4)Deflect the aileron and completelysaturate each hinge with thin C/A glue. Theailerons front surface should lightly contact thewing during this procedure. Ideally, when thehinges are glued in place, a 1/64” gap or lesswill be maintained throughout the lengh of theaileron to the wing panel hinge line.

Note:

The control surfaces, including theailerons, elevators, and rudder, areprehinged with hinges installed, but thehinges are not glued in place. It isimperative that you properly adhere thehinges in place per the steps that followusing a high-quality thin C/A glue.

1) Carefully remove the aileron from oneof the wing panels. Note the position of thehinges.

2) Remove each hinge from the wing paneland aileron and place a T-pin in the center ofeach hinge. Slide each hinge into the aileronuntil the T-pin is snug against the aileron. Thiswill help ensure an equal amount of hinge ison either side of the hinge line when the aileronis mounted to the wing panel.

HINGING THE AILERONS.

Note:

The hinge is constructed of a specialmaterial that allows the C/A to wick orpenetrate and distribute throughout thehinge, securely bonding it to the woodstructure of the wing panel and aileron.

3) Slide the aileron on the wing panel untilthere is only a slight gap. The hinge is nowcentered on the wing panel and aileron.Remove the T-pins and snug the aileronagainst the wing panel. A gap of 1/64” or lessshould be maintained between the wing paneland aileron.

5) Turn the wing panel over and deflect theaileron in the opposite direction from theopposite side. Apply thin C/A glue to eachhinge, making sure that the C/A penetrates intoboth the aileron and wing panel.

6) Using C/A remover/debonder and apaper towel, remove any excess C/A glue thatmay have accumulated on the wing or in theaileron hinge area.

Using a small weight (Weighted fuel pick-upworks well) and thread, feed the string throughthe wing as indicated.

INSTALLING THE AILERON SERVOS.

Attach servo lead to the aileron servo. Attachthe string to the servo lead and carefully threadit though the wing. Once you have thread thelead throught the wing, remove the string so itcan use for the other servo lead. Tape the servolead to the wing to prevent it from falling backinto the wing.

2) Install the aileron servo mount into thewing, with the output shaft towards the lead-ing edge of the wing.

8) After both ailerons are securely hinged,firmly grasp the wing panel and aileron tomake sure the hinges are securely glued andcannot be pulled out. Do this by carefullyapplying medium pressure, trying to separatethe aileron from the wing panel. Use cautionnot to crush the wing structure.

Note: Work the aileron up and down severaltimes to “work in” the hinges and checkfor proper movement.

7) Repeat this process with the other wingpanel, securely hinging the aileron in place.

1) Install the rubber grommets and brasscollets onto the aileron servo. Test fit the servointo the aileron servo mount.

Because the size of servos differ,you may need to adjust the size of the

precut opening in the mount. The notchin the sides of the mount allow the servolead to pass through.

We recommended to use long ser-vos arm for all servos without throttle

servo.

AILERON LINKAGE.

INSTALLING THE AILERON LINKAGE.

1) Using a ruler & pen to draw a straightline as below picture.

2) Locate the two nylon control horns, twonylon control horn backplates and six machinescrews.

3) Position the aileron horn on the bottomside of aileron. The clevis attachment holesshould be positioned over the hinge line.

4) Using a 1mm drill bit and the controlhorns as a guide, drill the mounting holesthrough the aileron halves.

6) Thread one nylon adjustable control hornonto each aileron control rod. Thread thehorns on until they are flush with the ends ofthe control rods.

5) Mount the control horns by inserting thescrews through the control horn bases andaileron halves, then into the mountingbackplates. Do Not overtighten the screws orthe backplates may crush the wood.

FUEL TANK.

INSTALLING THE STOPPER ASSEMBLY.

1) Using a modeling knife, carefully cutoff the rear portion of one of the 3 nylon tubesleaving 1/2” protruding from the rear of thestopper. This will be the fuel pick up tube.

2) Using a modeling knife, cut one lengthof silicon fuel line. Connect one end of theline to the weighted fuel pickup and the otherend to the nylon pick up tube.

3) Carefully bend the second nylon tubeup at a 45º angle. This tube is the vent tube.

ENGINE MOUNT.

Mark and drill 4 holes for engine mount.

9


Carefully use a lighter or heat gun topermenently set the angle of the vent tube.

Important: When the stopper assembly is in-stalled in the tank, the top of the vent tubeshould rest just below the top surface of thetank. It should not touch the top of the tank.

4) Test fit the stopper assembly into thetank. It may be necessary to remove some ofthe flashing around the tank opening using amodeling knife. If flashing is present, makesure none falls into the tank.

