Flew the Abandoned Airbike to the House. 

You's two have made a beautiful baby. What a happy family. 😊

Jonas, When I had my AirBike I replaced the Rotax 447 with the Hirth F23 50hp horizontally opposed engine, and it was perfect for the plane, and made flying it so much more fun! And reliable, too, no issues with it at all for three years until I sold it for a bigger plane.

You two have a beautiful child. Merry Christmas

electrify that thing :)

Good show. And more importantly a beautiful little family.

Congratulations on getting the air bike home. That sure is one cute little girl. You did well with both of them (girls).

There are a couple of ways to reduce your motor temps with 2T motors, but you should keep in mind that cooler weather will lean out your fuel/air mixture. You could use a premium synthetic 2T oil in your fuel, which will help keep temps down. Also you can adjust your carburetor, a richer fuel/air mixture will keep temps down. A third way to manage your temps would be to adjust your ignition timing, retarding the timing can help combat some temp issues. I almost never trust temperature sensors when it comes to 2T motors, because the material composition of your piston(s), piston wall(s), and ring(s) can also affect how hot the motor can run. Great little airframe, I enjoyed watching it fly!

Glad you finally got your bike Home. Thank you for letting us see your little girl, She sure is a cutie and i'm going up too fast Hope you and your family have a merry christmas.

Hello I had the same problem on my snowmobile it was the rubber boot that held the carburetor on it had a crack so it made one side lean and head temp was too high

Keep the flying vids coming! Whatever happened with Defiance build or the Capella?

Best part was seeing your Beautiful Family. And it was fun to see you flying and scheming how to fly higher and faster and further. :) Merry Christmas and God Bless Your Family.

Somebody has to know what to do. Some sort of add on cooling system ?

Big big smiles! such a beautiful family. Merry Christmas!

Cool video. Thanks 4 sharing Jonas. Cheers !😎😎

I would go with a Yamaha Phazer engine with the Skytrax gearbox it's a perfect fit for something like this and it gets you a four stroke engine.

Beautiful baby Ava, beautiful mama, beautiful family. Because I liked'em back in the sixtys, were it possible, I'd build one of the refurbished conversion Corvair engines and the plane around it. There's been several promotions cross my screen however I don't find anyone posting videos with them. Ecen though they're supposed to be less expensive than foreign made alternatives and very reliable. Wishing y'all a very Merry Christmas, as yer mightily blessed. Thanks for sharing your family and flying. 🙂😉🙄♥️

*Where is all the snow???*

Y'alls little one is growing so fast. She has the most beautiful blue eyes I think I've ever seen. The wife and I fell in love with her. We'll have a new grand daughter next April from our younger daughter. That'll make grand child number eight. Four boys and four girls.

Awesome seeing Ava in the plane for the first time!!! Start em young

Nice to see you, hopefully you will find a more reliable engine. Your little Ava so cute 🥰 merry Christmas.

Stoked to see you used the video, that's pretty cool!

Leaky crank seal

Awwwwww……..you got a future little aviator on your hands there! 🥰 So precious!!! I dig the Airbike! I agree you need a worry free power plant though. Flying should be fun, not nerve racking. Love you guys!!! 🤠👍

Adjust your slide needle clip down one notch

Glad flight went well - what a joy to see your beautiful little Ava, growing so fast too. Yes, another motor may be a good scheme.

So nice to see you so happy, I wish you a lovely Christmas. Definitely get a better engine!

Have you looked into the 4 stroke v twin that aeromarine is selling? I'll see if I can find a link

Had a Rotax 277 powered Airbike but not for long. I bought it used. Trailered it home to the high desert. Got it flying and headed west to buzz a friend about 5 miles west and maybe 400' elevation higher. As I was going the ground was coming up to meet me and about halfway there I turned back realizing I wasn't going to make it before I flew into the ground. I had reached about 2800' altitude and achieved more than max service ceiling with that 1 cyl rotax vibrator. My heart was in my throat as I made the shallowest right turn in aviation history fearing contact with with a tall Joshua tree was in the realm of possibilities. As I got going back east the ground gradually started to fall away to my relief. Arriving safely back at home base at 2600 elevation, I started shopping for more power. I made a poor choice but that's another story.

She's already to fly❤

Living the dream! My goal is to have a rural property with my own runway and hangar!

Before replacing your engine I would turn that gearbox down to see if you can get more airflow to that head... simple fix/try that won't cost you anything.

There´s a first time for everything, bringing a plane home and youtube-comments.. Nice one, keep em coming! Didn´t you buy an old Yamaha snowmobile some years back, that engine would be something to put on that bike 😅

Get the plans and build a 1/2 VW engine 🙂

This kid with flying eyes.

How wonderfull and accessible is the dreams when you live in a great country like USA. Its almost impossible for normal ppl here in brazil to have a nice house, hangers and planes... congratulations! Greetings from Brazil!

Always fun to watch! Thanks and Merry Christmas!

That thing needs a phaser engine with a skytrax box on it! Your hangar setup at the house is so sick!

