INSTRUCTIONS

Serpent’s long tradition of excellence extends to the instruction manuals, and this instruction manual is no
exception. The easy-to-follow layout is richly illustrated with 3D-rendered full-color images to make your
building experience quick and easy. Following the instructions will result in a well-built, high-performance
race-car that will soon be able to unleash its full potential at the racetrack. The kit includes bags, with

bagnumbers, which refer to the same step in the manual. Open only the indicated bag(s) per step and nish

that part of the assembly. Remaining parts will be needed lateron in the assembly process.

plaSTIC paRTS

The Serpent moulded parts are very durable and hard. When assembling longer screws in new composite
parts, make sure to use new hex bits in your (power) tools. Pre-threading also helps to avoid screw damage.

SETUp

In certain assembly steps you need to make basic adjustments, which will give you a good initial setup
for your Serpent Spyder SRX2 MH. Fine-tuning the initial setup is an essential part of building a high­performance racecar like your Serpent Spyder SRX2 MH.
