Instruction Manual. SEAGULL FUNFLY 3D. INTRODUCTION. Thank you for choosing the SEAGULL FUNFLY 3D ARTF by SEAGULL MODELS COMPANY LTD. The SEAGULL FUNFLY 3D 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.

When that is aligned, hold the stabilizer in that position using T-pins or masking tape. Align the horizontal stabilizer with the wing. When viewed from the rear, the horizontal stabilizer should be level with the wing.
SEAGULL FUNFLY 3D. HINGING THE ELEVATOR. 1) Carefully remove the elevator from one of the fuselage panel. Note the position of the hinges. 2) Remove each hinge from the fuselage panel and elevator and place a T-pin in the center of each hinge. Slide each hinge into the elevator until the T-pin is snug against the elevator. This will help ensure an equal amount of hinge is on either side of the hinge line when the elevator is mounted to the fuselage . Instruction Manual.

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