Build Quality and Materials
CNC-machined metal construction
The LESU BL71 hydraulic RC loader is built using a CNC-machined metal shell, ensuring precise detailing and excellent durability. This construction method results in a highly realistic appearance, closely resembling full-size construction equipment.
The use of metal extends across most of the structure, providing a solid and stable platform for heavy-duty tasks.
Durable wheels and tires
The model features aluminum alloy wheels paired with high-quality rubber tires, delivering both strength and traction. This combination allows the loader to operate effectively on various surfaces, including dirt, sand, and gravel.
Hydraulic System and Functionality
Advanced hydraulic system design
One of the defining features of this machine is its fully integrated hydraulic system. It includes:
- Hydraulic oil pump
- Reversing valve
- Switching valve
- Stainless steel hydraulic cylinders
- Overflow valve
This system ensures smooth, coordinated, and precise movements across all functions.
Multi-function front loader
The front section includes a hydraulic shovel and bucket system, capable of lifting, carrying, and dumping materials. The bucket also features a hydraulic opening and closing mechanism, enhancing realism and control.
Additionally, the inclusion of a front fork attachment expands its versatility for different tasks.
Rear excavator arm with extended reach
The rear digging arm is equipped with a multi-axis hydraulic assembly that can move laterally. This allows for a wider working range compared to fixed-arm models.
The digging mechanism is powerful enough to handle realistic excavation tasks in sand and loose soil.
Drive System and Mobility
4×4 drive with differential locking
The 4×4 drivetrain ensures that power is distributed evenly across all wheels. The inclusion of differential locking axles improves traction, especially on uneven terrain.
Optimized gear ratio
The front and rear axles feature a 1:2.7 reduction ratio, which enhances torque and control. This is particularly beneficial for heavy-duty operations such as lifting and digging.
Stable movement across terrains
Thanks to its robust drivetrain and tire design, the loader performs well on:
- Loose dirt
- Sand
- Grass
- Gravel
Stability and Operation
Hydraulic support legs
The model includes hydraulic stabilizer legs, which provide additional support during excavation. These legs help prevent tipping and ensure stable operation when using the rear arm.
Rotating cab seat
A unique feature of this model is the rotating cab seat, allowing the operator to switch between front loader and rear excavator controls easily. This enhances realism and improves usability.
Electronics and Control System
Flysky PL18EV Lite controller
The included Flysky PL18EV Lite radio system offers precise and responsive control. With multiple channels available, users can operate the machine’s complex hydraulic functions smoothly.
Integrated lighting and sound
The loader is equipped with a light system and sound module, adding realism to the overall experience. The rotating beacon light further enhances the construction vehicle aesthetic.
Real-World Performance
Front loader efficiency
The front loader performs well in material handling tasks such as:
- Scooping sand
- Transporting small loads
- Dumping materials
The hydraulic bucket ensures controlled and precise movements.
Excavation capabilities
The rear arm offers impressive digging performance, with smooth hydraulic action that mimics real excavators. The lateral movement feature allows for greater flexibility in tight spaces.
Multi-tasking versatility
The combination of front and rear tools makes this model highly versatile, capable of performing multiple tasks without switching machines.
