Mark,
I've downloaded the revisions to the build manual and have noted the changes you mention.  The pictures on your site are helpful--thanks.  What thickness and type of foam did you use, and how many BIDs on each side?  I received 6"x24" x 1/4" 4.5lb foam with my kit, which I've already used.  I just bought some more along with my order for an additional set of alignment plates and strikers.

If holes are not drilled through the stiffener, how is the air ejected evenly across the canopy from the glareshield?  Is the glareshielf modified, or is the intent that the glareshield creates a close gap with the stiffener through which air is forced?

I've seen many references by Lancair builders that a prepreg is a sandwich of foam and symmetric layups of BID.  On page 1-23 of the manual prepreg is defined as a honeycomb panel.  Is this like the avionics shelf that came as an option (p/n 4943)?  I've always understood prepreg to be stiff tacky cloth--carbon fiber or fiberglass--pre impregnated with epoxy, that must be refrigerated until shortly before use and heated to cure...

 Thanks,
- Kyrilian

Lancair no longer recommends using the canopy as an airbox with the holes
drilled at the base of the windscreen for canopy defrost, instead they
suggest running a hose to an outlet in the glare shield.
