o 5 . If you are using a glow engine, an additional cooling
hole for the cylinder head is recommended . Cut out a 3/8"
[9 .5mm] wide hole .
o 6 . Use four #2 x 3/8" [9 .5mm] sheet-metal screws with
four #2 flat washers to attach the cowl . Depending on your
particular engine, you may need to install the muffler and
needle valve extension before the cowl is installed . In our
case, we needed to install the cowl first . Don’t forget to hook
up your fuel lines correctly .
Propeller & Spinner Installation
o 1 . Fit the spinner backplate to the engine . Use a prop
reamer to enlarge the hole if necessary . Install the propeller
recommended for your engine, making sure to align the prop
correctly on the spinner backplate so that the spinner cone
fits without touching the cone . Use the prop washer that
came with your engine / motor . Install the prop nut and any
lock nut included with your engine securely .
o 2 . Test fit the spinner cone to the backplate . Trim the blade
openings in the cone at any points that interfere with the
propeller . Attach the cone to the backplate using the screws
supplied with the spinner .
Important: The cone must not
touch the propeller .
Pilot Installation (Optional)
A pilot is not included with this ARF but we have made
provisions for you to install one if you wish . The Great Planes
1/5
th scale Civilian Pilot fits well and can be ordered in red
(GPMQ9062), blue (GPMQ9063), or yellow (GPMQ9064) .
o 1 . If you are going to install a pilot figure, you’ll have to
modify the figure to make it fit the cockpit . The Great Planes
1/5
th scale Civilian Pilot shown is fairly tall and needs to be
cut down to fit properly . Cut the figure using a hobby knife
or hobby saw just below the harness buckles . Use a belt
sander or a sanding bar to sand the base of the figure so
that it is flat .
