The return thread of the bug wipers can damage sealing tapes. Here is a simple trick to prevent this.
Due to the wing geometry of the Ventus, it can happen in certain situations that the return thread jams in the sealing tapes interrupted by the kink. It can then tear them off when the bug wipers are retracted.
If you simply connect the gap with a sticker, you can prevent this. On the photo you can see at which position you should perform this simple trick.
