In yet another new chapter, a 1968 Gardan GY80 has been added to the list of interesting vehicles in my life. If I can maintain some discipline, I hope to journal the story of this plane, its history and the journey I take to keep it flying.

As I started researching this plane, before purchasing it…I was inspired by a few connections, content and links to information. Robin has been an absolutely amazing contact and fellow Gardan owner. It’s been great learning from his experience and I hope I can someday do the same for someone else.
