Over the weekend I launched my Madcow Avalanche with a Cessaroni J240-16 drilled to a 14 second delay. After reviewing the altimeter data, the actual ejection occurred at 23 seconds and resulted in a shredded parachute. Fortunately, this is one tough rocket and there was enough drag provided by the shredded chute (final descent rate was 32 fps) so that there was no permanent damage. Any thoughts on why the delay was so far out of bed ? I know there is a tolerance band around the delay timing, but this seems to be way outside that. Only thing I can think of is that delay grain did not light initially and miraculously did so on the plummet back to earth ?
