Estes Lynx, Kit #7233, Build Part 7, Seam Fill, Primer and Kevlar

The body tube seams were filled with thinned CWF.
Even the exposed seam on the rear of the engine mount got filled.

Fill the BT-5 intake tube seams before cutting.

Everything got a shot of Filler / Primer and light sanding with 400 grit.
The small vane pieces were stuck back on the tape after sanding. These would be easy to lose.

The engine mount got a length of Kevlar tied and glued beneath the upper centering ring.
The outside of the upper centering ring was notched for the Kevlar. This prevents the main air frame body tube from bulging out.
