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
