Hooked up an LED to my Stratologger altimeter. Loose fit into the AV bay with rough undercoat/filler finish sanded back. Another LED and key switch will go in so I've got visual indication that Altimeter and Timer are armed. Rocket is a Performance Rocketry Nike Smoke - G12 airframe. First flight is planned for later this year. If I pass my L2 exam it will go up on a K270.
