Estes Mk-109 Stingray Build Part 3 Engine Mount

With the centering rings glued and dried, the engine hook is set into the forward notch.
There is just enough room behind the forward tab for the hook front bend to slide in.




 This is the notched engine mount section wet over the engine hook.
It almost snaps down in place over the blue tube.

Down the middle you can see the square recesses for the TTW launch lugs.

Here's piece two of the engine mount section being dry fitted.
I'd recommend dry fitting so you can see where the plastic glue will go.

There is three small notches in the lower ring that fit inside ridges on the engine mount sections.



Rubber bands were wrapped to apply a little pressure while the plastic glue dried.
The long TTW fins slots would dry raised away from the tube without the rubber bands holding them down.

The finished mount reminds me of the complex "wood girder" style mount used in the Q Modeling kits.
