Looks like it would fit. The Zippy H are some of the biggest cells in terms of physical size and therefore some of the biggest packs around. My 3s just fits into my Slash without an extension kit for height and they are listed at 160 x 51 x 24mm. So provided those dimensions are correct within a couple of mm you should be able to drop that 4s pack into a Rustler as long as you can get or make a hold down for it.
