Hi Jim

Basically you need a pushrod slaved off the flap rod - or even off the flap horn.  The horn on the canard must be over the top (same side as the flap horn) so the canard moves the same direction as the flaps.

As for ratio - your mileage may vary!  Recommend you have some way to adjust the throw.  I would suggest something like 3:2 (more canard than flap) for starters.

What is a Tri-Canard?  I have flown and still fly the canard the Dick Sarpolous published years ago.  It has a forward stab/elevator in front of everything and flaps on trailing edge of wing.  The flaps on trailing edge of the wing have the movement cut down to where they barely move.  The elevator in front moves about 30 degrees up and down.  For up the elevator goes down and flap goes up and vice versa for down.  If you make them go the same direction you will not accomplish anything other than make the plane rise or descend.  I have witnesses that the Blue Goose will do a AMA pattern, not a 500 pointer but a recognizable pattern when engine is set right.  DOC Holliday

Thanks Dennis,  how did it fly?  I guess it wasn't worth the trouble of pursuing it.  Also is there plans for it?  DOC Holliday

Denny,

I recall when Archie was having severe vision problems at a Nats. Very narrow 'tunnel vision'. If what he was looking at got outside the field of view, he had trouble recapturing it. One of the brothers was always ready to go help him if that happened. Was it you who bailed him out at a (?)Lake Charles(?) Nats? I was watching, partly because of the unusual layout, and partly because your (?)Eclipse(?) was one of the sharpest turning models I'd EVER seen.

More to the point, I recall being VERY impressed with the tri-surface model's turn ability...
