BUILDING MY NEW AIRPLANE. (The Fuselage) 

You could have just talked to her then called *us* back later. It wouldn't have hurt my feelings.

Yes! Love it! I’m an aero engineer and I fully support you and Wilson. Don’t let the haters (I predict there will be about 1,000,000) tell you that you don’t know what you’re doing. They’re just jealous that they don’t have the balls (volleyballs) to try something epic themselves. Super stoked to have another build series to follow.

Jonas: "I'm just kidding guys" Me: "Thank god" Jonas: "That was all Wilsons idea" Me: "oh no"

I love the design of the whole thing, especially the landing gear!

As sad as it will be to see the Kitfox go, I cannot wait to see this project unfold!

This is gonna be interesting. It’s always fun to see an aircraft come to life. It is definitely a learning process. Can’t wait to see the process in action.

Great stuff Jonas. Can't wait for the next installment.

Living the dream!!! Jealous and excited for you! I have always wanted to design, well finish my design and build it! Super stoked for you man!

Loved the video Jonas!!! Hilarious with Wilson and the video effects awesome!! Great work, love the enthusiasm and excitement for your project!! Get after it!

Excited to see the build progress. I am building a tube chassis rockcrawler currently, and a plane is the next project on the list!

Hey Jonah glad to see you starting on your dream it's been a day day and a half since you first showed us The Jig the ball is definitely rolling great content it will definitely be exciting to watch that step by step build thanks for sharing

Had those moments when I may have been out in the shop too long as well, but my buddy is Spalding as Wilson is already taken by Tom Hanks..and now you, ya gotta watch him though, he started hiding tools on me towards the end, and I'm pretty sure he was into the liquor cabinet often as well ;) Good to see you back on the project, now get 'er done!

Jonas- Good on Ya, Brah! Nice to see that you have more skills than just totaling aircraft. Love the fact that you design/built it, Scha-weet!!! Love the alternative ideas for load bearing, and- hope that the aero tricks incorporated work! Like the simple gear thoughts, and, drag reducing ideas. Bet it's gonna be fast!!!

I use to fly Cessna 152's and 172's with friends and family and they used to let me fly. I have about 12 hours of recorded flying with instructors. I never actually got my solo license and I regret it. Your videos make me miss being up in the air. I like your videos.

Enjoying watching you build your new plane. It’s gonna be a nice one. Have a good one. 👍👍👍❤️

Jonas, is there anything you can't do? You're amazing and so is your girl. She's a keeper.

Full marks for whoever invented it , because this "Stol" drag thing, seems to be exciting a lot of interest , and subsequently a LOT of COOL innovation . General aviation , pretty much static for generations , is evolving more rapidly now ,than at any time since the early days of flight itself .

Oh Wilson... you crack me up dude! Nice work on the project and video!

Can’t wait to see the finished product, great job keep it up looking forward for the next vid

Really enjoying this Jonas! Be watching you 100 percent building this plane! Careful as she goes!

keep the build videos coming! We will surely love this journey just as much as any flying adventure!

Hi from Australia, nice work mate keep it up.

Cool details. Thanks for the inspiration and keep on trucking (from France)!

Sounds great ! I used the gear idea for my Bush plane from the piper tripacer, the bungie's and the Rebound shock are all tucked up inside :)

Yes!!!!! Thank you for the video!!

Sweet camera work!

I am burning up a lot of valuable time watching all you guys live my dreams, good luck, be safe and keep up the good work

I’m sure you know Champ, Citabria, Decathlon, Scout aircraft. They all use three longerons in the empennage. Been doing it around 80 years. I see some other Citabria influence on the cabin braces with the “y” on each side in front. Fuselage looks like it should be really strong, but light. Good work!

Video was fantastic Jonas. For so many reasons. Call yourself a rebel, then put a Murphy Rebel crash clip in your video (which has design ties to the Beaver) and of course Wilson! Btw the rebel does not have the cross bracing because it's semi-monocoque design and has a square cage in the cockpit area made from aluminum square tubing that the firewall ties into. Rebel is a legit backcountry airplane as well. That was a harsh attempt at landing. Keep 'em coming. Great work and good luck with the build

Can't wait to see the build process.

I'm so excited for this build. Your videos are the best!

The build videos are cool! Can't wait to see it done.

This is making good progress Jonas. As far as the landing gear is concerned, think of the lever effect on torsion as you will increase the length of the gears. You need to design them so they have good torsion control (a bit like your fuselage)

Epic! Please making these man! I want to see more building!

Jeez a lot of bro science and gut feeling in this, it's like your welding up a go cart.

My dad’s 1994 Skidoo skandic II actually had that exact suspension setup you talked about in front end. It was an oddball for a snowmobile but worked quite well actually.

