Good question. I don't see it on the Estes website or catalog anymore and looks out of stock on a few vendor websites. The rocket stopped flying in a straight line for me (don't know why) so it's retired. I did try to fly it at night on an E20 with a string of lights. That was cool.
I called the light rail folks and they never got back to me. It was just a $30 Estes altimeter so no great loss. The Flightsketch altimeters are out of stock so it's a bigger loss when I lose them.
