Background

The Natrix 750 EVO is a four-wheel-drive, 1/10 GP touring-car kit built for on-road racing. Its assembly manual covers the front differential, belt-driven transmission and two-speed clutch system, with optional components kept separate from the build steps. Serpent manual (opens in a new tab).

Spec	Value	Basis
Vehicle
Class The kind of vehicle the maker sells it as. It sets what the car is built to do and which cars it is fair to compare it with. Touring cars are 4WD on-road cars for asphalt and carpet tracks, often raced in classes with fixed motor and battery rules. Drive All four wheels are driven, which puts power down more evenly and keeps the car steadier accelerating out of corners. The cost is more parts to maintain. Power A small two-stroke engine running glow fuel (methanol, nitromethane and oil). It needs fuel, a glow igniter and some tuning. It has no motor KV or battery rating. Build A kit you build yourself from parts. Most kits come without motor, ESC, servo, radio and battery, and many without tires or a painted body. The manual lists what to add. Scale The maker's nominal size compared with a full-size vehicle. It works more as a class label than a measurement. A 1/10 monster truck is far bigger than a 1/10 touring car, so compare length and weight for real size. Part number The maker's product number for this exact version. A V2, a new color, or a kit instead of an RTR usually has a different number, and parts can differ between them. Check it against your box or receipt before ordering parts.

Drivetrain
Pinion On a nitro car the gear on the engine is the clutch bell. Its teeth work like a pinion's: more teeth gear the car taller, for more top speed and slower acceleration. Spur The large gear the pinion drives. A bigger spur with the same pinion gears the car shorter. Pinion and spur must have the same pitch, or tooth size, to mesh. On a nitro car the clutch bell drives it. Transmission & axle Every reduction after the spur, multiplied together: transmission, differentials and axle gears. It is fixed by the design; the gearing you change is the pinion and spur. Final drive How many times the motor turns for one turn of the wheels. A higher number is shorter gearing: more acceleration and pulling power, less top speed. On-road racers often compare gearing by rollout instead, because tire sizes differ between cars.

Wheels & tires
Tire diameter The outside diameter of the mounted tire, tread to tread. A taller tire covers more ground each turn, which gears the car taller. Race tires wear down over a day, and a smaller tire gears the car shorter.
Tire diameter	Not published
Power
Motor An engine has no KV rating. Nitro engines are sized by displacement in cubic inches, such as .21. Battery An engine car has no drive battery. A small receiver pack or a BEC powers the radio and servos.
Motor	Not published
Battery	Not published
Performance
Theoretical top speed An engine has no KV, so a theoretical top speed cannot be worked out from the gearing alone.
Theoretical top speed	Not published

How to read these figures

Stock is as the vehicle ships.
Calculated is worked from the stock figures on this page rather than stored beside them, so the two cannot drift apart.
Not published means it exists but no source we could find prints it.
