"We finally had a clear day and an FAA waiver for our launch yesterday. We launched an L1115. We were aiming for 10,000ft and got roughly 9600ft. We are Unbelievably happy with your AIM XTRA gps unit. Soon after launch we lost visual of the rocket into the clouds and never regained site of it. During the flight we continuously received data from the unit and tracked it. Due to the high winds we found it in a corn field about a mile away. Everything worked without a flaw. Attached is the kml and csv file obtained from the unit after recovery. We never lost signal and found it within 10 feet of the gps coordinates on the unit. I absolutely love this AIM XTRA.
