It appears that F2D will require shutoffs in the future. Henning Forbech has been working on a shutoff designed especially for the RTFs commonly used for F2D. He has a nice website illustrating his design. Unfortunately, his conclusion is that it's not adequate for competition use. In response, Gary James created a forum dedicated to shutoff design.

This particular page will try to document some of the ideas Howard Rush has been exploring, with my occasional help, for building an electronic shutoff. We have two ideas for sensing broken lines and two ideas for shutting off the engine, implying four combinations. Hopefully something will work!

In the beginning, we wonder how much energy is required to pinch off a piece of fuel line.
