Sirio Engines have announced that their new S12 T3 EVO4 STI engines will include ceramic ball bearings in both the front and rear of crankcase. The use of ceramic balls is said to provide better reliability and performance of the engine and these bearings use only the ceramic balls, which makes them also extremely light. Available seperately, they can also be used in all of the company’s S12 T3 engines that have a 12mm crankshaft.
Our US Magazine partners R/C Car have the first pictures of the new Kyosho Stadium truck that was spotted in secret testing at one of the magazines local tracks in Southern California. The RT-5, as it is currently being called, is a 1/10 scale off-road electric stadium truck, which Kyosho reps stress is still highly pre-production and in full testing mode. The RT-5 is based upon Kyosho’s popular RB-5 electric buggy and in fact shares RB-5’s transmission and tranny ratio. The car, as you would expect has a longer chassis, longer suspension arms, and longer shocks than the RB-5 and the double-thick carbon-fibre shock towers seen in the photos are still undergoing testing with production versions perhaps being molded, fibre or carbon fibre. There is no official release date yet, but Kyosho will debut the RT-5 in mid-March at the Cactus Classic in Phoenix, Arizona, where a Kyosho engineer from Japan will join the team to help with further development.

The 16th installment in the Xray column from Xray owner and chief designer Juraj Hudy is now online. In this months column, Juraj talks about the development of the company’s new XB808 1/8th scale buggy, which was shown for the first time at the toy fair in Germany a few weeks ago.
To improve steering and handling in bumpy conditions, I decided to use the suspension concept that has been used for ages in 1/10 electric off-road cars… the “zero kingpin” design. This design seems to work in the 1/8 buggy scale as well and the first prototypes were created for testing. Zero kingpin suspension gives more precise steering and handling in the corners as the steering keeps the same angle no matter if the suspension is up or down, and as such when running through bumps in corner the steering will not change as much as on regular C-hub suspension used previously and the handling of the car will improve significantly.
