How to do a full mod on your 9x
This guide describes how to do a full mod on a unmodified 9x transmitter, adding the ability to have removable stock FlySky, FrSky & DSM2/X modules. Completing all the mods at the same time may not the best approach if you don't have much experience with general electronic work. Ideal would be to do one mod at a time and make sure it works before doing the next, but it easier do parts of the different mods while you have the transmitter taken apart.
