Any word on when the IB4200 (and GP4300) cells will be made legal for sanctioning bodies such as ROAR, ARCOR, etc?

Yea, 2007!!!!!!!

They are legal in Arcor for Open Modified I think. If I am not mistaken there isnt a rule for batteries in this class other than Sub C cells....Unless it has been changed.

For Roar it will be Jan 1 2007 as Jimmy Flack posted.

EA

For ARCOR 3800's in stock and 19T until Jan 1 2007

Arcor -- Open Mod is any sub c cell that make the length requirements set forth in the rules.
