‰
Locate the elevator mount parts, elevator
mount, EF, ER and the retract assembly
plate.
Note: There are two sets of parts.
‰
On each of the EF and ER parts, remove the
lower half (from the hole center to the
rounded tip) and remove 1/8” of material from
the flat side.
Note: The completed servo
mount will be epoxied onto the retract
assembly plate, the 1/8” slot is to create an
offset to account for the thickness of the
retract assembly plate.
‰
Key the parts, EF and ER into the appropriate
slots and glue vertically to the sides of the
elevator mount as shown using 5-minute
epoxy.
‰
Mount the servo into the servo mount and
test fit the servo mount assembly onto the
retract assembly plate. The servos should be
located as rearward as possible on the plate
allowing space for access to the retract plate
mounting screws (see section 6.2.3) with the
servo arms rearward also.
Note: Depending
on the servo used, removal of some material
may be required. A 70 in-oz torque servo
was used for each elevator on the prototype
model.
‰
When satisfied with the location and fit,
remove the servo and glue the servo
mounting plates in place onto the retract
mounting plate.
‰
Install the elevator servos. Note: Use Dubro
heavy duty servo arms on elevator.
IMPORTANT!
Before proceeding with the next steps, it is recommended that section 6.2.3 be completed first; at
minimum the retract actuator should be installed onto the retract assembly plate (step 21). The
installation continues on the following page.
