I saw someone selling Greg Covey’s Firefly VTOL saying it was purchased from an Estate Sale
I knew he had not been posting for a while so I googled this.
Greg was the most enthusiastic and helpful member of this forum who was always displaying the latest efforts of the Ardupilot devs. He had a fondness for quadplanes. I hate when you find out something like this 7 months later. Greg will be very much missed by many people here.
He will be missed, I will remember him for the excellent quality and professionalism of his many blogs, and the kindness and dedication in the support of these great builds.
Oh, very sad to hear that. I don’t think he let a Vtol>quad plane post question go unanswered. A real guru.
He was a true VTOL,er and help every one sadly missed by all on here
It’s so sad that the best go too soon. The words of
speak from my heart
I took a break from Ardu Pilot and just saw this sad news. I am so heart broken 
Greg was such a wonderful person. He always went out of his way to help others, and his professionalism and mannerism were just amazing. Too bad I couldn’t meet him in person as we tried once.
He will be greatly missed…
Rip. Sorry to hear that. Love his post till today.
I often think of Greg Covey.
He was such a helpful and kind person.
He personally helped me a lot. As said at the start, I often think of him.
I hope his family is doing well and that his family know Greg helped a lot of people he never personally met.
Thank you Greg. You are missed.
