Here are a couple of photos of an aircraft I built called the Goldberg Mirage 550.
I constructed this Goldberg aircraft sometime in the late 1990s. Even after 20 years, the Goldberg Mirage 550 still performs well. I would even consider this to be one of my best fliers. I am using a Speed 600 brushed motor and a 3S LiPo 1800MaH battery in the Goldberg Mirage 550. I thought you could use the photos in your Goldberg collection.
