Elevator Balancing

It is critical that the control surfaces be properly configured for flight, so I'm summarizing some of the more important details from different areas of the manual here.

You will note that in the assembly of the elevator - canard hinges, (Figure 14-2) there are 2 washers, one on each side of the elevator mounted hinge. The hinge arm, mounted to the canard, connects to the hinge on the side where the bushing protrudes from the hinge. When installing the assembly, tighten the hinge screw until it is snug, then back it off one-half turn. Lock it in place with the appropriate locknut. It helps to lubricate the screw with some white grease. Once assembled, check the system for binding and full travel.

Full elevator deflection results in at least 26 degree trailing edge down elevator travel and 23 degree trailing edge up elevator travel. Verify that the keel cutout does not limit travel. We use the cutout in the keel as a control stop so you want to make sure that when you reach your control travel limits your stick hits the edge of the cutout. This will keep a pilot from putting stress on the control system
