Last update: 9/3 2009 A German shut-off system Design by Johan Schwarz A "String-inside-the-Wing" system that is very easy to move form model to model. The lever inside the wing is detactable and the spring is adjustable.
The base part of the system is mounted on the engine barings. The lever can be hooked on and off the spring. Making it very easy to change models. The spring can be adjusted by use of three different mounting holes. The fule line parsing the shut-off and right through the model. First test flight at Munich, Germany, Marts 7. 2009. Lothat Hentzel, Johan Schwarz and Rudi Königshofer
