There are a lot of instructions out there about balancing classic wing configuration glider models. The center of gravity should be approximately 25% to 30% from the front edge of the wing, which is easy to control. The next step is flight tests and adjustment by adding or removing weight or moving the wing forward or backward. Using this approach I constructed several gliders with stable horizontal flight.
But what can be approach for balancing canard configuration glider model? Is it the only recommendation for the canard wing to produce more pitch applied to the center of gravity then the main wing produces, is it possible to verify this somehow before testing flights?
