It is quite easy to order Corally parts via the internet ( http://www.rccarinternational.com ), and the wheels and espacially the tires glued to the rims are quite cheap. I think thats an advantage of the Corally cars, but after all I run an Associated. But to get the right tires for Associated is not so easy for me and they are very expensive. Do you have a source where to buy JACO cheap via the internet?
About the 12M: we had some serious discussion obout this car recently but ended in ordering the old G3. This car is a proven design and has (allways in 6 cell modified format, dont have any ideas about 4 cell racing) some advantages over the Associated. With the 12M Corally wanted to improve especially the asphalt/outdoor performance, wich is not an issue here. Last but not least until now there is no 6 cell carbon fibre saddle pack version available.
This are all just my personal opinions, but I still would go for the CRC if running 4 cell.
I heard about a class raced in Japan: 6-cell stick packs. Does anybody know something about it? Does anybody have mor info on the recently held Japanese 1/12 national championship?
