Jim,

These pictures were all taken during the first two weeks of August. 
(2003, 
2005 or 2006)

Yes it gets cold if you fly in the winter; however, personally I don't fly

between October and March.  The large canopy does provide quite a bit of 
solar heating which is enough for summer flying.  In the fall and spring I

dress like I would if I was going skiing. Heavy boots and socks. 
(sometimes 
I even ware electric warmed socks) ****rt, sweater, down coat, gloves, ski 
cap, etc.  Canopy frosting is a problem if the vents are closed, etc.  So 
far my 12 amp hr battery has not failed even when the cockpit was
sub-zero. 
To date I have not had a temperature related instrument/radio problem. 
Oxygen is our main concern.  Remember, the glider altitude record is a 
little over 50,000 MSL.

I am sure this discussion has diverged far from the ultra-lite/homebuilt 
charter.  However, I will be happy to answer further questions via email.
