain full down trim at speed, but a LACK of
any trim shouldn't result in a 10G climb, no.

Who is the source of this opinion?
Normally, even on performance aircraft, the elevator is always going to
move to the most aerodynamically "balanced" position -- and that is not
"full up", which required considerable control input force to do.
