Just a point about projectiles without gyroscopic/drag stabilisation, they start to tumble almost immediately after leaving the muzzle. Not a groundbreaking revelation, I'll grant you, but seeing it in slow motion does hammer the point home

I think you've posted it before... anyway it's worth seeing again
I've downloaded rocksim again.. not that I am interested in rocketery but I am curious if it's stability and cd predictions are right

I don't think I had posted this particular one, I've certainly wanted to refer to it in the past and hadn't found it.

Here are some other useful calculators for CP location of rockets/projectiles and other model rocket calculations.
thx, rocksim can use barrowman stability equations
I am really interested if it's cd predictions are accurate... it's not that hard to design a drag stabilised rocket with a cd value of 0.2 or less so that could be used to design long range projectiles for spudguns
