I am assembling a Citation Patriot -- and modifying it for 24mm engines instead of 18mm engines. When I was a 12-yr old kid, I flew this rocket with a friend named Roy who was a few years older than me, and got me into this hobby. This was the late 1970's, maybe 1976.... Anyhow Roy had this particular rocket, but I remember it being wider, like a BT-80 tube. I don't remember it being this skinny, but perhaps my memory has fogged over time. Was this kit always a BT-60 tube, or did Estes scale it down to make it cheaper? The old joke about things looking bigger when you're a kid can apply here perhaps.
