I am a beginner pilot and started using just thumbs. I have started using thumbs and fingers while flying on the sim and I find i have much greater fine control. The only problem I am finding is that the radio needs to be held flat for me to use thumbs and fingers and it is fine sitting in front of the computer with the radio on my lap. Problem is that when I am standing with the neck strap on the radio is weighted more to the bottom so now I think I need a transmitter tray. Anyone know where to get one for a good price? For myself thumb and fingers give better control.
