Great Planes Ultra Sport 40 Kit - GPMA0410 - Manual (Page 3)

INTRODUCTION
Congratulations! Thank you for purchasing the
Great Planes Ultra Sport 40! Jim Feldmann's original
design Ultra Sport 60 was featured as a construction
article in the August, 1989 issue of RC Modeler maga-
zine, and has been hailed by many as "the best sport
flying airplane ever''! The design starts with the legen-
dary "Kaos" wing planform, and features modem styl-
ing and state-of-the-art construction techniques. The
result is an ultra-stable, ultra-smooth flying airplane that
does what you want it to, no more and no less.
The Ultra Sport 40 is easy to build, totally predict-
able, smooth-flying and has very docile stall characteris-
tics, making it the ultimate sport airplane for the modeler
who wants to fly with a higher degree of precision. Be-
cause it naturally tracks through maneuvers better than
other sport airplanes, you' 11 fly better when you' re flying
an Ultra Sport 40.
This is not a beginner's airplane! While the
Ultra Sport 40 is easy to build and flies great, we must
discourage you from selecting this kit as your first R/C
airplane. It is fast, highly maneuverable, and lacks the
self-recovery characteristics of a good basic trainer
such as the Great Planes PT Series airplanes. On the
other hand, if you have already learned the basics of R/
C flying and you are able to safely handle an "aileron
trainer" airplane such as the Great Planes Trainer
Series or Big Stick Series airplanes, the Ultra Sport 40
is an excellent choice.
PRECAUTIONS
1. You must build the plane according to the plans
and instructions. Do not alter or modify the model as
represented by the plans, as doing so may result in an
unsafe or unflyable model. In a few cases the plans and
instructions may differ slightly from the photos. In those
instances you should assume the plans and written in-
structions are correct.
2. You must take time to build straight, true and
strong.
3. You must use a proper R/C radio that is in first
class condition, the correct sized engine and correct
components (fuel tank, wheels, etc.) throughout your
building process.
4. You must properly install all R/C and other com-
ponents so that the model operates properly on the
ground and in the air.
5. You must test the operation of the model before
the first and each successive flight to insure that all
equipment is operating, and you must make certain that
the model has remained structurally sound. Be sure to
check the nylon clevises and horns often, and replace if
they show signs of wear.
6. You must fly the model only with the competent
help of a well experienced R/C pilot if you arc not
already an experienced and knowledgeable R/C pilot at
this time.
Note: We, as the kit manufacturer, can provide you
with a top quality kit and great instructions, but
ultimately the quality and fly ability of your finished
model depends on how you build it; therefore, we
cannot in any way guarantee the performance of
your completed model, and no representations are
expressed or implied as to the performance or safety
of your completed model.
Remember: Take your time and follow
directions to end up with a well-built model that
is straight and true.
INSTRUCTIONS IN BOXES LIKE THIS
ARE VERY IMPORTANT AND SHOULD
BE FOLLOWED CAREFULLY.
