RYAN - Item code: BH72 .Instruction ManualThis instruction manual is designed to help you build a great flying aeroplane. Please read thismanual thoroughly before starting assembly of your RYAN. Use the parts listing below to identify allparts.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.PARTS LISTING.FUSELAGE ASSEMBLY (1) Fuselage.WING ASSEMBLY(1) Right wing half with pre-installedaileron.(1) Left wing half with pre-installedaileron.Tail section assembly(1) Vertical stabilizer with preinstalledrudder.(1) Horizontal stabilizer with preinstalledelevator halves.Some more parts.HARDWARE PACKCOWLING.Landing gear.....SUGGESTION.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 aircraftand to protect the table. Keep a couple ofjars or bowls handy to hold the small parts afteryou open the bag.NOTE.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. RYAN 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 following:paint thinner, C/A glue accelerator, C/A gluedebonder and acetone. Do not let these chemicalscome in contact with the colors on thecovering and the plastic parts.2

Connect oneend of the line to the weighted clunk and theother end to the nylon pick up tube in the stopper.Drill a hole6mm diameter. 3) Carefully bend the second nylon tubeup at a 45 degree angle (using a cigarettelighter). This tube will be the vent tube to themuffler. 4) Carefully bend the third nylon tube downat a 45 degree angle (using a cigarette lighter).This tube will be vent tube to the fueling valve.When the stopper assembly is installed in thetank, the top of the vent tube should rest justbelow the top surface of the tank. It should nottouch the top of the tank.13

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 permanentlyuntil after balancing the airplane. Youmay need to remove the tank to mount thebattery in the fuel tank compartmentVent tubeFuel pick- up tubeFuel fill tube 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 expandsand 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. 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.Fuel tank14

Position the battery pack and receiverbehind the fuel tank. Use two tie wraps tohold the battery and receiver securely in place.As pictures below.Do not permanently secure the receiverand battery until after balancing the model. 4.

RYAN - Item code: BH72 .Instruction ManualBALANCING. 1) It is critical that your airplane be balancedcorrectly. Improper balance will causeyour plane to lose control and crash.THE CENTER OF GRAVITY IS LOCATED100MM 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 100mm back fromthe leading edge, at the fuselage sides. 3. Turn the airplane upside down. Placeyour fingers on the masking tape and carefullylift the plane .Accurately mark the balance point on the topof the wing on both sides of the fuselage. Thebalance point is located 100mm back fromthe leading 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 locationwe recommend .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.*If possible, first attempt to balance the modelby changing the position of the receiver batteryand receiver. If you are unable to obtaingood balance by doing so, then it will be necessaryto add weight to the nose or tail toachieve the proper balance point.CONTROL THROWS. 1) We highly recommend setting up aplane using the control throws listed. 2) The control throws should be measuredat the widest point of each control surface. 3) Check to be sure the control surfacesmove in the correct directions.Ailerons : 15mm up 15mm downElevator : 12mm up 12mm downRudder : 30mm right 30mm leftAilerons ControlPRE-FLIGHT CHECK.151512123030 1) Completely charge your transmitter andreceiver batteries before your first day of flying. 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 enjoyableflights with your RYAN.32
