Jim,

Your post concerns me even more than Scott's!
 See Velocity Views volume 7 Safety Corner by Duane on
deep stall avoidance and recovery; see more of the
same in volume 8 Safety Corner under "Deep Stall";
also see volume 12 Safety Corner under "Aerobatic
Warning."
 Pls note that 1) it is possible to stall the the main
wing by flying outside of the normal flight envelope
(i.e. aerobatics), and 2) this can lead to a deep
stall - from which you might be able to recover - but
it probably WON'T "go right on through flat and deep
stalled on its way to straight down." 
 Glad to hear this was a non-event for you and your
buddies in other canards, but it doesn't seem
reasonable to imply the same will be true for the
Velocity given the factory's testing and warnings to
the contrary.
 Anyway, my main point was how the main wing can be
stalled - not to open the deep stall recovery can.
