I think (maybe hope is a better term) that Steven Richman had some aerodynamic reasons for the tip plate heights for his record LPP. At any rate it seems that most of us using similar models have adopted proportions similar to what he used. I don't know the exact dimensions on Steven's model. My LPP tip plates are 3" tall on the wing and 2" on the stab.

  Bill Gowen and All,

  When you build flat wings or stabs with no dihedral but with tip plates, how do you decide how tall to make the tip plates? Or how much area, or whatever way you choose to describe the size. I have Bill Gowen's record F1M plan, his Finny '09 SO plan, a Harlan Big Dipper SO plan, Bank's Leading Edge SO plan, and a few Mini-Stick plans. I did not find a LPP plan that showed tips, and I have some frameworks underway for Electric, Indoor Towline, and/or LPP.

  Someone has a method that is better than TLAR, or at least a more experienced TLAR than mine.

  Thanks to all,

  Fred Rash
