Summary

Tinkered from another single winged glider, I decided to make it a Bi Glider.
Added copy of original wings. Added 3 support struts for upper wing and printed.
Assembled all parts of main glider and finally mounted top wing 5 mm forward of lower wing on supports with super glue.
After initial test flit I added a small eye hook to move cg forward a little and added about 1% of up elevator on the rear using pliers to crease rear edges up to create a little up lift.
