Install the propeller adapter (included with your motor) onto your brushless
outrunner motor, following the procedures in your motor's user's guide.
q
Install the backplate mount (included with your motor) onto your brushless
outrunner motor, following the procedures in your motor's user's guide.
q
Install your motor to the motor mounting box, using four M3 x 16mm machine
screws, four M3 flat washers and four M3 blind nuts. Tighten the machine
screws firmly to draw the blind nuts into the back of the motor mounting box.

q
Temporarily install the propeller onto your motor.
q
To ensure that the cowling will line up properly with the crankshaft, the
back edge of the propeller (at the hub) should be 5" (127mm) in front of the
back edge of the motor mounting box. If the distance is shorter you will need
to install a shim behind the motor to space it to the correct distance.
q
Test-fit and glue the motor mounting box assembly onto the firewall, using
a generous amount of 5 minute epoxy.
+
The motor mounting box has no specific top or bottom. It can be installed
in either direction.

IMPORTANT
Two sets of motor mounting holes are predrilled through the motor mounting box, one set for a four-hole radial
backplate mount and one set for mounting directly into the back of the motor. If your motor or its backplate mount uses a different
mounting hole pattern, you will need to drill new mounting holes through the motor mounting box to match.

After the epoxy sets up, glue one piece of balsa triangle support between
each side of the motor mounting box and the firewall.

Glue one plywood filler block into each precut slot in the firewall.

This section details the installation of the Magnum XL .52RFS four-stroke engine. Installation of a two-stroke engine uses the same
techniques. Regardless of what type of engine you use, the engine should be mounted on its side.
q
Temporarily glue the two engine mounting beams to your engine's mounting
lugs, using a couple of drops of thick C/A.
IMPORTANT
The location of the engine is not important at this time. It's
more important that the beams are square to the mounting lugs.
IMPORTANT
You must install the plywood filler blocks as described in the procedure below. The plywood filler blocks will prevent
exhaust residue from getting inside the fuselage and, depending on the size of your engine, the mounting holes may be located right
next to, or even inside, the slots. Installing the filler blocks ensures that the engine mounting area will be strong enough.
