Hi Freedomflier,
This is Max of BME Aircraft, just browse through and saw this thread talk about BME Yak. Thought I jump in and anwer your question and all others if any. The CF wing tube dia. of the main is 1 1/4", same as our Edge 540, 3' long, it's able to stand most harsh blender punishment.

BTW, YNC is right. We've been very careful about the weight now. This Yak will be 8lb or less out of the box.
