Well....post a weight of the 808 then! I haven't weighed an 808 yet. Ready to go with out fuel here are some weights from my scale:
rc8 -about 7lb 12oz
8ight-about 7lb 10oz
Jammin x1x- about 7lb 14.5oz
GS cl-1 (advanced?)-about 7lb 15oz
Mugen MBX 5R-about 7lb 12oz
Obviously lots of variables, but you get the idea. The MBX-6 is supposed to be around 7lbs 6oz ready to go with out fuel from what I saw on Neo Buggy. My Jammin is lighter than any of those above though
