RE: Röga Dalotel
Congratulations on getting your hands on a classic! According to a 1991 catalog from my LHS, the UNO is different in that it's designed for lower drag. Must mean it's more like a pattern plane and less like a scale model. The 2000, 150 and even the .20 size "pico" are very similar but the Uno looks a little less like a scale Dalo,
