Instruction Manual.

INTRODUCTION ank you for choosing the DECATHLON 60-85cc-3D ARTF by SG MODELS . e DECATHLON 60-85cc-3D was designed with the intermediate/advanced sport yer in mind. It is a semi scale airplane which is easy to y and quick to assemble. e 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 nd that most of the work has been done for you already. e motor mount has been tted and the hinges are pre-installed. Flying the DECATHLON 60-85cc-3D is simply a joy.
is instruction manual is designed to help you build a great ying aeroplane. Please read this manual throughly before starting assembly of your DECATHLON 60-85cc-3D Use the parts listing below to indentify 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 & REPONSIBILITY.
If you are inexperienced with basic R/C ight we strongly recommend you contact your R/C supplier and join your local R/C model Flying Club. R/C Model Flying Clubs o er a variety of training procedures designed to help the new pilot on his way to successful R/C ight.
ey will also be able to advise on any insurance and safety regulations that may apply.

Attach the ap linkage to the control horn. Slide the clevis retainer over the forks of the clevis. 5.

Adjust the linkage so the ap is in the mid- ap position. It may take a few tries to properly adjust the linkage. 8.

Attach the clevis to the ap servo arm.

ASSEMBLY

Trim and cut.

Using a modeling knife, carefully cut o the rear portion of one of the 3 nylon tubes leaving 1/2" protruding from the rear of the stopper. is will be the fuel pick up tube.

16

Using a modeling knife, cut one length of silicon fuel line. Connect one end of the line to the weighted fuel pick up and the other end to the nylon pick up tube. 1.
2.

With the stopper assembly in place, the weighted pick-up should rest away from the rear of the tank and move freely inside the tank. e top of the vent tube should rest just below the top of the tank. It should not touch the top of the tank. When satis ed with the alignment of the stopper assembly tighten the 3x20mm 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.

You should mark which tube is the vent and which is the fuel pickup when you attach fuel tubing to the tubes in the stopper. Once the tank is installed inside the fuselage, it may be di cult to determine which is which.
Slide the fuel tank into the fuselage. Guide the lines from the tank through the hole in the ewall.
2.

Carefully bend the second nylon tube up at a 45� angle. is tube is the vent tube. Test t the stopper assembly into the tank. It may be necessary to remove some of the ashing around the tank opening using a modeling knife. If ashing is present, make sure none falls into the tank.

Use a 2.5mm hex wrench to tighten the

screw that secures the throttle pushrod

wire. Make sure to use threadlock on the

screw so it does not vibrate loose.

APPLY THE DECALS
If all the decals are precut and ready to stick. Please be certain the model is clean and free from oily ngerprints and dust. Position decal on the model where desired, using the photos on the box and aid in their location. 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 ngerprints and dust. Position decal on the model where desired, using the photos on the box and aid in their location.
BAL ANCING 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 170MM BACK FROM THE LEADING EDGE OF THE WING AT THE WING ROOT. Mount the wing to the fuselage. Place a piece of masking tape on the top of each wing 170mm back from the leading edge at the wing root. With the model inverted, place your ngers on the masking tape and carefully li the plane. is is the point at which your model should balance for your rst ights. Later, you may wish to experiment by shi ing the balance up to 10mm forward or back to change the ying characteristics. Moving the balance forward may improve the smoothness and arrow- like tracking, but it may then require more speed for take o and make it more di cult to slow down for landing. Moving the balance a makes the model more agile with a lighter and snappier "feel". In any case, please start at the location we recommend.

*If possible, rst 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. With the wings attached to the fuselage, all parts of the model installed ( ready to
y), and empty fuel tanks, hold the model at the marked balance point with the stabilizer level. Li the model. If the tail drops when you li , the model is "tail heavy" and you must add weight* to the nose. If the nose drops, it is "nose heavy" and you must add weight* to the tail to balance. 1.

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 rst. Pull back on the elevator stick. e elevator halves should move up. If it they do not, ip 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. e rudder should move to the right. If it does not, ip 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, ip 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. e right aileron should move up and the other aileron should move down. If it does not, ip the servo reversing switch on your transmitter to change the direction.

PREFLIGHT CHECK 1) Completely charge your transmitter and receiver batteries before your rst day of ying. 2) Check every bolt and every glue joint in the DECATHLON 60-85cc-3D 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 rst few ights. 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.

We wish you many safe and enjoyable ights with your DECATHLON 60-85cc-3D .
