Who you calling old???? There are quite a few retired aerospace engineers here in FL.... I've got my registration number on the battery. When you lose your drone in FL you find dead people while you are looking for it. At least that happened to one guy recently. Of course that might be better than finding it sitting under a 20 foot python or Anaconda waiting for the owner to arrive (they have found both here in FL).
I'm interested to see if Jason finds his drone. I've seen several stories here where even though the GPS data shows the location, they still can't find the drone. I think the bright orange or yellow florescent color might be the right thing to have. Might be able to spot it with another drone.
