I using a IX14 with spirit gt and some with spirit 11 and pro is there a way to-get air speed read out on my transmitter what do I need to purchase . I am not running a geo-link .

.... you'll need the Spirit Geolink unit - this will give you airspeed and a lot more (of course - depending on the telemetry system and cabling you are using - there would be the possibility of using some airspeed sensor (pitot tube)... would not save a lot of money and not give any of the great features of the Geolink. besides the mounting on a heli of a pitot tube can be tricky - and you'll get speed for forward flight only... not always great for helis)
