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. has introduced the new OS Speed B2104, a long-stroke .21 offroad engine, featuring quicker response in the low range and more torque in the middle range, along with consistent idling. The new piston/liner is a conventional 3-port type enabling more torque over the power range, while the new crankshaft has DLC coating and two tungsten counterweights embedded in the crankshaft contributing to consistent idling and quick return to idle. The boost port and the exhaust port of the crankcase are redesigned for optimum airflow, while the rest of the engine remains familiar with the use of 22E type carburetor and conventional round-shape cooling head with standard height. Also available as part of a combo with the TB03 (T-2100, EFRA 2155) silencer with 80mm manifold.

Features

• The new piston/liner is conventional 3-port type enabling more torque over the power range.
• The new crankshaft has DLC coating as we always do for OS SPEED engines. The two tungsten counterweights are embedded in the crankshaft contributing consistent idling and quick rpm down according to throttle move.
• The thrust plate with surface treatment embedded in the cover plate reduces friction against a connecting rod to extend its life.
• The boost port and the exhaust port of the crankcase are redesigned for optimum air flow.
• The carburetor is trustable 22E type, which we have been using for B2103 Type R.
• The cooling head is conventional round-shape type with standard height.
