❏❏5. Notice the correct locations of the aileron and
flap servos on the inside of the hatches (indicated by the dashed lines). Refer to these photos when mounting the servos to the hatches in the following steps.
Now it’s time to mount the servos to the hatch
covers. Start with the left aileron servo.
Refer to this photo for the following seven steps.
❏❏6. Make a one-arm servo arm by cutting off the
unused arms. (The outer hole in the servo arm must be at least 3/4" [19mm] from the center of the output shaft.)
❏❏7. Place the servo on the aileron hatch cover as shown, then place the arm on the servo (remember, this is for the left aileron). ❏❏8. Take the servo off the hatch cover. Position two
3/8" x 13/16" x 13/16" [10 x 20 x 20mm] hardwood servo mounting blocks on the servo (one of the blocks may have to be trimmed to accommodate the servo wire where it comes out of the servo). The wood grain in the blocks runs vertically.
❏❏9. Place a piece of thin cardstock (such as from the header card that some servos are packaged on) under the servo and between each mounting block and the servo. Later, the cardstock will be removed, thus providing adequate spacing for vibration isolation. ❏❏10. Drill 1/16" [1.6mm] holes through the blocks
for the mounting screws. Mount the servo to the
blocks with the screws that came with the servo. Remove the cardstock spacers.
❏❏11. Mount the left flap servo to two more
mounting blocks the same way.
❏❏12. Mix some 30-minute epoxy for gluing the
mounting blocks to the hatch covers. Smear a thin coat of epoxy on the inside of the hatch covers in the area where the mounting blocks will be glued. Thoroughly coat the ends of the blocks that contact the covers.Wait a few minutes for the mounting blocks to absorb the epoxy, then recoat with the epoxy. Position the servos with the mounting blocks on the covers so the servo arms are centered in the openings. Use clamps or weights to hold the mounting blocks to the hatch covers until the epoxy hardens.
❏❏13. After the epoxy has fully hardened,
temporarily remove the servos from the mounting blocks. Add a few drops of thin CA to the screw holes and allow to fully harden. Remount the servos to the blocks with the screws.
