refinishing Ventus 2cm- wing profile

SH does not publish their airfoil data, or glide polars for that

The Ventus airfoil has changed in subtle ways since the 1981 a/b model
introduction.
The most notable changes have been a sharper leading edge and a
thinner profile near the wingtip,
which showed up on the V2a/b and C models. Take Bob's advice and sand,
smooth, and polish.

Note also that the airfoils (even on the original
Ventus) are tailored for the Reynolds number change
towards the tip. One well-known expert measured the
coordinates near the root and just scaled them down,
reprofiled the wing using the (incorrect) airfoils
near the tip, and reported an (incorrectly measured)
performance improvement !

If you didn't get the coordinates from SH, beware
of any profile you might obtain...

So, smooth and pray ;-)

Ah, the joys of sanding... No better way to bond with your ship.
Similar in many ways to good foreplay...

Sorry.
