the stick planted hard in the dashboard
I wound up in a similar situation once, by varying the routine "hydraulic failure" emergency in that I turned the power off after the gear had been lowered in the ILS pattern; the 5º "up" tailplane datum shift had of course been activated by this time.
My student fell completely for my cunning plan and selected wheels up immediately after the go-around. When pushing the stick up against the dashboard didn't stop the aircraft from pitching up quickly even further, his "You have control, Sir" was overstating the case a bit
The nose was a bit high and the speed uncomfortably low to restore normality by lowering the gear again, but rolling to a very large angle of bank meant I could let go of the stick (no hands = load free) so I could put the hydraulic power back on before we ran out of IAS completely. ATC were highly amused by this performance, but fortunately didn't klype to the Thought Police in Standards, who never heard of the incident.
PS I didn't do it again, ever.
