Since 2009 we only offer our special, inventive BWS–Flexi-Bugwipers.
According to type of glider the BWS-Flexi-Bugwipers are fixed to the retrieval line below or above the wing.
Below the wing: tilting part and opening spring must be placed on the lower part of the Bugwiper.
Above the wing: tilting part and opening spring must be placed on the upper part of the Bugwiper.

Our PATENTED JOINT automatically adapts the BWS Flexi-Bug-Wiper to the wing profile during the cleaning from wing root to wing tip and back again.
Up to now, for any type of glider a special bending and pressing mould had to be made, causing due to the many types of gliders extremely high production costs.
Yet, by our inventive joint system, hinging upper and lower part of the BWS Flexi-Bug-Wiper together in a flexible, pivotable manner, it is possible for the first time to use only one form for nearly any type of glider. This enables us to use the expensive, but utmost precise injection molding.
The advantages are obvious
In case of order, please inform us whether the retrieval line shall be fixed to the upper or lower part of the bug wiper (according to the position of the retrieval line being above or
below the wing).
Below the wing:
Antares, DG, Hornet, HpH, Jantar, Jonker, Kestrel, LAK, Libelle, LS, PIK, Schempp-Hirth, SZD
Above the wing:
EB28, EB29, Schleicher

Replacement of the cleaning filament:
The free pivoting joints at the front of the bug wiper enable automatic adaption to the wing profile during cleaning along the whole wing.
Please pay attention to the following:
The cleaning filaments should be as long as possible, but short enough that the bug wiper is always sliding on the cleaning filaments and not on the frame. Check this especially at the wing tip. Take also care - only in case of retrieval lines above the wing - that in the collapsed position at the fuselage the cleaning filaments are also short enough to prevent opening to a bigger profile than necessary.
