Flying Circus Tissue band issue

[IckyATLAS]

On the Spad and the Fokker there is a long tissue band that is fixed on the top right wing.

When the plane is sitting parked this tissue band is just dangling vertically. When you start the engine nothing happens.

This is not correct. With the strong air flow coming from the propeller it should move up maybe 50 degrees and not stay fully vertical. At full throttle and rolling or flying then it is straight horizontal.
