Flite Test - EDF Afterburner

A Vampire Mk6 modified with a real working EDF afterburner! Powered with butane and ignited with parts from a stun gun, David attempts to fly this EPO foam RC airplane with real flames shooting out of the exhaust tube!

Ah, the old days of flite test. Can't believe I was just a kid when I watched these videos back then

[@DominicGreen432]

Haha same here for many of us!

[@htpjay0927]

Same

[@mr_moose4529]

I was 5

[@James-C24]

I was 15 ah the good old days

[@defenestration5008]

Yup same here This was one of there many videos that amazed me

[@mysterygamer48]

Oh the nostalgia coming back to these videos 6 years later

[@djay6651]

That things sounds like a full sized jet.

[@maximvm945]

Yes and its looks cool

*You could actually make it much more reliable, fast and increase its life expectancy at the same time by having the coil wrapped around the metal tube that protects the polystyrene*, it would keep it cool while the afterburner is on as well as make sure the fuel is turned into a gas reliably, and remove the need for the heater, improving flight time in cold weather, and canceling the slight weight increase due to the additional tubing. Additionally, now that the protection tube is cooled by the incoming fuel, you could put in a bullet type cone in there to actually generate thrust from the combustion just like an actual afterburner would, making it a true afterburner.

[@TheUlitamateStunt]

Somebody needs to sell EDF afterburner packs using that design, that would be incredible.

[@terranovarain2183]

Yeah that would be so cool and definitely would work

[@wojtik1980]

I spent my teenage pauses at the secondary technical school watching the M701 jet engine cut and thinking about WHY are some technical solutions as they have been built by the engineers 50 years before me. One thing remained in my mind the fuel (kerosine) tube was let inside the combustion chamber meander-like. That solution will heat the kerosine using the heat from inside the combustion chamber. The kerosine is already near vaporized when is mixed with the air so you get a better mixture. The combustion chamber on rocket engines is cooled with fuel (not oxidizer) and then the heated fuel flows into mixing nozzles in the back of the combustion chamber. This is the same manner as you described.

[@Rogue9]

Awesome job. And the sound that thing makes!!

[@adamharith911]

Didnt expect to see you here

[@thomas1055213]

remeber when they did cool shit like this?

[@krang07]

ya, these days everyone`s gravitated towards quad-copters and all the shit you can make em do.

[@amk1108]

yeah. i agree to much quadcop[ter shit. plane are cooler

[@amk1108]

exactly its not even that cool besides spying on yur neighbors with it.

[@kevinbatungbacal]

I agree, I am so sick and tired of seeing quad copters. I want to see airplanes and helicopters for a change. I hope Flitetest sees our comments 😞

[@lontongtepungroti2777]

but.. but quad copters cool too..

[@Xynudu]

Really good episode. But then again, they are all really good videos. A real pity David couldn't stay in the USA. His enthusiasm and knowledge make it very interesting.

[@colepatrick5019]

He needs to be a citizen, why isnt he, he is a part of flitetest that does experiments, plz come back david. :c

[@woutchauvaux6672]

He has to come back i miss him haha

[@jeffk464]

***** "he's not a citizen" Ha, havent you been paying attention its now basically legal to be in the country illegally. :)

[@panzerken]

+99smite So true. What a shame. Send the creative smart white guy back home, but let uneducated non english speaking people in by the thousand. All is lost............

[@iteachvader]

3:45 It sounds so cool when it activates.

[@thatpolishhotdog]

IKR. Damn I wish I could see this thing in real life.

[@iteachvader]

Narwha1Gaming EU Are you following me?

[@thatpolishhotdog]

No... Why do u ask?

[@iteachvader]

Narwha1Gaming EU I feel like I've seen you somewhere else very recently. I recognize your username.

[@thatpolishhotdog]

Ahhhhhhh... Well I guess I am following u

[@BenjaminGottsch]

That is just the coolest sounding plane ever.

[@joesilvestri4925]

I agree

[@psygn0sis]

fake sound!

[@placeholdername4068]

psygn0sis Rubbish.

