This site has a lot of use in the past week or two!
Outside on the asphalt, the 12M Euro really works well. Fast, Smooth and easy to drive. If everything works out, I might be able to win our outside series with it. I'm 1 point back in second after the first 4 events!
As to the battery trays, I thought there was talk last year that Corally was finally going to make a new carrier for the new cells and already cut for 4 cells. I beleive I even saw a part number. Anyone else remember this?
Rinkrat is correct, we have a local R/C fabricator who does great work. I'll race his 12L4 conversion on the carpet this winter and he has been making me T-Bars and other parts as needed. This also included making fiberglass spacers that allows me to use large diff rings on the Corally rear axel. Helps when getting diff controll with 19 turn or modified motors.
As to using Associated style wheels, I have always felt that the Corally rims were stronger, plus the cost is less. Once you have the car set up you will only need a few compounds to make it work. My 2 cents.
I've raced a Corally 1/12 scale for 15+ years.
Where is the 12X???
