I didn't model this, I found it at sonic cult Here. The only thing I did here is rigged it for animation (I don't know if anyone els did this). and did a little animation to show that it works.
also I rendered it like that for no real resone, the gif file type did not do that to it, I did. the low color that is.
I know something is up with the hands, but I don't know why...
Edit: I did this in 3Ds max 9 32bit
Update! hands problem found by Mark the Echidna, now its fixed.
here is a new animation.
Update 2!
I've rigged Dami's Classic sonic model now, and quite well I mite add... it was more fun rigging his model than the other one. as always, here is a new animation of Dami's model in action walking.
Update 3!
It took a little extra rigging but I got it, another animation!
