  • Flying wing

    I'm designing a BOT style flying wing. NO vertical stabs. If she flies as well as she looks... what a beauty! Doc

    The easiest way to avoid needing veritcal stab is to provide ample sweep-back. This acts somewhat like dihedral and vertical stabilizer.

    Then you'll want some form of controlled drag at the wingtips for yaw control.
    FF gliders and rubber power since 1966, CL 1970-1990, RC since 1975.

    current planes from 1/2 oz to 22 lbs

      I'm using sweep as well as dihedral just like the Horton gliders. An airfoil with a slight upward turned trailing edge (reflex) and elevons on the outer part of the wing only, are important for stability. Also washout can be difficult (if not impossible) on a folded foamboard wing, so extra reflex on the outer 3" of the elevons will help reduce tip stall tendencies and take the place of washout. I hope all this research pays off! Doc

        That's why I'm waiting til I get a 3d printer to continue my design. Gonna print the ribs out

          Let us know how that works out. I just finished my BOT flying wing airframe. (About $4 in materials) Now for the expensive part, electrics. It's 2 meters. If this flies I'm going to build a 3 meter wing, either BOT style or HO IV. Doc

            Nice I think it should do well. Just setting the battery always was the PITA part. To get that critical cg point exact. Uuuugh.
