The XRAY M18 Micro is a unique 1/18th micro-sized model racing car
that is the epitome of high-performance and fine distinctive design.
Your M18 offers highest performance, responsive handling, and
traditionally exceptional XRAY quality, engineering, and design.
The XRAY M18 enters a new frontier in micro-car design by offering
fully-adjustable suspension, responsive shaft-drive drivetrain, and
ultra-smooth gear differentials. The superb craftsmanship and
attention to detail are clearly evident everywhere on the XRAY M18.
The XRAY M18 was created by blending highest-quality materials and
excellent design. The result? A very affordable, durable, high-
performance micro race car that is extremely easy to assemble, drive,
and race. On high-speed asphalt tracks or short twisty indoor tracks,
whether driving for fun or racing to win, the M18 delivers outstanding
performance, speed, and precision handling. M18 can be used for
competition micro racing, but is also well suited for novice drivers who
choose the XRAY M18 as their entrance into the R/C hobby.

R/C TIPS
QUALITY CERTIFICATE
• Read and fully understand the instruction manual before building.
• Always keep this instruction manual ready at hand for quick
reference, even after completing the assembly.
• Make sure all screws are tight. Check them periodically.
Make sure that the chassis screws do not protrude from the chassis.
• For the best performance, it is very important that great
care is taken to ensure the free movement of all parts.
• Clean all ball-bearings so they move very easily and freely.
• Tap or pre-thread the plastic parts when threading screws.
• Self-tapping screws cut threads into the parts when being tightened.
• Do not use excessive force when tightening the self-tapping screws,
or you may strip out the thread in the plastic. We recommended you
stop tightening a screw when you feel some resistance.
• Ask your local hobby shop for any advice.
• Please support your local hobby shop. We at XRAY Model Racing
Cars support all local hobby dealers. Therefore we ask you, if at all
possible, to purchase XRAY products at your hobby dealer and give
them your support like we do. If you have difficulty finding XRAY
products, please check out www.teamxray.com to get advice, or
contact us via email at [e-mail], or contact the XRAY
distributor in your country.
XRAY MODEL RACING CARS uses only the highest quality materials,
the best compounds for molded parts and the most sophisticated

purchased kit are manufactured with the highest regard to quality.
However, due to the many factors inherent in model racecar competition,
we cannot guarantee any parts once you start racing the car.
We wish you enjoyment of this high-quality and high-performance
micro car and wish you best success on the track!
In line with our policy of continuous product development, the exact specifications of the kit may vary. In the unlikely event of any problems
with your new kit, you should contact the model shop were you purchased it, quoting the part number.
