Hello,

This crossed my mind:

I have actually build CO8 (15 years ago), but i have made it too stiff and consequently too heavy

What class of thermal duration are you looking to compete in?

I've flow the Klingberg 100 and actually liked it in the AMA std class (100 inch).

There is now a RES Dart (F3-RES). This is a low key 2 meter class. I have a kit of this and it is very well made.

Now flying wings have a major short coming when it comes to contest work. That is that don't, or haven't yet, climb well on launch (winch or high start. Now with altitude limited motor runs this might not be such a problem for electric powered gliders.

Let us know what plans you come up with for a contest flying wing.

How can an aircraft structure be too stiff? I often use a lot of carbon fiber trying to get stiffer and stiffer structures!

All the best,
Konrad

Cut it twice and it's still too short!
