Hi! I crashed my plane do to insufficiently charged battery and decided to build low battery alarm. I looked around and there seem to be two kind of alarms: with LEDs and with buzzer (and some of them have both).
What kind do you preffer? I found very simple and cheap schematics http://www.ncws.com/rcrock/lowbat3.htm that uses buzzer. BTW, the plane is DLG with small battery.
