Balancing - Cub Crafters CC18-180 Maintenance Manual

3. BALANCING

(a) Insert a 0.25" diameter pin or bolt through each of the hinge holes of the elevator
(2 per elevator) such that about 0.25" of the pin or bolt protrude from either side
of the hinge.
(b) Place the elevator horizontally over a bench such that the exposed parts of the
pins or bolts rest on half tubes, knife-edges or a similar supports that have little
friction and allow the elevator to rotate freely (See Figure 27-40-2).
(c) Place a force gauge or scale at the trailing edge of the elevator, adjacent to the
FIRST rib, counting inboard to outboard. Ensure the elevator chord is level.
Record the weight.
(d) The weight at the trailing edge must be between 1.00 lb. and 1.40 lb. trailing
edge heavy.
If the elevator is not within these limits, contact Cub Crafters for disposition.
