21 years after first flight , our Gryf granddaddy is still flying, and we are very satisfied with its flying characteristics. Of course it is not ideal for cross-country flights, it does not have range above 1000 km like MD3 Rider - but show me something better for flying "around the hangar" . To help twenty users around the whole world, we would like to offer free of charge some ULM-1 documentation in Gryf - airplanes corner. Maybe somebody can build that from these drawings - but be carefull, aircraft is very good flying, but very expensive for identical building. Remember, that time we produce that by great aircraft producer technology - without to know true expenses ...
