The factory have recently announced that following the success of the Mini LAK FES with EASA certification expected soon, they have started production of their latest design, the LAK 17C FES.
Mindaugas Žaliukas, who flew some of the early prototype test flights, commented:
"The performance of the glider is impressive. It climbs very well with and without water ballast. Piloting is easy and does not require superb experience or too much concentration.
I flew the LAK 17C after a 6 year break. During this period, I flew the JS1C, AG29 and the HpH 304cz which are considered the best in the market and are a pleasure to fly.
I was sceptical about the performance of the C prototype, because I could not believe that the changes in the aerodynamics could make such a difference in the performance, especially thermaling. But I was wrong…
We flew a 300 km task in very different weather conditions. I had to soar from low altitudes (250-300 meters) in very week, like 0.2 m/s and strong (4 m/s) thermals. I had to fly long distances between the clouds. Twice I had to cover over 40 km holes and I did it at a speed of 120 km loosing less than 1000 meters! There were no thermals in the holes, and it means that the L/D is realistic. I had no water ballast and some bugs on the wings…
I think the LAK 17C has bright future as a competitor in FAI 18m Class".
The LAK 17C FES is an 18m electric self launching sailplane. It has a modified undercarriage to provide sufficient ground clearance for the folding propeller and a revised angle of incidence at the wing root, which, together with a number of other aerodynamic changes has resulted in even better handling and an increased climbing performance. The lithium battery capacity has been increased and the FES electric motor has a higher rpm limit.
