This must be done very carefully, as small misalignment of the Gear Leg Fairings will result in more drag and even worse if it’s done asymmetrically, it will result in a yaw.

The Gear Leg fairing itself consists of a piece of glass-fiber, with a piano hige riveted in the back. This way you can detach the Fairing by removing the hinge pin.

With just the piano hinge it can still move around the gear leg, so on the top there is also a hose clamp fastening the Fairing into a fixed position, relative to the Gear Leg.

We need to remove the Wheel Pants, so we can insert the piano hinge pin from the bottom up.

We probably made the piano hinge too tight, because it took some effort to get the hinge pin in. I wanted a tight fit, but maybe I’ve overdone it.

We used the Endoscope to check where the pin was going, so we could apply local pressure on the Fairing to align the piano hinge segments.
With some oil and pressure we succeeded in inserting the pin all the way to the top.

Now we can align the marks we made earlier during measurements, position the Fairing and fasten the hose clamp to fix the Fairing to the Gear Leg.

With the experience we gained on the right Gear Leg Fairing, the left one went much easier. We used the endoscope, some oil and voila, Fairing is in place.

Positioning it with the marks and clamping the Fairing to the Gear Leg.

Empennage Fairing http://ph-mnx.nl/2020/06/19/empennage-fairing/ http://ph-mnx.nl/2020/06/19/empennage-fairing/#respond Fri, 19 Jun 2020 21:00:53 +0000 http://ph-mnx.nl/?p=2569 I’m not a docile sheep wearing a Corona-scare face mask, but while sanding and filing fiberglas, I tend to wear a dust mask.

The Empennage Fairing is a tedious part of the build. It’s a more complex form and some builders don’t use the standard fairing in the kit, but construct one themselves.

I don’t have the epoxy/fiberglas skills to go that way, so I’m condemned to sand and drill and then fix stuff again, because I did too much sanding.

The whole Empannage Fairing took me two weeks to get it to the level that I was content with the result.

Good part is that now I do get a feeling for mixing epoxy and flox te fix stuff.

The Empennage is now completely finished, except for the paint job and final assembly once on the airfield.
