Parts from the Estes Big Daddy kit surrounding the Aerotech Motor Mount kit.
The Estes parts on the left were added to our spare parts bin.
The parts on the right were used for this build (Body tube, nose cone, and fins).

So many options for our launch guide: heavy duty 1/4" launch lugs, surface-mount rail guides, or rail buttons?
Shock cord: Apogee bungee cord or Aerotech flat shock cord?

Centering-ring dilemma: Is the motor mount tube considered thick or thin wall?
Is the body tube thick or thin wall, or heavy duty cardboard?
By 3" tube do they mean inner or outer diameter?
There were so many options that we purchased a few hoping for as little sanding-to-fit as possible.

The Aerotech motor mount tube seemed to call for an Aerotech motor retainer.

Aerotech 1.9" 3-fin motor mount kit. We used the tube, baffle, screw eye,
and cooling mesh in this build and put the rest in our parts bin.

Bulkheads & Hardware.

Display stand (which would turn out to be undersized for this build) and chute-protector (it can't hurt,
might help if we can afford a Chute Release, and might be necessary if we drop the cooling mesh and baffle).

Pins & Swivels.

The far-too-big-for-this-application u-bolt.

Poster board for skinning the fins.

We are cringing over our failure to rotate all images to the same orientation,
but at least we managed to keep them in focus and avoid fingertips in the corners :)
