I had not thought of VG's on the canard. Any pics available? Of course, I'm a ways from flying.

> I wish I had added the cuffs.  I was excited about having the short chord wing because I would be able to go faster at lower altitudes.  My Velocity flies 200 mph at 4000 feet with a parallel valve IOX-360.  But I would trade a few knots at the top end for a lower stall speed. Since I didn't put the cuffs on the main wing, I didn't feel comfortable putting vortex generators on the canard.  Mine are only on the main wing.  If I had the cuffs on I would also put vortex generators on the canard and drop my stall speed so I could land slower.

I've read good and bad concerning this modification. I would like comments on this modification. Good, bad, should it be removed, should I keep it. Let me know.

>> The author got other basic facts wrong.  It wasn't Rutan that mounted an EZ on the back of a truck to investigate deep stall... it was Danny Maier, and it was a Velocity.  Also, the one other fatal deep stall mentioned in the article was a Velocity where the builder had modified the fuel tanks by removing the rear      wall of the tank and allowing the fuel to go all the way back to the spar to gain more fuel capacity.  That, and the fact that he flew into a thunderstorm, caused the accident.

>> There are mistruths, he states 3 prior accidents, two landing in the ocean.  He fails to mention one of those was intentional by the factory, the test pilot elected to stay in the airplane, he had a parachute, and soft landed in the ocean.  That plane  was flying the next day. He states that any canard airplane can be deep stalled at 128K by either aft cg or abrupt pullup! First half truth/Lie is that it takes a way aft CG, since the redesign you need to be 2-3+ inches or more aft of aft CG limit and get the airplane in a very odd attitude, which at 128 knots I think thats probably not doable.  That you can deep stall a V by doing abrupt maneuvers is blatant speculation and I've never heard of anybody doing it. I've made some pretty aggressive maneuvers and been in some wild thunderstorm generated turbulence, by myself(aft CG) and never felt any indication at all of a deep stall.  And the accident plane hit really hard!  All three known deep stall accidents, one intentional, all hit very softly, and hit flat. This accident turned over, that would not be characteristic of a deep stall.

>> He took a few facts, dressed up a few assumptions, sugar coated a few lies and just made shit up!  I think he has a thing against canards and is playing fast and loose with the facts to paint the V as inherently dangerous.

>> This month's Flying magazine has an article (copy attached) about a Velocity accident in 2009. The plane lost a prop blade and this author believes the pilot mistook the violent shaking to be flutter, pulled abruptly on the stick, put the plane into a deep stall, and had no way to use engine power to break the stall.
>>  
>> I wasn't a Reflector member in 2009 so don't know any more than what is in the article. Is there anything to learn from this apart from the obvious? (Make sure your prop blades stay attached, but recognize the symptoms if they don't, and fly the airplane.)
