Name: Rlaarlo Omni-Terminator RZ001 Carbon Fiber Roller
Brand: Rlaarlo
SKU: RZ001T-CROLLER

Also sold as the Rlaarlo RZ001

Rlaarlo's Omni-Terminator RZ001 Carbon Fiber Roller is the four-wheel-drive monster truck without motor, ESC, servo, radio or battery, so the builder chooses the power system.

The 65T spur feeds a differential stage of 3.09, so the final drive is 65 divided by the pinion, times 3.09. It runs 104 mm tires. Choose the motor and pinion together in the gearing calculator, since the pair decides both the top speed and how hot the motor runs.

Tire: 104mm

Sold without a motor, so there is no stock KV: compare gearing by rollout.

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. Monster trucks have tall tires and long suspension travel, built for jumping and rough ground rather than a race track. Drive All four wheels are driven. That gives more grip under power, especially on loose ground. 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 Almost ready to run: built at the factory but missing some electronics, usually the radio and sometimes the motor, ESC or servo. 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. This one is worked out from the tooth counts the maker publishes. 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.

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. At high speed tires can balloon and grow, so the real gearing gets taller as the car goes faster.

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.

Battery	Not applicable
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. Height Overall height as the maker states it, usually with the body fitted. Useful when checking it fits a shelf, a bag or a car trunk. 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.
Derived is worked out from gear tooth counts the maker publishes rather than printed as a ratio; the notes below say how.
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

Roller: motor, ESC, servo, radio and battery are not included, so the KV and cell count are the buyer's.

The manual's configuration table (p. 16) prints a 65T spur (0.53M/48P), an 11T input gear and a 34T differential ring gear, which is 3.09:1 after the spur, worked out from the printed tooth counts.
It gives the tire as 104mm for all three versions.
The pinion is printed only as a 24-27T range, so the fitted pinion and the final drive are left blank.
Rlaarlo prints a 60 to 80 km/h band for the RTR versions, which is a range and not a single claim, so none is shown.
The drive is four-wheel drive with three differentials.
