INTRODUCTION.
Thank you for choosing the Arising Star ARTF by SEAGULL MODELS. The Arising Star was designed from the ground up with the beginner flyer in mind. It is a High-wing aeroplane which is easy to fly and quick to assemble. The airframe is conventionally built using balsa, plywood and veneer to make it stronger than the average ARTF, yet the design allows the aeroplane to be kept light. You will find that most of the work has been done for you already. The pushrods are pre-made to the correct lengths, the motor mount has been fitted and the hinges are pre-installed and pinned for security. Flying the Arising Star is simply a joy.
This instruction manual is designed to help you build a great flying aeroplane. Please read this manual thoroughly before starting assembly of your Arising Star. Use the parts listing below to identify all parts.
WARNING.
Please be aware that this aeroplane is not a toy and if assembled or used incorrectly it is capable of causing injury to people or property. WHEN YOU FLY THIS AEROPLANE YOU ASSUME ALL RISK & RESPONSIBILITY.
If you are inexperienced with basic R/C flight we strongly recommend you contact your R/C supplier and join your local R/C Model Flying Club.

NOTE:To avoid scratching your new aero-
plane we suggest that you cover your workbench with an old towel. Keep a couple of jars or bowls handy to hold the small parts after you open the bags.
Please trial fit all parts. Make sure you have the correct parts and that they fit and are aligned properly be­fore gluing! This will ensure proper assembly as the Arising Star is made from natural materials and minor adjustments may have to be made.
The paint and plastic parts used in this kit are fuel proof. However, they are not tolerant of many harsh chemi­cals including the following: paint thinner, cyano-acrylate glue accel­erator, cyanoacrylate glue de-bonder and acetone. Do not let these chemi­cals come in contact with the colours on the covering and the plastic parts.

2) Remove the brace when satisfied with its fit ineach wing half. Coat both sides of one half of the dihedral brace with 30 minute epoxy. Next, pour some epoxy into the dihedral box in one wing panel. Make sure you cover the top and bottom as well as the sides of the dihedral brace. Use enough epoxy to fill any gaps.
1) Test fit the wing tube into each wing half. The brace should slide in easily up to the centreline that you drew.If not, use 220 grit sandpaper with a sanding block and sand down the edges and ends of the brace until it fits properly.
WING ASSEMBLY.
NOTE: We highly recommend using 30
minute epoxy as it is stronger and provides more working time, allowing the builder to properly align the parts. Using fast cure epoxy when joining the wing halves could result in the glue drying before the wing halves are aligned properly which may result in failure of the wing centre section during flight.
3) Peel off the backing from the self adhe­sive covering strip. Apply the strip to the centre section of the wing starting from the bottom trailing edge. Wrap the strip all the way around the wing until it meets the trailing edge again. Trim off any excess strip.
Carefully slide the two wing halves together and firmly press them together, allowing the excess epoxy to run out. There should not be any gap in the wing halves. Use rubbing alcohol and a paper tower to clean up any excess epoxy.
Apply masking tape at the wing join to hold the wing halves together securely .

Arising Star. Instruction Manual.
4) Once the epoxy has cured, trial fit both wing halves together. The centre ribs should fit together flush with no gaps. If gaps do exist, use 220 grit sandpaper and sand down the high spots on the root ribs and the wing joiner until a proper fit is achieved. The correct amount of dihedral is ready-built into the wings. With one wing half laid flat on the table, the other wing tip should be off the table surface. If this needs to be adjusted, you may do so by sanding small amounts from the centre ribs or dihedral brace. 5) Carefully apply masking tape around the top and bottom edge of the root rib of each wing half to protect them from damage caused by epoxy.
1) Install the rubber grommets and brass collets onto the aileron servo. Test fit the servo into the aileron servo mount.
Because the size of servos differ, you
may need to adjust the size of the precut opening in the mount. The notch in the sides of the mount allow the servo lead to pass through.
2) Remove the aileron servo. Place the mount onto the wing, aligning the cutout in the mount with the cutout in the wing. The two notches in the mount should face the leading edge of the wing.
3) While holding the servo mount firmly in place, trace around it using a pen.
8) Peel off the backing from the self adhesive covering strip. Apply the strip to the center section of the wing starting from the bottom trailing edge. Wrap the strip all the way around the wing until it meets the trailing edge again. Trim off any excess strip.
6) Mix a generous amount of 30 minute epoxy. Coat the exposed half of the dihedral brace, and the remaining wing joiner box and both root ribs with epoxy. Slide the two wing halves together and carefully align them at the leading and trailing edges. Wipe away any excess epoxy using paper towels. Use mask­ing tape wrapped around the center section to hold the halves in place until the epoxy cures. 7) When the epoxy has cured, carefully remove the masking tape from the wing.

