- I Show how to build a carbon fiber fuel tank for my Capella airplane. I tried a method that did not work all that great. Now I know acetone doesn't dissolve foam completely. and now you know! I also show wing cuffs/droop leading edge which didn't help my stall speeds. But I did find out that the Capella can slow fly at 25mph!

Next time, try white styro foam for your plug. Dissolves almost completely . Doesn't shape as easily, but it melts better.
That was a sick little runway hop at the end there! Peanut butter and jealous!
I was having fun!
Come on guys! Let’s get Jonas over 100k subs!!
It's wild how quickly you've gone from not knowing the Capella to landing, taking off, and hop landing again all in like 200 feet in it. I can't wait to see where you go with it!
I believe some may confuse enthusiasm with recklessness. bush flying is certainly more risky than other mission types - but it is also more fun! thanks for sharing the joy and excitement of aviation.
bro i love these videos i cant wait untill my flying school opens back up so i can finish my license great video i love the ingenuity STUDENT PILOT ED
For fittings in carbon, I recommend using a bulkhead fitting and Fay seal the contact surfaces and fillet seal using Pro Seal 890.
Jonas is an engineer, or has the heart of an engineer, along with being one of the great adventure seekers. Always fun and exciting to watch.
Can’t wait to fly Capella!
You two are coherently good people. Thank you for what you do, you make the world a better place.
Hey Silvija Jo, you know you have to make Jonas keep his word and be in the next one right? lol
Silvija Jo,
WE MISS YOU‼️ YALL are a WONDERFUL COUPLE & I Hope 🤞🏻 ALL is Well‼️
🌹💎BLESSINGS💎🌹
I enjoy all of your content, you're both great people. Thank you, and be well
Jonas, you're so close to 100K subs man! Congratulations! I enjoyed seeing your journey with carbon fiber and learning about the pink foam and acetone goo.
I’m so close!
Holy smokes, you did enough in one video to make 3 or 4 videos, talk about productive! One suggestion would be to do more time lapses of your projects, I love watching them even when they're super quick!
Love the strobes, as for the tank, keep working on it - last item you want a failure on - keep it safe 🛩️
Good on you for just figuring it out and making the tank. Working with carbon fiber is not easy especially if you don’t have much experience. Use your network, don’t hesitate to ask for advice.
Brilliant! I love your style Jonas!
I covering the plug with clear tape ..then fibreglass or carbon resin etc. make a fitting hole and dissolve the foam with thinner .. acut the tank in two part and remove the clear tape ..then join the the two piece with materiel
Glad you stayed with the Capella. Fun Bird.
Now plane looks amazing in black. Gorgeous ☺️
wow experimental work is fantastic ..lets see at the competition how it will be.. be safe and see you on the next one..
Hey there I'm DAVID I just wanted to say I love your videos and all the adventures you guys are having! Some day I'd love to get a plane and do what you guys do! Be safe out there!
Excellent as usual!!!
Love the header tank idea and led lights
Love your content! Excited to see the defiance build
That thing is sweet, Jonas! Can't wait to see all the future shenanigans with that Capella in upcoming vids.👍😎
Good to see an ordinary human making carbon fibre parts! Mike makes it look so easy, I must have seen him do it twenty times or so, but I don't really feel I know the ins and outs that a beginner needs to know. Maybe you could do a detailed film of the making of a part for us newbies? Also, what do you reckon the tank cost you, minus the fittings, I hear cf is frighteningly expensive, but have no real idea? Cheers!
it looks like carbon fibre will stay in your lungs forever if you inhale it
I found some decent how to videos, never tried it yet because money
Nice Jonas. I like the new nav/strobe lights. Might try them. Keep having fun. Fly safe
DUDE! 100K any time now! Congrats!!!
Crazy performance!
Dude! This is insane! Lands on a dime!
Look at what Steve Wittman did to the wingtips on the W10 .increased top speed, and lowered the stall. Talking about slow, I flew a J3 cup backwards down the runway in a strong headwind once in ground effect.
wow , Ive heard about slow, but backwards, thats way cooler
@@gregarmstrong4653 it was fun, added power, and landed.
Great work, great video, fantastic flying. Winning
It’s getting better all the time Jonas
Great Video!!!
If your thinking of STOL competitions, have you thought of mounting a small camera (like a car's back-up camera) on Capella's belly with a small screen on your panel so you can see what's ahead of you when you're at a steep angle?
Sweet, my plane is famous. One of the parked planes. lol Heading back your way tomorrow. Lots of trips in the Mooney lately. Love it
You may considering including a grounding strap with the mounting and remove the risk of static discharge fuel ignition.
To test the fuel integrity of your carbon fiber composites, get a sample of your material and soak it in some high nitro model airplane fuel just to make sure it is "hot fuel proof" Be extra sure you don't have a failure in the air. I come from back in the day when we had to build our own models. And yes we are super bummed out about no Sylvia. (sorry for the spelling)
Getting close to 100k bro!
loving the videos
Really like the tank idea, I need to repair/replace a gas tank on a vintage car.
