Nice project. Back in the days when I was flying R/C all the time, I built an R/C plane down audio circuit that was very small and made with very little parts count. It was great to range check your plane and then if you didn't make the field, you could walk right up to in as the beeper was going off. And it took so little current that it would run for hours on end. So anything to help you locate your R/C plane is a good thing. Thumbs Up!
