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 finish 

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 Natrix 750 EVO. Fine-tuning the initial setup is an essential part of building a high-performance 

racecar like your Serpent Natrix 750 EVO.

- Be careful when operating the car. Stay away from any rotating parts such as wheels, gears and 

transmission. Stay away from motor, engine and exhaust pipe system or speedo during and immediately 

after use, as these parts may be very hot. We advise to use protective hand cloves.

- Only operate this car in a safe environment, like a special racing track or a closed parking lot. Avoid using 

this car on public roads, crowded places or near infants.

- Before operating this car, always check the mechanical status of the car. Also check that the transmitter
