I am getting ready to replace the panel in my Ventus B. Are there any
standard materials (especially the core) and recommended glass and
core thickness used to layup a new one?

This is a fixed panel, does not pop up when the canopy is opened.

I was thinking of using a 1/16" to 1/8" core of DIVINYCELL. So far
the thinest I can find is 1/8", is this too thick and will it handle
the compression of mounting screws through it?

There is a company: Aerospace Composite Products, that has various
types of pre-make composite panels. All are carbon or glass with
various "fillers" of foam, glass, and something they call Corelite
Other panels of thicknesses over .5 inch are done with foam and balsa.

I would check with them regarding using one of their panels to make
the blank.

I used many of their products in the past and they're always top of
the line.

Make sure you have some kind of rounded flange around your legs,
lest the panel turn into a knife in an accident. You'll note all new
gliders have this feature. Make a mold with a thick piece of wood,
rounding the corners, and lay up a non-sandwich panel for best
results. Its easy and much safer than a simple panel (especially
a metal panel).

Hope this helps,
