Hi hammax, thanks for your input. I like the "eggy"-design. This will give some extra-space on top for putting the helmet in. Still I would like to integrate the straps into the design.
The harness is another topic. But you are right, adding some inflatable tail will decrease the drag [1]. In our case drag is not very important. It's more about lightness [2]. But the backpack is only for carrying the glider...
