FlisKits Tartar Build Part 7, Tail Shrouds

Set a glue line at the centering ring joint and slide the slightly flared shroud end down onto the glue.

The instructions say to glue the tail cone shroud onto the end of the coupler.
The shroud actually overlaps the coupler end. Lay the small glue line on the side of the coupler.
Press the tail cone over the edge. Remove all excess glue from the edge.

Check the fit of the engine mount and interior shroud.
Set the interior shroud above the larger tail cone.

Apply a thin glue line inside the end of the larger tail cone and press the interior cone even with the end of the larger, outside cone.

While the glue is still wet, roll the end of the Sharpie over the ends and "mold" the two edges together.

Roll over the outside then roll over the inside smoothing the ends until the glue sets up.

Turn the engine mount in the body tube end until you find one spot where the shroud best matches the tube end.
Mark the tube at the shroud joint to match it all up later.

If the shroud doesn't match well (if there is gaps) sand the tube at the high spots until you get the best fit all around.
