O.S. 21XZ-R Speed & 21XZ-R VII engines
O.S. have introduced two new 21XZ-R engines for 1/8 scale on-road racing with both featuring superb runtime. Engineered for added horsepower and faster lap times, the 21XZ-R Speed performed well at the 1/8 Scale On-Road Worlds in Miami, Florida with Team drivers coming home in 4th and 5th place with production models. The motor features a redesigned crankcase and carb to produce smoother transitions and higher speeds while the 21M slide-valve carb features 4 adjustable control settings, including a low-end metering needle for improved torque and fuel economy. A more-balanced conrod reduces vibration and wear. Equipped with many of the same performance features as the .21XZ-R Speed ABC, the 21XZ-R VII offers explosive acceleration and top-end for race-winning potential at a more economical price. It combines aggressive timing with easy starting so drivers can unleash its race-winning potential right out of the box, while the cylinder liner boasts 7 scavenger ports and three exhaust ports. Both engines are available in early August.

O.S. Speed new concept silencers
Seen during our coverage of the World Championships in Houston, O.S. Speed have released further details on their new line of on road exhaust systems. These new exhausts are fixed to the manifold with a pair of aluminium clamps which prevent the silencer from disconnecting during races. Unlike conventional spring connection, the semicircular clamps enable the adjustment of the pipe to any direction. The pipe itself makes the low to middle range response of the engine more snappy while maintaining top speed power. Available for the .21 (FEMCA & IFMAR legal) and .12 (EFRA & IFMAR legal) engines.

O.S. Speed racing tools
We wrote about these tools back in January when they were first announced but there have been some additions to the range since then, mostly for gas racers. Made from the highest quality materials to the strictest tolerances for superior performance, comfort and reliability, the diamond pattern grips make the driver handles easy to hold, while three flat sides keep tools from rolling off the pit table. Indicating grooves let you identify tip sizes at a glance and each handle has end caps with a rubber O-ring that allows it to rotate in the palm. The tips are made of CNC machined spring steel and can be retracted into the handles for storage, or to adjust for the desired length. The new additions include a clutch nut wrench, a flywheel holder & clutch gap tool and finally a flywheel puller. Available in US in mid-June.
