The last thing to do the canard (in this chapter at least) is the check the balance and travel. First you must connect the elevators at the center hinge/inboard counterweights, then fixture the trailing edges with your I-Beam. Then using 2 shorter section of I-Beam attached to trailing edge find neutral, and check for 28 degrees of down elevator travel and 24-26 degrees of up travel. Once this has been achieved, you check the balance. You can balance by running a string down the elevator hinges or brace the canard upside down. Either way, without paint they shoul0d hang slightly nose down. With paint they should be level, but nose down is OK, all to reduce flutter. The string method seems more precise to me, and mine seem OK so far, but we’ll recheck after painting.
