Thanks for the info guys. Does the shrink wrap (or lack thereof) around the Electrolytics have anything to do with this revision?

I noticed that on every Mamba Max out there, even the ones pictured in the ads on various online hobby shops, have a shrink wrap wrapped around all three of the electrolytic capacitors. My unit never came with a shrink wrap around the three capacitors. Is this a sign of an older version or the new revision?
