Since flying my 60" canard slope soarer from 2010, I'm still looking for improvements. There are two obvious ways to improve the performance of a canard sailplane: 1) Make a bigger wing with higher aspect ratio, and 2) Use less canard area relative to the main wing so there is less interference. Along these lines I propose a new prototype slope soarer as shown in the attached images. The new design has a revised planform for the main wing which I expect will offer lower drag in the turns. The winglets on the canard have disappeared because they are only beneficial at the low end of the speed range, ie. not the main priority here.

Main wing:
span = 77"
area = 535 sq"
Root chord = 7.87"
Tip chord = 5.5"

Canard wing:
span = 19.7"
area = 72 sq"
root chord = 4.14"
Tip chord = 2.95"
