ill tell you this

i have a tc3 and an pink ofna box and a hardcore chassis....
alignment sucks when you have the wheel that turns the flywheel sitting perpendicular to the sides of the pink box.
its more of a pain in the ass than its worth.

my friend has the blue ofna box and although his sits on the box the "other way" it still is hard to line up.

i bought mine used, and it came with a t/a black starting box, and it is perfect for the job...i even had a ad to sell it because i had the pink one, but i like it so much better than the pink i might sell the pink box.
too bad the black one wont start my buggy or i woul dsell the pink one
