ABSTRACT:
A reusable, semi-flexible molded model rocket engine igniter holder is used to hold an electrically activated igniter in intimate contact with the exposed surface of the model rocket engine propellant until the rocket engine propellant is ignited by passing electrical current through the igniter. The igniter holder, which is inserted in the throat cavity of the rocket engine, is preferably molded with a series of ribs around its periphery which impart a holding force keeping the electrical igniter in place in the engine throat.
