We realised that when designing a racing car, it is not only about how fast the car is, how much steering it has, or how much acceleration it has, but more about controlability and handling. We learned that we need to place more emphasis on the driver, and the experience of driving the car. The car should feel like it wants to be driven, and it should inspire confidence in the driver. After all we all race because we enjoy it, and we all want to win, so our goal is to make driving at your maximum pace, as much of an enjoyable experience as possible.

We are constantly developing our race cars in an effort to provide you with the best possible vehicles. We are updating our guides and articled regularly, so please do check back from time to time. We share what we learn with you, because we believe it helps us all enjoy RC Racing more!

O.S. SPEED B21 Adam Drake Edition 3 is developed in collaboration with O.S. international team driver ADAM DRAKE, who is famous for his deep knowledge and sound technical advice.
By adopting a boost bypass processing for the crankcase, the engine runs more smoothly, and making it even easier to drive. ADAM DRAKE's image color, blue anodized aluminum is applied to the cutting part of the new outer head, and two-color anodized aluminum with new design is used to reduce weight and lower the center of gravity improving driving performance. You can choose two different carburetor restrictors, 6.5II for buggy and 7.5 mainly for truggy.

Spec:-
Displacement： 3.49cc / 0.213 cu.in.
Bore: 16.4mm / 0.646 in.
Stroke: 16.55mm / 0.652 in.
Output 2.65 ps / 2.61 hp / 34,000 r.p.m.
Practical RPM range: 4,000-42,000 r.p.m.
Engine Weight: 350g / 12.35oz

• By adopting a boost bypass processing for the crankcase, the engine runs more smoothly
• ADAM DRAKE's image color, blue anodized aluminum is applied to the cutting part of the new outer head, and two-color anodized aluminum with new design is used to reduce weight and lower the center of gravity improving driving performance.
• In addition, by adopting a cover plate with a built in thrust plate, wear due to interference between the connecting rod and the cover plate during rotation is reduced and engine life is improved.
• The inner head uses an O-ring to reduce vibration and improve dust resistance.
• Blue anodized restrictors, 6.5mm for buggy and 7.5mm for truggy comes standard.
