Can anyone create a step-by-step for this fix? Our launch day is very near and we can't afford to lose our data. While we are rocket builders and can understand most of what was written, we have no idea how to manually fix the problem. Dennis Oubre Robotics Rocketry Instructor AJ Moore

Casey Barker ca...@barkerzone.com writes: Hey Winton, this was also my first question to the altusmetrum list, about 2 years ago. :) Don't curve it around or dangle it outside. Just drill a hole in the bulkhead and run it up next to the chute, then use some RTV or glue to seal the bulkhead
