Mike Schipper wrote a very slick tool that allows you to edit the User-Definable pages on the Grand Rapids Technologies EIS 4000: http://www.my9a.com/eis/ Here's what Mike says: The purpose of this tool is to quickly and easily design...
Ouch. I'm not happy. My left elevator just fell off a workbench and landed on a can of kerosene, dinging the leading edge. I'm going to see if I can find a metal expert here in...
Got this info from here: http://www.acroname.com/robotics/parts/R67-UVTRON.html [caption id="attachment_16676" align="alignnone" width="320"] OLYMPUS DIGITAL CAMERA[/caption] This detector is amazing. Using the included sample circuit, you can detect a match lighting from 5 meters in a sunny room! Since the UV...
Do I need to do anything about a 2-3 Hz joystick oscillation that does not damp, caused by activating the aileron servo while the airplane is on the ground not in motion? Thanks, guys, -Bill Boyd From: Jerry...

While trying to get my strobes hooked up I discovered that there are at least two different types of "Molex" pins. I needed to replace some on one of the wires connecting the rear strobe,...
I bought the skybolt fastener kit for the cowling. It was kind of expensive (about 250 USD). I got only the firewall part - I plan to use hinges for the horizontal top to bottom...
From Robert Paisley - Here is a good source of NACA vents for the bottom of the cowl. Robert used the 4"x9"x1" (C42-017) model: http://www.chassisshop.com/pdf/fabrication.pdf ...
I asked Van's about balancing the elevators, and they recommended just putting the counterweights on, and not worrying about balancing it. A bit to heavy is apparently not a problem. Ideally, the elevators would be perfectly balanced. If the...
I've been trying to figure out the best place to install the fuel pumps and filters for several months. I had the following goals: Maximize head pressure on the pump inlet Minimize heat on the unpressurized sections...
My fuel pumps came with what look like brass nuts and a split lock washer. I've read that these split lock washers are not recommended in an aviation application. I would like to replace these...
Here are the tabs I had welded to the muffler. Also, the bracket that will attach these mufflers to the lord mounts in the fuselage. Here are my detailed engineering drawings. Here is the bracket mounted to...
I had been using a plunger type canopy stop, but I recently saw something cool on a few RV8s - a kind of cam shaped canopy stop. The advantage of the cam shaped canopy stop is...
I did see a few really cool things at Oshkosh 2005. It was my first trip there, and I have to say it was really good. Here is some stuff that I saw that I liked:...

Close up of one of the welds. This is the area I trimmed. Here is the swivel ball welded on. Update:If I were doing this again, I would not use this type of swivel ball. See...
The reason garlic is so toxic, the sulphone hydroxyl ion penetrates the blood-brain barrier, just like DMSO, and is a specific poison for higher-life forms and brain cells. We discovered this, much to our horror, when I (Bob...
Header tank leak Gregory Allmann This past weekend I had an experience that i felt I should pass on. I have an Eggenfellner Subaru engine in my Glastar. I installed a 6 gallon header tank behind the seats...
This is a continuation of the original article on Wheels and Brakes. I was not too comfortable with the short aluminium tubes that hooked up the brakes to the Grove gear. You can see photos of...
Information from Chris on the subaruaircraft yahoo list about balancing the MT Propeller. Where should the small weights be attached? To the spinner backplate, make sure that the bolt clears everything. Use AN3 bolts, 1” washers and...

The canopy skirt is supposed to be one of the more difficult parts of the project. Now that the canopy is glued on, it's time to bite the bullet and start on the skirt. One...

Update 20210918: I didn't install the Eggenfellner Subaru engine, so any post that references that can be ignored or used as a cautionary tale about how to avoid wasting many years and $50k. The first time...
The exhaust system as delivered didn't fit right. The pipes came down too low, and were too wide. I've cut them, and now I need to get them welded. Here are all the parts that will get...
