I am measuring interest in my Autel 640T. I absolutely love it. However I bought it with the intention to do some roof survey and solar panel jobs. They have not worked out because honestly I haven't the time to commit. I am working with a couple of emergency service agencies in developing drone programs, so my own stuff is on the back burner. I'd be willing to sell for the right price and upgrade when I come back to my business. I have the fly more combo with the live deck. (YES THE LIVE DECK!) I'll post pictures in a follow up if I find interested parties.
