[Disclaimer: I know that adding an ejection charge to a stock motor like a D12-0 would not be allowed at a NAR launch. I would either fly this under TRA experimental rules or in a private launch and personally assume potential liability.]
I recently built an Estes Ventris and attached two boosters to it that were designed to fall off mid-flight. The mechanism for separation is similar to the Apogee Component's design, where the motor's ejection charge initiates the separation. Consequently, the boosters stay attached to the rocket during the delay portion of their engine's burn--i.e. when loaded with a D12-3, the boosters stay attached to the rocket for an unnecessary 3 seconds.
Can I make a motor with a shorter ejection charge? Has anyone tried adding an ejection charge to a D12-0 or adding a thin delay followed by an ejection charge to effectively create a D12-0.5?
