and hardener that your particular brand requires.
For example, some epoxies use equal amounts and
some use a 1 to 2 mixture . Mix these together. Coat
one piece with epoxy; squeegee the excess glue off
with scrap wood. The epoxy glue will work better if
there isn't too much oozing out at the edges of the
glued piece. Wipe off any of this excess glue.
In any case, glue is never a substitute for a
good-fitting joint; once the joint is formed, use a
minimum amount of glue and wipe off the excess.
Clamp, pin or hold the joint while the glue is drying.
Remember: Take your time and follow di-
rections to end up with a well-built model that
is straight and true.
BUILDING HINTS
Your work area ideally should be large and com-
fortable enough for you to work without having to
put everything away every night. (The kitchen table
is not recommended!) The key to a straight fuselage
and warp-free wings is a straight, flat building board
or work bench. Remember, your model is only as
straight as the board you build on. Have all your
tools handy and your building will go much easier.
Build over the plans when instructed. Cover
the part of the plan you are using with waxed paper
so you don't glue the model to the plans! If the parts
do not match the plans exactly, it is because the plans
have changed size with moisture in the air. Do not
be concerned about this. The parts were all cut to fit
each other. Use the plans as a guide.
Remember this: In order for your PT40 to per-
form as it should it is your responsibility to take your
time when building and to follow all the instructions
given. A careful builder will produce a model that is
straight, true and warp-free. A well built model per-
forms best and will fly like it was designed to. So
take your time and enjoy!
If at all possible, get an experienced model buil-
der to look at your model during the construction
process. It is much easier to make corrections at these
times.
The building instructions follow. If you have
any questions about building or flying the PT40,
please call us at (217) 398-8970 and we'll be glad to
help.
It is a good idea to obtain the following items
before you start building as you will need to install
or test fit some of them before assembly is complete.
Most of these items can be purchased from your local
hobby dealer.

Note: As with any other hobby, you may go "all
out" if you choose by purchasing all sorts of special
hobby tools and accessories (there are hundreds avail-
able). However, most of the PT40 parts are accurately
pre-cut so you can build it without a lot of special
tools. Some of the more advanced R/C kits require
the builder to do a lot more cutting and sanding, so
you may eventually want to equip your workshop
with tools like a Dremel Moto Tool, jig saw, small
table saw, disk/belt sander, small drill press, small
band saw, etc., but these are not necessary now.
SPECIAL NOTE ON ENGINES
Choose the right sized engine for the PT40 as
indicated here. We recommend a .25 to .40 two cycle
engine or a .30 to .45 four cycle engine. Too large or
too small an engine can result in an unsafe or poor
flying model. Remember that a model engine is not
a "toy" but a device that can cause serious bodily
harm to you or others on the ground or cause harm
in the air if abused or misused.
