Team Associated's RB10 Factory Team Retro Kit is a 1/10 two-wheel-drive buggy kit with an aluminum tub chassis.
Its 2.6:1 gearbox provides the fixed part of the final-drive calculation. The stock spur and pinion remain unrecorded here. Check the actual gears supplied with the kit and choose the motor and tires before comparing theoretical speed.
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.
Buggies are low, light off-road cars built for jumps and fast corners on dirt, clay or turf tracks.
Drive
Only one axle is driven, the rear on almost every 2WD RC car.
It is lighter and simpler, and it takes more throttle control on loose ground.
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.
This one is 400 mm long.
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.
Differentials
The type of each differential, as the maker states it.
A gear or ball diff lets the wheels on one axle turn at different speeds in a corner; a spool or locked diff turns them together for straight-line drive and climbing, at the cost of steering.

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.
Wheel hex
The hex on the axle that the wheel locks onto and is driven by. A wheel must match the hex size to fit.
12 mm is the common size on 1/10 cars, so most 1/10 wheels fit; offset and width still vary.
The wheel nut is a separate size, so check its thread too before buying nuts.

Suspension
Chassis
What the main chassis is made of and how it is built, as stated for this car. Braces, stiffeners and skid plates are not counted.
Aluminum is stiffer than composite, which keeps the handling consistent; it can bend in a hard crash, and a bent chassis is usually replaced rather than straightened.
A tub is one molded piece with raised sides that hold the parts and keep dirt out.
Shocks
What the shocks are and how they are built, as the maker describes them.
Oil-filled shocks damp with silicone oil; friction shocks, found on some entry-level cars, damp with a sprung plunger and cannot be tuned with oil.

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.

Performance
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.

Size & weight
Length
Overall length as the maker states it, usually with the body fitted.
Useful for comparing real size, since scale labels are loose.
Width
Overall width as the maker states it, usually with the body fitted.
A wider car is more stable in corners and harder to roll over.
Wheelbase
The distance between the front and rear axle centers. A longer wheelbase is steadier at speed and over bumps; a shorter one turns more tightly.

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, or does not have one, like a KV rating on a brushed motor.
Not published means it exists but no source we could find prints it.
How these numbers were settled
Rear-motor buggy kit with a 2.6:1 gearbox and ball differential.
Motor, electronics and tires are purchased separately.
The kit has an aluminum tub chassis and 13mm Kashima-coated shocks.
