The GP15 is being test flown in Krosno at the moment and all reports are very positive. Pilot Tomas Kuzmickas has taken it up fully ballasted (59.4kg/m2) and confirms that it climbs well even at that wing loading. The controls are light and positive and the glider is so stable that it can be thermalled hands off – and he has posted a video to prove it!
Argentinian agent, Felipe Girado, hit it lucky and got himself a flight in the GP15 while at the 2018 WGC at Ostrów. He came away very impressed. His report can be found via our Facebook page.
