2. Fit one pushrod into the elevator pushrod guide tube on
the left side of the fuselage.
❏
3. Cut the backing plate from the large control horn and set
it aside for now. Align the center of the control horn directly
over the arm of the elevator torque rod as shown in the sketch.
Make sure that the horn is also aligned fore and aft so that the
pushrod holes are directly over the hingeline. Using the horn
as a guide, mark the location of the mounting holes.
❏
4. Drill two 3/32" [2.4mm] holes completely through the
elevator.
❏
5. Install the control horn using the backing plate and two
2-56 x 1/2" [12.7mm] machine screws. Fit the clevis to the
outermost hole in the control horn.
❏
6. Clip the excess length of pushrod to allow you to work
with the elevator pushrod easily. Prepare a servo using a
standard arm so that the servo arm is 90° to the servo case.
Fit it to the servo tray so that the second hole outboard or
the hole that is 13/32" [10.3mm] outboard of the center of the
servo shaft is lined up with the pushrod. Use a 1/16" [1.6mm]
drill to drill two holes for the servo. Install the servo using
the screws that came with your servo. As before, harded the
threads in the wood with thin CA.
