Kfm4 spec inspired wing

This is a wing that meets fpvwra specs except for the airfoil. I used a kfm4 2 layers of dtfb thick. The step is at 50% of the chord not including the control surfaces. In my experience keeping a thick step closer to the leading edge makes a very smooth flying wing.
For the video I just taped a gopro session on top.
Sharing because this is a super easy build that flies exceptional