Weld it!
This is why I say it's always worth it to build a mold.
Has the Capella been set up to reduce vapour lock like you did with the Kitfox after your engine starve .
If you are building new wing tanks, you can install baffle ribs with some swing check valves and there would be no need for a header tank (weight savings).
Great vid, good information!
No Sylvia? C- best score. Sorry!
You should be able to dissolve the extruded polystyrene in toluene or benzene or xylene as well as the acetone that you used. You may be able to get a better more complete result with some of the other thinners. Take your time and let the thinner do its work. The paint departments have a whole lot of thinners that will work. Run some tests in small cups. Have Silvija pour while you hold, and wear eye and skin protection, please.
Absolute experimental work Jonas. Doing it your way. The tank fit is perfect. Continue what you do. ✌🏽
The tank leaked and the strobes don't meet FAR requirements. He doesn't think too far ahead.
@@roymoon1 Roy moon take your negative, hater attitude somewhere else..
@@mark675 It's not a hater attitude. If you watch his videos you will see a constant stream of preventable hazards. Like flipping his plane because he rushed take off. Stranding himself 8000 feet on snowy mountain top. Home brew ski jump ramp failure. Now a leaky gas tank behind his head and strobe lights that can't be seen 90 degrees off axis. It's one thing to cook up things for your car. But airplanes parts require a higher degree of quality.
@@roymoon1 ok Mr perfect 😂
The Capella seems like it's really coming good! Bush gear does seem like a good idea especially for competion. Wonder about the brakes too.
I've been very grateful for your wonderful content, and have been watching all the great flying. Wondering what Trent and the other Flying Cowboys think about your enhancements and developing capabilities. STOL races next time will be interesting. Keep on Flying!
CONGRATS ON A 100K!
Thank you!!
Yes! some bush gear is what you need!!
Can you put V G s on the Fin and tail ? Wondering if it would increase your low speed handling ?
I hope it don't leak... "It leaked" hahahaha.. gotta love it .. seems I'm always remaking parts 2-3 times before its acceptable. We all can't be like Mike and get perfection with every part the first time
VERY NICE :-D
I've done motorcycle tanks with blue foam.
Can you see the nav lights from the front and rear if flying directly at your plane?
You need to shape the foam then wrap it with masking tape. Resin will not stick to masking tape. Then do your layup. Once cured eat away what you can with acetone. then dig out the tape that will collect the rest of the foam residue/remnant. Could have wrapped the aluminum with fiberglass. that prevents galvanic corrosion.
Vortex generators under the horizontal stabilizer will help with blanking out the elevator because of the turbulence from the tires in the landing configuration
What evidence is there of - "blanking out the elevator in the landing configuration"?
Only Mike Patey makes Mike Patey Parts!!! That being said love your stuff!
Make sure you get adequate fuel flow from your header tank in a nose up (climb) full power configuration. On my PA-18, I have a header tank on the firewall (left tank) and one located behind the baggage compartment (right tank). By the cub operating manual, the left wing tank should always be selected on takeoff since fuel starvation is possible from the right tank (I think because in a steep climb the right header tank is potentially below the carb in a low fuel situation).
Hey Jonas, the strobe lights, do you just need power and ground and use the same stitch. And do they flex any?
When you make another one gel coat and pva the foam piece that way when you cut it itll pop right out.
Gel Coat will eat the foam.
@@howsmyusername1 It shouldnt.. atleast it doesnt for me and I do it like everyday.. I use the duratech black
Hey Jonas the gasoline may eat the rubber grommets. I had rebuilt a fuel pump and the gas changed the shape of the rubber o-ring and dissolved it. You should check the tank with fuel in it for a few days before installing the tank.
Nice job Jonas, well done. So does the Header Tank provide an anti-cavitation fuel feeder that remains full on a 45deg bank - e.g. ? So now both wings feed into this new unit and are there still two feeds to cyclinders? Really love your channel with fabulous content. Thanks 🙏 for the learning and entertainment. Pete
nice hop!
Try the blue foam from Lowe’s, I had the same trouble with the pink stuff
Well done Jonas. Nice that you are trying new things.
Thanks, Jota.
Will the new fuel take change the CG when full?
Why taxi to the apron when you can fly there instead! Absolutely love it!
If you drain all the wind fuel, how long can you fly on just that small header tank?
Where did you get your carbon supplies?
Hey mate you have probably covered it but, why did you sell the kitfox and go with a capella?
He's building a new plane of his own design and had to raise some cash. Kitfox is a seller's market airplane right now. BUT they have to have something to fly in the back country 'till Defiance is finished hence the "bushing-up" of the Capella, a plane that he built some time ago.
Can you try using MEK to dissolve the foam.
Can't find the green light from the link
Is that a Quadlock case for your phone in the cockpit? (wireless charging?)
Fuel won't eat away at that carbon fiber? Or does that coating prevent that.
Sweet! Are you gonna make Arkansas Stol?
Have you tried 2lb bead foam? It’s denser and sands probably good enough for fiber coating. And dissolves in acetone.
