Re: Weishaar-Doyle LS-1 canard design

Frankenbird Vern

 A "FrankenBird", Chris.  The O-235 installed is heavier than the O-200. Do you know how the Canadian authorities worked with this aircraft and Mr. Mc Andrew and the registrations?  I believe there may be a photo or two in archives on this aircraft. I am interested in how the Weight and Balance were achieved. Perhaps an "C" number search might reveal the status and location of the aircraft? 

 BTW.. My Canard (D-fly design) does have the extra carbon ply (3 uni), has zero anhedral or dihedral (MKII stub glass gear as of now), but it is built with the GU airfoil as Dragonfly plans, as is the Wing. I'll be adding vortex generators.

Regarding the  Weishaar - Doyle canard, if you look at the Dragonfly
plans you will find they are very similar.

The Dragonfly has a C spar going the entire length. It is made a bit
smaller when it is hotwired to allow

for multiple layers of  5 inch wide uni carbon fiber to go over the c
spar once the nose cone is attached.

Then the three layers of uni or one layer of tri ply.  When they upped
the gross to 1200 lbs, they added more layers of carbon.

I think Rex Taylor may of done load tests on this.  The load was mainly
designed for landing loads as they

"sometimes" much higher than flying loads. Year ago Kimble Mc Andrew 
from Alberta Canada installed a similar wing

on his Q2 with a 235 Lycoming. I don't know if he used the LS1 or stuck
with the Dragonfly GU airfoil.

Does anyone know??  Take care---------------  Chris
