Hi mate 4 channels for the flight of the quad but you need to assign switches for the modes CL/HL/GPS/ATTI/MANUAL so thats 2 x 3 way switches for the modes , why dont you get the Phantom 1 transmitter your even get gimbal control if you fit a camera later on , but the transmitter will have IOC /CL/HL/ATTI/return home and land fail safe and you know its going to work right out of the box , your need to email DJI.com they used to sell them on there site they still do but its not listed any more
If you have no joy I know that it can be set up on a DX6i transmitter