[@Lunumbrus]

You guys have no idea how much I wanna see more jets and afterburners from you guys. The KSP nerd in me just has to see what you rig up.

[@heyitsclayyy3002]

Lunumbrus same dude

[@heater165]

Saw this video 10 years ago. This has been my best flite test video till date ❤. Very beautiful weather, calm. Twilight and that afterburner colour, Looks so good!. Not to forget the evil tower 😅

[@dominicrichardson5546]

Weirdly the most nostalgic thing for me was hearing David mention "hotwiring" a new tail. I completely forgot that all the hobby/craft channels like TKOR etc used to use nichrome wire to precisely cut foam for projects.

[@ishigamiyu1991]

The old sweet flightest with the old sweet music

[@NiclasHorn]

I miss the Old Flite Test

[@cryptosalmon]

Same

[@texmex9721]

Swede! Swede! Swede! Swede! Swede! Swede!

[@gracklefpv8811]

Me too

[@laludeaka]

Niclas Horn me too man

[@jhoni_48hz95]

yeah me too

[@Nottalottasleep]

Squashed tube for a limiter? So freaking brilliant - to know the elements of the process so thoroughly, to know the processes so well that he can wing it - can't believe that pun just fell out of my mouth - but to be so at ease with the project that David could make a jet fly, yes that's amazing! But to be able to put this knowledge into action - thrust angle, load versus flammability off the wire ( gauges so fine ), it just boggles the mind.

[@henryatkinson1479]

Still my favorite episode of all time, when I finally get around to making an RC Mitsubishi F-1 Ill do this.

[@CuriousKitchen]

That is absolutely awesome. All along I was like "this Vampire will burn in midair". And what a sound!

[@kpopRC]

THIS IS THE COOLEST!

[@Raycefan]

So thankful to have had "THE SWEEDE" and his engineering genius working with y'all back then. Such a great guy and so knowledgeable about such building projects.

[@Cheeseoverdose]

this was the very first flitetest video I ever watched and I have been watching since.

[@TheBlanco951]

After watching your videos for almost two months now, im considering getting back into the rc hobby. Your videos are so much fun to watch!

[@MelindaGreen]

If it provided no substantial thrust, I was dubious about the idea but the sound it makes is perfect, so kudos!

[@regchavez1831]

Melinda Green it's all about the sound it makes. That "sound" makes logic do weird things.

[@Crimsonedge1]

And light does actually have mass.

[@MrCountrycuz]

can we talk about your rates?

[@keenanbartlome8153]

umm actually, light (photons) do not have any mass.

[@MelindaGreen]

Keenan Bartlome Light has no rest mass but mass and energy are equivalent, so photons do have a mass equivalent to their wavelength.

[@greggv8]

Could shield the tail with aluminum flue tape. Instead of having the metal exhaust tube in direct contact with the foam, make it with an air gap and have it so some air can flow through the gap. Then the burner can run longer without melting things.

[@skakpedersen]

Burn, butane baby, burn! What a bunch of clever thinking, behind this project. Well done guys. Thanks for sharing.

[@Pulse589]

You have inspired this newb to get into rc quads! just dropped a few hundred bucks in your store now! God bless and keep on keeping on. I will continue to binge watch your channel.

[@BobAlexander]

Perfect application for my inverted V-tail!

[@toysareforboys1]

Wow, the sound it makes is absolutely amazing!!! :D

[@ejb654]

David Johnson umm actually flaming gas by itself does not produce thrust, the sound is dubbed

[@19leon73]

ejb654 The Thrust is from the EDF.... You did notice the plane flying before the afterburner was lit? The sound is not dubbed... Ignorant buffoons...

[@ejb654]

thrust from an electric fan does not sound like a gas turbine engine, im not ignorant, you're just stupid

[@19leon73]

ejb654 Try it before you call it fake it my last suggestion for you.

[@isyourshitfixed]

Leon the sound is dubbed , look up a Rc edf video and listen,

[@kmiya211]

The sound of the after burner is awesome!

[@furonwarrior]

I love watching these classic Flitetest Videos.

