RE: what to look for in a transmiter
I actually have the JR 7 channel that came out with the DX7. The only reason I did not choose the DX7 is because I already had three planes and I did not want to buy all new receivers. All I had to do is set my radio to the receivers I already had. Also the JR holds more planes than any out there. I got the heli version, the only difference is the throttle, it is smooth not clicky(I fly planes). For the money I would say the JR 7 if you have a fleet already if not get the DX7.They are almost the same price. You will not have to upgrade ever unless you are really trying to get into larger scale planes that require more than 7 channels.
