The original design was 7 degrees.  The main spar was changed at sn 813 to
accommodate the cast gear. If the dihedral was changed it would have been
then as the same spar seems to have been retained through the end of
production of the M10.

Tandy, 

I may be incorrect, even tho Wayne have agreed that 5
degrees is correct. The M-10 specs do show 5 degrees..

However, to be correct ,,,,, :)  

On Page 347 of "The Ercoupe, A Touch of Class", is a
write up about the 415C coupe modified to retractable
gear..... Here it states  " ...he added the speed kit
and decreased the dihedreal from the normal 7 degrees
to a mere 3 1/2 degrees.

So, Maybe 7 degrees is correct. Somewhere I have read
about the wing design, and mention of dihedreal, but I
do not find it ai any specification sheet.
