fuselage. Attach the motor to the fuselage using two 3mm x
10mm machine screws and 3mm washers.
2. Cut a 7/16" x 1/4" [11mm x 6mm] hole for the speed
control on/off switch in the side of the fuselage,
approximately 5" [127mm] from the front of the fuselage. We
suggest first drawing the rectangle on the side of the
fuselage. Then, use a 3/32" [2.3mm] drill bit to drill a hole in
each corner of the rectangle.
3. Use a sharp hobby knife to cut the remainder of the
rectangle.
4. Drill a 1/4" [6mm] hole, 3/4" [19mm] forward of the
on/off rectangle. Test fit the motor button in the hole from the
outside to check the fit. You may need to enlarge the hole
slightly with a hobby knife.
5. Remove the nut and split washer from the motor button
and install the button from the inside. Secure the button to
the fuselage with the split washer and nut. Insert the on/off
switch, end first, from the inside, through the hole in the
fuselage. Carefully pull the switch through the hole, making
sure not to damage the wires. Secure the switch to the
fuselage with two #2 x 3/8" sheet metal screws.
6. Plug the electronic speed control into the motor. The
red wire from the speed control must plug into the red wire
from the motor and the black into the black. Check that the
insulation covers the metal connectors on both plugs. If it
does not, use electrical tape to insulate the plugs to prevent
them from shorting.
7. From the hook and loop material, cut a 1-1/2" [38mm]
long piece of both material. Clean the back of the electronic
speed control with a paper towel dampened with rubbing
alcohol. Glue the soft material to the back of the electronic
speed control with CA. Glue the rough material to the inside
of the fuselage, opposite the on/off switch. Attach the
electronic speed control to the side of the fuselage.
Install the Elevator
1. Temporarily attach the elevator to the stab with four CA
hinges. Do not glue the hinges. Thread a nylon clevis onto
the elevator pushrod, 14 turns, and slide a silicone clevis
retainer over the clevis. Attach the clevis in the third hole
from the bottom of a small control horn and insert the
pushrod in the outer pushrod tube, in the fuselage.
2. Align the clevis attachment holes with the leading edge
of the elevator and center the control horn on the aft end of
the fuselage. Mark on the elevator the location of the two
control horn mounting holes.
