ULF 1 German Wood Sailplane

ULF 1 German Wood Sailplane
In this episode we travel out to Mooresville NC to visit with Holliday Obrecht where he, with the assistance of his EAA Chapter 309, are building a wood 1970's German designed Sailplane! They are modifying it to accept two ELECTRIC hobby style motors so it can be self launching! Join me as we walk through the steps they have taken to get to this point nearly 6 years in the making!

The german sounds excellent. The workshop is nice.

[@nalakadisanayake5559]

Beautiful workshop environment. I love it. Greetings from Sri Lanka.

[@anandshukla8782]

very nice to meet with Great engineer thank you so much for introducing with Great enthusiastic Engineer.

[@wingnutzster]

The interviewee added a lot of color and character with very clear and simple explanations and a joy in sharing his project and craftsmanship.

[@ExperimentalAircraftChannel]

Darren-Edward Oneill Thanks?!?? Yes... there was a short disconnect on the subject matter for the moment there including the stabilizers on the wall. Sorry if this was a distraction. What can I say... there is still beauty found in imperfections and I for one am truly "imperfect." ;-)But we all strive for perfection... even if it only remains a chase after the wind. Critical eye and attention to detail...make the finer things in life... like aircraft. Thank you for adding to the world your creations as a designer and a builder and as a human being. I THANK YOU for taking the time to watch this video, and maybe others that I produce, and I ask you to LIKE and then SUBSCRIBE to follow along as each and every one of these get better one video at a time. The goal is to increase Production Value whilst the same time be an encouragement to the aviation community. If you are currently building an aircraft...JOIN ME in sharing. I just created a video highlighting that very thing. Check it out and contribute if you would so be inclined. Thank you Darren-Edward Oniell! - Bryan

[@wingnutzster]

@@ExperimentalAircraftChannel I realized shortly after posting that I probably let my bad day get the better of me, was still annoyed at the distraction but certainly don't expect perfection being sorely imperfect myself. The simple truth is I really enjoy your uploads and subjects... keep bringing us the builds that inspire! Long ago sub'd and I always like what I see despite sometimes grumpy impulse reactions. I must say getting back to the build, his choice of installing RC servos raised my eyebrows, I'm fully behind modifying designs especially if it saves the builder time and money (like the foam ribs, something I've employed as well) but I can not imagine the FAA certifying RC electric parts for operation in the critical applications of a man carrying sailplane - it's not the load or stress capability of these servos that worry me it's the tendency to fail randomly with no redundancy design because there's no need in RC. I installed several autopilot systems on a variety of types and the servos and motors or actuators are all industrial and much bigger than RC components in even the lightest experimental. Very special to me to witness wood builds, still the best material for aeronautics IMHO. I wish you were in SA you could report on my builds and designs. Great work

[@ExperimentalAircraftChannel]

@@wingnutzster We are all human... at each end of our keyboards here brother. Thank you for the added reply. I'd love to see your builds and design be it aviation or not. Send me a link here or direct: [e-mail] This isn't just about making videos, building a channel popularity or capturing your attention... trying to build a community and network world wide on things I am passionate about. And make friends along that adventure!

I would love to see an “Open Source” composite successor to the ULF-1 project. It could be sleeker, lighter, stronger, cheaper, faster, and much easier to build.

[@myotherusername9224]

Just build a Skypup and move the seat forward

[@backwardog1]

Built a few RC gliders and single piston planes. Only thing different is the scale. And how it hurts if you have a crash. So neat watch people build stuff that can fly. It will be great to see it in the air.

[@99bx99]

Five years (so far?). These guys have a lot more patience than I do. I built a LongEZ in 23 months while I was working full time. A really nice one too, put 18 air race trophies on my "I love me" wall. I've thought about building a ULF 2 motor glider with more wingspan/aspect ratio for better performance. The designer told me not to go over 10 meters with the span but didn't say why. Not being from Canada or Yerp I'm not exactly sure what a meter is but I guess I could Google it LOL.

[@v.e.7236]

I have been working w/ CAD (cardborad aided design) on automotive sheet metal for years, now. The best template material out there. Nice build and I really liked that design improvement, where he did away w/ the myrriad of pulleys and bell cranks to a simple lever assembly for his spoiler. I don't think I ever built a model plane exactly to its specs, as there always seems to be a better way to do things, given some time to ruminate.

[@joseveintegenario-nisu1928]

What if you test 'Royalite', or the 4mm thick concrete hull kart depicted in 'The Indian Concrete Journal', Oct 2004, pp 43-44, built in Karlsruhe? The B&V-246 gliding bomb had Sorel concrete wings, but it does not admit irons. Gesund +

Thank you Dennis Williams. I appreciate it!

[@1silvervespa]

Good idea ... bit bigger tube and motor mounted into smaller one you could make the Prop and motor pull in side the wing ... .

