Flite Test Flat Flyer P-51 tail wheel

I plan on landing on concrete and didn't want to destroy the foam board so I made this. I used an M2 bolt for the axle fit loose and pressed it into place enough to make an indention in the foam so I knew where to make a small slit for the axle to slide into the foam then a little hot glue. You could also use it without wheels as a slider.
