A FLZ version of this glider which I started from a WIK design which after finding factory drawings turned out to be very scale.
The original Eppler e195 was compared and replaced with the with the NM 32, a profile intended to improve the performance of the famous HQ profiles which are legion on large flap or non-flap gliders. This profile may be a little thick for this scale especially at the tip where the original had a 9% e174. Scaling the design up to 1-4 should be relatively easy in FLZ-Vortex.

Inspired by a French design in Model Magazine with an updated Wing Planform and Airfoil. The Pod and Boom fuselage came out really well, and the modern Clark Y "Strak" looks good in XFLR5.

This time a VEB Cirrus from 1974 with updated wing geometry, Ailerons and profiled Empennage.
The original e374 was replaced after some comparison on BigFoils Similarly shaped airfoils and in XFLR5 with the SB98 VR-S5 series. The Venkataraman airfoil fit producing the final smooth airfoils.
With any luck it might make for a nice VTPR Glider when built.

Inspired by Mike Trew's design on Outerzone I modelled a modern version with EM Airfoils and slightly broader wing tips. The Washout is scale, however the tips still look "interesting" . I also included the original airfoil if anyone wants to test 19% thickness at 1-5th Scale .

A .flz simulated Swift with a HN-951 " Strak" as recommended and tested from another forum. Fuselage side and top came out really well.

A digital copy of the original from WIK with the e393 airfoil "Strak" as discussed here.

To convert the .dat files to accurate .dxf I can recommend the open source Profil Converter.

A digital recreation of my favourite Slopie from the Nineties.
The .flz file can be opened with http://flz-vortex.de/flz_vortex.html and exported to .dxf etc.

A 2 meter Model I designed in FLZ and Profile Editor.
The airfoil was smoothed with Venkataraman fits from www.bigfoil.com.
