Scott,

It would be prudent to get ahold of somebody who knows the aerodynamics of 
a canard to speak about this matter.  You have or had 3 CFI's that work and 
fly these things every day.   I have talked to two of your paid  A&P/CFI 
types and they told me in no uncertain terms you cannot deep stall the 
Velocity if it is within gross weight and CG.  Now maybe they were 
referring to everyday kind of flying, I don't think so.  I was pretty clear 
about my question.

PURELY HYPOTHETICAL , that's what that is.   Scott you are associating the 
aft cg deep stall flying characteristics and making the leap that that 
scenario apply's to a properly weighted aircraft.  With no basis in 
engineering analysis or practical experience.

Oh yeah, have somebody sit in the front seat and try to lift the 
thing!  Ever done that?  Its plenty heavy.

You don't know do you?

Ah, we finally get to the meat of your argument,  this is "your 
opinion"....  Well we all got those....
