Install the Aileron Servos and Pushrods
❏ ❏
1. Glue two 5/16" x 1/2" x 11/16" [8mm x 13mm x
18mm] hardwood blocks to the servo cover. Position
the blocks so the servo fits between the blocks.
❏ ❏
2. Drill a 1/16" [1.6mm] hole through the servo
cover into the center of the servo mounting blocks.
Install and then remove a #2 x 3/8" [10mm] wood
screw into the holes you drilled. Apply a drop of thin
CA into the holes to harden the threads. Once the glue
has cured, install the screws into the servo cover.
❏ ❏
3. Install a 12" [305mm] servo extension onto
the servo lead. Secure the extension to the lead with
tape, a piece of shrink tube or some other method to
keep them from coming unplugged.
❏ ❏
4. Place the servo onto the servo mounting
blocks. Drill through the servo mounting holes with a
1/16" [1.6mm] drill bit. Remove the servo from the
servo cover. Install and then remove a servo
mounting screw into each of the holes you have
drilled. Apply a drop of thin CA into the holes to
harden the threads. Once the glue has cured, install
the servo onto the servo cover using the hardware
included with your servo. Center the servo and then
install a servo arm as shown.
❏ ❏
5. Inside the servo bay a string is taped. Tie the
string to the servo extension. Pull the string and the
servo lead through the wing. Untie the string from the
lead and insert the lead through the small hole on the
top of the wing at the root. Tape the lead to the wing
to prevent it from falling back into the wing.
❏ ❏
6. Place the servo cover onto the wing. The
opening for the servo arm should be pointed
towards the wingtip. Drill a 1/16" [1.6mm] hole
Did you know… At the height of the Great
Depression, aircraft executive Walter H. Beech
and airplane designer T.A. “Ted” Wells joined forces
to collaborate on a project many considered
foolhardy—a large, powerful, and fast biplane built
specifically for the business executive. The Beech
Model 17, popularly known as the “Staggerwing,”
was first flown on November 4, 1932.
