Top Flite TOPA0950 - Manual (Page 3)

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 fl ight 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
fl own this type of model before, we recommend that
you get the assistance of an experienced pilot in your
R/C club for your fi rst fl ights. 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 fl ight tested to exceed
normal use, if the plane will be used for extremely
high stress fl ying, 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.
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 fi nish the P-51
Mustang ARF that may require planning or decision
making before starting to build. Order numbers are
provided in parentheses.
BUILDING STAND
A building stand or cradle comes in very handy
during the build. We use the Robart Super Stand II
(ROBP1402) for most of our projects in R&D, and it
can be seen in pictures throughout this manual.
RADIO EQUIPMENT
A 6-channel radio system such as a Futaba ® 6EXAS
with a standard receiver and six standard size servos
with a minimum torque of 44 oz-in [3.2 kg-cm] are
required for the control surfaces of the P-51 Mustang
ARF. The included mechanical retracts require a
180° retract servo. If you will be installing optional
pneumatic retracts, a micro servo will be required
to operate the air valve. One standard torque servo
such as an S3003 is required for the throttle. Two 24"
[610mm] servo extensions (aileron servos) and two Y-
harnesses (aileron and fl ap servos) are also required.
A receiver battery pack with a minimum capacity
of 1000mAh is recommended. Order numbers are
provided as follows:

SCALE COMPETITION
Though the Top Flite P-51 Mustang ARF may not have
the same level of detail as an “all-out” scratch-built
competition model, it is a scale model nonetheless
and is therefore eligible to compete in the Fun Scale
class in AMA competition (we receive many favorable
reports of Top Flite models in scale competition!). To
receive the fi ve points for scale documentation, the only
proof required that a full-size aircraft of this type in your
paint/markings scheme did exist is a single sheet such
as a kit box cover from a plastic model, a photo, or a
profi le painting, etc. If the photo is in black and white