4) Remove the mount, and using a mod­eling knife, carefully remove the covering from inside the outline you drew.
5) Using 6 Minute Epoxy , glue the servo mount into place. Remove any excess epoxy using a paper towel and rubbing alcohol. Use pieces of masking tape to hold the tray in place until the epoxy fully cures.
INSTALLING THE AILERON SERVO.
Install the aileron servo into the servo mount, with the output shaft towards the lead­ing edge of the wing, using the wood screws provided with your radio system. Drill 1/16” pilot holes through the mount before installing the screws. This will prevent the wood from splitting.
1) Thread one nylon adjustable control horn onto each aileron torque rod. Thread the horns on until they are flush with the ends of the torque rods.
2) Thread one nylon clevis at least 5/16” onto each of the two threaded wires.
3) With the aileron servo centered, install the servo arm onto the servo. The arm should be installed so it is parallel with the trailing edge of the wing.

When the stopper assembly is installed in the tank, the top of the vent tube should rest just below the top surface of the tank. It should not touch the top of the tank.
5) Test fit the stopper assembly into the tank. It may be necessary to remove some of the flashing around the tank opening using a modeling knife. If flashing is present, make sure none falls into the tank.
6) With the stopper assembly in place, the weighted pickup should rest about 3/8” away from the rear of the tank and move freely inside the tank. The top of the vent tube should rest just below the top of the tank. It should not touch the top of the tank.
7) When satisfied with the alignment of the stopper assembly tighten the 3mm x 20mm machine screw until the rubber stopper ex­pands and seals the tank opening. Do not overtighten the assembly as this could cause the tank to split.
Use pieces off foam rubber to hold the tank in place. Be careful the tank or the foam doesn’t interfere with the pushrods. Cut the fuel line in the middle of the loop. Keep track of which one is for the fuel pick-up and which one is for the muffler pressure.
Blow through the tubes to make sure the lines have not become kinked during installation.

ALIGNING THE HORIZONT AL ST ABILIZER.
1) Using a ruler and a pen, locate the centerline of the horizontal stabilizer , at the trail­ing edge, and place a mark. Use a triangle and extend this mark, from back to front, across the top of the stabilizer. Also extend this mark down the back of the trailing edge of the stabilizer .
The top of the stabilizer does not have
the hinge pins exposed.
2) Using a modeling knife, carefully re­move the covering from over the vertical sta­bilizer mounting slot in the top of the fuselage.
3) Slide the stabilizer into place in the pre­cut slot in the rear of the fuselage. The stabi­lizer should be pushed firmly against the front of the slot.
INSTALLING THE SPINNER.
Install the spinner backplate, propeller and spinner cone. The spinner cone is held in place using two 3mm x 12mm wood screws.
The propeller should not touch any part of the spinner cone. If it does, use a sharp modeling knife and carefully trim away the spinner cone where the propeller comes in contact with it.

4) With the stabilizer held firmly in place, use a pen and draw lines onto the stabilizer where it and the fuselage sides meet. Do this on both the right and left sides and top and bottom of the stabilizer.
5) Remove the stabilizer. Using the lines you just drew as a guide, carefully remove the covering from between them using a model­ing knife.
When cutting through the covering to re-
move it, cut with only enough pressure to only cut through the covering itself. Cutting into the balsa structure may weaken it.
6) Using a modeling knife, carefully re­move the covering that overlaps the stabilizer mounting platform sides in the fuselage. Re­move the covering from both the top and the bottom of the platform sides.
7) When you are sure that everything is aligned correctly, mix up a generous amount of 30 Minute Epoxy. Apply a thin layer to the top and bottom of the stabilizer mounting area
8) After the epoxy has fully cured, re- move the masking tape or T -pins used to hold the stabilizer in place. Carefully inspect the glue joints. Use more epoxy to fill in any gaps that may exist that were not filled previously and clean up the excess using a paper towel and rubbing alcohol.
1) Slide the vertical stabilizer into the slot in the top of the fuselage. The bottom edge of the stabilizer should also be firmly pushed against the top of the horizontal stabilizer .

