I would definitely recommend a neckstrap or tray. I don't believe neckstraps are dangerous. I just don't wear mine when I'm starting a plane. Leave it attached to the transmitter and then put it on. A very simple cure for shaky hands is to tighten your transmitter springs. Your hands may be shaky, but it wont translate into any movement of the sticks. In competitions, I sometimes get nervous and the heavy transmitter springs eliminate the bouncing from nervous hands,
