Centuri Screaming Eagle Build, Part 4, Engine Mount

The way the plastic fin can locks onto the tube is well engineered.

The black coupler is glued into the top of the engine mount tube already in the fin can.
The bottom of the coupler rests against the top bend of the engine hook making it the engine block.


Here's the entire dry-fitted mount removed from the fin can.
From the bottom up:
The engine mount tube, the black coupler glues in above that.
A thick white adapter glues down and over the end of the black coupler.
The white coupler glues into the ST-8 main air frame tube.
The card engine mount tube is locked into the plastic  fin can without using any plastic glue or epoxy.



Above inset: Without the fin can in place you can see the stepped body tubes.

As mentioned in an earlier post, this model followed the design of the Centuri Stellar Spartan model.
From the Semroc instructions the Spartan tubes are stepped.
