Instruction Manual

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 YAK 55 size 25cc-35cc 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 YAK 55 size 25cc-35cc 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.
