The Flysky GT3B is the best radio for the buck for any rc. The dx3e is very cheesy to me, 3 pos switch is in a horrible spot, no display, only one model memory.
Gt3b is cheap, has more functions, display, feels good in your hand, and has several model memory slots. Plus rx's for them are like $10-15 instead of $35-90 for the spektrums.
