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.
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 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.
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.
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.
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.
q Install the backplate mount (included with your motor) onto your brushless
outrunner motor, following the procedures in your motor's user's guide.
