Biplane
RC-37 INSTRUCTION MANUAL
INTRODUCTION
The Elder Biplane is the third
design based on the popular
Elder-series of models. This
design is a direct result of popular
demand and it surely is the
largest model of the three. Your
Elder Biplane packs a huge wing
area of 1492 square inches, that's
10.3 square feet of lifting surface!
This means that when the model
is built within the expected
weight range of 7-1/2-8-1/2 pounds,
the resulting wing loading range
would be 11.6 - 13.1 ounces per
square foot! It also means that if
you went with the heaviest engine
available and went crazy in the
detailing and finishing aspects of this model and manag-
ed to get the weight up to 10 pounds, the wing loading
would still only be 15.4 ounces per square foot!
All of the above allows your Elder Biplane to be powered
by a very wide range of engines. This design has been
tested quite successfully using 2-stroke engines as small
as .45 and on up to .75's. For 4-stroke work, we suggest
engine sizes of .60 to .90 in displacement. Like its smaller
counterparts, the real "kick" of this design is its extreme-
ly realistic flight characteristics. Slow fly-bys are breath-
taking without the fear of losing aileron authority. Land-
ings and take-offs are absolutely effortless. In the airyour
Elder Biplane is fully capable of some of the most realistic
aerobatics you've ever seen! You can expect beautiful
loops, stall turns and snap rolls, all at speeds that actual-
ly allow you to watch the airplane instead of a "blur".
Your Elder Biplane is a rugged design that will operate
very nicely out of dirt, grass or paved flying fields. The uni-
que, shock-absorbing landing gear, proto-typical of the
Elders era, really works to smooth out even the bumpiest
of fields. With its thick airfoil section and generous wing
area, your Elder Biplane will not tend to build-up ex-
cessive airspeed. This characteristic keeps the relative
inertia low and means that crash damage is kept to a
minimum.
Like otherEIders, the Elder Biplane lends itself to all kinds
of detailing, if you're so inclined. For the beginner,
nothing fancy is needed; just fly it and enjoy. For the
builder with an imagination, the Elder Biplane can be
detailed to such a degree that other pilots at your field will
swear the airplane is a scale model! In the COVERING &
FINISHING section of these instructions there are some
ideas for detailing that might be of interest, please take
the time to read them.
