I also have a futaba 6ex, but it has no ppm mode on so have no idea as to how this is going to work.  I have just started in this hobbie and getting a bit long in the tooth, but the instructions seem to be for people who already know about flying aircraft or heli's, how about an idiot guide, think i will be taking phoenix back to the shop who told me my futaba will work , also purchased the square lead that they said i would need, seems as though there is a marketing error when phoenix state will work with ALL futaba Tx's
