The Kabolite K988-100S RC Hydraulic Wheel Loader is a substantial radio-controlled construction machine built for enthusiasts who want functional hydraulics, serious lifting capability and the presence of a large-scale RC loader. With its heavy construction, large bucket and detailed operating geometry, the K988-100S is designed to recreate many of the material-handling operations performed by a full-size wheel loader.
At approximately 903 mm long, the loader is considerably larger and heavier than typical hobby-grade RC construction equipment. The supplied specifications place the bare vehicle at approximately 23.5 kg, while another machine-weight specification lists approximately 20–21 kg. Regardless of the measurement basis, this is clearly a heavyweight RC platform intended for substantial operation rather than casual tabletop use.
Its hydraulic system delivers a specified 15–25 kg lifting force, while the bucket provides 1,942 cm³ of capacity. Power comes from a 3S lithium battery system with a stated maximum power output of 83W.
Available through Heavy Duty RC, the K988-100S brings together hydraulic functionality, realistic dimensions and heavy-duty construction in an impressive RC wheel loader package.
What Is the Kabolite K988-100S?
The K988-100S is an RC hydraulic wheel loader designed to perform realistic loading and material-handling operations.
Instead of focusing solely on scale appearance, the model incorporates functional machinery that allows the operator to raise and position the loader arms and bucket. This makes it particularly useful for miniature construction environments where loose material needs to be collected, transported and transferred.
The supplied specifications describe a machine approximately 903 mm long with a substantial operating mass and hydraulic lifting force of 15–25 kg.
Its bucket has a specified capacity of 1,942 cm³, giving the loader the physical capacity needed for realistic loading cycles with suitable materials.
These characteristics position the K988-100S toward the serious enthusiast end of the RC construction market.
Large and Impressive Construction
One of the first things that stands out about the K988-100S is its physical presence.
The product description initially lists dimensions of 903 mm long, 247 mm wide and 296 mm high. A separate basic-dimensions section provides measurements of 903 × 296 × 280 mm.
Because both sets of figures appear in the supplied information, they should not be silently reconciled. Buyers requiring exact clearance dimensions should confirm the current specifications with Heavy Duty RC before purchasing.
The bare vehicle is listed at approximately 23.5 kg. Elsewhere, machine quality is specified as 20–21 kg, while the packaged net weight is given as 25.5 kg.
Whichever measurement applies to a particular configuration, the K988-100S is clearly a substantial RC machine.
That mass can contribute to stability during hydraulic lifting and loading operations, while also creating practical considerations for transportation and storage.
Functional Hydraulic Loader System
Hydraulic operation is one of the defining characteristics of the K988-100S.
Rather than functioning as a simple display model, the loader is designed to reproduce material-handling operations through its functional lifting equipment.
The manufacturer specifies a lifting force of 15–25 kg.
That figure gives enthusiasts an indication of the loader's hydraulic capability, although actual performance can vary depending on the material being handled, bucket position and operating conditions.
Hydraulic functionality allows operators to reproduce a complete wheel-loader cycle: approach a material pile, fill the bucket, raise the loader arms, reverse away from the pile and position the bucket for unloading.
When paired with compatible RC dump trucks, the K988-100S can become the loading component of a complete miniature construction or quarry operation.
Large 1,942cm³ Bucket
The K988-100S has a specified bucket capacity of 1,942 cm³.
Bucket capacity is particularly important on a functional RC wheel loader because it determines how much loose material can physically fit into the bucket during each loading cycle.
The K988-100S's bucket also forms part of a carefully specified loader geometry.
The centerline of the pitch shaft to the tooth tip of the bucket measures 350 mm, while the bucket hitch reaches a height of 401 mm at maximum lift.
The maximum overall machine height with the bucket raised is specified at 555 mm.
These measurements are valuable when planning an RC construction environment, particularly if the loader will be paired with dump trucks.
Maximum Lift Geometry
The loader's dimensions provide useful information about how it operates around other RC equipment.
Clearance at maximum lift is listed at 264 mm, while protrusion distance at maximum lift is 180 mm.
The bucket hitch height reaches 401 mm at maximum lift.
Meanwhile, the entire loader reaches a maximum overall height of 555 mm when the bucket is fully raised.
These measurements should be considered when selecting compatible dump trucks or designing a miniature loading area.
A loader may have substantial hydraulic power, but practical compatibility also depends on whether the bucket can reach high enough and extend far enough to position material correctly.
This makes the K988-100S's supplied loading geometry particularly useful for enthusiasts planning multi-machine RC operations.
Power System and 3S Lithium Battery
The K988-100S is powered by a 3S lithium battery.
Its supplied specifications identify maximum power at 83W.
The product description describes the system as energy-efficient and designed to provide reliable performance during operation.
However, the supplied information does not identify the battery's capacity, connector type, charging time or verified runtime.
These details should therefore be confirmed rather than assumed.
Because hydraulic operation, vehicle movement and other electrical functions can place different demands on the battery, actual runtime can also vary according to operating style.
Speed Range
A speed range of 2,000–5,000 rpm is included in the supplied specifications.
The source material does not explicitly identify which component this rpm figure describes. It should therefore not automatically be presented as wheel speed, motor speed or hydraulic pump speed without additional confirmation.
What can be stated accurately is that the K988-100S specifications list an operating speed range of 2,000–5,000 rpm.
For prospective owners comparing technical specifications, confirming exactly which component this measurement applies to would be worthwhile.
Steering and Maneuverability
The supplied specifications list a maximum turning radius of 43°.
The terminology is unusual because turning radius is normally expressed as a distance rather than an angle. The figure may refer to the loader's steering or articulation angle, but the supplied description does not clarify this.
Accordingly, the safest interpretation is simply that a maximum turning figure of 43° is specified.
Maneuverability is particularly important for an RC wheel loader because loading operations frequently require repeated forward and reverse movements in relatively confined areas.
Operators need to approach a pile, fill the bucket, reverse, turn toward a truck and reposition for unloading.
The loader's steering system therefore plays an important role in creating realistic material-handling sequences.

Packaging and Transportation
A machine this substantial requires equally serious packaging.
The K988-100S is protected using an aluminum-wood composite board box, which is then enclosed inside a corrugated outer box.
The inner packaging measures approximately 101 × 32 × 36 cm, while the outer box measures 102 × 34.5 × 38.5 cm.
Gross shipping weight is specified at approximately 28.5 kg, with a listed packaged net weight of approximately 25.5 kg.
This protective arrangement is important for a heavy RC construction model containing hydraulic, mechanical and detailed exterior components.
Prospective owners should also consider the package dimensions and weight when planning transportation and storage.
Realistic Material-Handling Operations
Where the K988-100S becomes particularly interesting is when it is incorporated into a complete RC construction site.
A hydraulic excavator is designed primarily for digging. A dump truck transports material. The wheel loader provides another crucial function: rapidly collecting loose material and transferring it between locations.
This allows enthusiasts to recreate quarry, aggregate-yard and construction-site operations.
The loader can approach loose material, fill its bucket and maneuver toward a compatible RC dump truck. The hydraulic arms can then raise the bucket before the material is discharged into the truck bed.
Who Is the K988-100S Best Suited For?
The K988-100S is particularly suitable for enthusiasts looking for a substantial hydraulic construction model rather than a lightweight entry-level RC vehicle.
Its size, weight and hydraulic functionality make it particularly interesting for established RC construction collections.
Owners who already operate hydraulic excavators and dump trucks can use a wheel loader to expand the range of activities possible within their miniature construction environment.
Collectors may also appreciate the machine simply for its dimensions and mechanical complexity.
However, its substantial weight means prospective owners should have appropriate storage space and be comfortable handling a heavy RC machine.
Maintenance and Ownership Considerations
Hydraulic RC equipment requires appropriate maintenance to remain reliable.
Owners should regularly inspect hydraulic connections and moving components and follow Kabolite's instructions regarding the hydraulic system.
The loader should also be checked after material-handling sessions, particularly when operating around sand, soil or other loose materials that can collect around moving components.
Battery care should follow the appropriate procedures for the supplied 3S lithium power system.
Because the supplied information does not identify hydraulic oil specifications, service intervals or detailed battery information, owners should consult the manufacturer's documentation rather than relying on assumptions.
K988-100S and Other RC Construction Equipment
The K988-100S can serve as an excellent companion machine to hydraulic excavators and RC dump trucks.
For example, Kabolite's K350-series excavators provide digging capability, while the K988-100S focuses on bulk material handling and loading.
Adding compatible RC dump trucks can create a three-stage workflow: excavation, loading and transportation.
This is one reason larger functional RC construction machines can become increasingly engaging as a collection grows. Each model performs a different job rather than simply duplicating another machine's functions.
