exhaust gives off a great deal of deadly carbon

monoxide

so do not run the engine in a closed

room or garage.

Get help from an experienced pilot when you

learn to operate engines.

Use safety glasses when you operate model

engines.

Do not run the engine near loose gravel or sand;

the propeller may throw loose material in your face
or eyes.

When you start and run the engine, keep your

face and body as well as all spectators away from
the plane of rotation of the propeller.

Always be

aware and very conscious of hand

movements and be

deliberate in your reach for the

needle valve, glow plug clip, or other items near a

spinning propeller.

Keep loose clothing, shirt sleeves, ties, scarfs,

long hair or loose objects away from the prop. Be

conscious of pencils, screw drivers or other objects
that may fall out of your shirt or jacket pockets.

Use a

chicken stick or electric starter and follow

the instructions to start your engine.

Make certain the glow plug clip or connector is

secure

so

that it will not pop off or get into the

running propeller.

Ask an assistant to hold the model from the rear

while you start the engine and operate the controls.

Make all engine adjustments from

behind the

rotating propeller.

The engine gets hot!

Do not touch the engine

during or immediately after you operate it. Make
sure fuel lines are in good condition

so fuel will not

leak onto a hot engine and cause a fire.

To stop the engine, close the carburetor barrel

(rotor) or pinch the fuel line to discontinue the fuel

flow.

Do not use your (or any body ekes') hands,

fingers or any body part to stop the engine. Never
throw anything into the prop of a running engine.

FLYING

The Top Flite Beechcraft Bonanza is a great flying
sport scale airplane that flies smoothly and
predictably, yet is highly maneuverable. Compared
to other scale models, its flight characteristics are
docile and forgiving. The Bonanza also has
excellent slow speed flight characteristics. It does

not, however, have the self-recovery characteristics
of a primary

R/C trainer; therefore, you must either

have mastered the basics of R/C flying or obtained

the assistance of a competent R/C pilot to help you

until you are able to safely and competently pilot

the model by yourself.

FUEL MIXTURE ADJUSTMENT

A fully cowled engine may run at a higher
temperature than an un-cowled engine. For this

reason, the fuel mixture should be richened so the

engine runs at about 200 rpm below peak speed.

By running the engine slightly rich, you will help
prevent dead stick landings caused by overheating.

If you have dual rates on your transmitter, set the

switches to "high rate" for takeoff, especially when
taking off in a crosswind. Although this model has
good low speed characteristics, you should always
build up as much speed as your runway will permit
before lifting off. This will give you a safety margin

in case of a "flame-out." Use as much of the
available runway as possible and practical. When

the plane has sufficient flying speed, lift off by
smoothly applying up elevator (don't "jerk" it off into

a steep climb!), and climb out gradually.

Do not use

TAKEOFF

flaps for your initial takeoff. After you have the feel
of the Bonanza, takeoffs may be made with the
flaps set at 50%. Never use 100% flaps for takeoff

,ecause of the high drag.

1.20

4-STROKE NOTE:

If you have installed a 1.20

4-

stroke engine, you must manage the throttle on takeoff
and throughout the flight! Use slightly more than half
throttle for your first few takeoffs and be ready to apply

right rudder to counteract torque as you increase
power. Add power gradually until you become familiar
with the Bonanza's flight characteristics.

FLIGHT

We recommend that you take it easy with your

Bonanza for the first several flights, gradually

getting acquainted with this realistic model as your
engine gets fully broken-in. Add and practice one

maneuver at a time, learning how she behaves in

each. For ultra-smooth flying and normal

maneuvers, we recommend using the low rate

settings as listed on page 68 & 69. High rate
elevator may be required for crisp snap rolls and
spins. With a 1.20 engine the Bonanza really
scoots along,

so you should manage the throttle

when performing high

"G"

diving maneuvers such

as split-esses and loops.

CAUTION

(THIS APPLIES TO

ALL

R/C AIRPLANES):

If, while flying, you notice any unusual sounds, such

as a low-pitched "buzz," this may indicate control
surface flutter. Because flutter can quickly destroy
components of your airplane, any time you detect
flutter you must immediately cut the throttle and land
the airplane! Check all servo grommets for
deterioration (this may indicate which surface
fluttered), and make sure all pushrod linkages are
secure and free of play. If the control surface fluttered
once, it probably will flutter again under similar
circumstances unless you can eliminate the free-play
or flexing in the linkages. Here are some things which
can result in flutter: Excessive hinge gap; Not

mounting control horns solidly; Poor fit of clevis pin in
horn; Side-play of pushrod in guide tube caused by

tight bends; Poor fit of Z-bend in servo arm;

Insufficient glue used when gluing in the elevator

joiner wire; Excessive play or backlash in servo gears;

and Insecure servo mounting.
