The Renner is a lot of fun! It is easily tuned by bending or twisting the wing tips. The Renner can also be modified to make a shorter range Fast Catch or Endurance boomerang. You can find ideas for modification under the "Renner- Bumerang" facebook page. Linked here: https://www.facebook.com/groups/912245250473004
(ALWAYS use a mask if you cut or sand this boomerang as the dust from the glass fibers is hazardous)
