The Jacobs Hols der Teufel (English: Devil take it) was a single seat trainer glider produced in complete and plan forms in Germany from 1928.

[1] The next machine to be named Hols der Teufel was designed by Lippisch and Hans Jacobs in 1928, possibly with the assistance of Alexander Schleicher.

[2] The Jacobs plans show the Hols der Teufel had a simple, constant chord wing much like that of the Zögling though of greater span, built around two spars and fabric covered except at the leading edge which was plywood skinned.

Its leading edge was straight and strongly swept; the cropped, parallel chord elevators had a central cut out for rudder movement.

[2] The ready availability of detailed plans and the fact that with its low wing loading the Hols der Teufel was one of only a few training gliders with the soaring capability to take a pilot to a C-badge resulted in widespread amateur construction worldwide, though overall numbers are hard to establish, not least in Germany.

[2] The Slingsby Kadet was the result of a conscious "crossing" of the low wing loading soaring performance of the Hols der Teufel with the better handling of the Prüfling, particularly by improving the former's poor lateral control with better ailerons.