ATTACHMENT WING-FUSELAGE.
See pictures below:
BALANCING.
1) It is critical that your airplane be bal­anced correctly . Improper balance will cause your plane to lose control and crash. The cen­ter of gravity is located 2.5” to 3” back from the leading edge of the wing, at the fuselage sides. Balance the Arising Star with the fuel tank empty .
2) Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the bottom side of the wing 2.5” to 3” back from the leading edge, at the fuselage sides.
When balancing the airplane you may need to move the battery or receiver for-
ward or after to achieve proper balance.
4) Using a 1/16” drill bit, drill a hole through
the side of the fuselage, near the receiver, for the antenna to exit. Route the antenna out of the fuselage and secure it to the vertical stabi­lizer using a rubber band and a modified servo arm. See picture as below.
3) Place your fingers on the masking tape and carefully lift the plane.
4) If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage sides under the horizontal stabilizer . If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver for­ward orif this is not possible, stick weight onto the firewall or use a brass heavy hub spinner hub, similar to those offered by Harry Higley. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.

PREFLIGHT CHECK.
1) Completely charge your transmitter and receiver batteries before your first day of flying.
2) Check every bolt and every glue joint in the Arising Star to ensure that everything is tight and well bonded.
3) Double check the balance of the air­plane. Do this with the fuel tank empty.
4) Check the control surfaces. All should move in the correct direction and not bind in any way.
5) If your radio transmitter is equipped with dual rate switches double check that they are on the low rate setting for your first few flights.
6) Check to ensure the control surfaces are moving the proper amount for both low and high rate settings.
7) Check the receiver antenna. It should be fully extended and not coiled up inside the fuselage.
E) Check the throttle. Moving the throttle stick forward should open the carbu­retor barrel. If it does not, flip the servo re­versing switch on your transmitter to change the direction.
FLIGHT PREPARATION.
C) Check the elevator first. Pull back on the elevator stick. The elevator halves should move up. If it they do not, flip the servo reversing switch on your transmitter to change the direction.
D) Check the rudder. Looking from behind the airplane, move the rudder stick to the right. The rudder should move to the right. If it does not, flip the servo reversing switch on your transmitter to change the direction.
We wish you many safe and enjoy­able flights with your Arising Star.
8) Properly balance the propeller. An out of balance propeller will cause excessive vi­bration which could lead to engine and/or air­frame failure.
INITIAL FLYING/SPORT FLYING
Ailerons: 3/8” up 3/8” down Elevator: 3/8 ” up 3/8” down Rudder: 1/2” right 1/2” left
AEROBATIC FLYING
Ailerons: 1/2” up 1/2” down Elevator: 5/8” up 5/8” down Rudder: 1” right 1” left
Do not use the aerobatic settings for initial test flying or sport flying.
4) By moving the position of the adjust­able control horn out from the control surface, you will decrease the amount of throw of that control surface. Moving the adjustable con­trol horn toward the control surface will in­crease the amount of throw.
CONTROL THROWS.
2) Turn on the radio system, and with the trim tabs on the transmitter in neutral, center the control surfaces by making adjustments to the clevises or adjustable servo connectors. The servo arms should be centered also.
1) We highly recommend setting up the Arising Star using the control throws listed. We have listed control throws for both initial test flying/sport flying and aerobatic flying.
3) When the elevator, rudder and aileron control surfaces are centered, use a ruler and check the amount of the control throw in each surface. The control throws should be
measured at the widest point of each sur­face!
F) From behind the airplane, look at the aileron on the right wing half. Move the aileron stick to the right. The right aileron should move up and the other aileron should move down. If it does not, flip the servo re­versing switch on your transmitter to change the direction.
A) Check the operation and direction
of the elevator, rudder , ailerons and throttle.
B) Plug in your radio system per the manufacture’s instructions and turn every thing on.
