The Raven altimeter uses a 110mAhr battery and fires Q2G2 matches reliably. They're going to draw less than 2 amps at 4 volts. I flew my red Formula 54 on it, burrito style, on Saturday. I had a BigRedBee beacon in it and used my homemade yagi to DF it about two miles away. Those winds aloft were vicious. Josh flew his extended Formula 75 with one and with a BigRedBeeGPS. He has a Yeasu VX-8GR with built in GPS and APRS packet decoding and walked straight to it. Having a handi-talkie to call for help isn't a bad idea when you're walking around out in the desert. Ed, What is burrito style?
