Makes sense. And the projected altitude?

We are building the rocket to fly it in.
We will probably change the geometry to a 100mm core instead of the 75mm
core used for this test.
That will give us 2,500 pounds of thrust for 12 seconds instead of 1,800
for 18 seconds.

Did the world largest rocket motor actually fly? Cause that's about 18
seconds of burn time, looked great!

We did similar but for a much larger motor and it worked fine: Worlds

Tell me what you think of this find: (see attached photos) It's a
stainless steel nozzle disguised as a Wilton's cake-decorating tip. Found
at my local craft store for 99 cents. It's .714" wide at the base, 1.24"
high from base to apex. 15 degree angle from center axis. Steel is .01
thick. Since it is so smooth, I plan on using it to mold nozzles instead of
turning a wooden mold on my lathe. But what do you think of the possibility
of using it in a small motor?
