John,
Wayne Voyles and Larry Killingsworth jointly developed the Slasher and Ripper. Wayne is the Production Manager for Lanier RC and did all the part programming for both planes.

They are foam wings, HDPE fuselage, and coroplast tail feathers. There is an abundance of laser cut wood parts to back the control horns. The construction manual is very good time and the build time is minimal.

The only ones I have seen fly have been the prototypes.
