Description
Rofun WLT450 Red 45cc 1/5 Scale 4WD Gas RC Truck
Red WLT450 Overview
The Red WLT450 is a large 1/5 scale hobby-grade RC truck powered by a 45cc two-stroke gasoline engine. This red Rofun truck combines full-time four-wheel drive, three differentials, a reinforced aluminum chassis, metal drivetrain components, and heavy-duty suspension for demanding off-road operation.
This truck arrives nearly ready to run. Install the wheels, charge the onboard battery, install the required transmitter batteries, add properly mixed gasoline and two-cycle oil, and complete the recommended engine break-in process before full-throttle operation.
45cc Engine and Exhaust
The Rofun WLT450 uses a 44.99cc dual-ring, air-cooled, two-stroke gasoline engine secured by a four-point mounting system. A Walbro 1107 carburetor, NGK CMR7H spark plug, electronic ignition, and heavy-duty pull starter provide reliable starting and responsive power delivery.
A built-in R2 stainless steel silenced exhaust system supports efficient exhaust flow while reducing engine noise. An 8,000 RPM wear-resistant clutch provides controlled engagement, while the metal clutch cup support cover and one-piece hexagonal clutch plate reinforce the drivetrain.
Chassis and Drivetrain
A 5mm CNC one-piece 6061-T6 hard-anodized aluminum chassis provides a strong foundation and resists flex during acceleration, braking, cornering, and hard landings.
The full-time four-wheel shaft-drive system sends power through front, center, and rear differentials. Front CVD half shafts, rear axle-style drive shafts, metal differential components, and reinforced center supports help manage the torque produced by the 45cc engine.
Suspension and Braking
Large 7mm front and rear all-metal hydraulic shock absorbers help control suspension movement over rough terrain. Front and rear anti-roll bars improve stability during cornering and high-speed direction changes.
CNC metal front and rear support beams, shock supports, steering supports, and a center differential cover reinforce critical areas. Dual-disc differential braking delivers strong and balanced stopping power.
Body and Roll Cage
The red polycarbonate split body gives the truck a bold racing appearance. An easy-to-remove full protective roll cage shields the engine, fuel system, electronics, and drivetrain during rollovers and impacts while allowing convenient access for maintenance.
Electronics and Controls
The included 2.4GHz multi-channel radio system provides responsive steering, throttle, and brake control. Heavy-duty 60KG metal-gear servos with CNC metal servo arms operate the steering and throttle-brake systems.
A rechargeable 6V 4500mAh onboard battery powers the receiver and servos. The truck includes a charging plug and USB charger, allowing the battery to be charged without disassembling the vehicle.

Assembly and Operation
Out of the Box
Ready to race once the wheels are installed and the onboard battery has been charged. A minimum two-hour charge is recommended before the first run.
Clear Unpainted Bodies
For unpainted clear bodies, paint the inside using Tamiya polycarbonate PS paint for proper adhesion and durability. For a deeper metalflake appearance, apply a very light coat of clear and then sprinkle a glitter additive, metalflake, or pearl while the paint remains wet. Back it with your preferred colors for a stronger finish. Practice first on a scrap piece of plexiglass.
Battery Charging
The truck features a charging plug and includes a USB charger. No disassembly is required for charging. Allow the battery to cool for 30 minutes after reaching a full charge before operating the truck. Disconnect the charger within 30 minutes after the green full-charge light appears to help prolong battery life. Store the battery fully charged. A recommended countdown timer can help track charging time.
Crash Durability
Minor crashes are unlikely to cause significant damage. These trucks are tough, but responsible operation and routine inspections are still required.
Fuel Mixing
Use a 25:1 gasoline-to-oil ratio, equal to approximately 151.4ml of oil per gallon of gasoline. Fill the small compartment of the supplied mixing jug to the 25:1 line with oil, and then fill the gasoline compartment to its corresponding 25:1 line.
Use non-synthetic, mineral-based two-cycle oil. We have had excellent results with Evinrude Johnson Premium TC-W3 Mineral Two-Cycle Oil, UPC 745419363093. It helps minimize carbon buildup and reduce spark-plug fouling. Other suitable mineral-based two-cycle oils may also be used.
Radio Controls
The included multi-channel radio primarily uses two channels with this truck. The four adjustments located beneath the rear radio cover control the following functions:
- Top left: Steering trim
- Top right: Throttle and brake trim
- Bottom left: Steering control extent
- Bottom right: Throttle control extent
Starting Instructions
- Make sure the truck and radio are powered on and responding correctly.
- Move the red choke lever on the right side of the carburetor into the vertical closed position.
- Press the primer bulb on top of the carburetor three or four times, or until fuel becomes visible.
- Gently pull the starter rope until it engages, and then pull it swiftly using short, quick pulls. Never pull the rope completely out.
- Continue until the engine fires, usually within one to three pulls. Never pull more than three times with the choke closed.
- Open the choke and pull the starter rope one or two additional times to start the engine.
Important: Never pull the starter more than three times with the choke closed. Refer to this starting guide for additional help.
Break-In Process
Initial Run
Run the truck at idle to no more than one-quarter throttle for approximately five minutes. Allow the engine to cool completely afterward.
Second Run
Repeat the process for approximately ten minutes, and then allow the engine to cool completely.
Third Run
You may begin increasing the throttle slightly. A new engine produces additional heat because of increased internal friction. Run it for eight to ten minutes and allow it to cool completely.
Subsequent Runs
Continue this process for approximately five runs. Check regularly for grass, dirt, or other debris that could restrict engine cooling. A clean engine runs cooler.
Final Break-In
After completing the gradual break-in runs, the truck may be operated at full throttle through a complete tank of fuel.
Post-Break-In Inspection
Check and tighten the exhaust pipe after the initial break-in process.
Before every run, check bolts throughout the truck to make sure they remain tight. Threadlocker is recommended on clutch and brake assembly bolts. Clean the bolts and threaded holes with alcohol and a cotton swab before applying threadlocker to ensure proper adhesion.
