Hi Stefan, If you were flying thermals with full aft flaps, that is pretty draggy on a LAK 17. The sweet spot with my 17a was thermal postition 2 and CG about 80+%. In 15 meter mode I could fly all day with a 27 in strong conditions and any slight differences in climb and glide would be insignificant. CG at anything less than 70% would degrade the climb enough to be difficult to climb with other well flown ships. It took me a while to get the best out of my LAK, after several years in a Mini Nimbus - big difference!

Note that 17C airfoil is different compared to 17A, so with 17C is better to thermal with more deflected flaps.

LAK 17 is the most underrated glider, tbh

Thanks for the interesting review, Stefan. Was pleased to see how well you did in the E3Glide beating 3 of the 4 Ventus 3F's. A great achievement in an unfamiliar glider.

While I fly jets for work I might start gliders again. You make it look so fun and I haven't glided in a while so you inspired me. Thank you

I do love your e-glider content. Looks like it's a growing area.

I proud that it was produced in Lithuania! Good glider, isn't? Surprisingly, this my lovelly country has a long-therm aviation history.

Seems a lovely glider. Those wingtip could do with a little more width which might make them more effective. I hope you did well in the competition with it. I enjoyed the views from that canopy. Thanks for the fliers eye view of a competition sailplane. Happy flying, Dave W 😊

Hi Stefan, Another change made to the 17C from the 17B to facilitate self-launching (besides the longer undercarriage for prop clearance) was to alter the angle of incidence of the wing on the fuselage slightly to help with launch phase handling. When the first 17C was flown in comparison flights with a 17B it was discovered that the 17C was better in climb despite having the same wing... Why? Because the new wing/fuselage angle was more efficient at high angles of attack. This caused much mirth at LAK

The LAK is great value for money for most pilots. Being able to choose from 15, 18 and 20m wingtips is fantastically versatile. Hope they get self launch certification soon which will make this glider a very tempting choice

Love your video's. I need to get a ride in one of these some day.

Nice glider. During flying nice playing flute skills. Respekt

Hi Stefan, you are right, that´s may be the future of soaring. Although it is still very expensive.

Using the flaps in the air, how do you decide what position is the best ? Could this manouver be automated somehow? No matter how fancy the meter panel is, tape and the wire remains on the canopy ! :D

Thank you for the beautiful video. Would a 2m tall person, 95 kg, feel comfortable? I am too tall for Schleicher up through the 31. I think high aspect ratio (giving better finesse) improves the winglet performance. However, I am a contrarian on the role of winglets, as I hypothesize that winglets do not significantly improve the wing's finesse (by behaving like some kind of lateral air 'damn'), but instead winglets generate a minor bit of thrust by turing the, wind root directed, spanwise airflow rearward, and in redirecting the airflow, generate a small thrust.

When you often fly with ballast in gliders it seems like an obvious opportunity to use that for batteries and self launch it. As great as gliders are they really need an engine :)

Parabéns pelo voo top , muito bonito.

Great job

I used to own a Lak 12. It was such a lovely aeroplane and it could stay up for ever, and had a min. sink rate of about 95fpm, and L/d of 50:1. It was rubbished by nearly all (most of all by people who had never seen one, let alone flown one). I was just so impressed with it, and never experienced a moment's perspiration in flying it over about 100 hours. I did hit some very nasty ground effect with exceptionally strong sink once on short final, and a measured lowering of the nose kept the airspeed just right. It was a gorgeous aeroplane to own. I used to hangar it, and it was taken apart once a year for its annual inspection. The maintenance engineer, german born and very highly educated in aero engineering and practically experienced was reluctant to take it on because it came from one of those communist countries, and he was schooled in beautifully built german sailplanes, but after the first annual, he reported that the metal work in them was excellent, but he didn't think all that much of the glass work - fine, strong etc. but not so pretty here and there. But it was a very handsome aircraft to the eye, too, with the low mounted stabiliser. Anyway, family and work got in the way, so I sold it most regretfully. If I was looking for an up to date aircraft now, the type I would first look at is a Lak 17b or c. The main problem with the 12, other than blind prejudice, was the weight of the wings - about 210 lbs from memory but three people could take it out of the trailer on quite uneven rubble ground, attach the one man rigging wheel, turn it through 90deg, and slot the wing roots in ... but after that, to close them to the correct fit was a pain, and you certainly needed one man to be strong at that point and it took a bit of wiggling around up and down at the wingtip, which I did and I am as strong as a 10 year old girl. But we only did this a few times, and we could have improved with practice. Hoteliers snapped in perfectly and simply. This talk of needing a rugby team is complete bulldust. Ground handling and towing to the flight line was no problem. It is very nice to be up there in smooth evening air when all the other gliders pilots are pushing their aircraft into the hangar. Lak were certainly making a nice product in the 1990s.

I follow you and I really like your channel so fierce it makes me relax and happy keep doing it I like it

I suspect it would be worth installing solar panels on the wings, it should increase range by about 30%

Awesome video :) I hope someone here can answer my question. What glider pilot license do you need to fly internationally in all these races? Is the ICAO sailplane pilot license the one to get? I’m in Australia and I’m not sure if they offer that here so any advice would be great :) thanks

From the CASA website: Part 61 includes a glider pilot licence (GPL), which is ICAO compliant…. As an ICAO compliant licence, the GPL is expected to be recognised by foreign aviation authorities and this will assist Australian pilots wishing to participate in gliding competitions overseas.

The winglets add drag without accomplishing increased glide ratio or electric range in a glider.

Competitive gliders have water ballasts & negative flaps to help speed up flight while inbetween thermals. Would a new design with variable-sweep wings benefit to further increase speed during certain high-speed runs? Then mechanically switch back to straight wings & positive flaps while thermaling.
