I too recommend the Spektrum DX18. I have a few of them and they work for everything. I am pretty sure that the only differences between the Generation 1 and the Generation 2 are as follows:
-The Gen. 2 has the speech software where the radio can be set up to talk/tell you things (This would benefit someone piloting an airplane or heli in flight).
-The Gen 1 does not have the wireless trainer link (again, for an airplane or heli benefit).
-With software updates they should be the same.

Something that you will have to do on either gen 1 or gen 2, is setting up the left stick to be spring loaded for the up and down movement. They are all set up for airplane and heli throttles, therefore, the stick will not return to the middle position on its own.

Good Luck,
