Static Air Tubes & Antenna Cable Install

As the build has taken a break until I can relocate, I've not completed some of the more recent posts - I'd better do that now.

Regarding the static air system, I decided I like the Cleaveland Aircraft Static Air kit much better for two reasons:

1) the static air port on the Cleaveland system looks much better than a cheap rivet. I've read many of the discussions on Vans Airforce relating to convex heads creating a localized low pressure potentially affecting the measured static air reading, but from what I can tell, that's mostly propaganda and those using the updated system have no issues with them; and

2) the tube connections look and feel much more heavy duty than small t-pieces provided in the Van kit. These larger black connectors make it much easier to disconnect/reconnect if required as well as providing a good seal.


This shows the Vans supplied static air t-piece compared to the above...



Here, I was simply measuring the length of tube required to create a nice smooth bend.


As the next photo shows, even after I heated the tube with a heat gun, I could only get the tube on half the distance I was aiming for. I'll need to try again at some point to get it on all the way.



Here is the UAT coax antenna cable ready for connection.....which probably won't happen for another 2-3 years I'm guessing.


In a previous life, I worked in the automotive industry and I small trick I picked up was the use of cloth tape to reduce cable chaffing and damage caused by vibration.
Therefore, at each zip tie I've wrapped the cable with a piece of cloth tape for that reason. I know - there's probably a better chance of vibration along the cable where the zip tie isn't. I'll just have to keep an eye on that.





The next few photos show the rudder cables running through the bulkhead grommets...



This is the cloth tape I used as vibration/chaffing protection for the cables.
It comes in various widths.
