I'm currently building a plane and would like to invest on a decent transmitter so I've looked towards the Turnigy 9XR PRO that's available for a good price but only without the RF module. I've seen videos of people buying ones from china then doing firmware updates but I was wondering is there just a cheap plug and play option that I can easily connect to a 9ch receiver. If doing it this way, costs too much does anyone have any recommendations for a decent radio preferably 8 channels or above that's under £100.
