In recognition of the Oppenheimer movie coming out, I made a small "Little Boy" model rocket. Model is built around BT-55 & BT-20 body tubes and is designed to launch on a 13mm mini or 18mm engines. I will also try to make a BT-80/BT-55 scale version.
I opted to put 1oz in nose so that I could launch on a range of 18mm engines but I think it would be stable with 1/2oz for 13mm mini engines launches.
The boxtail is around 27% larger to help with stability (mainly me just rounding off numbers and letting it get a bit larger since it cannot hurt). For the BT-80 version I will try to keep the box tail closer to scale since I will have more length to work with (and parts should be proportionately lighter).
Test flights to come next...
This time period definitely represented a turning point in US and world history (not to mention dramatic advances in rocketry technology). I hope world leaders never forget the past or we may be doomed to repeat it.
