NewWay Angled Invader, Part 4, Filler Primer & Engine Mount

These are the square "dowels" that are glued on the outside tubes.

Here the pieces are sprayed with filler/primer.

Two of the smaller fins, there are four in total. These are glued as ribs over the open area on the wing.

Before with filler/primer sprayed on the left, 

On the right, sanded to surface leaving a bit of the filler/primer in the remaining balsa grain pores.

The engine mount has a slip over engine hook retainer band.

The Kevlar line is tied around the top of the tube.
 

Notice the square centering "rings" at the top and bottom of the tube.

A great feature of recent New Way kits is a heat shrink tube to protect the the Kevlar line from the ejection charge heat.

For all the "newbies" - Kevlar is flame resistant, not flameproof. It can deteriorate and fail after 10 (or so) flights.
