Inspired by a pilot workshop episode about total electric failure and the use of a backup handheld nav/com, I adapted a holder for a different handheld to my Yaesu FTA-850l, so I can mount it on the dash and not only use it for backup communication but actually use the LOC/VOR/ILS function the handheld provides in an emergency. It's compatible with a diamond base plate you can also 3d print (2x M5 hex nuts + 2x M5 8-10mm screws) or buy.
The author remixed this model.
adapted to a Yaesu FTA-850l and added a few fillets.
