K18, very nice. I managed 200k in one a few years ago. It was a Talgarth K18 that went swimming in Lake Lingham in December -the pilot ran out of ideas and daylight about the same time and decided a water landing would be better than trees. When they went to retrieve it the following day, it was undulating in the waves; the glue had softened a bit.....nevertheless somebody took it on and rebuilt it...
