The sweep amounts to 2", CL moving ahead 1". I'm assuming that would also move the ideal CG 1" forward, all else being equal (which they're not; see next). The original CG needed to be moved back from about 2 3/4" ahead of LE to 1 1/2", accomplished with 1 1/4 oz. of lead! With the swept wing, that figure should translate to 2 1/2" ahead of LE, pretty close.
Add to that the extended fuselage behind, with rudder located further back accordingly; subtract from that the added wing mass forward, and I'm thinking the balance should work out close to right, maybe a tad noseheavy, easily adjusted with minimal weight at the aft end.
Landing gear is actually located at the strongest part of the boom/wing combination. The booms are only 1/16" ply, with a 1/16" ply doubler coming out of the wing to the wheel mount. Plus I want to keep as much weight as possible behind the CG. Anyhow, canards don't take off by depressing the tail, but by lifting the nose. I think it will be fine.
As you have no doubt guessed, I design by the "TLAR" process, and mods based on flight characteristics of prototype. So it ain't scientific; but it's fun.
