I was just made aware of an undisclosed change in the wing KAI: Outboard stringers were added to the skins somewhere after 6.4 (which my kit, #512, came with, and which does not show them) and 6.6 (which does show them). This change is not in the list of revisions in 6.6. My kit came with the string...

Since this is the "tips & techniques" section, I'll add to this very old post with my procedure: While I use the circular and edge deburring tools that are commonly recommended, I find that they still leave a noticeable burr. I always go over the edges with a Scotch-Brite wheel, in par...

What would be the advantage of using this, are you afraid of corrosion?

I have a 915 cowl with the alternator bump I won't be needing, but it's in Sweden so probably not useful if you're in the US...

When the kit arrived had a small heart attack when flipping through the KAI and it talked about having to counter sink most of the holes on the Main Spar. Was delighted to see that was already accomplished when I pulled them from the container. Lucky you. I just started working on mine, which had n...

Yeah I guess you're right, it's just weird that they note all the various local Mogas standards, like "Ukraine" for 916, but not local avgas variants. Maybe Ukraine is a large market for 916-driven UAVs right now so they wanted to get that in, but I'd think they'd be familiar with the avga...

There's a typo in your link, it's missing the colon after https. Looking at the latest SI for fuel I see it saying "Min RON 98" for the 916 (the other engines have min RON 95 as you state in your post.) I was interested in whether avgas ASTM D910 91/96UL as available in Europe is acceptabl...

Supposedly, even dimple dies of the same diameter and angle are not interchangeable, because depending on the material they are intended for, the shape may be slightly different to allow for the "spring back" of the material to make it come out flat when the die is removed. I have no idea ...

The HW has a 6 litre header tank on the back if the firewall which supplies the main fuel pumps. The two feed pumps are located between the fuel selector and the header tank and their purpose is to keep the header tank full. Without a feed pump running, no fuel will be pumped into the header tank a...

I'm not familiar with the HW, what is the "feed pump"? Is this another pump that's different from the Rotax fuel pumps on the firewall? Because those are powered by the engine directly.
