7. Cut the bottom of the cowl as shown to provide exhaust
air to properly cool the engine. This step is required for both
a glow installation and the installation of an electric motor
and ESC.
❏
8. Install the spinner and propeller appropriate for your
engine. Make any cut outs required for access to the glow
plug, needle valve, etc. If you choose to make a hole in the
side of the cowl for access to the glow plug, you will have to
use a long neck glow starter. Standard length glow starters
are too short to reach through the cowl cheek. You may wish
to install a remote glow starter as we did to eliminate the
need for a hole for the glow starter.

Apply the Decals

1. Use the box photos as your guide for the installation of
the decals.
2. Use scissors or a sharp hobby knife to cut the decals from
the sheet.
3. Be certain the model is clean and free from oily fingerprints
and dust. Prepare a dishpan or small bucket with a mixture of
liquid dish soap and warm water–about one teaspoon of soap
per gallon of water. Submerse the decal in the soap and water
and peel off the paper backing. Note: Even though the decals
have a "sticky-back" and are not the water transfer type,
submersing them in soap and water allows accurate
positioning and reduces air bubbles underneath.
4. Position decal on the model where desired. Holding the
decal down, use a paper towel to wipe most of the water away.
5. Use a piece of soft balsa or something similar to
squeegee remaining water from under the decal. Apply the
rest of the decals the same way.

Check the Control Directions

❏
1. Turn on the transmitter and receiver and center the
trims. If necessary, remove the servo arms from the servos
and reposition them so they are centered. Reinstall the
screws that hold on the servo arms.
❏
2. With the transmitter and receiver still on, check all the
control surfaces to see if they are centered. If necessary, adjust
the clevises on the pushrods to center the control surfaces.
❏
3. Make certain that the control surfaces and the
carburetor respond in the correct direction as shown in the
diagram. If any of the controls respond in the wrong
direction, use the servo reversing in the transmitter to
reverse the throttle and ESC servos connected to those
controls. Be certain the control surfaces have remained
centered. Adjust if necessary. Note: For electric motor
installation hookup the ESC for throttle control.

Set the Control Throws

Use a Great Planes AccuThrow
measure and set the control throw of each control surface as
indicated in the chart that follows. If your radio does not have
dual rates, we recommend setting the throws at the low
rate setting.
Note: The throws are measured at the widest part of the
elevators, rudder and ailerons.
