7.5x Estes Echo

[loopy]

About three years ago, I started work on my biggest rocket. It’s a 7.5x upscale of the Estes Echo, which I call Massive Reverb. Well, it’s finally done (other than paint), and has flown successfully!

The rocket is built with LOC tubes (other than the 75mm motor tube, which is PML), and a LOC nosecone. Fins have a layer of 10 ounce glass then a 4 ounce layer tip to tip. 5.5” diameter, around 7.5’ tall. Flew on a K456 dark matter motor to a bit over 2100’. Loved it!

Any truth to the rumor that you're bringing the big box of Crayons (with the sharpener) to the next build night at eRockets and doing a stained glass window motif?

I'll take any chance I can to slip a good pun in. We all know, "A good pun is its own reword."

Is that a euphemism? It sounds dirty.
