1) Install a 10 x 6 propeller onto your Magnum
XL .40ARNV engine. Tighten the prop nut to secure
the propeller in place.
q
2) Set the engine onto the hardwood motor
mount rails and rotate the propeller so it is horizontal.
To properly align the engine, use a ruler and measure
from the front of each fuselage side, to the back edge
of the propeller. The measurement on the left should
be 1/2”. The measurement on the right should be 3/8”.
See photo # 22 below.

If you're using an engine that has a crankcase
dimension wider than the width of the hardwood
mounting rails, you can remove equal amounts of
wood from the inside edge of each rail. Remove small
amounts at a time until your engine fits properly, but
be careful not to remove too much material. A cop-
ing saw, is best to use to do this with, but a sharp
modeling knife will work well also.
q
3) When satisfied with the alignment, hold the
engine firmly in place and use a pencil to mark the
locations of the four mounting holes onto the hard-
wood motor mount rails.
q
4) Remove the engine. Using a 1/8” drill bit,
drill the four mounting holes through the motor mount.
When drilling the holes, make sure you drill
them straight down and not at an angle.
q
5) Set the engine back in place and double check
that the holes in the engine mounting lugs line up with
the holes in the engine mount. Install the engine us-
ing four 3mm x 19mm machine screws, eight 3mm
flat washers and four 3mm nylon insert nuts. Tighten
the screws and nuts completely to secure the engine
in place.
q
6) If your engine is equipped with a rear needle
valve assembly, install that and the carburetor onto
your engine now. You will have to cut a slot in the
side of the fuselage to clear the needle valve. Use a
modeling knife to do this. See photo # 23 below.

1) The fuel tank assembly incudes 3 different
length aluminum tubes. Discard the shortest of the
three tubes. It will not be used.
The 50mm long tube is used for the fuel line
pickup and the 80mm long tube is used for the
vent/pressure line. The fuel line pickup goes to the
fuel nipple on the carburetor, or rear needle valve,
and the vent/pressure line goes to the pressure tap on
the muffler.
q
2) Using 220 grit sandpaper carefully smooth
each end of the two tubes. This will prevent the fuel
line from being accidentally cut when it is installed.
q
3) Push the two aluminum tubes through the rub-
ber stopper until 1/2” of each tube protrudes from the