5) With the stopper assembly in place,the weighted pickup should rest away fromthe rear of the tank and move freely inside thetank. The top of the vent tube should rest justbelow the top of the tank. It should not touchthe top of the tank.

6) When satisfied with the alignment ofthe stopper assembly tighten the 3mm x 20mmmachine screw until the rubber stopper ex-pands and seals the tank opening. Do notovertighten the assembly as this could causethe tank to split.

Attach the silicone fuel and pressure pipes tothe tank. The lower pipe is the ‘feed’ and theupper two the ‘pressure and fill’. The fill pipeis the next pipe.

Slide the tank into the fuselage from inside sothat the neck is at the top of the fuselage andit locates through the engine bulkhead. Gentlysecure it to the top horizontal former with acable tie.

You should mark which tube is the ventand 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 difficult to determine which is which.

Blow through one of the lines to ensurethe fuel lines have not become kinked in-

side the fuel tank compartment. Air should flowthrough easily.

INSTALLING THE MAIN LANDING GEAR.

1) The blind nuts for securing the landinggear are already mounted inside the fuselage.

2) Using the hardware provided, mountthe main landing gear to the fuselage.

1.5mm wire( needle valve).

2) While keeping the back edge of thecowl flush with the marks, align the front ofthe cowl with the crankshaft of the engine. Thefront of the cowl should be positioned so thecrankshaft is in nearly the middle of the cowlopening. Use the spinner backplate as a guide.Hold the cowl firmly in place using pieces ofmasking tape.

Because of the size of the cowl, it may be nec-essary to use a needle valve extension for thehigh speed needle valve. Make this out of suf-ficient length 1.5mm wire and install it into theend of the needle valve. Secure the wire inplace by tightening the set screw in the side ofthe needle valve.

3) Install the muffler and muffler extensiononto the engine and make the cutout in thecowl for muffler clearance. Connect the fueland pressure lines to the carburetor, mufflerand fuel filler valve. Secure the cowl to fuse-lage using the 3mmx12mm screws (4).

The propeller should not touch any partof the spinner cone. If it does, use a

sharp modeling knife and carefully trim awaythe spinner cone where the propeller comesin contact with it.

ELEVATOR AND RUDDER SERVOINSTALLATION.

1) Locate and cut out the covering filmfrom the servo holes in both sides of fuselage.

2) Install the rubber grommets and brasscollets onto the aileron servo. Test fit the servointo the aileron servo mount.

Because the size of servos differ, you mayneed to adjust the size of the precut openingin the mount. The notch in the sides of themount allow the servo lead to pass through.

1) Carefully remove the elevator from oneof the horizontal stabilizer panels. Note theposition of the hinges.

2) Remove each hinge from the horizontalstabilizer panel and elevator and place a T-pinin the center of each hinge. Slide each hingeinto the elevator until the T-pin is snug againstthe elevator. This will help ensure an equalamount of hinge is on either side of the hingeline when the elevator is mounted to thehorizontal stabilizer panel.

HORIZONTAL STABILIZER.

1) Using a ruler and a pen, locate thecenterline of the horizontal stabilizer, at thetrailing edge, and place a mark. Use a tri-angle and extend this mark, from back to front,across the top of the stabilizer. Also extendthis mark down the back of the trailing edgeof the stabilizer.

Center line.

6) Using C/A remover/debonder and apaper towel, remove any excess C/A glue thatmay have accumulated on the horizontalstabilizer or in the elevator hinge area.

8) After both horizontal stabilizer aresecurely hinged, firmly grasp the horizontalstabilizer panel and elevator to make sure thehinges are securely glued and cannot be pulledout. Do this by carefully applying mediumpressure, trying to separate the elevator fromthe horizontal stabilizer panel. Use caution notto crush the horizontal stabilizer structure.

7) Repeat this process with the otherhorizontal stabilizer panel, securely hinging theelevator in place.

5) Turn the horizontal stabilizer panel overand deflect the elevator in the oppositedirection from the opposite side. Apply thin C/A glue to each hinge, making sure that the C/Apenetrates into both the elevator and horizontalstabilizer panel.

3) Slide the elevator on the horizontalstabilizer panel until there is only a slight gap.The hinge is now centered on the horizontalstabilizer panel and elevator. Remove the T-pins and snug the elevator against thehorizontal stabilizer panel. A gap of 1/64” orless should be maintained between thehorizontal stabilizer panel and elevator.

The hinge is constructed of a specialmaterial that allows the C/A to wick orpenetrate and distribute throughout thehinge, securely bonding it to the woodstructure of the horizontal stabilizerpanel and elevator.

4)Deflect the elevator and completelysaturate each hinge with thin C/A glue. Theelevators front surface should lightly contactthe horizontal stabilizer during this procedure.Ideally, when the hinges are glued in place, a1/64” gap or less will be maintained throughoutthe lengh of the elevator to the horizontalstabilizer panel hinge line.

