Introducing the The Flip DT System for 12” to 16” Wingspan Gliders.
Catching a really good thermal for a glider in most cases is a good thing. But it could easily turn out to be a bittersweet experience—something that glider owners know too well—the dreaded O.O.S. Syndrome otherwise known as “Out Of Sight.”

“This D.T. system is about as simple as it gets . . . .when the lead ball falls away from the slot in the D.T. arm, it falls down and aft causing the center of gravity of the glider to shift aft about 0.75 inches, which causes the glider to suddenly stop circling in the thermal and immediately whip stall. To date, I’ve had at least a dozen successful D.T.s with this system in light thermal conditions.” — David Higgins 9/24/2020
