Stabilizer and Elevator Installation

 

 

With the plane coming out of paint and the parts fully cured, it was time to start the final assembly of the tail starting with the horizontal stabilizer.

I also needed to remove all of the tape from the trim tab wire harness

You need at least one washer wrench, two are helpful to access the center hinge point due to limited space.

You will also need a magnetic extension to retrieve the numerous washers, lock nuts, and bolts dropped inside the elevator.


Installing the bolt for the center hinge point first is highly recommended before install the outer four bolts.

The bolt holes are not perfectly aligned and you have more room to work with the outer bolts than you do with the middle one.

Propeller Installation

It was finally time to install the propeller on the engine, this has been a long time coming.       The blades are unpacked one a time and i...