Awwe, Ava is so cute. Btw, when I first saw that screenshot picture of Ava in your lap in the plane, my first thought was “Silvija is going to kill him if he takes her flying!” 😂😂😂 Cool plane!

Another entertaining video Jonas. You have a budding little pilot there, she couldn’t take her eyes of the air bike, she was loving it.

I remember earlier videos when you mentioned the cylinder head temp issue … but so many other things were going on with your build that I never thought to ask, whether the mixture in that particular cylinder, is always leaner than the mixture in the other cylinder 🤔 - You can see where I’m going with this. Ps - Ava really is stealing the show 😊

the new 4stroke that badland aircraft is using is a tiny powerhouse id love to see a video of some of the options ur looking at maybe the hirth

Man, that looks like a fun machine! I like paramotors, but that looks like a whole other level of fun.

That's awesome brother Jonas ! Love seeing you flying a plane of your own again. I would love to fly my Rans Coyote II up to your place some day and go fly around with you. Thanks for another great video, you are a good father and husband to your ladies. Merry Christmas !

Theres got to be one simple little fix with that over heating issue. Ive had nothing but fun flying with my 447... I love it! Ive let it sit for a year and she will start on the third pull.. always runs cool too. But like I said, it has the belt driven fan..

Check your carb boot. Bend it in all axis while squriting starting fluid on the boot. If it revs you have a leak. Also make sure the carb is level in flight. An angled one is flowing different fuel streams into cylinder

Beautiful multi lingual mom and now baby too. Keep them safe and replace the engine. Merry Christmas and happy holidays

I both that set and clued them to my NACA 23012 wings before the first flight. My buddy told me" Test is first whitout" I think I´m not much of a tester after my demise so I put them in advance. And greetings from Finland and Merry Cristmas to all who suffer from aviation bug. Thanks.

Look at the thump-air 4 stroke from Badlands aircraft. That would be the engine I would want to be behind in a part 103 machine.

AVA is soo cute...does the air bike have folding wings? love to seee someone do a 4-stroke conversion, like the thump-air 460 from badlands aircraft or the 4-stroke v-twins like kohler or gaokin

Excellent video Jonas. Pretty neat how you lift your airplane for storage. And appears little Ava is showing left handed tendencies. Welcome to the club Ava!

Everything looks to be going so well! Merry Christmas to you, your family and fans Jonas.

Nice to see y'all, what a lovely little family, and pops still doing cool stuff. (With a realist budget) Love it! ❤

I'm planning to fly my kolb to my home hangar soon. Both anticipation and hesitation are present..

Please replace that engine. If your constantly worried about that engine that is the first hole in the swiss cheese. Please take it from an old man, if it doesn't feel right, its not right, at least for you.

The temps are your deciding factor knowing you you will try something different which may change the aeroplane for the better in performance but you will conquer this im sure happy christmas to you and the family

Like Colin said. " you're living a dream " our dream . . . have you ruled out the cht sender ? Thanks, Bob

Happy to see you flying again Jonas! Merry Christmas to you and your beautiful little family.

My BP spiked when I saw the thumbnail pic with Ava in that heap! Thank god it was a photo op, and you didn't actually take her for a flight!😂

Merry Christmas folks...you have a awesome family and start in life...

Nice to see a Skyranger in the background!!!

I have had many TEAM products over the years. Flown a 337 Airbike and 503 airbike. The 337 was minimally powered and the 503 was awesome and perfect IMO.

Cool dude! I been flying again finally. (had to delete my Instagram because of spam so not able to post any pics outside of facebook)

Snowmobile engine we ran dual carburetor with different jet in each carburetor

Seeing you buckle in reminded me of the time I took off with the belts dangling under the plane! I made sure to fly "smooth" back to the runway!

Your cylinder temp concerns? I was wondering if the Cylinder closest to the work, the propeller should be the hottest. The work from the other cylinder's next to it, the temps will decrease in cylinders as they're farther away from the Work/Prop? Make sure the color of the plug on First cylinder is RED/Orange. the other should follow

Changing the size of the carburettor needle jet will fix your problem. This jet is for cruise, the main jet full power and the idle jet for idle. For example If the needle jet is a 270 put a 272 in. The larger number indicates a richer mixture.

Must be very satisfying have an aircraft at home, always thought it was supposed to be a hangar, but then it filled up with agro machinery, so glad there's room!

