In a straight ahead descent, the wing is producing 1g lift and the stall speed is the same as in level flight.   You guys may be thinking of the change in stall speed when *initiating* a descent (pushover, less than 1g for a moment), or when *terminating* a descent (pull-up, or flare, momentarily more than 1g).

Dave, et al,

 

In a descent, the stall speed is different because the wing is not lifting the same weight as it would be in level 1-G flight.  However, that only accounts for the vertical component.  The hi-G turn (like 70 degrees of bank) is still adding sgnificant load to the wings.

in scotts reply he includes a graph of stall speeds vrs bank in a level turn.remember this turn around maneuver is not level but descending so the stall speed doesn't increase as much as the graph but if you get ground rush and try to arrest the descent rate in the turn you will probably stall
more reason to practice at altitude and see if this is something you might want to include in your bag of tricks
