Sold without a motor, so there is no stock KV: compare gearing by rollout.
Background
The MTC2 is a 1/10 four-wheel-drive touring supplied as an assembly kit.1 The mid-drive touring chassis uses long suspension arms and a tapeless battery mount.1 The instruction manual provides the assembly sequence and identifies the equipment the builder must supply.2 Gearing and equipment choices depend on the installed engine or motor and the track surface. The supplied chassis needs completion and setup before it can be driven.

Check the kit's required-equipment list when selecting the parts needed to complete the vehicle.2
Pros
The kit manual documents assembly and component installation.2
Cons
The builder must supply the required radio and power equipment before running the vehicle.2

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
Sold without a motor, so you choose the motor, ESC and battery yourself.
Rows that depend on the motor say so.
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
The small gear on the motor shaft. Fewer teeth gear the car shorter: quicker acceleration, lower top speed and a cooler motor. More teeth do the opposite.
It depends on the motor you fit, so the maker does not list one.
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.
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.

Power
Motor
Motor KV is the RPM a motor turns per volt with no load.
This vehicle comes without a motor, so there is no stock KV; it depends on the one you fit.
Battery
The highest LiPo cell count the maker rates the electronics for.
This vehicle comes without electronics, so it depends on the ESC and motor you fit.

Theoretical top speed
It needs a motor KV, and this vehicle comes without a motor. Fit one and the calculator works it out from the motor's KV and the gearing.

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 applicable means the vehicle does not come with it, like the motor on a roller or the tires on a race kit.
Not published means it exists but no source we could find prints it.
We have not collected a parts list for this exact model. Check the manufacturer documents in Details.
About these specs
The required-equipment list includes both spur and pinion gears, motor, ESC, body, tires and wheels. Select these separately; there is no kit-standard total drive ratio.
