ASSEMBly MAnUAl
The Assembly Manual contains several sections. The first section details the assembly of the
X
ST 4WD Truggy RTR. Detailed drawings in
a step-by-step format make it easy to disassemble and reassemble the
X
ST 4WD Truggy RTR. This is useful when it’s necessary to
replace damaged or worn parts or when it’s time for a complete tear down for cleaning. The second section lists all of the replace-
ment parts that are available for purchase. For your convenience, a drawing of each replacement parts pack is shown, along with a
description and the XTM Racing order number. The third section is a list of option parts that are available, in the same format as the
replacement parts.
When it comes time to order replacement parts and option parts, we recommend ordering directly from your local hobby
retailer.
If your hobby retailer does not stock XTM racing products, contact your closest distributor for a local dealer, using
the Customer Service Information on page 3.
