It might leave you scratching your head why, if the the thing is grounded anyway? It's a simple, safe practice thing to do. Which if you follow religiously will leave you with radios that are crystal clear, and an intercom with no noise, etc. The best way to avoid, electrical/avionics trouble in a plane, is simply pretend the entire airframe is made of plastic, and treat every electrical device accordingly.

Grounding the lights and fuel senders in the wings to the airframe shouldn't cause any issues.

Also these articles address some of the more common engine issues and some of the ways in which we address them. This section is called Tech Talk and is where we will post all of our Products Testing Data. The articles are written by "Uncle Mike" because he is a far better writer than I am and his engine building experience goes far back to the days of Flat head engines and probably back to the days of wooden spokes though he won't admit it. Smile The First Forged 4340 crankshaft sample is now in an engine case with a cam shaft and will be running before too long. This engine will be equipped with our entirely NEW rotating assembly as well as the rest of our newest products. The first set of all aluminum Nikasil Cylinders will be installed and tested on this engine as well. We will have this engine at the upcoming Corvair College #13 being held In Livermore, CA. For further details of the Corvair College #13 event see www.flycorvair.com or www.flaglvk.com Thank you, -------- Brady McCormick Poulsbo, WA www.magnificentmachine.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=219111#219111 ________________________________ Message 4 _____________________________________ Time: 07:32:14 PM PST US Subject: Zenith601-List: Project in EAA Newsletter From: "PatrickW" Short article and pictures of my XL project in local EAA newsletter. http://www.eaa25.org/wp-content/uploads/2008/12/eaa25812.pdf - Pat -------- Patrick 601XL/Corvair N63PZ (reserved) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=219154#219154 ________________________________ Message 5 _____________________________________ Time: 07:50:52 PM PST US Subject: Zenith601-List: Simple rivet test/unzip From: "n85ae" This evening ... I took two pieces of .025 500mm long, riveted them with A4's at 40mm pitch. clamped the end of one in a vice, and grabbed the other piece with a pair of vice grips. One sharp tug unzipped the entire strip with very little effort .... Every single rivet head popped right off like butter. Riveted with the zenith hand riveter and zenith concave head. Food for thought.

They were my response to the unzipping of 601 ailerons in light of an examination of in-flight video by myself, my IA and my test pilot. The inboard one looks like a triangle, the next outboard, like a house. Zenith has incorporated similar ones on the 650, I am told they are internal and thinner. I know some builders have ordered them and installed them on their 601s. Zenith has their own reasons for the design change.

Do they apply equally to hingeless or hinge type ailerons? I still can't quite imagine exactly what these gussets do or where they go. Which rivets on the aileron can unzip? The Hinge area? On the ribs?

CH knows what he is doing. If anyone has the new plans, maybe they could describe the 650 versions.
