Estes Mini A Heli #007272, Build, Part 18, Hold Down Thread

The instructions show two small holes "drilled" on opposite sides of the body tube.

GOTCHA: The burn string and helicopter blade deploy is not explained in the instructions or on the website. I understood how burn-string models work before assembling the kit, I've been around a while. A first timer might be confused.



Don't just blindly drill two holes with the tip of a hobby knife. Measure and mark the hole locations directly opposite each other.
These marks are 6" up from the bottom of the body tube.





A new blade with a sharp tip was used to start the thread holes.

After a small hole was made, it was rounded and cleaned up using a smooth sharpened dowel.

The holes got some CA glue applied with a Q-tip. Light sanding followed.

A needle is used to run the thread through the holes.



Fold the blades down with the ends between two fin faces. Hold the blades down against the body while tying the thread.
Follow the instructions illustration to weave the thread around the blades.
Tie off the thread with the blades are held against the body tube, each blade set between two facing fins.
Set the three rubber bands into the hinge hooks.