8) After the epoxy has fully cured, re-move the masking tape or T-pins used to holdthe stabilizer in place. Carefully inspect theglue joints. Use more epoxy to fill in any gapsthat may exist that were not filled previouslyand clean up the excess using a paper toweland rubbing alcohol.

2) Using a modeling knife, carefully re-move the covering at mounting slot of hori-zontal stabilizer ( both side of fuselage).

3) Slide the stabilizer into place in the pre-cut slot in the rear of the fuselage. The stabi-lizer should be pushed firmly against the frontof the slot.

4) With the stabilizer held firmly in place,use a pen and draw lines onto the stabilizerwhere it and the fuselage sides meet. Do thison both the right and left sides and top andbottom of the stabilizer.

5) Remove the stabilizer. Using the linesyou just drew as a guide, carefully remove thecovering from between them using a model-ing knife.

6) Using a modeling knife, carefully re-move the covering that overlaps the stabilizermounting platform sides in the fuselage. Re-move the covering from both the top and thebottom of the platform sides.

When cutting through the covering to re-move it, cut with only enough pressure to

only cut through the covering itself. Cuttinginto the balsa structure may weaken it.

7) When you are sure that everything isaligned correctly, mix up a generous amountof 30 Minute Epoxy. Apply a thin layer to thetop and bottom of the stabilizer mounting areaand to the stabilizer mounting platform sidesin the fuselage. Slide the stabilizer in placeand realign. Double check all of your mea-surements once more before the epoxy cures.Hold the stabilizer in place with T-pins or mask-ing tape and remove any excess epoxy usinga paper towel and rubbing alcohol.

3) While holding the vertical stabilizerfirmly in place, use a pen and draw a line oneach side of the vertical stabilizer where itmeets the top of the fuselage.

2) Slide the vertical stabilizer into the slotin the top of the fuselage. The rear edge ofthe stabilizer should be flush with the rearedge of the fuselage and the lower rudderhinge should engage the precut hinge slot inthe lower fuselage. The bottom edge of thestabilizer should also be firmly pushed againstthe top of the horizontal stabilizer.

VERTICAL STABILIZERINSTALLATION.

1) Using a modeling knife, remove thecovering from over the precut hinge slot cutinto the lower rear portion of the fuselage. Thisslot accepts the lower rudder hinge.

7) Turn the fuselage panel over and deflectthe vertical stabilizer in the opposite directionfrom the opposite side. Apply thin C/A glue toeach hinge, making sure that the C/Apenetrates into thevertical stabilizer andfuselage panel.

8) Using C/A remover/debonder and apaper towel, remove any excess C/A glue thatmay have accumulated on the fuselage or inthe vertical stabilizer hinge area.

Work the rudder left and right severaltimes to “work in” the hinges and checkfor proper movement.

Note:

5) Slide the vertical stabilizer back inplace. Using a triangle, check to ensure thatthe vertical stabilizer is aligned 90º to the hori-zontal stabilizer as shown in the illustrationbelow.

When cutting through the covering to re-move it, cut with only enough pressure

to cut through the covering itself. Cutting intothe balsa structure may weaken it.

6)Deflect the vertical stabilizer andcompletely saturate each hinge with thin C/Aglue. The vertical stabilizer front surfaceshould lightly contact the fuselage during thisprocedure. Ideally, when the hinges are gluedin place, a 1/64” gap or less will be maintainedthroughout the lengh of the vertical stabilizerto the fuselage panel hinge line.

Note: The hinge is constructed of a specialmaterial that allows the C/A to wick or penetrateand distribute throughout the hinge, securelybonding it to the wood structure of the fuselagepanel and vertical stabilizer.

4) Remove the stabilizer. Using a mod-eling knife, remove the covering from belowthe lines you drew. Also remove the coveringfrom the bottom edge of the stabilizer and thebottom and top edges of the filler block. Leavethe covering in place on the sides of the fillerblock.

INSTALLING THE RECEIVER. 1) Wrap the receiver in the protective foam

rubber to protect them from vibration

2) Using a 2mm drill bit, drill a hole throughthe side of the fuselage, near the receiver, forthe antenna to exit. Route the antenna out ofthe fuselage and secure it to the vertical stabi-lizer using a rubber band and a modified servoarm. See picture as follow.

ATTACHMENT WING-FUSELAGE.

1) Set the tail wheel assembly in place onthe plywood plate. The pivot point of the tailwheel wire should be even with the rudderhinge line and the tail wheel bracket shouldbe centered on the plywood plate.

2) Using a pen, mark the locations of thetwo mounting screws. Remove the tail wheelbracket and drill 1mm pilot holes at the loca-tions marked.

