Price: $7.99 each


Motor Retainers for 18mm Motors (3 Pack, Estes). Two-part retainer - threaded part is glued to the outside of 18mm Motor Tube and the other piece screws onto it to hold the motor in place during the ejection charge. Fits our T-20 Tubes and 18mm Engine Mount Tube. Can be retro-fitted onto many models that are already built as long as the end of the engine tube is exposed far enough (about 1/2" or longer). For use with 18mm motors only. Comes with three sets per package.
