This instruction manual is designed to help you build a great flying aeroplane. Please read thismanual thoroughly before starting assembly of your LIBERTY 182 II. Use the parts listing below toidentify all parts.

WARNING.

Please be aware that this aeroplane is not a toy and if assembled or used incorrectly it iscapable of causing injury to people or property. WHEN YOU FLY THIS AEROPLANE YOUASSUME ALL RISK & RESPONSIBILITY.If you are inexperienced with basic R/C flight we strongly recommend you contact your R/C supplierand join your local R/C Model Flying Club. R/C Model Flying Clubs offer a variety of trainingprocedures designed to help the new pilot on his way to successful R/C flight. They will also be ableto advise on any insurance and safety regulations that may apply.

TOOLS & SUPPLIES NEEDED.

Thick cyanoacrylate glue.30 minute epoxy.5 minute epoxy.Hand or electric drill.Assorted drill bits.Modelling knife.Straight edge ruler.2mm ball driver.Phillips head screwdriver.220 grit sandpaper.90° square or builder’s triangle.Wire cutters.Masking tape & T-pins.Thread-lock.Paper towels.

Some more parts.

HARDWARE PACK

COWLING.Landing gear.....

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. LIBERTY 182 II 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 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. Do not let these chemi-cals come in contact with the colors on thecovering 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.

SAFETY PRECAUTION.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.

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.

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.

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.

2. Secure the switch in place using thetwo machine screws provided with the radiosystem.

INSTALLING THE SWITCH.

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.

INSTALLING THE RECEIVER AND BATTERY.

Do not permanently secure the receiverand battery until after balancing the model.

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

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

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.

Ailerons : 20mm up 20mm down

Elevator : 25mm up 25mm down

Rudder : 30mm right 30mm left

1. We highly recommend setting up a planeusing 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.

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.

*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.

CG70 MM

CONTROL THROWS.

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 LOCATED70MM BACK FROM THE LEADING EDGE OFTHE WING.

2) Mount the wing to the fuselage. Using acouple of pieces of masking tape, place themon the top side of the wing 70 mm 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 70mm 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 .
