Decisions You Must Make; Glow Engine Option & Required Parts; Gasoline Engine Option & Required Parts; Radio System Recommendations - GREAT PLANES Waco YMF-5 Instruction Manual

4. You must use an R/C radio system that is in good condition,
a correctly sized engine, and other components as specified
in this instruction manual. All components must be correctly
installed so that the model operates correctly on the ground
and in the air. You must check the operation of the model and
all components before every flight.
5. 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.
6. While this kit has been flight tested to exceed normal use,
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.
7. WARNING: The cowl, wheel pants, and some fairings are
made of fiberglass, the fibers of which may cause eye, skin
and respiratory tract irritation. Never blow into or on 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.
