   Post on Wingtips Hoerner style in Avid Model IV

   By wypaul, posted 23 March

   I’m in the process of building some new wingtips for my Avid.  These are epoxy/glass.  I actually started building them a couple of years back and just now getting down to laying them up. The plugs are made from laminated pink building foam from Home Depot or the likes.  The shapes were cutout with a Hotwire knife. These will be built into wing tanks.  The nice part of the Hoerner tips is that they will increase the effective wingspan by over 30” without increasing the actual wingspan. What to expect according to available data is slower stall speed, greater climb, slightly higher top speed and greater range (time in the backcountry.  
   I can post photos as the project progresses if anyone has an interest.
