Good guess Gunny.
This poor build started over on RCScaleBuilder way, way, way back in 2012. Like many projects, I got distracted and this thing was mothballed, but recently pulled out again. Since it’s Summer now and sailing, biking, flying, and just being outdoors season, this wont be ready to fly any time soon. I recently resurrected it over on RCG, but the scale sailplane section over there doesn't seem to be getting any high quality traffic - well at least nobody looking at this one any longer. So now I’m hoping the final resting place is the home of scale sailplanes! Back to the future we go.....
After seeing the following video on YouTube (in 2012) and finding out what the little primary glider was called, I knew I had to build it. As you can see, the Hol's der Teufel is a closed cockpit variation of the good old German primary glider. It's been modeled before, but so have a lot of planes. I can only hope that mine comes in good enough.

Luckily, I also found a friend on the net who I am indebted to. He was able to supply me with all of the documentation I need to get this build going including a CD full of detailed pics from his own 40% Primary glider build which is now hanging in the Southwest Soaring Museum. I could not have asked for more or better reference material. Thank you Jim.
Well, that's about it for now. I will start catching everyone up from here.

And here we are now. My big progress this week has been getting the ribs glued to the spars - which sounds easier than it is with something like this. The diagonals aren’t even glued in yet and this wing is already very stiff. I had to add small spacers under the rear spar openings to fill the gaps (similar to the fulls scale), but everything is snug and tight.

Thanks Steve
Come on Michael, you know my builds tend to be on 10 year timeframes. ðŸ˜Comment

Ok, this isn’t all that exciting but also one of those things that I’ve been thinking about for a while. The leading edge of this wing is wrapped in ply, but it still has a small stringer that goes along the ribs behind the ply. So I made a pattern out of flashing aluminum that fit the spar and each rib nose with a small slot cut that matched the stringer width and depth. Then I marked it with a pen. When all were marked I made sure they lined up and started cutting with the dremel tool - very carefully. Lucky me, they all lines up very nicely and now I have a a nice straight basswood leading edge. By the way, that’s the framed up port side wing so now both wings are framed and glued.

Found this picture on a Facebook vintage glider group. Bungee launching the Hol’s off of a beach in Croatia riding ridge lift!

I managed to get most of the trailing edge on both wings installed by slotting each rib to accept a 1/16" ply strip which is then capped by a 1/8" square basswood trailing edge. It will need some slight shaping, but it turned out nice and straight and very stiff. And exactly like the instruction manual from 1935 says how to build it.
One of my deviations from stock was with the root rips. These will be capped with a ply strip and "out of sight", so I beefed them up a little and made each one out of 1/8" bass. They really don't take any kind of load like a typical root rib because of the wing attachment configuration, so I thought I'd try something simpler than build 4 more ribs from all of the little fiddly bits.

Yep, all I need to do is translate 70 pages of 1930’s German (which Google doesn't do all that well). After all, this was just a kit glider intended for lots of glider clubs learning to glide down Alpine hills!Comment
