Thank you for choosing the Sport X and welcome to Compass Model. The Sport X has been designed to offer outstanding
performance. Same as other compass products, Sport X is powerful, stable, agile as well as accurate. The frame layout has
been designed to create an extraordinarily rigid platform which is both durable and further improved control accuracy. The
simple layout features light weight, low parts count and raise the center of gravity. Please read the complete manual before
assembly. Please take careful note of all precautions and assembly tips. Please also keep the manual as a reference for part
numbers and reassembly following maintenance.
Warranty Procedures
Mail all warranty information within 15 days of original purchase date. If service is required, send the component in
question (if not missing) together with a photocopy of your bill of sale and an accurate description of the problem and part.
Ship components fully insured and prepaid. Compass Model Ltd is not responsible for any shipping damages. We will, at our
discretion, notify you of any costs involved, or ship it COD. You are required to pay all postage, shipping and insurance
charges.
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 flying field has its own sets of safety guidelines which cannot be expressed here, so prior to any flight, refer
to the guidelines at your 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. The 3D
Plus is a large glow powered model, it should be assembled and operated with special care. When operating your 3D Plus,
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.

Use Bearing Retainer
When first opening your 3D Plus 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.

Tip :
Check tail rotor direction.
Top rotor blade moves to
rear
At this point you will notice that the
belt twists 90 degrees as it runs
trough the tail boom. Care must be
taken to assure that the belt is
twisted in the correct direction. The
key to this is to make sure the tail
rotor rotates backward when the
main rotor rotates in the proper
direction. If the tail rotor rotates
incorrectly, twist the belt in the other
direction.

Crimping Belt damages the Tensile Cords
and will result in premature failure.
Be careful not to over tighten the
Bolts when attaching the Tail Rotor
Blades. The Tail Blades should be
able to move with a slight amount
of resistance within the Tail Blade
Holders.

The following Linkage lengths indications are basic values. PLEASE BE AWARE THAT THEY COULD VARY
depend on used Servos and Arms. Some fine adjustments are still needed in following setup steps.
Compass Model Ball Links are designed to
be tight; this allows you to adjust them to
your personal needs. We highly suggest the
use of a ball link sizing tool.
Do not apply plier to resize
Ball Links. Pliers could
cause hidden damage to
Ball Links and result in
failure when operation.

For any radio setup please refer to your radio
instructions first.
The data's shown above provide some general suggestions
for radio setting. This information varies according to types
of main blades, motor, pinion gear and engine. Adjustment
has to be made during the actual flight.

Turn on the radio, set throttle to middle position for 0 degree. Use the subtrim in radio program
to adjust all the servo to get control horn to the right angle. Then adjust the links from servo to
the L Arms (2 on outside of frame and 1 in the middle of the frame) so that the L arms are all
Horizontal.

Make sure that the Flybar Control Arms and Paddles are in line as shown in the diagram.

By adjusting the Links between Swashplate and Mixing Arms set the Mixing Arms to a 5° downward position.
Adjust the Links between the Mixing Arms and the Main Blade Holder to set the Main Blade Pitch to 0°.

At the low throttle stick and throttle trim, the carburetor hole should be completely close. At full throttle stick,
carburetor hole should be completely open. Adjust the ATV in radio, or/and the control horn position on the
engine to achieve above requirement. Make sure the servo does not bind at any traveling point.

Team Tips
General:
It is very important to make sure the clunk line does not get hung up inside to fuel tank. Remove the
fuel tank from the helicopter and rotate the tank. Be sure the clunk can get close to all corners of the
tank.

Leave About 0.1mm space between the Flybar Collar and the Flybar Holder, this avoids the Flybar to snap
when flying.
It is vital not to over tighten the Main Gear Bolt, or it can cause the Autorotation Gear to slightly warp. This
can cause a premature Belt failure, or reduce the lifetime of the Belt.
It is very important to resize the Ball Links for smooth travel, especially on the tail; because issues like tail
wag, sluggish tail, or inconsistent Piro-rate will occur.
