The Alpha: What can I say? Ask anybody, they probably have one or two.  This was built from the original 1974 kit, bundled with the starter kit / launcher for about $14 and some change.  I ordered it when I was 13 yrs. directly from Estes mail order, sending bills and change in an envelope without telling my parents because I was too afraid they would say I couldn't get it.  It's always easier to get forgiveness than permission!  It was a rugged, good flyer. It has since been moth-balled, the shock cord is rotted. I restored it to flying contidion one day when I was bored. It received a new Kevlar shock cord mount and a better plastic parachute with longer shroud lines.  I also added a small payload section to the top, making this rocket 2-1/4" taller and 5 grams (0.176 oz) heavier.  I flew it with an A8 on a windy day, and I was suprised how straight it flew, reaching 210 feet apogee and going up to 71 mph (104 ft/sec.).  Can't wait to try this on a B or C this weekend!
