LDRC 18401 PRO is a 1:18 RC crawler with FOC brushless drive, oil-filled shocks and metal drivetrain parts

LDRC 18401 PRO is a compact 1:18-scale RC crawler that combines slow, technical driving with a more powerful sensored brushless drive. The model features 4WD, a FOC sensored brushless motor, metal drivetrain parts, oil-filled shocks, fully proportional control and functional LED lights.

This is not an extremely fast RC car. Its purpose is controlled driving over obstacles and more realistic behavior at low speeds.

FOC sensored brushless motor

The most interesting feature is the FOC sensored brushless drive.

FOC stands for Field Oriented Control. In practice, it allows the ESC to control the brushless motor more precisely, which is especially useful at very low RPM.

This is essential for a crawler. The car needs to slowly “crawl” over obstacles without jerking or suddenly surging forward.

1700 KV motor and 10 A ESC

Available technical specifications list approximately:

• 1700 KV sensored FOC brushless motor,
• 10 A ESC,
• 9 g servo.

This combination is aimed more at precise control than high speed.

Maximum speed of approximately 15 km/h

The manufacturer lists a maximum speed of around 15 km/h.

That would be slow for a typical RC car, but it provides enough reserve for a crawler to move between obstacles.

The model’s greatest value lies in slow driving.

Metal upgrades in the PRO version

The PRO version uses several metal parts:

• CNC axle parts,
• front CVD drive shafts,
• metal driveshaft,
• ball bearings.

This increases mechanical durability compared with an entirely plastic hobby-grade construction.

Oil-filled shocks

The chassis has oil-filled shocks.

Oil-filled shocks provide more controlled axle movement than basic spring shocks without damping.

For a crawler, it is important that the wheels follow uneven surfaces and the body does not bounce unnecessarily.

Soft tires and good articulation

User reviews highlight the soft tires and the chassis’s large range of movement.

It is precisely the combination of soft tires, 4WD and a sensored motor that makes the model interesting for rocks, wooden obstacles or a home crawler course.

Realistic lights

The model has functional:

• headlights,
• turn signals,
• taillights,
• hazard lights,
• reverse lights.

For a 1:18-scale model, this is a nice detail that adds to its realism.

7.4 V / 500 mAh battery

The car uses a 7.4 V / 500 mAh Li-ion battery.

The stated run time is approximately 30 minutes or more, depending on driving style.

Charging takes approximately 120 minutes.

Some retail packages include one or two batteries, so check the contents of the specific variant before buying.

Range of approximately 20 meters

The controller operates at 2.4 GHz and the stated range is approximately 20 m.

That is sufficient for a 1:18-scale crawler. The car is small, and from farther away it would be difficult to accurately judge the wheels’ position.

Dimensions

The model measures approximately:

• 27.5 cm long,
• 12.2 cm wide,
• 13.5 cm high,
• 155 mm wheelbase.

It is therefore also suitable for indoor courses.

RTR means ready to run

The 18401 PRO is sold as RTR – Ready To Run.

After charging the battery and putting two AA batteries in the transmitter, the model is ready to drive.

Main LDRC 18401 PRO specifications

What do users say?

Users mainly appreciate the value for money and the chassis. Reviews repeatedly praise the FOC brushless system, soft tires and suspension.

Those are exactly the features that matter more in a crawler than maximum speed.

Is the LDRC 18401 PRO worth it?

If you want a small RC car for technical driving, the 18401 PRO offers an unusually good set of features: sensored brushless drive, 4WD, oil-filled shocks and metal parts.

It is not suitable for someone who wants to drift or drive at 60 km/h. But for fans of slow driving over obstacles, it makes a lot of sense.