I enjoyed this video, love watching builds 👍

Sweet Vlog Jonas!! Nice seeing you continuing the work on your dream bird!! There will be trials and errors!! Keep your wits about you bud!! You have the internal drive!! The beard really works for you!! Quite awesome actually!! Getter done son!! The day you get to sit in it and turn that key and bring her to life. Well,,, it will be because of you!! She will be truly a part of you in the air!! I will Be following you along the way!! Giving support as you progress!! For now you get a 👍👍👍 up!! As always Jonas! Fly Low,,, Fly Safe,,, G -Man

Yesss !!! Get after it ... This is gunna be awesome !!!!

Keep it up Jonas! Great seeing someone fulfilling his dream without the help of a hired camera-guy and tons of money...

been waiting on this video haha looking great i'm sure the gear and the fuselage bracing up front will do good

This is the first video I've seen on building an experimental! nice! (As long as it is safe.)

Looks cool, can't wait till it's done. Nice filming📷😁 And I like the name.

Awesome 😎 Looking great and look forward to the journey ✈️😊👍

Jonas: I'm not going to film close-ups and slow-mos cuz it takes a lot of time. Also Jonas at 4:20 Lol. Nice work!!

Jonas, I think you were on the right track early in this video when you were talking about the triangle vs the square frame. The triangle is inherently one of the strongest forms in nature/engineering/whatever you want to call it. Making it fit your needs in the airframe may be another issue though. Applying it to a practical fuselage might not be all that easy if you want usable space inside. The project is looking really good. We'll be watching... (I've been wearing a beard for more than 40 years . My wife of 38 years has never seen me without one. When she saw an old photo of me in my Navy uniform, she asked, "Who's that kid??") ;^)

Please let us know before your next builds, I'm sure the community would get you some quality grinders instead of the harbor freight drill master... I may just send you a couple of ours to get you started. Great video and look forward to much more from this build!

I miss Sylvija .Thanks for the video.

Great progress! Another amazing designer used the defiant name.

Awesome to see you getting some progress on Defiance! FWIW- Mike Maiers has been doing that cantilever style suspension on cars for a long time and it works amazing. I understand, they are cars and don't technically land, but it works way better than typical suspension as far as rolling due to side loading. (Car guy wishing I was a plane guy to)

He hasn’t said yet, but I think that’s what mike is going to with the gear too. It’s my favorite gear concept too. It rattled around in my head for a while till I saw it in a museum. Cool stuff dude.

Love your work mate. There is something about designing your own thing the way you want, by using what you like about other aircraft’s designs. My Frankenstein is built the same way. Cool stuff!

And the Epic journey continues... next phase. Thank you for the awesome editing and time laps. I'll be watching. ;) ~ your neighbor

love it!

Super impressive build - way to jump right in! Just a suggestion - if you want to put some real numbers behind the hunches about what adding/removing/re-sizing certain tubes will do in terms of torsional or bending stiffness, Solidworks has a great module for evaluating the strength of tubular weldments. I think you can get a free seat of Solidworks as an EAA member, and I can send you an example of a bushplane fuselage analysis I did. It can be really surprising what you'll find.

Good one. I loved Wilson.

Thanks for keeping us posted about the progress. I love the plane's name! Are you willing to give us a rundown of costs as you go along?

I loved the middle part with Wilson! That was hilarious! I think you spent a little too much time in that hangar! Ha!

I have designed and built race cars with exotic suspensions. You have a great design and I was wondering when somebody would finally do that on a STOL. I thought Mike Patey would. Follow Mike's lead with a carbon fiber carbon fuselage for strength and safety. Speaking of safety, please consider braces or mounts that will direct the engine away from the cockpit for a 60 mph or less nose crash. If competing in STOL Drags, I would consider rollover protection (I know... extra weight) in case you catch a wingtip or landing gear when you slip at low altitude to reduce speed. How about massive speed brakes instead of slipping? GREAT NAME, by the way. Keep this build vlogs coming, they are great.

Your emphasis on running the tubings full length for structural integrity to compensate for the torque developed at the higher HP and speed is a lesson to be reckoned with. Maybe Yogi-scout will someday meet Defiance. Thanks for sharing, MJ.

Love the build videos keep it up!

Impressed you have the patient to build your new SPEEDY STOL DEFIANCE. Greetings to your love :-).

It's coming along nicely,now Wilson has to get his ppl.

Man, I can't believe you hung up on Silvija just for us. Can Wilson mig or tig worth a crap? I enjoyed the tech talk, the smoother gear sounds great. Now, back to work!😆

What a stud, Skidattle !

Nice work bro! Hopefully Prof. Patey gets to see this and sends you a little feedback!

Rad! Can’t wait to see the next video!

Great video bud 👍🤠

Trent, In regard to the gear design, keep in mind a potential safety issue with legs in a crash. Had a good friend lost in a super cub when he was trapped.

for a little added security for your frame in the ceiling put some come-a-longs in place. Takes away from the crash factor. :0)

Yea baby, Defiance great name because if you named it- I really put a lot of thinking in to this plane! Would be way to long of a name. Even if this is how it evolved!!! Love it.

I'm definitely going to make a plane!

that's super cool cant wait to see it with some skin!!!

