The original X-24 did just eject the motor. I made a few changes to make the model more "NAR Friendly", and field owner friendly. No one wants to get bonked in the head with an expended motor casing, and field owners frown on finding little paper tubes left behind by "those rocket people".

It looks like a 3.75" piece of BT-20 will work for the motor tube if you just want to go with the original plans. The things are REALLY stable, so having the motor a touch aft will not cause much of an issue.

Be sure to put some "dag barf" or recovery wadding in the top of the motor - helps prevent burns from the ejection charge.
