I agree with unstable. I would slave it to the throttle for you to help flameouts at low throttle settings w/ no flaps (taxiing). With a little tinkering and a 3 way switch, you can have an off, on, and "throttle" setting. I actually made one of these a few years back to go in my GP ultimate so I didn't have to chew up the cowl. It worked great, but I scrapped it in favor of less weight. It can be done though either way though. Good luck.
