when we first got the xb4 we found over rotation an issue hence the range that we now offer for the car, the xb4 has proven to be very solid in all hands wears well and is easy to drive (although a touch aggressive for some hands) and quick enough to make national A finals, although i have voted to wait and see what comes after the worlds, there were 6 proto cars there, at least 3 of these will be realeased in the near future according to reports, i know that as soon as the d413 arrives there will be a solid team running the car and working very hard to find uk base setups for most tracks. the ralls racing section will have its own setup page for the car to provide easy to find info on top of this
. if you cant wait for the new ones then grab a second hand bargain to tie you over
