I thought this was a cool looking design and it seems to have some Estes history behind it so I built one up. I have three flights on mine and they all have three things in common - all flights were less than straight and I had ejection failures every time. The nose cone has blown off and away every time. On the last flight, it was secured with a parachute (full sized, certified skydiving rig) reserve closing loop and while that stayed in place, the two piece nosecone blew apart. Perhaps the body tube volume is so small that the ejection charge it just too strong or, I'm doing something wrong. Regardless, I quickly decided to scale it up.

Here are some pics of the original and it's big brother, which flies much better!
