CONGRATULATIONS'
You now own the most accurate
produced
We
at Top Flite hope that you will find this model the most
pleasant to build, inspiring to look at and exciting to fly that you
have ever constructed
It
is honest to point out, however, that while this model is
more difficult - in fact is simpler than most comparable kits to
make,
R/C
scale models generally are not for the newcomer to
this hobby Previous modeling experience and careful attention to
craftsmanship are necessary Even the "old hand" will do well to
study and follow the instructions and guidance given in this booklet.
It is-our aim to have you say "This is the finest model I have ever
built".
CONSTRUCTION OF THE A6M2 ZERO
BEFORE YOU START, READ THIS
The assembly sequence of your Top Rite
fully developed to help assure the correct alignment of your model
Utilize the check-off blocks as you build this will allow assembly
of your model in minimum time
Before beginning an assembly step, read the instructions to fami-
liarize yourself with the parts to be used Find the parts mentioned and double check them for proper identification and size with
the plans Do not separate parts from the die cut sheets until you
need them There are machined parts in the kit which are not
identified such as the leading edges, wing tips, etc These parts
can be easily identified by checking the parts against the plan.
We are sometimes asked which glues are best for model construction The answer to this depends upon the particular job This is
our normal recommendation For all hardwood to hardwood or
hardwood-to balsa joints, use white
especially good, as it dries faster than other white glues and is very
strong For balsa-to-balsa joints, regular balsa-wood cements are
ample for the job, although white glue can be used here too.
Whichever type you use, remember that excess glue is no substitute for a well fitting joint Use a minimum of glue at all times,
and wipe off excess glue that squeezes out of joints before it sets
hard, when set it is difficult to remove, but if not removed it
could spoil the covering job.

USE COMMON SENSE
When you have completed this model, you will have invested
considerable time, money and skill Protect this investment by,
1. Re-checking all critical building points (center of gravity,
hingeing of control surfaces, strength of stress areas, etc ).
2. Correctly installing the radio gear
3. Test and re-test the radio, all moving surfaces, landing gear
(if retracts), condition of batteries, etc.,

WARNING!!
A radio controlled model is not a "TOY" Care and caution
must be taken in properly building the model as well as in
the installation and use of the radio controlled device It is
important to follow all directions as to construction of this
kit as well as installation and use of the engine, propellers
and radio gear The advice and assistance of a well experienced builder and pilot is highly recommended Don't
take chances Improper building, operation or flying of
model could result in serious bodily injury to others, your-
self, or property damage

Follow each step in order and put check marks in
the blocks as you complete each phase described.
IMPORTANT NOTE TO BUILDER
Every model built from a kit is different, reflecting the level of
skill as well as the favored building techniques of the modeler
ultimately thus, each model is essentially the individual creation
of
that builder.
Changes and variations take place in building so that while Top
Flite supplies most essential building materials, the end product
is the creation of the builder
Therefore, Top Flite assumes no responsibility for the performance of the model, nor does Top Flite assume any responsiblity
of any nature whatsoever for the loss of, or property damage
resulting from the operation of this model when it is completed

to the larger plan at the dotted lines Before you do
any building of this kit, we suggest you spend a few
hours reading and studying this book and the plans.

be made before the wing construction is started
Again the decision to use landing gear retracts must be made before
construction begins Construction provisions have been built into
the model for retracts There is room in the center of the wing,
