This is my first post ever but I thought I would throw in my two cents worth. With 30 years of buying transmitters I had 8 at one time, 6 aircraft and 2 heli's. Then I wanted to try 3d heli and the radio wouldn't handle it as I needed 5 point adj so I got the futaba 9cah. I now have one Transmitter, all on the same freq, 6 planes and 4 heli's. If you are going to stay in the hobby then buy a higher end transmitter and never buy another one again. Make sure to get a heli transmitter in case you ever want to try heli's as they work great with planes also.
