Yes, I saw it on http://www.vasamodel.cz/.
They also have the F5D Kyrill which reminds me of a Raketenwurm 2b with only 1.380mm wing span. Found 2 videos of the F5D Kyrill on youtube but there is no info on F5D Sporadic so far. Was wondering if someone had any insider info on who's disign it might be. Also, does anyone know how successfull the F5D Kyrill was in competitions?

Hello Vaclav,

Thank you very much for posting the pictures. The plane looks very elegant. I really like the shape and the geometry. In my opinion from appereance it is so far the most beautiful design on the market.

Question 1: For those who would like to have flaps, will you offer a version with flaps?

Question 2: The wing is very thin. It must be a real challange to make it rigid and light. Once you start building it, could you please inform us of the materials and the layers that you are using + the resulting weights?

Thank you very much.
Děkuji moc.

Ilya
