This is myself about thirty years ago, with my Free Flight gliders (no radio or control whatsoever, as the name implies: they had to fly by themselves..) ...
They were absolutely identical, but were trimmed in a quite different way: the yellow one had a C.G. at 75% of the chord (yes, different than a real plane..), and was used in calm conditions, while the blue one had a C.G. at 50% and was used in the (often...) windy conditions of Sardinia.
They were designed by myself and built from scratch. Good times, those times...
