RE: Transmitter trays
I have tried a lot of trays, either at shows or at the field. For some reason the ones with the straps around my neck are uncomfortable for me. The ones with the aluminium hangers, like Third Hand or Spring-Air are much more comfortable.
For now, I hold the TX between the heels of my hands and use thumb and forefinger. Will probably get a tray in the next few years.
