LASER 200 Instruction Manual INTRODUCTION Thank you for choosing the LASER 200 ARTF by SEAGULL MODELS. The LASER 200 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 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.
LASER 200 Instruction Manual NOTE: To avoid scratching your new aeroplane 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 LASER 200 is made from natural materials and minor adjustments may have to be made.
LASER 200 Instruction Manual HINGING THE AILERONS. Note: 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. 1) Carefully remove the aileron from one of the wing panels. Note the position of the hinges.

MOUNTING THE ENGINE. 1) Trial fit your engine on the motor mount. The engine should be positioned so there is ample clearance in the cowling for spinner backplate mounted to the prop drive shaft. 2) Marking 4 points on the motor mount.
LASER 200 Because of the size of the cowl, it may be necessary to use a needle valve extension for the high speed needle valve. Make this out of sufficient length 1.5mm wire and install it into the end of the needle valve. Secure the wire in place by tightening the set screw in the side of the needle valve. Instruction Manual 1.5mm wire ( needle valve). 2) While keeping the back edge of the cowl flush with the marks, align the front of the cowl with the crankshaft of the engine.
LASER 200 Instruction Manual ELEVATOR AND RUDDER SERVO INSTALLATION. We recommended to use long servos arm for all servos without throttle servo. 1) Locate and cut out the covering film from the servo holes in both sides of fuselage. INSTALLING THE SPINNER. Using spinner size 3” ( not include). Install the spinner backplate, propeller and spinner cone. The propeller should not touch any part of the spinner cone.
LASER 200 Instruction Manual 3) Slide the elevator on the horizontal stabilizer panel until there is only a slight gap. The hinge is now centered on the horizontal stabilizer panel and elevator. Remove the Tpins and snug the elevator against the horizontal stabilizer panel. A gap of 1/64” or less should be maintained between the horizontal stabilizer panel and elevator. C/A glue. 5) Turn the horizontal stabilizer panel over and deflect the elevator in the opposite direction from the opposite side.
LASER 200 Instruction Manual Remove covering. 2) Using a modeling knife, carefully remove the covering at mounting slot of horizontal stabilizer ( both side of fuselage). When cutting through the covering to remove it, cut with only enough pressure to only cut through the covering itself. Cutting into the balsa structure may weaken it. 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.
LASER 200 HINGING THE RUDDER. Hinging the rudder refer to hinging the aileron and elevator.
