Step 4: Rudder and elevator servo install
Installing these servos is relatively
straightforward as depicted in the image
to the right. Simply attach both servos in
place as shown using two woodscrews
each. Note that higher torque servos are
required here (MG90S will suffice). Drill
2mm pilot holes before securing. Attach
each pushrod to the appropriate servo
horn using a small metal clevis and
secure with a hex screw. After you have
confirmed the correct operation of each
servo and control surface, trim the
excess length off each pushrod.
Step 5: Main landing gear install
The main landing gear struts are
glued/screwed directly to the underside
of the main wings. Locate the reinforced
area in which these sit and cut a small
grove in the plywood into which the strut
will sit using a craft knife. Drill a 3mm
hole at the end of the grove closest to
the fuselage at 10mm depth. Secure the
strut in place with 30-minute epoxy and a
plastic strap. Finally, add a wheel and a
collar to the strut. Repeat for both sides.
Step 6: Nose landing gear install
Begin by assembling the nose landing
gear strut, wheel and collars as per the
image to the right.
