    Does anyone know how much black powder is used in the ejection charge of a D-16 Q-JET motor? Can the cap be removed and the charge size increased?

    I know the early Q-jet charges were 1/2 gram. They reduced that before producing C/D Q-jets.

    I have an old Estes foam shuttle rocket glider. The ejection charge on a c12-4 blew the nose off of the shuttle. Seems pretty stout already.

    I'm looking at the hex cap of a QJet, and it appears to be epoxied in. So I'll venture a guess and say it's not removeable. Also, modifying a commercial motor is not allowed under NAR rules. Don't know if that matters to you.
