The guy was a guide at the airport and told me, he newer flew trike. We returned after sunset, but a short test flight we did. He was happy and maybe we will have a new student.
It was thermal day with dusty cross wind. Then Branko, Adriana, my wife Jana and me went to restaurant somthing to eat and one beer. We flew with Branko about one hour later.
A British pilot came to do a test flight on the ES-trike. This is a very light trike and also available with electric motor with various sized battery packs.
I wondered how much extra drag my round down tubes create versus an airfoil type tube. I grabbed this link from another site (name not mentioned), and I was very surprised to see this professor's test results. Really interesting!
