If you want to change the airfoil so that you reduce drag a little
to let you go faster,  you will also reduce low speed lift resulting
in higher stall, takeoff, and landing speeds.  That just sounds foolish for an unpowered glider.

Hi John and Member 67 it’s a pleasure to hear your 
response,
 
It makes sense that the speed limitation of the 
aircraft will preclude any aerobatic activity. I am still looking forward to 
learning the art of building a superlight wooden aircraft, especially one with 
excellent lift and maneuverability. I am not looking to put an engine on my 
glider, but rather make it light. The lighter it is the closer we can be to the 
birds. One modification that comes to mind would be a change in airfoil shape 
that could increase its speed window a touch, though I think I need to 
experience the feel of takeoff speeds before I go and adjust it.
 
Is there anyone in CA, or in the western 
United States, that is active on this site? I will need to find a good 
source for Member 60 soon.
