Estes Mean Machine #1295 plywood fins and centering rings upgrade for 29mm.

This is a plywood centering ring and fin set to upgrade your Estes Mean Machine to a 29mm motor mount. This upgrade will allow you to take your Mean Machine up a notch and use bigger, badder motors for spectacular performance.

This set includes 4 fins with through-the-wall tabs and two rings. You will need to cut your own tube slots and provide a new motor tube (as well as the Mean Machine kit).

This is not a complete rocket kit, just an upgrade.

Thanks for looking.
