To avoid scratching your new airplane, donot unwrap the pieces until they are neededfor assembly. Cover your workbench with anold towel or brown paper, both to protect theaircraft and to protect the table. Keep a cou-ple of jars or bowls handy to hold the smallparts after you open the bag.

Please trial fit all the parts. Make sure youhave the correct parts and that they fit and arealigned properly before gluing! This will assureproper assembly. SPEED AIR-40 ARF is handmade from natural materials, every plane isunique and minor adjustments may have tobe made. However, you should find the fit su-perior and assembly simple. The painted and plastic parts used in thiskit are fuel proof. However, they are not toler-ant of many harsh chemicals including the fol-lowing: paint thinner, C/A glue accelerator, C/A glue debonder and acetone. Do not let thesechemicals come in contact with the colors onthe covering and the plastic parts.

+ 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.

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.

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 slowly andaccurately.

When self-tapping screws have to bescrewed into wood, apply a little white glueto prevent them shaking loose: just squirtwhite glue into the hole and fit the screw.

Creases: Blow warm air over the areaand rub down with a softcloth.

SAFETY PRECAUTION.

Wing warp: Hold the panel twisted gentlyin the opposite direction tothe warp, and apply warmair to remove the creasesfrom the covering.

INSTALLING THE STOPPER ASSEMBLYo1) The stopper has been pre-assembled atthe factory.

2) Using a modeling knife, cut one length ofsilicon fuel line (the length of silicon fuel line iscalculated 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.

FUEL TANK.

Throttle wire.

When the stopper assembly is installedin the tank, the top of the vent tube shouldrest just below the top surface of the tank.It should not touch the top of the tank.

3) Carefully bend the second nylon tube up ata 45 degree angle (using a cigarette lighter).This tube will be the vent tube to the muffler.

4) Carefully bend the third nylon tube down ata 45 degree angle (using a cigarette lighter).This tube will be vent tube to the fueling valve.

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

6) When satisfied with the alignment of thestopper 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.

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.

Blow through one of the lines to ensurethe fuel lines have not become kinked insidethe fuel tank compartment. Air should flowthrough easily.

9) To secure the fuel tank in place, apply abead of silicon sealer to the forward area ofthe tank, where it exits the fuselage behind theengine mounting box and to the rear of the tankat the forward bulkhead.

Do not secure the tank into place perma-nently until after balancing the airplane.You may need to remove the tank to mountthe battery in the fuel tank compartment.

8) Feed three lines through the fuel tank com-partment and through the pre-drilled hole in thefirewall. Pull the lines out from behind the en-gine, while guiding the fuel tank into place. Pushthe fuel tank as far forward as possible, thefront of the tank should just about touch theback of the firewall.

o 2) Using a ruler and a pen, locate thecenterline of the horizontal stabilizer, at the trail-ing edge, and place a mark. Use a traingle andextend this mark, from back to front, acrossthe top of the stabilizer. Also extend this markdown the back of the trailing edge of the stabi-lizer. Then slide the horizontal stabilizerthe intothe fuselage.

1. Using a modeling knife, cut away the covering from the fuselage for the stabilizer and remove it.

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.

o 6) When you a 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 plat-form sides in the fuselage. Slide the stabilizerin place and realign. Double check all of yourmea-surements once more before the epoxycures. Hold the stabilizer in place with T-pinsor masking tape and remove any excess ep-oxy using a paper towel and rubbing alcohol.

When cutting through the covering to re-move it, cut with only enough pressure toonly cut through the covering itself. Cut-ting into the balsa structure may weakenit.

5. Using a modeling knife, carefully re-move the covering that overlaps the stabilizermounting platform sides in the fuselage. Re-move the covering from both the top and thebottom of the platform sides.

Epoxy glue.

o 7) After the epoxy has fully cured, removethe masking tape or T-pins used to hold thestabilizer in place. Carefully inspect the gluejoints. Use more epoxy to fill in any gaps thatmay exist that were not filled previously andclean up the excess using a paper towel andrubbing alcohol.

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 must addweigh* to the nose. If the nose drops, it is “noseheavy” and you must add weight* to the tail tobalance.

1 3. Turn the airplane upside down. Placeyour fingers on the masking tape and care-fully lift the plane .

BALANCING.

1 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 LOCATED73MM BACK FROM THE LEADING EDGE OFTHE WING.1 2) Mount the wing to the fuselage. Using acouple of pieces of masking tape, place themon the top side of the wing 73 mm back fromthe leading edge, at the fuselage sides.

Accurately mark the balance point on the topof the wing on both sides of the fuselage. Thebalance point is located 73mm back from theleading edge. This is the balance point at whichyour model should balance for your first flights.Later, you may wish to experiment by shiftingthe balance up to 10mm forward or back tochange the flying characteristics. Moving thebalance forward may improve the smooth-ness and arrow- like tracking, but it may thenrequire more speed for take off and make itmore difficult to slow down for landing. Movingthe balance aft makes the model more agilewith a lighter and snappier ”feel”. In any case,please start at the location we recommend .

See picture wing attach to fuselage.

Installing the fuselage hatch as same as pic-ture below.

*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.

o 1) We highly recommend setting up a planeusing the control throws listed.

o 2) The control throws should be measuredat the widest point of each control surface.

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

Ailerons : 15mm up 15mm down.

Elevator : 10mm up 10mm down.

Rudder : 15mm right 15mm left.

CONTROL THROWS.

Aileron Control

1010

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

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

o 3) Double check the balance of the airplane.

o 4) Check the control surface.

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

o 6) Properly balance the propeller.

We wish you many safe and enjoyableflights with your SPEED AIR - 40.
