The O.S. Speed B21 AD3 Adam Drake 3 Competition .21 Nitro Engine is the latest evolution of this potent racing engine. Designed in collaboration with the legendary Adam Drake this AD3 edition features several updates and improvements over the already competitive B21 engine platform. The AD3 uses an updated crankcase inner design for linear power making the transition from low to middle to high speeds almost seamless. Adding to this is an updated backplate with a steel lining reducing resistance and aiding in not only extra power but better fuel mileage. Helping to keep weight in check a freshly designed cooling head features a 3mm lower height and is 14g lighter overall lowering the engine's center of gravity and shedding weight in a critical area.

Featuring a semi-long stroke configuration, this engine boasts a DLC crankshaft with larger double tungsten counterweights and a unique cylinder design that’s exclusive to the Drake edition engines. These changes will provide smoother low end power and more overall torque than the previous model. The AD3 is an excellent choice for both buggy and truck racing as it provides a linear power band, exceptional fuel mileage and tons of overall power.
