WELCOME DOUBLE-XT •cR• OWNER!
Thank you for purchasing the new Team Losi Double-XT ' CR '. This kit has been developed using the latest
technology and design techniques available. Oouble-X technology debuted
of at the '93 IFMAR World Championships,
and proceeded to dominate qualifying. Since then,
the Oouble-X line of cars and trucks have been in a class by
themselves. The 'CR ' takes advantage of countless race winning laps, incomparable design and exclusive composite
materials that
have all combined to make Team Losi famous worldwide. Our goal is not only to make the chassis pe rf orm
better, but also easier to tune for your particular track.
Before beginning assembly
of this kit, please take a moment to read through the entire instruction manual. This will
help minimize building time and get you on the track sooner. You should find our sequential assembly process to be
quick and easy to follow. We have included assembly tips throughout the manual as well as a separate tuning section to
help you
set-up your 'CR' for optimum performance.
Good luck, and thank you
for choosing Team Losi.

KIT/MANUAL ORGANIZATION
The Team Losi Oouble·XT 'CR' is composed of different
bags marked A through H. Each bag contains all of the
parts necessary to complete a part icular section of the
Double·XT 'C R' truck. Some of these bags have subassem-
bly bags within them. It is essential that you open only one
bag at a time and follow the correct sequence, otherwise
you may face difficulties in finding the right part. It is helpful
to read through the instructions for an entire bag prior to
starting assembly.
Key numbers (in parenthesis) have been
assigned to
each part and remain the same throughout the
manual.
For yourconvenience, an actual size hardware iden·
tification guide Is included with each step. To check a part,
hold it against
the silhouette until the correct part is identi·
lied. In some cases extra hardware has been supplied to .

replaceeasilylostparts. Differentfits have
been designed
into plastic parts (i.e. press, net, loose).
To insure that parts
are not lost during construction, it
is recommended that
you work over a towel or mat to prevent parts from rolling
away.
IMPORTANT SAFETY NOTES
1. Select an area for assembly that is away from the
reach
of small children. The parts in the kit are small and
can
be swallo wed by children, causing choking and possible
internal injury.
2. The shock fluid and greases supplied should be
kept out
of children's reach. They were not intended for
human consumption!
3. Exercise care when using any hand tools, sharp
instruments, and power tools

4. Carefully read all manufacturer's warnings andcau·
tions tor any glues or paints that may be used for assembly
purposes.

MOTORS AND GEARING
YourOouble-XT'CR' truck includes an 88 to o th , 48 pitch spur gea r. The overall internal ge a rbo x ratio IS 2.61'1. Theexternal
pin i on gea r will determi ne y our gea r ratio. To figure ou t the final drive rat io first divide the spur gearsize by the p1mon ge ar si ze .
Say y ou are using a 20 tooth pi n io n ge ar, you w oul d divide 88 (spur gear s1ze) by 20 (pimon gear SIZe). For examp le:
(88/20 = 4.4) So 4.4 is y ou r external driveratio. Now multiply the internal drive rauo (2.61) by the externaldnve ratio ( 4.4 ). F or
example: (2.61 x 4.4 = 11.484) This tells y ou th at by us i ng a 20 t oo th p1n1on and a 88 tooth spur gear, the final drive rat io is
11 .484:1.

of the more common motor types and a recommended in itial geari ng lor that mot or. Ra ti os can be adjusted depending on
