It doesn't appear to have the long moment arms and hish aspect ratios like the Goldberg Tiger series?
Those features were what made the Goldberg Tigers fly so smooth.
Though the plane in this picture is not a Goldberg Tiger, it is based on one. This one has a G23 engine. I once saw another with a Saito 182.
It was a FG kit made by someone in Tenn. I think? Do not know what its name was?
