While in the Czech Republic still a few weeks ago, I had the chance to visit Zbraslavice airfield and do some gliding way before anyone in Finland would even think of starting the gliding season. Of course the weather was not so good that day so I only did one short flight with a local teacher in the L-23 Super Blanik.
The Blanik is certainly a different beast than the modern DG-505 I had flown before. Aluminium construction, not so perfect ergonomics, no high tech gadgets to help you. But I liked it and it was an unique opportunity to have a flight logged in my logbook in another country before I even have my license :)
Short video of an aerotow start there, it was my first time experiencing that as well:
