PREFLIGHT
CHARGE THE BATTERIES
Follow the battery charging instructions that came with your
radio control system to charge the batteries. You should always
charge your transmitter and receiver batteries the night before
you go flying and at other times as recommended by the radio
manufacturer.
NOTE:
Checking the condition of your receiver battery pack is
highly recommended. All battery packs, whether it's a trusty
pack you've just taken out of another model, or a new battery
pack you just purchased, should be cycled, noting the
discharge capacity. Oftentimes, a weak battery pack can be
identified (and a valuable model saved!) by comparing its
actual capacity to its rated capacity. Refer to the instructions
and recommendations that come with your cycler. If you don't
own a battery cycler, perhaps you can have a friend cycle your
pack and note the capacity for you.
BALANCE PROPELLERS
Carefully balance your propeller and spare propellers before
you fly. An unbalanced prop can be the single most significant
cause of vibration that can damage your model. Not only
will engine mounting screws and bolts loosen, possibly with
disastrous effect, but vibration may also damage your radio
receiver and battery. Vibration can also cause your fuel to foam,
which will, in turn, cause your engine to run hot or quit We use
a Top Flite® Precision Magnetic Prop Balancer™ (TOPQ5700) in
the workshop and keep a Great Planes Fingertip Prop Balancer
(GPMQ5000) in our flight box.
GROUND CHECK
If the engine is new, follow the engine manufacturer's
instructions to break-in the engine. After break-in, confirm
that the engine idles reliably, transitions smoothly and rapidly
to full power and maintains full powerindefinitely. After you
run the engine on the model, inspect the model losely to
make sure all screws remained tight, the hinges are secure,
the prop is secure and all pushrods and connectors are secure.
SET THE CONTROL THROWS
Use a ruler to accurately measure and set the control throw
of each control surface as indicated in the chart that follows.
If your radio does not have dual rates, we recommend setting
the throws at the low rate settings.
NOTE:
The throws are measured at the widest part of the
elevators, rudder and ailerons.
We recommend the following control surface throws:
