Still get nervous once in a while after 15 yrs., but a tray helps me. I was always nervous holding the transmitter. Hard for me to hold the xmtr and make precise inputs. Things get sweaty in Alabama in the summer. After I got a tray, I could relax(and concentrate) more with nothing pulling on my neck and the tray holding the xmtr. Also try putting the fuzzy part of peel and stick Velcro on the back of the xmtr. Better than slick plastic. If you can relax with the xmtr., that is one less job to do while flying.
