Decisions You Must Make; Radio Equipment; Power System Recommendations - GREAT PLANES Christen Eagle .46 Instruction Manual

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 ensure 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, wheel pants, and landing gear
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 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.
We, as the kit manufacturer, provide you with a top quality,
thoroughly tested kit and instructions, but ultimately the
quality and fl yability of your fi nished 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 the instructions
to end up with a well-built model that is straight and true.

DECISIONS YOU MUST MAKE

This is a partial list of items required to finish the Christen
Eagle .46 ARF that may require planning or decision making
before starting to build. Order numbers are provided in
parentheses.

Radio Equipment

The Eagle requires a minimum 4-channel radio system with
two 44 oz.-in. [3.2 kg-cm] minimum standard sized servos.
Two micro servos are required for the ailerons in the bottom
wing. Two more micro servos are required if you plan to
have the top wing ailerons controlled by their own dedicated
servos. If you are installing a glow engine, an additional
standard servo is required for the throttle.
Two 12" [305mm] servo extensions are required for the bottom
wing aileron servos. If you plan to install aileron servos in the
top wing, you will need four more 12" [305mm] servo extensions
for a total of six. If you are using a radio system that does not
support mixing functions, a Y-harness (dual servo extension)
will also be required to connect the bottom aileron servos to
the receiver. If you have installed servos in the top wing, two
additional Y-harnesses will also be needed for a total of three. A
6" [152mm] servo extension is needed for the receiver pack if
you plan to install a brushless motor.
