To avoid scratching your new airplane, do notunwrap the pieces until they are needed forassembly. Cover your workbench with an oldtowel or brown paper, both to protect the air-craft and to protect the table. Keep a couple ofjars or bowls handy to hold the small parts af-ter you open the bag.

Please trial fit all the parts. Make sure you havethe correct parts and that they fit and arealigned properly before gluing! This will assureproper assembly. ORBIT ARF is hand madefrom natural materials, every plane is uniqueand minor adjustments may have to be made.However, you should find the fit superior andassembly simple.The painted and plastic parts used in this kitare fuel proof. However, they are not tolerantof many harsh chemicals including the follow-ing: paint thinner, C/A glue accelerator, C/A gluedebonder and acetone.

Caution: this model is not a toy!If you are a beginner to this type of powered model, please ask an experienced model flyer for helpand support. If you attempt to operate the model without knowing what you are doing you couldeasily injure yourself or somebody else. Please keep your safety and well-being in mind at alltimes.Important: before you start constructionEven if you have already built a large number of RC models please read right through theseinstructions and check all the kit components against the parts list. We have taken great trouble tokeep construction as simple as possible, without making any compromises in the area of safety.Note regarding the film coveringMinor creases or bubbles may develop in the film covering due to major fluctuations in weatherconditions (temperature, humidity etc.); in rare cases you may even find a slight warp in acomponent. These minor faults are in the nature of film-covered built-up wooden structures, andcan easily be corrected using a heat gun, as commonly used for modelling.Creases: Blow warm air over the area and rub down with a soft cloth.Wing warp: Hold the panel twisted gently in the opposite direction to the warp, and apply

warm air to remove the creases from the covering.Caution! do not heat the film more than is absolutely necessary. If the air or the iron is too hot, thefilm may melt and holes may be formed.This model is highly pre-fabricated and can be built in avery short time. However, the work which you have to carry out is important and must be donecarefully. The model will only be strong and fly well if you complete your tasks competently - soplease work slowly and accurately.

When self-tapping screws have to be screwed into wood, apply a little white glue to preventthem shaking loose: just squirt white glue into the hole and fit the screw.

+ 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. + 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 spinningpropeller.

1. Plug the servo leads and the switchlead into the receiver. You may want to plugan aileron extension into the receiver to makeplugging in the aileron servo lead easierwhen you are installing the wing . Plug thebattery pack lead into the switch.

2. Wrap the receiver and battery pack inthe protective foam to protect them from vi-bration. Use a rubber band or masking tape tohold the foam in place.

Do not permanently secure the receiver andbattery until after balancing the model.

3. Position the battery pack and receiverbehind the fuel tank. Use two tie wraps to holdthe battery and receiver securely in place aspictures below

4. Using a 2mm drill bit, drill a hole throughthe side of the fuselage, near the receiver, forthe antenna to exit.

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.

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

See picture wing attach to fuselage.

WING ATTACHMENT.

Accurately mark the balance point on the topof the wing on both sides of the fuselage. Thebalance point is located 65mm 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 .

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

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 LOCATED65MM 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 65mm back fromthe leading edge, at the fuselage sides.

*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) 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.

Ailerons : 15mm up 15mm down

Elevator : 15mm up 15mm down

Rudder : 25mm right 25mm left

CONTROL THROWS.

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.
