Rear window
Did I read on here that the after market rear window is no longer available?
As I recall it was formed and tinted, and some builders used it instead of Van's?

Yes, the maker discontinued making them, I think getting them delivered was a big problem, since they were formed with the curvature instead of the flat original. There was also a lot of discussion that the original window was structural, and the tinted one made of different material might be a bad thing. I have both, have not decided which to install yet. The original does not like fuel spilled on it, the replacement does not mind fuel.

Bad thing
Don,
What was the "bad thing" about the material of the curved tinted rear window? I have one and I recall some back and forth about plexiglass and lexan but I don't recall what people were worried about.

The concern seemed to center on strength of the replacement window material vs the original. There were those that thought we might be weakening the fuselage structure by this "untested" window, as I recall even Vans cautioned about it. I am no engineer, but if the rear window holds the plane together we are all in a heap of trouble, and if I recall correctly, my tinted replacement is thicker than the original. There are always those that want to see extensive testing before trying something.

rear window
Has there been much cracking around the screws that go into the roll bar. It seems to me that it doesn't take much to crack the window there.
Has anyone else had this problem?

Thanks Don, I do recall the structural questioning.
I haven't read about any cracking but there may be some out there.

The polycarbonate rear window that comes with the kit is the same type of plastic used for school windows and for bullet proof glass. It can be hit with bricks or baseball bats without breaking.
Acrylic glass breaks much more easily.

Makes me wonder how long it will be until vandals realize all they need is a gasoline container to vandalize a window they cannot break.
I also wonder when gasoline crazes it, does it effect its strength appreciably?

I think y'all might be referring to this thread from earlier this year about the differences between the windows...

Something may have changed. I very carefully made a rubber mat shield for when fueling, to avoid spillage touching the window. Then the VERY FIRST TIME I fueled the plane - from the flo-fast system using one hand with the crank - the hose popped out and made a big spill behind the mat and on the window!! darn!! But I quickly wiped it off with a rag as thoroughly as I could and there was no effect at all on the window. Now I jam in a no-lint rag with the plastic tube in the fueling port.
