Great Planes Yak-55 EP 3D ARF - GPMA1190 - Manual (Page 3)

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 motor and components
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 a motor 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.
Remember: Take your time and follow the instructions to
end up with a well-built model that is straight and true.
WARNING!! Read the entire instruction sheet included with
this battery. Failure to follow all instructions could cause
permanent damage to the battery and its surroundings, and
cause bodily harm!
