USING THIS INSTRUCTION MANUAL
Before you begin assembling your Laser 200 ARF, take
some time to read through this entire instruction book. It is
designed to take you step-by-step through the process and
to give you added information on motor and radio selection
and set-up, balancing your aircraft, and flying your model.
The time you spend will speed the assembly process and
help you avoid problems.
PREPARING FOR ASSEMBLY
You will need a work area of approximately 24 x 48" which has
been covered to protect it from adhesive, as well as cuts and
other damage. Many people cover their work area with a
sheet of dry wall (sheet rock) and/or waxed paper t o pre-
vent CAGlue and Epoxy from ruining the work surface.
CONSTRUCTION TIPS
IMPORTANT: ALWAYS READ A FEW STEPS AHEAD.
This will alert you to coming instructions and will help you
plan accordingly.
Using the Parts Identification section, familiarize yourself
with the various items included in your kit box.
Do not hesitate to ask questions. Your local hobby dealer
and area flyers will most likely be happy to help, as they
want you to have a successful flying experience.
ADHESIVES & GLUING TECHNIQUES
CA adhesives are specially formulated to firmly glue the
plywood, hardwood, and balsa used in your model and to
withstand the vibration and stresses of high performance
flight. However, there are times, such as when you are
installing the stabilizer and fin on the fuselage and want
more set-up time for careful alignment and positioning,
then you should use epoxy. Occasionally, you also will
want to use thin CA, which "wicks" into the surrounding
areas. Aliphatic resin glue or similar water-based glues can
also be used, but they will add to the assembly time
because they dry so much more slowly than CA glue.
Remember, when ever using any CA, you must be careful
to read instructions thoroughly, as you will have only sec-
onds for positioning of parts. Be sure to trial fit parts
together before gluing. Also, never use watery THIN type
CA glue for gluing plywood and hardwood parts. Thin CA's
do not adequately bond these areas.
CAUTION
Some people may experience an allergic reaction when
exposed to fumes from CA glue or epoxy. As with paints,
thinners, and solvents, it is always important to use glues
only where there is adequate ventilation to carry fumes
away. A fan is recommended. Also, special care must be
taken when using CA, as it will bond skin as well as other
surfaces. Before using any CA, carefully read all label pre-
cautions. When using CA, protective eye-wear and care in
keeping the glue away from the face is highly recommend-
ed. If CA does happen to get into the eye, hold lid open
and flush with water only. Seek immediate medical atten-
tion.
COVERING
The Laser 200 ARF is covered in a polyester film chosen
for its beauty, toughness, and ease of application and
repair. It is not uncommon for ARF's to develop a few wrin-
kles in transit. If this is true of your model, the situation is
easily corrected. Before you begin putting the pieces
together, run around the edge of the seams first then over
the surface of each section with an iron (either specially
designed for airplane use or the more cumbersome house-
hold iron). Apply the heat (set at about 300° F), following
along with a soft cloth and pressing down on the covering
as you go around. This will more firmly set the covering
adhesive into the wood and keep your aircraft covering
tight and smooth in the future. Once you have ironed the
seams stay away from them with the heat or the covering
will slide when you try to shrink the middle. If this happens
the wrinkles will not come out of the covering.
One of the great advantages of polyester film is that it can
be applied over itself without causing gas bubbles. This
allows you to repair your aircraft, as well as to customize it
in a number of ways. If, due to a flight mishap, you get a
hole or similar covering damage, simply trim away the
ragged edges and then apply a patch, following the direc-
tions that come with your covering , which is available at
your hobby dealer.
The Laser 200 covering can be closely matched
using
Oracover Deep Red #871
Oracover White #870
Oracover Gold #879
Important Information:
This is a 3D airplane and you
must use throttle control to
avoid over speeding the
plane and inducing flutter in
the large control surfaces.

which reach greater than 140° Fahrenheit
(60C) will usually become damaged and
could catch fire.
Do not charge or discharge Li-Po cells on or near
combustible materials including paper, plastic,
carpets, vinyl, leather, wood, inside an R/C
model or full size automobile.
Do not expose Li-Po cells to water or moisture at any
time.
Do not store batteries near an open flame or heater.
Do not assemble Li-Po cells or pre-assembled packs
together with other Li-Po cells or packs.
Do not allow a Li-Po battery to be left unattended dur-
ing charging or discharging.
Always store Li-Po batteries in a secure location
away from children.
Always remove a Li-Po battery if model is involved in
any kind of crash. Carefully inspect the
battery and connectors for even the
smallest damage.
CAUTION, cells may be hot!
Do not allow the electrolyte to get into eyes or on
skin. Wash affected areas immediately if
they come into contact with electrolyte.

You will want to adjust these throws to suit your flying abilities. The throws given are starting
throws.
Balancing
Balance the Laser 200 at 2-5/8 back from the leading edge of the wing next to
the fuselage.

11
Glow Engine Conversion
You may wish to convert the Laser to a glow engine. We recommend no larger than a .015 which will
give very good performance. You will need to install a thicker firewall, up-grade the servos from micro to mini,
and reinforce the motor box. None of the material need for the conversion is included in the kit.
1. You will need a motor mount and mounting
bolts for the your motor.
2. Mount you motor to the mounts and meas-
ure from the surface of the table to the front
of the thrust washer (surface the prop will
mount on).
3. Measure from firewall to the front of the
cowl.This should be approximately 2-1/4”.
Using your measurement from the motor,
adjust the length of the motor box. Our
motor measured 3” from table to prop hub
so we cut 5/8” off the motor box length (1/8”
clearance from front of cowl).
Cut the motor box off to the proper length
cutting a 2 degree angle for right
thrust.(approximately 1/16” shorter on the
right side).
4. Epoxy the 1/4” firewall in place between the
original motor box sides and bottom.
The cross braces on the top of the motor
box can be removed.
5. Sheet the bottom and both sides of the
motor box with 1/16” plywood.

12
6. Mark the firewall center with vertical and
horizontal lines. Offset the vertical line 1/8”
to the left to compensate for the right thrust.
8. The fuel tank can now be fitted in the nose
of the plane. Use foam rubber to hold in
position. Some material on the F1 former
will need to be removed on the bottom side
of the bulkhead.
9. Cut two blocks of wood 1/4” thick by 3/4” x
1” and mount the throttle servo to them.
Install an e-z connector on the output arm.
11. Bolt the muffler in place and cut a scrap
piece of paper to fit around it.
Tape the paper to the bottom of the fuse-
lage.
remove material
7. Drill a 3/16” hole in the firewall in line with
your throttle output arm and flush with the
bottom floor.
Install a 2-56 pushrod with clevis to the
motor.
10. Glue the throttle servo in place and attach
the throttle pushrod to the e-z connector.

13
13. The switch can be mounted in the fuselage
on a plate or can be mounted in the turtle
deck.
If necessary to achieve the proper balance
the battery can be mounted on a shelf in the
turtle deck.
12. Fit the cowl in place and transfer the muffler
location to the cowl.
Make the cutout starting small and increas-
ing till large enough.
Use the same method to locate the needle
valve and glow plug access hole.
This completes the glow fuel conversions.
Balance the model in the same place as the
electric. We used the same spinner as the
electric version (Carl Goldberg 1-3/4”)
Props from 8-3 to 9-5 will work on the .15,
just make sure you motor will turn the prop
you choose at the proper RPM.
14. Up grade the servos from micro to mini. It
may be necessary to reinforce the mounts.
Important Information:
This is a 3D airplane and you must use throttle control to
avoid over speeding the plane and inducing flutter in the large
control surfaces.
