Overview of the Rovan 1/5 Scale 5B Baja Buggy
The Rovan 1/5 Scale 5B Baja Buggy with camo green body delivers powerful large-scale gasoline performance with proven durability and serious off-road capability. Powered by a genuine 29cc air-cooled two-stroke engine, this Rovan 1/5 Scale 5B provides strong torque, responsive throttle control, and stable handling across dirt, gravel, and open terrain. As a result, it remains an excellent choice for racing, bashing, and high-performance off-road driving.
These are Genuine High Strength Grade A Rovan 5B models. They are not factory seconds, not downgraded, not knockoffs, and not outdated versions. Every Rovan 1/5 Scale 5B supplied through 5TRC is built with current-generation components and quality-controlled hardware.
Size, Scale, and Chassis Design of the Rovan 1/5 Scale 5B
Built to true 1/5 scale proportions, the Rovan 1/5 Scale 5B offers an aggressive stance and excellent stability at speed. The chassis measures approximately 32 1/8 inches long, 18 7/8 inches wide, and 10 inches high, which helps keep the buggy planted during high-speed runs. In addition, the 22 3/8 inch wheelbase and wide front and rear track widths support predictable handling and balanced weight distribution.
Structural Layout and Reinforcement
The chassis is engineered to absorb punishment while protecting critical drivetrain components. Second-generation reinforced suspension mounting points flex under impact instead of cracking. Because of this design, the Rovan 1/5 Scale 5B handles rough terrain and repeated impacts with reduced risk of structural damage.
Engine and Drivetrain Performance of the Rovan 1/5 Scale 5B
Power comes from a genuine 29cc single-cylinder, air-cooled two-stroke gasoline engine engineered for reliability and strong low-end torque. In stock configuration, this engine delivers 40 MPH plus depending on conditions while maintaining dependable operation. As a result, the Rovan 1/5 Scale 5B balances performance with long-term durability.
Exhaust and Power Delivery
A tuned exhaust pipe improves throttle response while producing an aggressive exhaust note. An 8,000 RPM clutch manages power delivery efficiently, allowing drivetrain components to handle high loads during acceleration.
Differential and Drive System
The Rovan 1/5 Scale 5B uses a rear-wheel-drive layout with a rear axle brake for controlled stopping power. A strong drivetrain combined with reinforced components ensures consistent power transfer during aggressive off-road driving.
Suspension, Wheels, and Handling Characteristics of the Rovan 1/5 Scale 5B
The suspension system plays a major role in how the Rovan 1/5 Scale 5B performs off-road. Carefully selected components balance durability with predictable handling.
Suspension System and Shock Design
Second-generation reinforced front and rear suspension arms work with 6mm shocks to absorb impacts effectively. Because the suspension compresses smoothly, the Rovan 1/5 Scale 5B maintains traction over uneven terrain. In addition, this setup reduces chassis roll during cornering.
Wheels and Tires
Second-generation wasteland tires mounted on second-generation hubs deliver consistent grip across mixed surfaces. As a result, the Rovan 1/5 Scale 5B remains stable during acceleration, braking, and cornering.

Assembly and Operation of the Rovan 1/5 Scale 5B
Out of the Box: Ready to race once the wheels are installed and the car battery has been charged. Minimum 2 hours charge recommended.
Battery Charging
The car features a charging plug and comes with a USB charger. No disassembly required for charging. Allow battery to cool down for 30 minutes after full charge before operation. Remove charger within 30 minutes of full charge (green light) to prolong battery life. Store battery fully charged. Recommended Countdown Timer: https://shorturl.at/FdYdP
Crash Durability
Minor crashes are unlikely to cause significant damage. These Rovan 1/5 Scale 5B buggies are tough and designed to handle aggressive off-road driving.
Fuel Mixing Requirements for the Rovan 1/5 Scale 5B
Uses a 25:1 gasoline-to-oil ratio (151.4 ml per gallon). Fill the small compartment of the mixing jug to the 25:1 line with oil, then fill the gas compartment to the same line. Use non-synthetic, mineral-based 2-cycle oil. Other suitable brands may also be used.
Radio Setup and Adjustments
This six-channel radio essentially only uses two channels with the Rovan 1/5 Scale 5B. Trim adjustments are located under the cover on the back of the radio. The top left controls steering trim, the top right controls throttle and brake trim, the bottom left adjusts steering control extents, and the bottom right adjusts throttle control extents.
Starting Instructions for the Rovan 1/5 Scale 5B
Ensure the car and radio are powered on and responding.
Set the choke on the right side of the car (red lever on the carburetor) to the vertical closed position.
Press the primer bulb on top of the carburetor 3 to 4 times, or once fuel is visible.
Gently pull the starter rope until it engages, then pull swiftly. Do not pull the rope out completely; use short quick pulls.
Crank until the engine fires (usually 1 to 3 pulls).
Turn off the choke, then pull the rope 1 or 2 times to start the engine.
Never crank more than 3 times with the choke on.Break-In Process for the Rovan 1/5 Scale 5B
Initial Run: Start by running the car at idle to 1/4 throttle or less for about 5 minutes. Let the engine cool down completely after this run.
Second Run: Repeat the same process for 10 minutes, then allow it to cool.
Third Run: You can start pushing it a little harder, but keep in mind that a new engine generates more heat due to increased friction. Run for 8 to 10 minutes, then let it cool.
Subsequent Runs: Continue the process for about five runs, being mindful of any debris that could block cooling. A clean engine runs cooler.
Final Break-In: After these runs, you can run the car at full throttle and let it burn through an entire tank of fuel.
Post-Break-In: Be sure to check and snug up the exhaust pipe after the initial break-in process.
Before each run check bolts throughout the car to ensure they are tight. Lock-tight is recommended on clutch and brake assembly bolts. Clean bolts and holes with alcohol and a Q-tip to ensure proper lock-tight adhesion.
You will be tempted to upgrade some of the parts to aluminum. However, aluminum is unforgiving and can break while damaging surrounding components. High Strength ABS Plastic flexes and bounces back without damage, which is why many plastic components perform better in off-road conditions.
