When I was in training, I didn't use a strap. It wasn't until I started learning Pattern Flying that I tried using a neck strap, and found it was so much easier to concentrate on what I was doing rather than worrying about dropping the transmitter, or having the added weight in my hands. My flying became much smoother and nowadays, I find it a challenge to fly without my neck strap. I've tried a tray as well, and I like the idea of just being able to concentrate on my flying, but it does feel a bit cumbersome sometimes. Overall, my neck strap is one of the easiest ways to improve my flying skills, and I would recommend them to everyone if I could.........

But thats just my thoughts...................
