Track-tested performance from the O.S. Engine OS-1A301

The O.S. Engine OS-1A301 stands out as a precision-built choice for RC car and buggy racers seeking consistent power and tuning flexibility. Built for competition, this engine balances responsiveness with reliability to help you stay competitive on the circuit.

Improved carburetion for longer running time

A redesigned carburetor on the OS-1A301 improves fuel metering and efficiency, allowing drivers to achieve around ten minutes per tank under typical conditions. That extra runtime reduces pit stops and keeps you focused on lap times.

Compact cooling head for lower center of gravity

The low-profile cooling head drops the vehicle center of gravity by 17 mm, which sharpens cornering and overall handling without sacrificing cooling performance during sustained runs.

Compact weight with a broad usable rev band

With a displacement of 3.46cc and bore and stroke of 16.40mm, the OS-1A301 produces up to 2.61HP at 34,000rpm and operates usefully from 4,000 to 42,000rpm. At 347g it keeps rotating mass low for improved chassis balance.

The O.S. Engine OS-1A301 is engineered to give racers a blend of fuel economy, power, and lower center of gravity, making it a practical upgrade for both on-road and off-road competition.

How much longer will one tank run with the new carburetor?

Under typical race tuning the improved carburetor helps achieve roughly ten minutes per tank. Actual time will vary with gearing, track layout, and driving style.

Do I need to change cooling practices with the low-profile head?

No special cooling routine is required. The compact head maintains effective heat dissipation, but check temps after early runs and tune your fuel mix if needed.

What electronics pair well with this engine?

Use high-torque servos and a quality glow ignition system suited to 3.46cc class engines. Properly matched gearing and a reliable muffler like the T2090SC will help extract consistent performance.

Is the OS-1A301 suitable for racing buggies and touring cars?

Yes. The OS-1A301 is intended for both buggy and car layouts, offering a flexible rev range and weight that fit many competitive setups.
