Earlier we touched on engine recommendations. Your
Elder Biplane kit contains a high-quality filled nylon motor
mount that will work with some of the engine suggestions
or this design, but not all. If the engine choice for your
Elder Biplane will not work with this mount, it might be
necessary to visit your local retail hobby shop to obtain
the correct motor mount for your engine.
IMPORTANT NOTE:
TOP FLITE MODELS, INC. Would certainly recommend
the Elder Biplane as a first R/C powered aircraft.
However, if you are a beginner to the sport of R/C flying,
we would urge you to seek and use experienced
assistance in constructing and flying this airplane.
Again, if you are new to this hobby, consider this:
Flying this or any other radio-controlled model aircraft is
a PRIVILEGE and not a RIGHT and this privilege begins
with the utmost safety considerations to others and
yourself as well. An R/C model airplane in inexperienced
hands has the potential of doing serious personal or pro-
perty damage. These safety considerations start at the
building board by following instructions, seeking com-
petent help when you are confused and avoiding short-
cuts. These considerations have to be carried overto the
flying field where safety must come first and limitations
cannot be exceeded. We urge you to:
1.Send for and obtain your AMA (Academy of Model
Aeronautics) membership which will provide in-
surance for your R/C activities — DO NOT RELY ON
HOMEOWNERS INSURANCE.
2. Join an AMA sanctioned R/C flying club in your area
where you can obtain competent, professional in-
struction in trimming and learning how to fly this
model.
Check with your favorite local hobby shop for the re-
quired AMA forms or the address where they can be ob-
tained.
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 control device. It is important to follow all
directions as to the construction of this kit as well
as installation and use of the engine and radio
gear. The advice and assistance of a well ex-
perienced builder and pilot is highly recommend-
ed. Don't take chances! Improper building, opera-
tion, or flying of this model could result in serious
bodily injury to others, yourself, or property
damage.
PRE-CONSTRUCTION NOTES
The Elder Biplane, like other Top Flite kits employs the
use of die-cut wood to ease the task of construction,
parts fit and identification. The dies used for this kit
have been rigorously checked for absolute accuracy
and should provide you with excellent fit. Die-cut parts
should be carefully removed from their sheets by first
lightly sanding the back of each sheet of parts and then
carefully removing each part. Use a light garnet paper
for the sanding and keep a sharp hobby knife with an
X-acto #11 blade, or equivalent, handy for assistance in
removing any parts that might not have completely cut-
through by the dies. Parts which oppose one another
and must be precisely uniform—such as fuselage sides,
ribs, etc.—should be carefully "matched" after their
removal from the part sheets. Matching is the process of
holding the opposing pieces together with either pins,
tape or spot gluing and lightly sanding the edges of the
parts until they are identical. A sanding block with light
garnet paper is most useful for this and other phases of
construction.
Your building surface should be at least large enough to
accommodate the wing panels. This surface should be
as absolutely flat as possible and yet be able to accept
pins easily. We have found that a product such as
Celotex fiber board works quite well for this purpose.
Anothergood surface can be found in most well-stocked
hardware s t o r e s - a 2 ' x 4 ' f i b e r b o a r d ceiling tile. These
are quite inexpensive and can be used for several
airplanes before needing replacement.
As with most R/C kits that are constructed from wood, a
selection of tools - most of which can be found in the
average workshop - are a must to do the job correctly:
• Hobby knife and sharp #11 blades
• Single-edge razor blades
•T-pins
• Sanding blocks in assorted sizes
• Sandpaper in various grits
• Hand-held hobby saw, such as an X-acto
• Dremel tool or power drill and assorted drill bits
• Straight-edge, preferably metal, at least 36" long
• 90" triangle
• Soldering iron, flux (silver) and solder
• Carbide cut-off wheel for wire cutting
• Small power jig-saw, such as a Moto-Saw
• Razor plane
• Tapes, such as masking and cellophane
Our Elders were constructed using a variety of
common hobby adhesives including 5-minute epoxy,
cyano-acrylates, and 1-hour epoxy. Since all of us have
our own construction techniques and favorite
adhesives, stick with the ones you are familiar with and
prefer. However, in certain areas there will be callouts for
certain types of adhesives, and we urge you to try not to
substitute since doing so could possibly cause
problems structurally.
The last thing we should touch on before we begin
actual construction is the sequence in which the Elder is
assembled. The sequence given to you in this booklet
has proven to be the most straight-forward and provides
the finished components in the order in which you will
need them to progress to the next assembly phase. Try
to stick with the building order presented here to avoid
mistakes.
