We had two TARC teams at our club launch yesterday. One was pretty good, but they only got 707 feet on their first test flight. No idea what the duration was, but it was probably pretty close. The second team had clearly done no prep work. Their rocket went about 50 feet in the air and was arcing over almost as soon as it left the rod. It landed in the small stream near the pad and about 5 seconds later the ejection charge went off.