Use air shocks or struts, connected to a small air tank, 3:12, for the suspension. With a large air line connecting the two . With a fast acting solenoid valve in the line, possibly closing the valve will instantly stiffening the suspension on the low side. Sensors can make activation automatic. Basically a pneumatic anti-sway bar. Or actually usea away bar! It's not the best with long travel suspension! I was thinking of a slightly larger lane, same style, with similar suspension, with the ability to retract, just like as if in compression. Then just keep going. Until the tire is inside the fuselage, Or up tight against the exterior. With a aerodynamic wind deflector around it. Use a turbocharged twin or triple rotor, Mazda style engine with modifications. Capable of 600+ HP, but detuned to around 300-350, getting one of the liquid piston style engines would be better, or post a turbine engine from a surplus military helicopter get a planetary gear reduction built with the option of possible contra rotation , or better yet go electric. Use two Nissan leaf motors, or a single, and construct a basically a deployable wind turbine, so the battery can be range extended, by slow climb and dive, generating power on the dive. Use a lot of carbon fiber, to lighten as much as possible. Crazy ideas, but the pneumatic sway bar should work great, it may require operating it differently, using added pressure to reduce sway, but a simple system, then again it could also use hydraulics in the same way only the valve closing , restricts flow, a hydraulic anti-sway system!

After thinking about your inboard shock absorber system, I realized you need a sway bar to connect the two struts. Without the sway bar (assists in allowing cars to corner flat) it is possible to suffer the Draco takeoff crash when only one side of the suspension compresses due to a crosswind. Also, I'm not sure about the copy of the Capella fuselage for torsional stiffness with a 350 hp engine. Maybe a 100 to 150 hp engine might be okay, but the Capella wasn't designed for hot rodding. I think you should follow the Scrappy build and cover the birdcage in carbon fiber. Then you should be able to handle Scrappy (500hp) power. Actually, a carbon fiber monocoque design eliminates the birdcage while saving weight and increases strength. (Your next build) ..... Back to work

Nice job! I love it! It's the only way to keep a frame straight. But you've definitely been working too hard. Even Wilson says so. Yeh, we have an inside channel! Love the beard!

Good luck to you will be following your progress.

Good luck with your build.

If you get tail shimmy, then ..maybe add some tension wire from the cockpit to the tail structure's tip? I've no idea if that works for airplanes, but in other structures of light design, whenever you observe a tendency to move, you strap it with wire (if the project doesn't allow for more structure to be added). Best parts about using wire, it's light, and you don't need crazy amount of tension on it, just enough to cure the wobble.

You may want to look into the tapered spring gear legs like the Wittman Tailwind has. Good luck on your project!

I like your fuselage design, and a lot of what you say makes sense, and if has been done in the Capella, then that's even better. That triangular tail section though - I want to add more to that single tube top :D

She is really coming alone, great work, it’s awesome that your designing your own plane, I’m working on a 37% Pitts challenger that I have modified from The plans a bunch it’s gives you certain level of accomplishment. Can imagine the hour you spend in cad 😂, so you have some cad pics you can share?

great work

Do the kit-fox suspension, just use a cantilever lengthwise design for yours. Shocks get hidden inside the fuselage, forces get distributed lengthwise, weight distribution is up to your needs (longer or shorter tie rod after the lever brace (or however it's called), what's not to like? F1 does it, they face the same issues (outside of shocks, but that's not an issue considering desert racers use it and they're just fine) as you do. Air travel, weight distribution et cetera.

Crazy. Subscribed. I want to build one one day. I’m following this. Keep the beard!

The Wilson bit was hilarious!!!!

Good Job!

You through in the slow mo grinding. Lol. Build it and they will come lol. Field of dreams. Nice work Jonas.

Damnit, now I want to build a plane! But seriously starting to get my pilot license because of your channel. Thanks for all the inspiration.

Nice work Jonas. I also came up with that same gear idea and then discovered stinson had done it before. I'm not as clean sheet as you are with your design so I've had a harder time incorporating it but who knows, maybe one day. I'll be interested to see how your design comes together.

Awesomeness bro.

What if you could have a "lock out" shock for take off? Locks compression in high cross winds?

Wilson: that was awesome..

I am glad i found you, definitely following you.

You are cool, man! Great respect to you!

Looks wide enough for side by side seating, a word of wisdom, make the cockpit super comfortable with heat with all the creature comforts that Sylvia would like. Old saying "Happy wife, happy life."

You should also look into cantilever style suspension too to save space it lets you use a smaller shock 😋 if you use a 2:1 ratio triangle you can have twice the travel. They use it on Traxxas revo suspension too 😋

There is so much in that fuselage that I would do the same, triangle back portion and horizontal wing main pins.

Can you do a walk around video of your Capella?

Holy shoot I died laughing at 5:18. I'm thinking Jonas went crazy in his basement with this build... Then he brings out Wilson! OMG dude pure gold bro, pure gold.
