As is the new LAK 17c FES https://www.youtube.com/watch?v=rxe6DIfPKb4

More prop clearance, 16s batteries and higher max RPM for 2.5 m/s climb rate. The angle of attack of the wing is smaller, back to what it was on the 17a (vs the 17b that was based on the fuselage of the LAK 19)

These gliders are sustainers only.

Looks like the Silent 2 is rated for self-launch.
As is the miniLak FES, also a 13.5M glider. It works well for them because they are lighter
than the 18M gliders.
