RE: Thumbs or 2 finger?
I just hold it and use my thumbs. Part of that is because I use my DX5e to control my touring car, where a neck strap would just get in the way, and part of that is I've always held stick radios like that since I was three years old playing with my dad's Frog way back when those were huge. I've tried the strap-and-pinch method with my heli and it just feels awkward, not to mention the heli looks like it's pilot has consumed three bottles of Smirnoff when I do that.
