Estes BOSS Kit #7316, Build, Part 2, Engine Mount & Vane Prep

Building the engine mount is standard. 

Check the fit of the rear, split ring. The cut was a bit rough on mine so I cleaned up the inside cut on a sanding block.

The face of the rear ring will be visible on the finished model - it is even with the end of the BT-50 tube. Sand the exposed face of the ring smooth. For an even smoother painted surface, wipe some wood glue into the low face. Let dry then sand smooth.

In the picture I'm not gluing the mount into the BT-50 tube yet - 

Setting the lower ring in the BT-50 tube. The outside tube holds the cut ring closed around the BT-20 tube as the glue dries.

There are twelve small vanes that sit behind the upper BT-55 tube.

TIP: I have removed them from the laser cut sheet but left them side by side in pairs for easier sanding. They are pretty small.

Sand the outside edges while the two vanes are still together, shown on the right.

Now you can cut them in two and sand the remaining trailing edges.
