R/C Helicopter Safety
A model helicopter must be built exactly in accordance with the assembly instructions. Compass Model Ltd has spent much
time and efforts refining this product to make it reliable in operation and easy to build. Vibration and stress levels are high and
all fasteners and attachments must be secure for safe operation. Safe operation is the responsibility of the builder/flyer and
starts with careful construction and continues with selection and installation of reliable radio equipment and motor/engine.
The need for safety is nowhere greater than at the flying field. A number of guidelines for safe flight have been developed by
experienced flyers and are set down here. It is urged that they be read, understood and followed.
each country has his own security application which cannot be laid down here so prior to any flight request the
rules to apply in your country/Flying field.
Attention:
The radio-controlled model helicopter contained in this kit is not a toy, but a sophisticated piece of equipment. This product
is not recommended for use by children. Radio-controlled models such as this are capable of causing both property damage
and/or bodily harm to both the operator/assembler and/or spectator if not properly assembled and operated. Compass
Model Ltd. assumes no liability for damage that could occur from the assembly and/or use/misuse of this product.Although
theAtom 500 is powered by a quiet, smooth-running electric motor, it should be assembled and operated with the same care
as its larger glow engine counterparts.When operating yourAtom 500, please exercise caution and safety.
• Fly only at approved flying fields and obey field regulations.
• Follow frequency control procedures. Interference can be dangerous to all.
• Obtain assistance from experienced pilots.
• The Guidance provided by experienced pilots is valuable and sometimes necessary.
• Know your radio. Check all transmitter functions before each flight.
• Be aware that rotating blades are very dangerous and can cause serious injury.
• Never fly near or above spectators or other modelers.
• Do not fly r/c helicopter models near buildings, high voltage cables, trees or other obstacles.
• If a beginner, get help trimming the model first and flight training later.
• Don’t “track” the main blades by holding the tail boom. This is a temptation to builders who cannot hover yet and is very dangerous.
• Follow all recommended maintenance procedures for model, radio and motor.
• Only turn off the radio after the engine is shut down.

When first opening your Atom kit, you will notice that all of the parts are packaged and numbered to coordinate with the
assembly step numbers of this instruction manual. All small hardware (nuts, bolts, washers, etc.) for each step are packaged
separately within the main parts bags. When beginning a section, you will need to open only the bag with the corresponding
number to the section you are about to start. It is suggested that you place all of the hardware in an open container (e.g., servo
case) during assembly so as not to lose any of the small parts. It may also be helpful to familiarize yourself with the various
sizes of screws, bolts, nuts, etc., as illustrated in the appropriate assembly section before you begin assembly. In most cases, at
the end of each assembly section, there should be no parts remaining. Great care has been taken in filling the bags with the
correct quantity of parts and hardware for each section. However, occasional mistakes happen. In the event that you find a
parts shortage or are in need of technical assistance, please contact your local Compass Model parts dealer.

Gear BacklashAdjustment:
For smooth operation and
performance, it is necessary to adjust
the Gear Backlash properly. Excess
Gear Backlash can cause premature
Gear Wear and damage. Insufficient
Gear Backlash can cause vibration,
as well as overheating of the Motor
and Speed Controller.Adjust the Gear
Backlash by placing one piece of
paper between the Gears to set the
distance. When the Bolts are secure,
remove the paper and test the Gear
Backlash to insure that there is a
slight amount of free movement
between the gears.
Check the correct rotation of the
Tail Rotor Blades. The Blade on
the Top moves to the rear. If the
Tail Rotor rotates incorrectly,
simply pull out the main shaft and
twist the Belt in the other
direction.
Lift the Main Shaft Collar upwards and
secure to the Main Shaft by slightly
tighten the Lock Screw. It is necessary
to align the Lock Screw through the
hole in the side of the Main Frame.
While securing the Lock Screw, make
sure that you are pushing down on the
Main Shaft so that there will be no
up/down play in the Main Shaft once
the collar is secured.

Compass Model Ball Links are build up on
the tight side this allows you to adjust them
to your personal needs. For this we suggest
to use a Ball Link sizing tool.
The Atom 500 total pitch range is
about 26°. If you set the pitch too high
than flight time will be shortened.
