judging from the size of the cutout on the CG top deck and the relative size of the receiver box to the gas tank & receiver pack, i'd say you have enough room to fit your XXtra.
contender, see if control centre can special order those parts for you. cuz if they carry kawahara i'm sure they can order it (unless it is not released yet).

LoL, well to each his own. Too many people jumping onto the snake bandwagon. Its a nice looking car but the R40 seems friendlier to get into (HPI parts are usually cheaper and great planes always carries HPI). Plus look at all the options thats gonna be available.