MOUNTING THE TAIL WHEEL BRACKET.

3) Secure the tail wheel bracket in placeusing two 3mm x 15mm wood screws. Becareful not to overtighten the screws.

3. While holding the clasp firmly in place,use a pen and outline the clasp onto the rud-der.

4. Remove the clasp, and using a model-ing knife, remove the covering from inside thelines you drew. Use 220 grit sandpaper andcarefully roughen the inside surface of the ny-lon clasp.

5. Slide the clasp back into position andcarefully glue it into place using Kwik Bond ThinC/A. Hold the clasp in place until the glue com-pletely cures.

1. Using a ruler and a pen place a markonto the bottom of the rudder. The back edgeof the clasp should line up with this mark.You may find it necessary to bend the tail wheelwire down slightly so it lines up with the claspwithout binding.

2. Align the tail wheel wire so that the wireis parallel with the bottom of the rudder. Thecontrol clasp has a predrilled hole through thetop of it. Slide this hole onto the tail wheel wirewhile sliding the clasp over the bottom of therudder.

2) If the nose of the plane falls, the planeis nose heavy. To correct this first move thebattery pack further back in the fuselage. Ifthis is not possible or does not correct it, sticksmall amounts of lead weight on the fuselagesides under the horizontal stabilizer. If the tailof the plane falls, the plane is tail heavy. Tocorrect this, move the battery and receiverforward orif this is not possible, stick weightonto the firewall or use a brass heavy hubspinner hub, similar to those offered by HarryHigley. When balanced correctly, the airplaneshould sit level or slightly nose down whenyou lift it up with your fingers.

BALANCING.

1) It is critical that your airplane be bal-anced correctly. Improper balance will causeyour plane to lose control and crash. The cen-ter of gravity is located 37MM ( 1.5’’) back fromthe leading edge of the wing, measured at thewing tip.

FLIGHT PREPARATION.

4) By moving the position of the adjust-able control horn out from the control surface,you will decrease the amount of throw of thatcontrol surface. Moving the adjustable con-trol horn toward the control surface will in-crease the amount of throw.

CONTROL THROWS.1) We highly recommend setting up the

LASER 200 using the control throws listed atright. We have listed control throws for bothLow Rate (initial test flying/sport flying) andHigh Rate (aerobatic flying).

2) Turn on the radio system, and with thetrim tabs on the transmitter in neutral, centerthe control surfaces by making adjustmentsto the clevises or adjustable servo connec-tors. The servo arms should be centered also.

3) When the elevator, rudder and aileroncontrol surfaces are centered, use a ruler andcheck the amount of the control throw in eachsurface. The control throws should bemeasured at the widest point of each sur-face!

INITIAL FLYING/SPORT FLYING

Ailerons high rate -3/8” up -3/8” downAilerons low rate -3/16” up - 3/16” down

Elevator high rate - 7/8” up -7/8” downElevator low rate -3/8’ up - 3/8” down

Rudder high rate -1 1/4” left and rightRudder low rate - 3/4” left and right

Do not use the aerobatic settings forinitial test flying or sport flying.

B) Check the elevator first. Pull backon the elevator stick. The elevator halvesshould move up. If it they do not, flip the servoreversing switch on your transmitter to changethe direction.

D) Check the throttle. Moving thethrottle stick forward should open the carbu-retor barrel. If it does not, flip the servo re-versing switch on your transmitter to changethe direction.

E) From behind the airplane, look atthe aileron on the right wing half. Move theaileron stick to the right. The right aileronshould move up and the other aileron shouldmove down. If it does not, flip the servo re-versing switch on your transmitter to changethe direction.

C) Check the rudder. Looking frombehind the airplane, move the rudder stick tothe right. The rudder should move to the right.If it does not, flip the servo reversing switch onyour transmitter to change the direction.

PREFLIGHT CHECK.

1) Completely charge your transmitterand receiver batteries before your first day offlying.

2) Check every bolt and every glue jointin the LASER 200 to ensure that everything istight and well bonded.

3) Double check the balance of the air-plane. Do this with the fuel tank empty.

4) Check the control surfaces. All shouldmove in the correct direction and not bind inany way.

8) Properly balance the propeller. An outof balance propeller will cause excessive vi-bration which could lead to engine and/or air-frame failure.

5) If your radio transmitter is equippedwith dual rate switches double check that theyare on the low rate setting for your first fewflights.

6) Check to ensure the control surfacesare moving the proper amount for both lowand high rate settings.

7) Check the receiver antenna. It shouldbe fully extended and not coiled up inside thefuselage.

We wish you many safe and enjoyableflights with your LASER 200.

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

A) Plug in your radio system per themanufacturer's instructions and turn every-thing on.
