MXS-R. Instruction Manual.

INTRODUCTION.

Thank you for choosing the MXS-R ARTF by SEAGULL MODELS. The MXS-R was designed with the intermediate/advanced sport flyer in mind. It is a semi scale airplane which is easy to fly and quick to assemble. The airframe is conventionally built using balsa, plywood 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 motor mount has been fitted and the hinges are pre-installed . Flying the MXS-R 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 MXS-R . 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. R/C Model Flying Clubs offer a variety of training procedures designed to help the new pilot on his way to successful R/C flight. They will also be able to advise on any insurance and safety regulations that may apply.

HINGING THE AILERONS .

Note:

 1) Carefully remove the aileron from one of the wing panels. Note the position of the hinges.

The control surfaces, including the ailerons, elevators, and rudder, are prehinged with hinges installed, but the hinges are not glued in place. It is imperative that you properly adhere the hinges in place per the steps that follow using a high-quality thin C/A glue.

 Computer radio with 5 servos.  Glow plug to suit engine.  Propeller to suit engine.  Protective foam rubber for radio

system.

 Silicone fuel line.

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.

 2) Remove each hinge from the wing panel

and aileron and place a T-pin in the center of each hinge. Slide each hinge into the aileron until the T-pin is snug against the aileron. This will help ensure an equal amount of hinge is on either side of the hinge line when the aileron is mounted to the wing panel.

Hinge.

 4)Deflect the aileron and completely saturate each hinge with thin C/A glue. The ailerons front surface should lightly contact the wing during this procedure. Ideally, when the hinges are glued in place, a 1/64” gap or less will be maintained throughout the lengh of the aileron to the wing panel hinge line.

Note:

The hinge is constructed of a special material that allows the C/A to wick or penetrate and distribute throughout the hinge, securely bonding it to the wood structure of the wing panel and aileron.

 5) Turn the wing panel over and deflect the aileron in the opposite direction from the opposite side. Apply thin C/A glue to each hinge, making sure that the C/A penetrates into both the aileron and wing panel.

 6) Using C/A remover/debonder and a paper towel, remove any excess C/A glue that may have accumulated on the wing or in the aileron hinge area.

 7) Repeat this process with the other wing panel, securely hinging the aileron in place.

 8) After both ailerons are securely hinged, firmly grasp the wing panel and aileron to make sure the hinges are securely glued and cannot be pulled out. Do this by carefully applying medium pressure, trying to separate the aileron from the wing panel. Use caution not to crush the wing structure.

Note:

Work the aileron up and down several times to “work in” the hinges and check for proper movement.

- Apply a bead of canopy glue around the inside edge of the canopy. Position the canopy onto the hatch. Use tape to hold the canopy secure until the glue fully cures.

5) Install the canopy and secure it with M2x6mm screws.

1) If all the decals are precut and ready to stick. Please be certain the model is clean and free from oily fingerprints and dust. Position decal on the model where desired, using the photos on the box and aid in their location.

2) If all the decals are not precut, please use scissors or a sharp hobby knife to cut the decals from the sheet. Please be certain the model is clean and free from oily fingerprints and dust. Position decal on the model where desired, using the photos on the box and aid in their location.

INSTALLING THE RECEIVER.

 1) Plug the five servo leads and the switch lead into the receiver. Plug the battery pack lead into the switch also.

 2) Wrap the receiver and battery pack in the protective foam rubber to protect them from vibration.

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 100 MM BACK FROM THE LEADING EDGE OF THE WING AT THE WING ROOT.



2) Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing the leading edge of the wing at the wing root.

 3) Turn the airplane upside down. Place

your fingers on the masking tape and carefully lift the plane .

Accurately mark the balance point on the top of the wing on both sides of the fuselage. The balance point is located the leading edge of the wing at the wing root. This is the balance point at which your model should balance for your first flights. Later, you may wish to experiment by shifting the balance up to 10mm forward or back to change the flying characteristics. Moving the balance forward may improve the smoothness and arrow- like tracking, but it may then require more speed for take off and make it more difficult to slow down for landing. Moving the balance aft makes the model more agile with a lighter and snappier ”feel”. In any case,please start at the location we recommend .

100 mm back from

Wing bolt.

With the wing attached to the fuselage, all parts of the model installed ( ready to fly), and empty fuel tanks, hold the model at the marked balance point with the stabilizer level.

Lift the model. If the tail drops when you lift, the model is “tail heavy” and you must add weigh* to the nose. If the nose drops, it is “nose heavy” and you must add weight* to the tail to balance.

*If possible, first attempt to balance the model by changing the position of the receiver battery and receiver. If you are unable to obtain good balance by doing so, then it will be necessary to add weight to the nose or tail to achieve the proper balance point.

CONTROL THROWS.

Ailerons: 15mm up 20mm down.

Elevator: 15mm up. 20mm down.

Rudder: 25mm left. 40mm right.

FLIGHT PREPARATION.

Check the operation and direction of the elevator, rudder, ailerons and throttle.

 A) Plug in your radio system per the manufacturer's instructions and turn everything on.

 B) 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.

 C) 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.

 D) 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.

 E) 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.

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 MXS-R 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.

We wish you many safe and enjoyable flights with your MXS-R.

 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.

 8) Properly balance the propeller. An out of balance propeller will cause excessive vibration which could lead to engine and/or airframe failure.
