3) Bolt your motor and mount onto the firewall.
Use thread
locking compound (not supplied) on all the bolt threads.
4) Additional holes are needed in the firewall to allow air to flow
back inside the fuselage to cool the battery and the ESC in flight.
We recommend drilling three new 3/8” dia. holes in the approximate
locations shown in this photo. These holes, in addition to the ones
already there for the nose gear pushrod and the glow motor
mounting, will provide adequate cooling air going into the fuselage.
5) The cooling air must have a place to exit the fuselage. Using a
sharp new blade in your hobby knife, cut a 1” x 3” opening in the
bottom of the fuselage, 16” behind the landing gear. After making
the opening, seal and toughen the edges of the bare balsa wood
with a coat of Thin CA glue or epoxy.
6) a) Solder the appropriate connector (not supplied) to the
battery leads of your ESC.
b) Pass the motor leads of the ESC through the bottom right
cooling hole you made in back in Step 4. Connect the leads to the
motor. Operate the motor and check the direction of rotation. If
you need to reverse the rotation, refer to the instructions that came
with the motor and ESC.
c) Mount your ESC inside the nose of the airplane, just behind
the firewall. Stick it to the fuselage bottom with a 1-1/2” long piece
of 3/4” wide “hook & loop” tape (not supplied).
NOTE: Hook-and-loop “tape” has either the hook or the loop on
only one side of the strip. The other side is sticky back.
7) Cut 3 small pieces of 3/4” wide hook-and-loop tape (not
supplied) and stick them on the battery compartment floor, where
shown in the following photo. Put a long strip of the mating tape
on the bottom of each of your battery packs. This will keep your
battery pack from shifing position in flight.
8) Cut two 9” long pieces of 3/4” wide hook-and-loop strap
material (not supplied).
Install the two straps in the battery
compartment as shown, running them through the slots in the
plywood floor. Anchor the straps to the backside of the plywood
with a few drops of glue. These straps will keep your battery pack
from falling out of the airplane.
NOTE: Hook-and-loop “strap” has the hook surface on one side of
the strip and the loop surface on the other side. You can overlap
the ends of the strip and stick them together, effectively creating a
strap to hold your battery pack securely in position.
9) Mount the cowling to the fuselage with the four M2.6 x 10mm
Screws provided. Note that four holes for the screws are already
in the cowling - two on each side. Tape the cowling in correct
position on the fuselage, using a low-tack tape. Use a 1/16" drill
bit to make a guide hole through one of the upper cowl mounting
holes and into the fuselage side. Install an M2.6 x 10mm Screw
into the drilled hole and screw it in place - do not over-tighten
the screw.
Recheck the overall fit of the cowl and make any
adjustments needed with tape to hold it in place. Then on the
opposite side of the fuselage, drill another 1/16" guide hole and
install a screw into that hole.
Repeat this process for the
remaining two cowl mounting holes. Remove the tape.
