Not exactly revolutionary but i like what Kawahara are doing with their ZAC Project tires, which you can now buy in a box set of 5, which not only saves you money but gives you a great little tire box to use along with it. This system of packaging will be available for all their tyres including both the 1/8th and 1/10th scale versions, now i wonder if Novarossi, who import these tires into Europe, will do the box set too?
ZAC Project, the Japanese RC Manufacturer, has released a very limited edition run of 30 hand tuned motors. Based on the Novarossi N12LL3 high end competition motor, ZAC have added a new taller engine head for better cooling, tear dropped and worked the Liner as well as polished and balanced the crankshaft. This is a pretty serious motor and if you dont live in Japan or havent pre ordered one you probably wont be likely to get one.
You can see some more pictures of the work done here.
