Introduction

Thank you for choosing the Edge 540 V3, 77.5" wingspan 35-40cc ARTF by SG MODELS. The Edge 540 V3, 77.5" wingspan 35-40cc 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 Edge 540 V3, 77.5" wingspan 35-40cc 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 Edge 540 V3, 77.5" wingspan 35-40cc. Use the parts listing below to identify all parts.

Assembly Instructions

Install the Ailerons

  1. Step 1: Remove the ailerons from the wing and remove the hinges.
  2. Step 2: Use a small piece of rough sandpaper to scuff the hinges for better epoxy adhesion. Do this to all aileron hinges.

    Image Description: A hand is shown holding a piece of sandpaper and lightly sanding a small hinge piece.

  3. Step 3: Apply epoxy to each hinge where it will be inserted into the ailerons. Tip: Apply some petroleum jelly to the metal pin hinge area to keep epoxy from interfering with smooth operation of hinge.

    Image Description: A hand is applying epoxy to the hinge pins. A small tube labeled "Epoxy" is visible.

  4. Step 4: Insert all four hinges in the ailerons at this time. Make sure hinges move up and down in the right direction and not side to side! Be sure to test the aileron hinges once you insert them. Ensure that the hinge pockets line up, and that the hinges move freely before the epoxy dries.

    Image Description: A hand is inserting a hinge into a slot on the aileron. The aileron is shown with multiple hinge slots.

  5. Step 5: Apply epoxy into each of the holes in the ailerons using a spare piece of pushrod wire or toothpick. Make sure to use enough epoxy so it securely adheres the hinge to the surfaces. Do not use an excessive amount of epoxy when gluing the hinges so that it expels from the hinge area.

    Image Description: A toothpick is being used to apply epoxy into a hinge hole on the aileron. The aileron is positioned on a flat surface.

  6. Step 6: Check the fit of the aileron to the wing. The top of the ailerons will align to the top of the wing. Make sure movement is smooth and bind free. We prefer 30-minute epoxy to allow enough working time during the hinge installation.

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. 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. The top of the vent tube should rest just below the top of the tank. It should not touch the top of the tank. When satisfied with the alignment of the stopper assembly tighten the 3 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.

Apply the Decals

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.

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.

Balancing

An important part of preparing the aircraft for flight is properly balancing the model.

  1. Step 1: Attach the wing panels to the fuselage. Make sure to connect the leads from the aileron to the appropriate leads from the receiver. Make sure the leads are not exposed outside the fuselage before tightening the wing bolts. Your model should be flight-ready before balancing.

    Image Description: The wings are shown attached to the fuselage, with wires connected.

  2. Step 2: The recommended Center of Gravity (CG) location for your model is (95-110mm) back from the leading edge at the center of the wing.

    Image Description: A diagram shows the wing with a measurement of 95-110mm indicated from the leading edge.

  3. Step 3: When balancing your model, make sure it is assembled and ready for flight. Support the plane upright at the marks made on the wing with your fingers or a commercially available balancing stand. This is the correct balance point for your model.

    Image Description: The aircraft is shown supported at the balance point on its wing.

*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.

With the wings 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.

Control Throws

Lift the model. If the tail drops when you lift, 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.

    Image Description: The aircraft is shown being lifted by its wings to check its balance point, with a measurement of 95-110mm indicated.

Ailerons:

  • High Rate: Up: 90 mm, Down: 90 mm
  • Low Rate: Up: 50 mm, Down: 50 mm

Elevator:

  • High Rate: Up: 90 mm, Down: 90 mm
  • Low Rate: Up: 30 mm, Down: 30 mm

Rudder:

  • High Rate: Right: 100 mm, Left: 100 mm
  • Low Rate: Right: 60 mm, Left: 60 mm

Diagram Description: A schematic shows the horizontal stabilizer, fuselage, and wing with arrows indicating control surface movements and their corresponding ranges (e.g., Horizontal/Elevator: 30-90mm, Fuselage/Rudder: 60-100mm, Wing/Aileron: 50-90mm).

Flight Preparation

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

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 Edge 540 V3, 77.5" wingspan 35-40cc 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.
  8. Properly balance the propeller. An out of balance propeller will cause excessive vibration which could lead to engine and/or airframe failure.
