Estes Vesta Intruder #7312 Build, Part 4, Engine Vanes

The small hold down tics can be sanded off using some 400 grit wrapped around a used engine casing.

A dry fit showed the slots might need some widening or removal of the tics.

The fit of the rear centering ring was a bit tight around the BT-50 engine mount tube. 

Some 400 grit was wrapped around a D engine casing and the hole widened a bit.

I like to seal the exposed edges of the vanes with some white glue. This gives them a rounded edge and a smoother final look without the spray paint soaking in.

Note I am only making a glue bead on the outside exposed edges, not on the root edges.

On the right a bead of glue has been applied. Smooth out the sides evenly with a finger but try to keep a raised round bead of glue. Let dry.

Run a fingertip over the dried edge and you could feel some rough areas and high spots.

Lightly sand the glue bead with some 400 grit.