[@dokmartin5808]

Flying furniture?...i like it.😉👍

[@DrewLSsix]

I have been pondering the possibility of doing a “light hybrid” type setup for an aircraft. It’s a hybrid system GM used for a while, it’s ideal for small aircraft I think because it can be made lighter than most alternatives depending on use case. I think it may help for homebuilts where there are a lack of ideally sized gasoline engines available.

[@ExperimentalAircraftChannel]

That sounds like an AWESOME idea. Weight is ALWAYS a factor of course but it would be something awesome to see! Thanks for watching. If you haven't already... PLEASE Like and SUBSCRIBE for more fun videos like these!

[@shaunsprogress]

Any chance on a follow up to see if it is finished?

[@dejan7837]

Any follow up videos on this project? I'd love to see how this project is coming along.

[@ExperimentalAircraftChannel]

We may be taking a trip back to that same EAA Chapter and could follow up there. Around the Morrisville NC area. Chap 309 I believe.

[@christopherstevenson9737]

Super COOL. 😎. What fun and clever builders. Is this ready to fly yet? Will search YT. Looks very similar to the Schweizer 2-33.

[@1silvervespa]

Thinner foam with the thin plywood applied might be Lighter & stronger for Ribs....

[@edwardhasiak7961]

Very enjoyable video. Do you know when it will be completed? Anxious to see it fly. Will you do a follow up?

[@ExperimentalAircraftChannel]

edward hasiak I have requested they contact me when completed as I would love to follow up on their progress. It is a slow process but it looks like they are getting most of the structure done...so many sooner than later. Thanks for watching and supporting here! I appreciate you!

[@edwardhasiak7961]

@@ExperimentalAircraftChannel Thank you!

[@OnerousEthic]

Update please!!!

[@robertchisholm5133]

Hello Mr. Obrecht! Could you give me some idea of what the cost for all the materials would be, at current ex-works prices? (I'll worry about shipping costs etc. later). Also, to your knowledge, are sets of plans still available and what would these cost? At this point, I just want to get a a realistic overall "ballpark" figure for my own info and others who might be interested in sharing with me the expenses, construction work and the flying, once it's complete.

[@zadrhell]

Never, I mean never use the aluminium hitch or whatever for cables as transfer or tensions hold.....you now owe me your life...

[@scotabot7826]

That's great until one servo fails with the spoiler up on one side while your low and slow on final.. You better make sure you have enough rudder to over compensate for a stuck spoiler. I have been building scale r/c models for 40 years, and even the best servos fail sometimes. Also, there is no way on God's green earth I would fly that glider with the covering stopping only a inch or two past the leading edge sheeting. If there is a sane one in the bunch, I pray they will convince them to wrap the covering completely around the leading edge of the wing. Forget about how pretty the wood is going to look with the stain on it, wrap the darn covering completely around the leading edge, Please. You guy's are asking for major trouble. I assume there will be no rib stitching either, and your just depending on the glue. If just a little bit of air get's under that covering, it's all over but the crying. I am familiar with that "new" covering and glue they are using as well. I am also a licensed pilot of 35 years, so I do have a little credibility. I'm not but an hour away, and I'll help come help cover it! I'm not trying to rain on anyone's dream, and I'm sure its a great flying design, but please reconsider your covering decisions. No one's life is worth the appearance of some finely stained wood. I know the covering and glue has been tested and "approved", but that covering method is a huge huge red flag, even with a VNE of 50. I wouldn't even cover a model that way! Sorry for my rant, I just don't want anyone to get hurt, or worse!

[@g6rcteam81]

I said the same things lol .Us model guys would not get in that thing

[@steilkurbler4973]

That's actually how many vintage gliders are covered. Coming from rc I thought they were crazy, but covering the whole wing adds a lot more weight. I'd still do the whole wing, it's much more durable then.

[@OnerousEthic]

Sheesh, the servos are so light and elegantly simple. Is there no way to make them redundant to address the reliability issue?

[@vincenttremblay-dionne8343]

CFD totally destroying creativity and aeronautics! Great video!

[@jonathanstein1783]

Where can I get my mitts on ULF 1 plans!?

[@daviddowney9331]

What happens when a or both servos fail with the spoiler deployed?

[@kardRatzinger]

As they said, you can still slip it.

[@andrewkeyte1829]

EAC How about a follow up to this video? I am building a standard ULF1 myself and would love to know how Holliday is getting on?

Hard to say. This is a plans built project. And lot's of options on what you can add/change to the design etc.

What is the life of the electric servos? I hope you have some redundancy in there.

[@tinolino58]

Why is electric „new technology“? Isnt it older than any combustion engine?

[@ExperimentalAircraftChannel]

Martin Kaufmann Maybe we should say "new to aviation" as it seems that there is a shift beginning for aircraft (at least smaller aircraft) to go electric. Historically I believe you are correct... just the technology (i.e. batteries) were never advanced enough until now to begin use in aircraft. Thanks for watching! I appreciate you engaging here as well.
