Does it significantly harm performance to put a thin screen (such as the one on windows to keep bugs out) over the fans? I still wouldn't feel safe with it hovering above me, they look like they could still cut off a finger fairly easily. Also falling into a fan in the full-scale version would be... bad. I really like that you're offering a drone rather than the full product (which often times doesn't get completed). Do you have anything written about the overlapping fans? I've never seen that design and am really curious about it's pros and cons. Great product if you can get the hoverbike done! Good luck!
