TOOLS AND SUPPLIES NEEDED
• Medium C/A glue
• 30 minute epoxy
• 6 minute epoxy
• Hand or electric drill
• Assorted drill bits
• Modeling knife
• Straight edge ruler
SUGGESTION
To avoid scratching your new airplane, do not unwrap
the pieces until they are needed for assembly. Cover
your workbench with an old towel or brown paper,
both to protect the aircraft and to protect the table.
Keep a couple of jars or bowls handy to hold the
small parts after you open the bag.
NOTE:
1. Please trial fit all the parts. Make sure you have
the correct parts and that they fit and are aligned
properly before gluing! This will assure proper
assembly. The EXTRA 300S is hand made from
natural materials, every plane is unique and
minor adjustments may have to be made.
However, you should find the fit superior and
assembly simple.
2. The painted and plastic parts used in this kit are
fuel proof. However, they are not tolerant of many
harsh chemicals including the following: paint
thinner, C/A glue accelerator, C/A glue debonder
and acetone. Do not let these chemicals come in
contact with the colors on the covering and the
plastic parts.
3. The EXTRA 300S will perform 3-D aerobatics
easily if you use the largest engines
recommended within the engine range. If you
setup your airplane to do 3D maneuvers, you
will need to be throttle conscious; that is,
never apply full throttle on straight and level
flying or in dives to prevent flutter.
SAFETY PRECAUTION:
• This is not a toy.
• Be sure that no other flyers are using your radio
frequency.
• Do not smoke near fuel.
• Store fuel in a cool, dry place, away from
children and pets.
• Wear safety glasses.
• The glow plug clip must be securely attached to
the glow plug.
• Do not flip the propeller with your fingers.
• Keep loose clothing and wires away from the propeller.
PREPARATIONS
Remove the tape and separate the ailerons
from the wing and the elevators from the stab.
Use a covering iron with a covering sock on
high heat to tighten the covering if necessary.
Apply pressure over sheeted areas to
thoroughly bond the covering to the wood.
• Do not start the engine if people are near. Do not
stand in line with the side of the propeller.
• Make engine adjustments from behind the propeller
only. Do not reach around the spinning propeller.
INSTALLING THE AILERONS
1. Drill a 2.4mm hole, 13mm deep in the center of
each hinge slot to allow the CA to “wick” in. Use
the modeling knife to clean out the slots.
2. Use the modeling knife to cut a strip of covering
from the hinge slots in the wing and aileron.
3. Locate the four CA hinge strip. Snip off the
corners so they go in easier.
