Default UMX RADIAN w/ "BIRD of TIME" WING

So it seems i may need a Radian intervention.
I have a UMX Radian ( my 2nd one ) and an old and recently refitted Radian Pro and a new Night Radian which i got for Fathers Day.
I've been watching old videos of gliders and came upon a discontinued 3-meter ( 118" wing-span ) one by GREAT PLANES. I really liked the unusual wing plan and wondered how it might work with one of my Radian's.
So i decided to try it first on my UMX Radian.
The UMX radian is a scaled down version of the Two Meter Radian with a 29" wingspan. So in scale to the UMX Radian a meter is half the wing-span so 14.5".
Therefore three meters is 3 x 14.5" which equals 43.5".
I scaled the "Bird of Time" plan in my CAD program and plotted a half span wing about 22" long, added a 24" #3 CR bent the wing ends up per the BOT plans and stuck it on my UMX Radian.
Waited for the Windiana winds to die down and got a few trial flights at twilight.
It balances and flies really well and of course with a greater glide. I'll do a video when I can get to the field.

It looks like it flies very nice. My knowledge of gliders is very limited, having only flown one once and then with much help. The motor glider would probably be the way for me to go.

Was this wing a foam wing or a balsa build with covering. It looks like the leading edge was covered with reinforcing tape for strength. What an interesting combination for the radian. Thanks for posting.jb
