Hi HeavyMetallist,

Why some people persist in believing that stalled == totally ineffective is a mystery.
Please could you explain the forces acting on the tail during the stall for me?

Normally, the elevator and stab produce a down force at the tail. (to balance the nose down couple with the c of G being forward of the Centre of Lift).
During the stall, with an angle of attack of about 45 degs on the elevator and Stab, the forces on the tail must have been upwards. If not - then I don't understand why.

Please explain how holding full back side stick kept the attitude at around 15 degs until impact.
