Q2BT11 21 August,
1981 MASS BALANCING ELEVATORS. In
preparation for testing on
turbocharged Revmasters and
possible A-65 thru C-85
installations, we have further
explored the very high speed area
of the Q2 operating envelope. We
have found that mass balancing the
elevators improves the ride
qualities at high speed. Therefore,
we are supplying to all builders
the drawings and hardware to mass
balance all Q2 elevators, and
recommend this before first flight.

ELEVATOR MASS BALANCING
..... Locate the two Q2CSA11 arms and the molded lead weights.
..... These elevator mass balance arms can be retrofitted to the elevator
control system even after the canard has been mounted to the fuselage.
This will allow a closer clearance with the fuselage sides and maximize
the available legroom. If the mass balance arms are installed prior to
mounting the canard, careful measurements must be made to assure
clearance with the fuselage sides.
..... Begin by attaching a molded lead weight to each Q2CSA11 as shown.
..... Next, remove the two bolts holding CS20 in position, and slide it
outboard through the CS14 phenolic bearing until a Q2CSA11 arm can be
slid onto the tube with the lead weight projecting forward. Reinstall the
bolts holding CS20 in position.
..... Then remove the three bolts securing Q2CSA8 and slip it inboard
until the second Q2CSA11 arm can be slid on the outboard end inward with
the lead weight projecting forward. Reinstall the bolts holding Q2CSA8 in
place.
..... Locate the Elevator Rigging template and jig the elevator in the
full trailing edge up position. With the elevator in this position, each
Q2CSA11 should be almost resting on the canard upper surface just inboard
of the fuselage. Note the piece of felt called out as a bumper stop. The
Q2CSA11's are located as far outboard as practical so as not to interfere
with pilot or passenger legroom. Verify that when the elevator is rotated
to full trailing edge down position, that the arc of each Q2CSA11 clears
the fuselage and all other components.
..... Finally, return the elevator to the full trailing edge up position
with each Q2CSA11 resting almost on the canard, and drill in the one AN3-
12A bolt per side to attach the Q2CSA11's to Q2CSA8 and CS20.
..... Leave the CS13 pitch control arm unattached from Q2CSA8, and remove
the two AN4-11A bolts attaching the universal joint to Q2CSA8 and CS20.
Remove the universal joint so that each elevator can rotate independently
of the other. Make sure that you have lubricated all of the bearing and
hinge points to reduce the system friction to a minimum. It is desirable
for each elevator to balance at 0 degrees to 2 degrees trailing edge up
with all painting and finishing complete. Remove lead, as necessary from
the molded lead weight until that position is reached. Each elevator
should rotate freely about the hinge points when given a slight nudge.
