This beacon was bought brand new from Whelen along with an adapter plate about 6 months ago. We bought it to replace the current beacon on our Cessna 170 but we decided to not put it in because it was going to require more work to install than we initially thought. It has only been taken out of the box a few times and tested to be sure it works. Includes the beacon and the adapter plate. PayPal or Venmo only. Pm for questions.
