Turnigy 9XR/9XR-PRO Thumb StyleTransmitter Tray

thingiverse

I wanted a tray to hold my 9XR-Pro steady but didn't want one that wouldn't allow me to fly thumb style so I came up with this design which gives me the best of both worlds without costing a fortune. Requires 2x M6x30mm bolt/screws, 2x M6 nuts, 2x M6 washers and 2x M3x15mm bolt/screws. Thread the M3 bolts into the thumb screws and secure with some CA glue. The frame can then be bolted to the back of the radio by using the existing bolt holes in the back of the radio. The add the front plate insert which holds the edges of the radio's "feet" to keep the front stable. This just needs to hold things steady so not too tight but once in place a drop of glue on the tabs will keep it solid. The arms can then be attached by threading the M6 bolt and washer through the arm, inserting the M6 nut into the cutout and screwing them in from the outside in. Don't go too tight until you have tested the fit - it needs to hold on but not be fully tight. Try the radio on for size and adjust the angles of the arms to suit your own preference. Once you're happy with the angle, add a drop of glue to the arm to tray join and tighten the bolts down fully. I used a double ended neck strap from a holdall bag for this but any strap with two clip ends will work.
