q
Cut away the covering material from over the landing skid mounting slots in
the bottom of the wing, then test-fit and glue the landing skid firmly into place,
using a generous amount of thick C/A.
IMPORTANT
Make sure to cut away the covering material from over
the gluing surfaces to ensure a strong bond.
IMPORTANT
Two different types of motor are showed installed. The first type shown in step 2A is an outrunner motor that uses a
backplate mount and a bolt-on threaded propeller adapter. This type of motor requires using the two plywood spacer plates and four
18mm long machine screws to install. The second type shown in step 2B is an outrunner motor that uses a backplate mount and a
slide-on propeller adapter. This type of motor does not require any spacer plates and uses four12mm long machine screws to install.
Please follow the step that matches the motor type that you're using.
q
Install the propeller adapter and the backplate mount (both included with
your motor) onto your brushless outrunner motor, following the procedures in
your motor's user's guide.
q
Install your motor, using two plywood spacer plates, four M3 x 18mm
machine screws and four M3 flat washers, making sure to tighten the machine
screws firmly.
IMPORTANT
The two plywood spacer plates are provided to push
your motor out far enough so that the front of the propeller adapter is
approximately 1/16" (1.6mm) in front of the fuselage sides.
IMPORTANT
The preinstalled blind nuts in the firewall are spaced to fit a majority of 4-hole radial backplate mounts of motors
within the specifications of the aircraft. If your motor's backplate mount uses a different mounting hole pattern, you will need to drill new
mounting holes and reinstall the blind nuts to match.

q
When satisfied with the fit and alignment, hold the cowling securely in place,
using a couple of pieces of masking tape.
q
Drill two 1/16" (1.6mm) diameter pilot holes through each side of the
cowling for the wood screws. Position one pilot hole centred between the top
of the cowling and the top of the wing, and one pilot hole centred between the
bottom of the cowling and the bottom of the wing. All four pilot holes should be
1/8" (3mm) in front of the back edge of the cowling.
q
Slide the cowling onto the front of the aircraft and align it. When aligned
properly, the hole in the middle of the cowling should be centred around the
motor shaft and the back of the cowling should fit flush against the surface of
the aircraft. The cutouts in the side of the cowling should fit over the contour
of the wing leading edges, too.
IMPORTANT
You may need to cut a notch in the bottom of the cowling
to fit around the front of the landing skid.
q
Cut out the back of the cowling along its base, making sure to cut the back
edge straight.
q
Using the moulded scribe lines as a guide, cut out the sides of the cowling to
clear the wing leading edges, then cut out the holes in the front and the bottom
of the cowling for the propeller adapter and the three cooling intake holes.
IMPORTANT
Depending on the motor that you're using, you may need
to cut out more of the front of the cowling than shown.
q
Remove the cowling and apply a couple of drops of thin C/A into the four
pilot holes and allow the C/A to fully cure.
q
Install the cowling, using four M2 x 10mm washer-head wood screws.
q
Install your motor, using four M3 x 12mm machine screws and four M3 flat
washers, making sure to tighten the machine screws firmly.
IMPORTANT
It's not necessary to use the two plywood spacer plates
with this type of motor.
