Great Planes Yak-54 1.60 ARF - GPMA1411 - Manual (Page 3)

The Great Planes Yak 54 1.60 ARF is an excellent sport-
scale model and is eligible to fly in IMAA events. The IMAA
(International Miniature Aircraft Association) is an
organization that promotes non-competitive flying of giant-
scale models. If you plan to attend an IMAA event, obtain a
copy of the IMAA Safety Code by contacting the IMAA at
the address or telephone number below.

1. Your Yak 54 1.60 ARF should not be considered a toy, but
rather a sophisticated, working model that functions very
much like a full-size airplane. Because of its performance
capabilities, the Yak 54 1.60 ARF, if not assembled and
operated correctly, could possibly cause injury to yourself or
spectators and damage to property.
2. You must assemble the model according to the
instructions. Do not alter or modify the model, as doing so
may result in an unsafe or unflyable model. In a few cases
the instructions may differ slightly from the photos. In those
instances the written instructions should be considered
as correct.
3. You must take time to build straight, true and strong.
4. You must use an R/C radio system that is in first-class
condition, and a correctly sized engine and components
(fuel tank, wheels, etc.) throughout the building process.
5. You must correctly install all R/C and other components so
that the model operates correctly on the ground and in the air.
6. You must check the operation of the model before every
flight to insure that all equipment is operating and that the
model has remained structurally sound. Be sure to check
clevises or other connectors often and replace them if they
show any signs of wear or fatigue.
7. If you are not an experienced pilot or have not flown this
type of model before, we recommend that you get the
assistance of an experienced pilot in your R/C club for your
first flights. If you're not a member of a club, your local hobby
shop has information about clubs in your area whose
membership includes experienced pilots.
8. While this kit has been flight tested to exceed normal use,
if the plane will be used for extremely high-stress flying,
such as racing, or if an engine larger than one in the
recommended range is used, the modeler is responsible for
taking steps to reinforce the high-stress points and/or
substituting hardware more suitable for the increased stress.
9. WARNING: The cowl and wheel spats included in this kit
are made of fiberglass, the fibers of which may cause eye,
skin and respiratory tract irritation. Never blow into a part
(cowl) to remove fiberglass dust, as the dust will blow back
into your eyes. Always wear safety goggles, a particle mask
and rubber gloves when grinding, drilling and sanding
fiberglass parts. Vacuum the parts and the work area
thoroughly after working with fiberglass parts.
Remember: Take your time and follow the instructions to
end up with a well-built model that is straight and true.
This is a partial list of items required to finish the Yak 54 1.60
ARF that may require planning or decision-making before
starting to build. Order numbers are provided in parentheses.
The fuel tank included with this kit is suitable for use with
glow fuel. However, if using a gas engine, the fuel tank must
be converted to work with gasoline. This can be done by
purchasing a Sullivan #484 Gasoline/Diesel fuel tank
conversion kit (SULQ2684), a package of Du-Bro #813 1/8"
[3.2 mm] I.D. fuel line barbs (DUBQ0670) and 3' of Great
Planes gasoline fuel tubing (GPMQ4135). Without the fuel
line barbs, some types of gas-compatible fuel line may slip
off the metal fuel tubes. If the Sullivan conversion kit is not
available, the Du-Bro #400 gas conversion stopper
(DUBQ0675) and one 12" [300 mm] piece of K+S 1/8" [3.2
mm] soft brass tubing (K+SR5128–box of 5) could also be
used to make the conversion.

DECISIONS YOU MUST MAKE
We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and flyability 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.
