NOTE: This applies to both the V-tail and
straight tail.

TRIM MIXING:

If your transmitter has flap to

Elevator mixing, we recommend mixing 1/32" of

down

elevator at half flaps and 1/16" of down

elevator at full flaps. This will keep the nose level
when the flaps are deployed.

The surface throws and balance point listed

in this manual are the ones at which the
Bonanza flies best. Set up your aircraft to

those specifications. If, after a few flights,
you would like to adjust the throws to suit
your tastes, that is fine. The Bonanza has

large elevators and does not require much
throw. Too much throw can force it into a
stall,

so remember

...

More is not better.

PREFLIGHT

CHARGE YOUR BATTERIES

Follow the battery charging procedures in your

radio instruction manual. 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.

BALANCE YOUR PROPELLERS

Carefully balance your propellers 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 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.

FIND A SAFE PLACE TO FLY

The best place to fly your model

an AMA

chartered R/C club flying field. Contact the AMA

(their address is on page 3) or your hobby shop

dealer for the club in your area and join it. Club
fields are intended for R/C flying, making your
outing safer and more enjoyable. The AMA also

provides insurance in case of a flying accident.

an RIC flying field is not available, find a large,

grassy area at least six miles from buildings,
streets, and other RIC activities. A schoolyard is

usually not an acceptable area because of people,
power lines and possible radio interference.

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 connectors are
secure.

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
defective cell in your battery pack, or a damaged
receiver crystal from a previous crash.

ENGINE SAFETY PRECAUTIONS

NOTE:

Failure to follow these safety

precautions may result in severe injury to
yourself and others.

Store model fuel in a safe place away from high

heat, sparks or flames.

not smoke near the

engine or fuel as it is very flammable. Engine
