Examples

“"One of the most bittersweet joys in model⟳ aviation is an out of sight flight by a Free Flight model⟳. While we all strive for our models to fly⟳ as well as we can, it is possible to have⟳ a model⟳ fly⟳ too well. Well trimmed, and with a bit of luck, a model⟳ can be caught in a thermal and climb⟳ to beyond the limits of our vision. It is the purpose of a dethermalizer to effect a change⟳ in the geometry of a model⟳, such that it descends more rapidly, yet still safely. Getting the DT to activate after a target⟳ time is the job of a DT timer." ~ Thayer Syme. Reprinted with permission.”
