The "upper" stage is a BT-20, and the booster motor is contained within a larger BT-60 tube, but falls freely.

I suppose I could actually build a booster section that has fins, and held within the BT-60, if CHAD staging is not allowed.

Here is a picture of the first page of the old plan, on JimZ Plans. This would make a great upscale, too, for 24mm or 29mm BP motors.
