Estes Little Joe 1, #7255, Build Part 7, Engine Mount

The engine mount is pretty standard except for the big rings.

On the right is the lower ring. The four nozzles holes are cut. The laser cut lines are the glue positions for the plastic pieces. Notice the off-set notches for the tabs in the motor housings.

The lower ring is glued 1/4" from the bottom of the motor mount tube.

The upper ring is two layers. The smaller ring with the cutouts faces up.

On the left is the finished engine mount.
On the right is the top showing the laminated two rings. The "spoke" holes keep the weight down.

Note that the interior 2" diameter tube fits over the lip of the smaller, spoked ring. Keep this in mind as you don't want glue around the edge (that could affect the tube fit) of the upper ring.


  1. Hi Chris!:

    What is the material that is holding the engine hook on? I think I saw it in the picture of all the parts in the kit. Is it like tape?

    1. Hi JHall,
      The retaining ring is a clear Mylar ring used in many kits.
