servo reversing in the transmitter to make the controls
respond correctly.

Use a Great Planes AccuThrow (or 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

between

the high and low rate settings.

Note: The throws are measured at the widest part of the
elevators and rudder.

No matter 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. Fill out the identification
tag on page 23 and place it on or inside your model.

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 taken out of another model, or a new battery
pack, 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. We recommend the Hobbico Accu-Cycle

Plus (HCAP0270).

Carefully balance your propeller and spare propellers before
flying. An unbalanced prop can be the single most
significant cause of vibration that can damage the model.
Not only will engine mounting screws and bolts loosen,
possibly with disastrous effect, but vibration may also
damage the radio receiver and battery. Vibration can also
cause fuel to foam, which will, in turn, cause the 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.

If the engine is new, follow the engine manufacturer’s
instructions to break-in the engine.
After break-in, confirm

PREFLIGHT

IMPORTANT: The Super Sportster 40 MK II ARF has
been extensively flown and tested to arrive at the throws
at which it flies best. Flying your model at these throws
will provide the greatest chance for successful first flights.
If, after you have become accustomed to the way the
Super Sportster 40 MK II ARF flies, you would like to
change the throws to suit your taste, that is fine. However,
too much control throw could make the model difficult to
control, so remember, “more is not always better.”

These are the recommend control surface throws:
