Thanks for your reply. I have just a few more questions (right now anyway LOL
On the yellow vectorposter do you have carbon tubes along the sides or just at the front and rear?
It looks like the string in the front helps keep the power unit in place and creates the bow/curve that is needed. Is the string in the rear used to prevent twisting?
Are the 2 curved rods starting at the front of the power unit and running to the rear edge of the kite, used to support the power unit also? I would guess those are 3 mm also like the rear rods
This is really interesting and seems like something I can build. I will have to order those kite connectors
