RB have developed handy tool set for working with .12, .21 and .28 engine bearings, both front and rear. Removing the front bearing is now very easy and smooth with this special tool and it also allow you to fit both the front and rear bearing into the crankcase of your engine, whatever the size and brand. For high accuracy, this tool has been made from ground steel and the set comes supplied in a plastic box with the instruction manual. Fit all the engines with the following diameters, 11.5, 12, 13, 14, 14.2 & 14.5mm. The rear bearing extraction still requires the previously available RB tool.

O.S Speed have released the next incarnation of their World Championship winning buggy engine with the release of the 21XZ-B. This 3-port engine features smoother power delivery and an 8% improvement in fuel efficiency. The motor sports a new hardened and lightened crankshaft that uses tungsten weights for balancing, and this is mounted inside ceramic bearings for reduced rolling resistance. The cooling head has also received some attention, being lowered by 9mm and lightened through the use of holes to help lower its centre of gravity.

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.
LRP have announced the release of their Z.21R Spec.3 pull start engine. This performance optimised motor offers great power delivery and is a great replacement engine for existing .21 RTR engines featuring a special timing for even more power compared to its forerunner. Supplied with the LRP PowerCarb 14S-2 carburetor makes it easy to start and easy to set-up.

HPI have released their Nitro Star F3.5 Pro engine, which has been developed especially for off road racing. The HPI engraved oversized cooling head has been drilled and lowered over the crankcase for maximum heat dissipation and keep the weight as low as possible, fitting on top of a separate Turbo combustion chamber. A finned black-coated crankcase design not only adds strength and rigidity but will also help cool the engine. The F3.5 Pro is a 5 port 3.49cc ABC engine and has been optimised for performance and durability without compromising on run time. Tested with the HB and HPI Racing teams with great success this is an engine that can win at the highest level at a price that’s ultra competitive.
Max Power have released the WC edition of their XXL3, which won the World Championships earlier this month in Houston, Texas in the hands of Ralph Burch. The motor features a crankcase with a new sleeve position and shape of the fuel inlet, new light cooling head with Texas logo and WC graphics, new style button with precise fitting and o-ring for preventing dust entering the motor and preventing vibrations of the cooling head. The 3 port EFRA legal piston sleeve set has a new wrist pin piston height, while the lightweight piston itself has been CNC machined from a silicon aluminium compound. A balanced siliconed shaft sports a new super torque timing setting, while a new insulated carburetor makes for super consistent tuning and makes it easy to restart in all temperatures.
