Last update: 11/8 2010 First beta version of a system to stop the engine at will. This cut-off is activated by pulling the up line. When the bellcrank turn out of its normal position it will trick the spring and pinch off the fuel line. The trigger point can be set by the screw at the end of the kevlar line. The mechanic can reopen the system just by pulling the fuel line. Total weight of the system: 3 grams Price (only materials): Probably less than 1 euro
First demonstrated at the competition in Bitterfeld 2010
