Georgia,

To solve the sun problem to some extent, I have installed a sunshade from
Skyport Ercoupe Services.  And I have put tinted plexiglass rear windows
in my coupe.  These things helped a lot.  Also the sunshade makes the top
of the canopy smooth since it is actually a third window.     The
original two windows rise to meet it at the top on each side.  Someone
pointed out that the top of the canopy where the two side windows meet is
an area of high drag, that the Alon type slide back canopies have less
drag since they are smooth on top.  After all, the canopy itself is
somewhat airfoil shaped and the aerodynamically unclean area of the two
sliding windows meeting at the top may create more drag and less
potential lift at that area.  So I concluded that my sunshade is
"cleaner" on top than without it as far as drag is concerned.  Who knows?
 But the sunshade looks nice and makes the cockpit more pleasant by
cutting down on greenhouse radiation inside.  You know, them little gamma
rays bouncing around excitedly inside yo plexiglass making temperatures
unpleasantly high in the cockpit.    Not to mention another hazard, basal
cell carcinoma, or squamous cell carcinoma.   The sunshade is aluminum
framed like the windows, fits into the tracks, slides from side to side,
and has very dark plexiglass.
