and older with previous experience building and operating RC model racing cars. This 
is not a toy; it is a precision car model. This model racing car is not intended for use 
by beginners, inexperienced customers, or by children without direct supervision of 
a responsible, knowledgeable adult. If you do not fulfill these requirements, please 
return the kit in unused and unassembled form back to the shop where you have 
purchased it. Before building and operating your NT18T, YOU MUST read through all 
of the operating instructions and instruction manual and fully understand them to get 

the maximum enjoyment and prevent unnecessary damage. Read carefully and fully 
understand the instructions before beginning assembly.

Make sure you review this entire manual, the included engine instructions, and examine 
all details carefully. If for some reason you decide the NT18T is not what you wanted or 
expected, do not continue any further. Your hobby dealer cannot accept your NT18T kit 
for return or exchange after it has been partially or fully assembled.

Contents of the box may differ from pictures. In line with our policy of continuous 
product development, the exact specifications of the kit may vary without prior notice.
