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.

R/C Helicopter Safety / 
A model helicopter must be built exactly in accordance with the assembly instructions. The kit manufacturer has spent
much time and effort refining his 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 buil-
der/flyer and starts with careful construction and continues with selection and installation of reliable radio equipment and
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.
Guidelines for Safe R/C Helicopter Flight
•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.
Warranty Procedures / 
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 is not responsible for any shipping damages. We will, at our discretion notify you of any costs involved
you are required to pay all postage, shipping and insurance charges.

Team 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.
