The balance point and control surface
throws listed in this manual are the ones at
which the Explorer flies best. Set up your
aircraft to those specifications. If, after a
few flights you would like to adjust the
throws or C.G. to suit your tastes that is
fine.
Too much control surface throw can make
your model difficult to control or force it
into a stall, so remember... more is not
better.
PREFLIGHT
Identify your model
Regardless if you fly at an AMA sanctioned
R/C club site or if you fly somewhere on
your own, you should always have your
name, address, telephone number and
AMA number on or inside your model. It is
required at all AMA R/C club flying sites
and AMA sanctioned flying events.
Charge the batteries
Follow the battery charging procedures in
the radio instruction manual. Always
charge your transmitter and receiver
batteries the night before you go flying
and at other times as recommended by the
radio manufacturer.
Balance the propeller
Carefully balance your propeller before you
fly. An unbalanced prop is 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 the
fuel
to foam, which will cause the engine to run
hot or
quit.
Ground check your model
If you are not thoroughly familiar with the
operation of R/C models, ask an
experienced modeler to inspect your radio
installation and control surface set-up.
Follow the engine manufacturer's
instructions to break-in your engine. After
you run the engine on your model, inspect
your model closely to make sure all screws
remain tight and your pushrods and
Range check your radio
Ground check the range of your radio
before the first flight of the day. With the
transmitter antenna collapsed and the
receiver and transmitter on, you should be
able to walk at least 100 feet away from
the model and still have control. Have an
assistant stand by your model and, while
you work the controls, tell you what the
control surfaces are doing. Repeat this test
with the engine running at various speeds
with an assistant holding the model, using
hand signals to show you what is
happening. If the control surfaces do not
respond correctly, do not fly! Find and
correct the problem first. Look for loose
servo connections or broken wires,
corroded wires on old servo connectors,
poor solder joints in your battery pack or a
