I was on youtube and saw a video of this guy walking around talking with a bunch of guys at the RCX show I think? I didn't see a good close up, but it wasn't big at all (good

) and there was a fan on it (mah

).
At this point I am strongly thinking about getting one for my Revo, and using my Quark for my other maxx truck.
Here is link... at 2:55, he shows the MMM Revo (supposedly) (EDIT: 2:55 SORRY!)
