Since this is not a conventional rocket, figured I would ask this question here. Anyone know the CP measurement for the Estes Screaming Eagle?
I have built at least 3 of these rockets and up scaled one to 24mm motors, they are great rockets.
Use the amount of clay they give you and DON"T use an A motor it will not give it enough thrust to get going (even B's motors are iffy)
and in the swing test you tape the string to the center balance point with the biggest motor in it, add weight to the nose not the tail until in flies horizontal.

I flew the up scale once, she did very well, but couldn't find her in the crops at our field. :sad:
I want to shorten the tube and go dual cluster in the back. This obviously requires more nose weight but how much?
And yeah, I wasn't impressed with their response. Seems a lazy way to do business and her Cg/Cp relationship was incorrect. Then again, they don't calculate Cp so...
