 My friend Fred who building the twin with me forgot to lower his
 landing gear on his Velocity XLRG during a precotional landing
 practice in Pahookee Fl  3 months ago ,and try to overshoot but he was
 to close of the runway and the prop hit the runway surface and the
 lower part of the firewall and still flying to the grass on the left
 side and hit so hard the fuselage was a complete scrap.
 Fred as been to the hospital with his instructor for over a month and
 he had spine injury, he is walking now with a body scan and he does
 lot of therapy every day .
 Fred is recuperating very well
 I check for  wings and their seems fixable if the spar is not broken
 which I have the feeling it still in good shape, the strake fuel cell
 still good and canard is fixable and I will need less surface.
 I changed my design and we will reuse as much as we can from the
 Velocity for the twin construction plus the wing will be extended 24"
 each side and  adding flaps and slats.
 I did a schematic wiring diagram as we will add to the gear system to
 prevent the same mistake.
 I am at the stage of  extending my garage of 25ft plus an outside
 concrete slab 12'by 35' and should be completed in a few months.
  I will start the twin construction after then.
 I am following all your developments on the rotary every day.

       Bonjour: The Swedish put the canard foreplane in their Viggen
above the level of main wing, the same applies
    for the French Rafale and the Eurofighter, and to the new Saab
Grippen, I have no idea about how many
    airplanes with a canard surface have the foreplane in the same level
or below the level of the main wing;
    according to the attached images from the French 'Aviation
Magazine', better results are obtained if the
    Canard plane    is above the main wing plane.

    I guess also that an arrangement as in the Curtiss P-55 Ascender,
with the foreplane
    angle of attack having the possibility of changing from 0º to +/-
90º, and the foreplane including also elevons,
    may help theoretically avoiding the accident of a 'Velocity' canard
airplane described in 'Flying', Oct 2012,
    page 36, when a blade of the pusher propeller broke, and the pilot
pulled the stick instead of what he should
    have done, pushing it to have the plane diving and gaining airspeed.

    As discussed, there's a quite detailed article about basic
calculations in canards: 'Canards, design with care',
    by    Robert Burns, in the magazine 'Flight', around February 1981
or 1982, back issues are of free download
    in the 'Flight' website.

    If the foreplane has a sufficient negative dihedral, as in the
Rafale, Grippen and Eurofigher cited, the induced
   rolling would be in the right direction when the 'A' shaped canard
acts as rudder.

     Hope you like this. Have a good week. Best regards. Salut †