First off a resounding.... MERRY CHRISTMAS ! ! ! from your biggest UTAH fan....! And it appears to me that yer part of Idaho is have the same "Indian Summer" weather that we are here.... Which i personally am enjoying IMMENSELY ! ....altho' some snow Sunday night would be nice.... If only WE could "ORDER" when and what we want for weather, life would be almost perfect, aye? Airplanes and your flying adventures ARE what made me start watching you guy's channel, but after Ava's coming, she is now what really puts a smile on my face ! So THANKS to U2 for including her once again ! As she was watching you out the window i can just image what thoughts were going through her head.... "Mama, a VERY LARGE mosquito or maybe it's a Dragon Fly?.... just landed on the front lawn ! ....and Daddy is riding on it ! ! ! Maybe someday he'll teach me how he does that !??! .... Let's go ask him, Mama !" She is just ADORABLE with a capital A ! .... for "Adorable Ava" !❤! 2nd... Thanks for explaining about what those litttle reversed "Shark FIN" looking things are and do! I think i fist noticed these things on Draco....? But to be right honest, i thought they were just something Mike put on just for "LOOKS"! (.....🙄.... Us non-aviator people are Soooooo STUPID !🤣! )....but not any more !😀!...👍 One more delightful vid from U3 Idaho Musketeers ! Here's hoping that y'all have a fabulous 2024 and being is selling for your ride‼️❤️‼️

There's Jonas livin' the _dream_ !

Thanks for the update! Your Daughter is such a cutie, brings back memories of my daughter at that age. Merry Christmas!

Thats it, Ava is officially a pilot now. Hahah

💕💕💕

2 strokes are extremely sensitive to air leaks. They can cause a lean mixture and therefore higher cht, check it out.

Какие Вы молодцы! Всего Вам хорошего! Приятно смотреть Ваше видео. В Вас много позитива! Здоровья Вашей малышке!!! 💕

Hi Jonas, I had a Fly Products Paramotor that was 2 stroke, I had set up EGT & CHT on it & I found that it didn't like being held at a constant RPM and actually ran cooler at full throttle or if I played with the throttle up and down . I also had a Yamaha 2 stroke enduro back in the day that was the same way . on a highway run it would heat up if held at a constant speed for more than 5 minutes but if you varried the theottle up and down like you were off road it worked fine and did so for the 10 years that I owned it.. anyway maybe its just as simple as playing with the throttle while flying , just like yanking and banking ..

To get more yaw stability, try covering the sides of the rear fuselage. Thin plywood?

Awesome dude. Beaut of a kid too! Working hard pays.

Any more abandoned airbikes out there? Sweet machine! Beautiful family!

This would be a great candidate for an electric conversion. It looks like Top Rudder is going to be making an electric version of their 103 Solo. I'm looking forward to seeing electric ultralights in the future!

Love it.

Airbike is at the top of my want list,... nice you have a clean looking plane.... someone needs to bring theme back to the forefront of part 103 and offer the Hirth F23 up front........ can you see a Flock of these doing a mass arrival at Kosh. ? ..... cool bird.👍👍👍

Congrats dude! You’ve worked hard for that setup, it must feel great seeing a plane in that hangar!

Hi mate. Great to see the family. Looks like Ava will be a pilot. All the best for Holidays.

How good Jonas! good job! and congratulations for your family, your son is beautiful and he is very big, greetings from Quito, Ecuador 🇪🇨

The airbike looks really fun and the hanger with the new door is super nice you worked hard for it and deserve the reward

comment on the VG's and how well or not they worked???

Good to see you got it home! Merry Christmas to you all... maybe Santa will leave some ski's for the Airbike under the tree!

The air bike has been a fun diversion, but it’s time to get to building (or buying) a 3 seat plane to take your family on adventures.

So good to see you flying again. Hope you can get a plane up with the family soon. Keep up the good work!

Merry Christmas Jonas Sivlja and Ava from John in Sydney Australia. Well you finally got the flight characteristics of the airbike normalized: I'm still at Orr with the hanger door design. 🌲🛩️

My 63 Sporster always ran two different sparkplugs to adjust the heat range. The back jug on a Harley doesn't get the cooling the front jug gets so it's normal to run a cooler range plug in the back. Has anyone experimented with different heat range plugs on a two stroke?

There may be two separate problems relating to your high temps. I flew a Kolb firefly with the Rotax 447 for a few years and although the top end tuned up nicely, the EGT’s would spike in the 4,000-5,000 rpm midrange. I worked with a knowledgeable Rotax engine guy that told me that the Rotax 447 was a bored out 377 and the port timing was off enough to cause the high mid range temps on the 447’s. It certainly was the case with mine however I have not flown any other 447’s. The top end high temps may likely be a separate issue. Just some thoughts FWIW. BTW, the baby is adorable.

Nice

Fun video but I will join with others in asking you to get another engine! I did spot a windsock at your home, though, so that's a good thing. Always nice to see the Fam.

It’s great to see you in the air again! Why not get a rotax 503? Those are proven reliable little power plants… or maybe a 1/2 VW? I’m on this heated jacket…. I have an open cockpit biplane and a heated jacket would be great!

My 447 on my aerolite 103 has a belt driven fan in the shroud like a snowmobile.. but it's a pusher prop so it kinda has to.. probably can't do that on that engine because the belt drive would be on the back.. hmm 🤔

Ava is the cutest little button.

😂 kid looking down "Ma!! There is a madman on a flying bicycle, on our frobt lawn!! "😂

I still need to find the old TEAM Aircraft promo video. I had it on VHS and converted it to an MP4

Great Video!
