			Actually any of the new Spektrum radios have all the parts installed.  It's just a matter of taking the back off and adjusting the centering spring and loosening off the ratchet spring.  As well as you need to remove the 2 limiting stops that are installed on the throttle stick.  I've now done this on my DX8, DX9 and DX18.
