O.S. Speed B2102 .21 Low Profile Off-Road Nitro Engine
This is the O.S. Speed B2102 .21 Off-Road Nitro Engine. The innovative B2102 engine comes equipped with a low profile head which provides great influence to the running performance. The low-profile cooling head (-17mm) makes the vehicles center-of-gravity much lower, which improves car handling drastically without sacrificing cooling performance.
The B2102 also comes equipped with the O.S. 22C (B) carburetor for improved fuel mileage to go the distance; ten-minute runs on a single tank are no longer a privilege of top drivers with magic fingers.
