Custom Nomad Build Part 3 Engine Mount Parts Prep

The first step of the instructions don't mention notching the centering rings for the engine hook.

You should cut a recess notch. Otherwise, the hook could press and deform the tube out of round. You don't want the tube to press against an inserted engine.

TIP: When cutting the notch, keep the cuts away from the inside centering ring seam. If cut too close, the ring might de-laminate or unroll. Sometimes there isn't enough glue holding the rolled paper together.

In the picture I've marked the notch and the seam. Just keep your cut notch away from the seam.


The rest of the engine mount is a normal assembly. I did add a length of 135 lb. Kevlar looped under the top bend of the engine hook.

Here I'm dry-fitting the mount into the body tube.





TIP: Always dry fit the mount before using any glue. More often than not, you'll have to sand down the centering rings for a slip fit.
