Ground Check

If the engine is new, follow the engine manufacturer’s
instructions to break-in the engine.
After break-in, confi rm
that the engine idles reliably, transitions smoothly and rapidly
to full power and maintains full power—indefi nitely. After you
run the engine on the model, inspect the model closely to
make sure all screws remained tight, the hinges are secure,
the prop is secure and all pushrods and connectors are secure.

Range Check

Ground check the operational range of your radio before

the fi rst fl ight 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 (if using a 2.4GHz radio system, refer to
the radio manual for the range checking procedure). 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 fl y! Find and correct the problem fi rst. 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, or a damaged receiver crystal from
a previous crash.

ENGINE SAFETY PRECAUTIONS

Failure to follow these safety precautions may result
in severe injury to yourself and others.

• Keep all engine fuel in a safe place, away from high heat,

sparks or fl ames, as fuel is very fl ammable. Do not smoke
near the engine or fuel; and remember that engine exhaust
gives off a great deal of deadly carbon monoxide. Therefore
do not run the engine in a closed room or garage
.

• Get help from an experienced pilot when learning to operate

engines.

• Use safety glasses when starting or running engines.

• Do not run the engine in an area of loose gravel or sand;

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

• Keep your face and body as well as all spectators away

from the plane of rotation of the propeller as you start and
run the engine.

• Keep these items away from the prop: loose clothing, shirt

sleeves, ties, scarves, long hair or loose objects such as
pencils or screwdrivers that may fall out of shirt or jacket
pockets into the prop.

• Use a “chicken stick” or electric starter to start the engine.

Do not use your fi ngers to fl ip the propeller. Make certain
the glow plug clip or connector is secure so that it will not
pop off or otherwise get into the running propeller.

• Make all engine adjustments from behind the rotating

propeller.

• The engine gets hot! Do not touch it during or right after

operation. Make sure fuel lines are in good condition so fuel
will not leak onto a hot engine, causing a fi re.

• To stop a glow engine, cut off the fuel supply by closing

off the fuel line or following the engine manufacturer’s
recommendations. Do not use hands, fi ngers or any other

body part to try to stop the engine. Do not throw anything
into the propeller of a running engine.

LITHIUM BATTERY HANDLING & USAGE

WARNING!! Read the entire instruction sheet included with
your battery. Failure to follow all instructions could cause

permanent damage to the battery and its surroundings,
and cause bodily harm!

ONLY use a Li-Po approved charger. NEVER use a

NiCd/NiMH peak charger!

NEVER charge in excess of 4.20V per cell.

ONLY charge through the “charge” lead. NEVER

charge through the “discharge” lead.

NEVER charge at currents greater than 1C.

ALWAYS set charger’s output volts to match

battery volts.

ALWAYS charge in a fi reproof location.

NEVER trickle charge.

NEVER allow the battery temperature to exceed

150° F (65° C).

NEVER disassemble or modify pack wiring in any

way or puncture cells.

NEVER discharge below 2.5V per cell.

NEVER place on combustible materials or leave

unattended during charge or discharge.

ALWAYS KEEP OUT OF REACH OF CHILDREN.

AMA SAFETY CODE (

DWB DQOSR

)

Read and abide by the following excerpts from the Academy
of Model Aeronautics Safety Code. For the complete Safety
Code refer to Model Aviation magazine, the AMA web site or
the Code that came with your AMA license.

General

1) I will not fly my model aircraft in sanctioned events, air

shows, or model flying demonstrations until it has been proven
to be airworthy by having been previously, successfully flight
tested.

2) I will not fly my model aircraft higher than approximately

400 feet within 3 miles of an airport without notifying the

airport operator. I will give right-of-way and avoid flying in the
proximity of full-scale aircraft. Where necessary, an observer