Just for testing Jonas you better rig up a bypass from at least one of those Wing tanks. This would be to make sure you haven't developed any crud in the outlet lines from the new header tank.
Getting close to 100,000!
Just a few more!
Hi Jonas,
did you use the right resin wich is fuelproof?
The ordinary epoxy isn't!
Nice work Mr. So are you gonna remove the leading edge and get your top end back?
All of the clips at the end of this vid were with cuffs removed. Top speed was regained with no low end penalty.
Can those strobes run on a 3c lipo battery?? I’d love to put those on my Scout Carbon paramotor.
Do you know that Lockheed Martin failed to make a composite fuel tank for the X33 and that sank the program. It is on youtube.
If you get one of those lufa cutters (the pizza wheel cutters) and trim some carbon fiber @ 45° about 1/8" of an inch long...you'll have a little pile of carbonium fibers, you can mix this in with the microballons and it will GREATLY strengthen it. Don't add too much as it will be too hard to work with.
How much was maintenance cost on Kitfox? I am a younger private pilot and was thinking about making the investment.
Looked like fun at the end! Silvija...... where are you?
What engine you running? Thinking of buying one. :)
How is the new plane coming along?
Now get rid of the landing gear cables to free up the absorption capabilities of the spring gear (let em whip!) and let some air out of the tires for smoother roll over rough terrain! Is adding a high travel gear worth it at this point? Everything is a compromise - add more complexity, weight and drag for a so called bush gear, or stick with the simple and tough heat treated 6150 alloy spring gear that you have for less drag - the stock gear seems to have absorbed your previous meteoric impact with the third planet from the sun without any trouble, LOL! Your choice!!!! :)
something to consider. Carbon fiber conducts electricity. If your tank isn't properly grounded, you run the risk that electrolysis will remove the coating from the inside of the tank.... I just had that happen in a metal tank, stray voltage from the fuel sender removed the leak-prevention coating (in big sheets).... will it be a problem for you? I don't know, but it is something to be aware of.
Only in Emerica!! You couldn’t do that in the UK. I’m surprised you didn’t ask Mike Patey?
SLOW FLY @ 25 MPH! OUTSTANDING!!!
Maybe you should try using eps(white) foam instead of xps(pink) foam, may make a difference. Xps is much more dense generally and I imagine it probably doesn't melt as fast.
How a bout tig welded aluminum?
Is the weight saved with using carbon fibre worth the extra cost and trouble over using alloy. I once made an alloy tank using folded seams and with flushing sealer it did not leak. With you being on the lean side you have a built in advantage over some of the other pilots in the STOL comps AUW is what counts and the pilot is a big factor in this. Nice instructive video. Regards, Jim in NI UK
Great work on that header tank. :) Nice try on those cuffs. VGs might help, or even retractable slats. I wonder if "BOUNDARY LAYER CONTROL" (B.L.C.) might be the ticket. On jet aircraft they bleed compressed hot air from the compressor section and run it over the top of the wings when extra lift is needed. How to do that with a "RECIP"? I'd bet there's a way. Might be a lot easier to install rather than slats.
@@francisconti9085 You might be onto something. What about running a turbocharger and bleed air from that compressor through a heat exchanger on the exhaust, and then pipe it up to the upper leading edge of the wings? Might be a big enough volume of hot air to work.
Any RFI generated by those Amazon strobes?
I used some inexpensive LED strobe lights on my pickup (first responder) and they wipe out my VHF radio when they are on.
Try ferrite cores to clear up the radio.
Those strobes do not come close to meeting FAR requirements.
@@roymoon1 so you've tested them? The far simply says where they need to project light and how much min. In some cases a tail position light is needed as well.
I just hooked up 2 6in LED bars on my sons power wheel. That EMF must be large because my FM radio was 15-20 feet away when I turned on the lights they knocked it out.
Hey Jonas
Bad idea using tank slosh sealant. Cases documented of it separating and blocking the tank outlet followed by a deafening silence!
I believe RVs have an AD for it to be removed from any tanks on their models.
Agree
Cliff Williams I agree. Once it starts separating, you’re in for a real mess, that is if it didn’t ruin your day while flying. Composite tanks really shouldn’t need slosh.
For safety I would toss out the first one and go with another to get it perfect.
Great, Informative Video‼️
Reading the comments, it seems several folks have alternative ideas. It is nice that you acknowledge them and are open to trying them but Your Knowledge and Research is already exceptional‼️
Mr Roy Moon: please lighten up- last I checked, You are not God‼️
Thank You for your videos‼️ We miss Silvija Jo‼️
Hey partner, I just installed VGs on my cygnet (if you know what that is). It did stall @ 41mph, now it doesn’t stall! It runs out of elevator at 35mph, but doesn’t stall.
That’s what I like to hear!
Now I need to do the elevator and gap seal to see if that helps.
Aluminum fittings will corrode quickly due to the galvanic difference with the carbon fibre tank. You need passivated stainless or titanium fittings. Alternatively you need to electrically isolate the aluminum with layers of e-glass or s-glass.
