Ok, well, I don't know what happened to the first post, but that seems to be entirely gone now. So I'll repost my question:
Why is the the ejection gas port on the Astron Sprite below the top of the engine hook? It seems like the motor case would block the port and prevent it from working, unless there's something I'm missing. Was the fit of the Series III engine into a BT30 tube loose enough that it allowed enough flow past? It seems like a neat design, but this is the case, without the original tube size or intended motors available the design would have to be modified to build now. I'd actually like to downscale it to a BT5 and use a mini engine, and the ring tail could be a BT60.
