"Mod C" Slow Flying UMX Radian

Here's an interesting mod by Rick Rademacher.  It makes the UMX Radian fly almost like a Vapor.  I'm going to try it!

Main Wing

  • obtain three Horizon Hobby Citabria wings (part PKZ3120).  Got mine here.
  • overlap two wings by 3.5 inches.
  • tape the wings together with a strip of tape on each side.
  • insert the wings into the fuse.
  • don't tape the wings to the fuse; the friction will hold the wings in place.
Top Wing
  • cut the third wing in half longitudinally.
  • mount it upside down on the other wings, leading edge forward.
  • lightly tape each side to the other wings
Krueger Flaps
  • use post-it tabs to make krueger flaps on the leading edge.
  • bend tabs to desired direction and shape.
  • vary tabs to match your desired style of flight.

Blogger can't find it, but the howto video is here:
