Caution: this model is not a toy!If you are a beginner to this type of poweredmodel, please ask an experienced model flyerfor help and support. If you attempt to operatethe model without knowing what you are doingyou could easily injure yourself or somebodyelse. Please keep your safety and well-beingin mind at all times.

Important: before you start constructionEven if you have already built a large numberof RC models please read right through theseinstructions and check all the kit componentsagainst the parts list. We have taken greattrouble to keep construction as simple aspossible, without making any compromisesin the area of safety.

Note regarding the film coveringMinor creases or bubbles may develop in thefilm covering due to major fluctuations inweather conditions (temperature, humidityetc.); in rare cases you may even find a slightwarp in a component. These minor faults arein the nature of film-covered built-up woodenstructures, and can easily be corrected usinga heat gun, as commonly used for modelling.Creases: Blow warm air over the area

and rub down with a softcloth.

Wing warp: Hold the panel twistedgently in the oppositedirection to the warp, andapply warm air to removethe creases from thecovering.

Caution! do not heat the film more than isabsolutely necessary. If the air or the iron istoo hot, the film may melt and holes may beformed.

This model is highly pre-fabricated and canbe built in a very short time. However, the workwhich you have to carry out is important andmust be done carefully. The model will onlybe strong and fly well if you complete yourtasks competently - so please work slowlyand accurately.

When self-tapping screws have to bescrewed into wood, apply a little whiteglue to prevent them shaking loose: justsquirt white glue into the hole and fit thescrew.

+ This is not a toy + Be sure that no other flyers are using yourradio frequency. + Do not smoke near fuel + Store fuel in a cool, dry place, away fromchildren and pets. + Wear safety glasses. +The glow plug clip must be securely attachedto the glow plug. + Do not flip the propeller with your fingers. + Keep loose clothing and wires away fromthe propeller. + Do not start the engine if people are near.Do not stand in line with the side of the propel-ler. + Make engine adjustments from behind thepropeller only. Do not reach around the spin-ning propeller.

7) Using a modeling knife, cut 3 lengths offuel line 150mm long. Connect 2 lines to the 2vent tubes and 1 line to the fuel pickup tube inthe stopper.

5) Test fit the stopper assembly into thetank. It may be necessary to remove some ofthe flashing around the tank opening usinga modeling knife. If flashing is present, makesure none of it falls into the tank.

6) When satisfied with the alignment ofthe stopper assembly tighten the 3mm x 20mmmachine screw until the rubber stopper ex-pands and seals the tank opening. Do not overtighten the assembly as this could cause thetank to split.

8) Feed three lines through the fuel tankcompartment and through the pre-drilled holein the firewall. Pull the lines out from behindthe engine, while guiding the fuel tank intoplace. Push the fuel tank as far forward aspossible, the front of the tank should just abouttouch the back of the firewall.

Blow through one of the lines to ensure thefuel lines have not become kinked inside thefuel tank compartment. Air should flow througheasily.

1) The stopper has been pre-assembledat the factory.

2) Using a modeling knife, cut one lengthof silicon fuel line (the length of silicon fuel lineis calculated by how the weighted clunk shouldrest about 8mm away from the rear of the tankand move freely inside the tank). Connect oneend of the line to the weighted clunk and theother end to the nylon pick up tube in the stop-per.

6. After the epoxy has fully cured, removethe masking tape or T-pins used to hold thestabilizer in place and carefully inspect theglue joints. Use more epoxy to fill in anygaps that were not filled previously andclean up the excess using a paper towel andrubbing alcohol.

5. When you are sure that everything isaligned correctly, mix up a generous amountof 30 minute epoxy. Apply a thin layer to thetop and bottom of the stabilizer mounting areaand to the stabilizer mounting platform sidesin the fuselage. Slide the stabilizer in place andre-align. Double check all of your measure-ments one more time before the epoxy cures.Remove any excess epoxy using a papertowel and rubbing alcohol and hold the stabi-lizer in place with T-pins or masking tape.

4. Remove the stabilizer. Using the linesyou just drew as a guide, carefully remove thecovering from between them using a modelingknife. When cutting through the covering toremove it, cut with only enough pressureto only cut through the covering it’s self.Cutting into the balsa structure mayweaken it. This could lead to possible fail-ure during flight.

Remove covering

Check to mark sure the wing and stabi-lizer are paralell. If they are not, lightly sandthe opening in the fuselage for the stabilizeruntil the stabilizer is paralell to the wing.

With the wing attached to the fuselage, allparts of the model installed ( ready to fly), andempty fuel tanks, hold the model at themarked balance point with the stabilizer level.Lift the model. If the tail drops when youlift, the model is “tail heavy” and you mustadd weigh* to the nose. If the nose drops, itis “nose heavy” and you must add weight* tothe tail to balance.

Ailerons : 20mm up 7mm down Flap : 20mm down Elevator : 20mm up 20mm down Rudder : 20mm right 20mm left

1) We highly recommend setting up aplane using the control throws listed.

2) The control throws should be meas-ured at the widest point of each control sur-face.

3) Check to be sure the control surfacesmove in the correct directions.

CONTROL THROWS.

*If possible, first attempt to balance the modelby changing the position of the receiver bat-tery and receiver. If you are unable to obtaingood balance by doing so, then it will be nec-essary to add weight to the nose or tail toachieve the proper balance point.

1) It is critical that your airplane be bal-anced correctly. Improper balance will causeyour plane to lose control and crash.

THE CENTER OF GRAVITY IS LOCATED75MM BACK FROM THE LEADING EDGEOF THE WING.

2) Mount the wing to the fuselage. Using acouple of pieces of masking tape, place themon the top side of the wing 75mm back fromthe leading edge, at the fuselage sides.3. Turn the airplane upside down. Placeyour fingers on the masking tape and care-fully lift the plane .

BALANCING.

Accurately mark the balance point on the topof the wing on both sides of the fuselage. Thebalance point is located 75mm back from theleading edge. This is the balance point atwhich your model should balance for your firstflights. Later, you may wish to experiment byshifting the balance up to 10mm forward orback to change the flying characteristics.Moving the balance forward may improve thesmoothness and arrow- like tracking, but itmay then require more speed for take offand make it more difficult to slow down forlanding. Moving the balance aft makes themodel more agile with a lighter and snappier”feel”. In any case, please start at the loca-tion we recommend .

1) Completely charge your transmitter andreceiver batteries before your first day of fly-ing.

2) Check every bolt and every glue joint inyour plane to ensure that everything is tightand well bonded.

3) Double check the balance of theairplane.

4) Check the control surface.

5) Check the receiver antenna . It shouldbe fully extended and not coiled up inside thefuselage.

6) Properly balance the propeller.We wish you many safe and enjoy-

able flights with your BIRD DOG.
