ZAC tuning Novarossi N12LLT3
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.