[@michaelrudge9880]

Wow, mother of all inventions, I love it, like the choice of aircraft, when I was in the RAF in the 1950s we had vampires and jet provost aircraft. so it took me back to the best time of my life,,, thank you

[@KevinMillard68]

thats totally awesome man well done

[@BradfordGuy]

If people in Sweden are half as nice as David, I bet it is a wonderful place to live. David, you did a wonderful job figuring all of this out and making it work! It is amazing to watch AND to hear...WOW!

[@flappy7373]

3:45 - that is SO AWESOME!!! You, sir, are an artist and a gentleman!

[@jamesmaseobrown]

This is the best RC channel I've seen.

[@mohammedansari7888]

do not try this at home? where u wanna me to build this awesome thing? in office ? :))

[@GniewnyMedrzec]

You can always build it at your laboratory :P

[@steveofficial4071]

Or at a friends

[@abhishekgourav6144]

Nope in a room filled with dynamite

[@Disinterested1]

where else?

[@breather8758]

@@abhishekgourav6144 Great idea

[@purplechicken86]

This has always been, and will always be my favorite intro and episode.

[@joeys5429]

yeah its called the idiots chanel made by and for

[@purplechicken86]

Joey S lmao what?

[@TheTeufelhunden68]

The flames combined with the Doppler are GREAT!!! Gives me an idea for a project. I love this channel.

[@rcbrosproductions9129]

The AMA Rules state that "No model aircraft shall have a gaseous boost", that means these guys broke the rules #rebels lol

[@corbinpearce7686]

So, there's a lot of rules regarding "model aircraft." However, in this document by the FAA (www.faa.gov/uas/educational_users/media/model_aircraft_spec_rule.pdf) a model aircraft only counts as such if flown within visual line of sight. My point is stick a camera on it, hook it up to a laptop control and fly it far far away :)

[@motoman22atgmail]

The thing about smart people is that they seem like crazy people to dumb people. These guys are genius.

[@harrymeanwell1462]

NO THEYRE CRAZY

[@bassemb]

David is amazing, I love seeing how he set up the whole thing. Great video.

[@veizour]

To this day, one of my all-time favorite episodes

[@BoodleBops]

WHY IS FLITETEST NOT A SHOW?

[@Fixxate]

Because the need to pay money to get on tv, maybe even Netflix. I was half expecting that plane to explode though.

[@HolyGarbage]

BoodleBops It is, you're literarily commenting the flite test show right now...

[@kaib.5708]

RandomSpaceManInSpace A show doesnt need to be on tv, it could just be on twitch and youtube.

[@alnoso]

yeah but a TV show has a budget of a couple million per episode this one has like a couple hundred

[@planesstevee]

@Mike Louw yep so true!

[@zippy3711]

If you constrict the output hole just a little, it will give more thrust.

[@Hellsong89]

But it would collect huge amounts of heat, so i would presume it was like this for reason... and it being foam+heat dont mix well... but that can be engineered around ;) I start to like this idea, though needs bigger fuel container so its not just for 60sec...

[@phildoethedildoe]

This is by far one of the coolest build/rebuild episodes you guy's have done! I fly all kinds of RC planes, blimp's, copters, and such but this one takes the cake!! WELL DONE DAVID!! Stay crazy and Swedish and keep frankensteining aircraft with the two josh's :) :)

[@arnehollstein3651]

You can really see how moved David is. Nearly brought me to tears...

[@prestonwallace7939]

wow sounds realistic

[@nerfinator03]

Its funny how you sed "Even if we are showing you all of its components and how its made do not build it at home" by saying this, in a near future youll have one replica of this stuck on your roof

[@torpedo996]

Or a Concorde version of this.

[@stevo43068]

The sound was AWESOME!

[@zachweibel3716]

some serious ingenuity there. Good job!

[@Frank-il2my]

while others were busy studying in school,i wanted to be john legend

[@yves3560]

Beautiful work !! sounds good too :)

[@wisegamer706]

thats gotta be the coolest thing ive seen in a while

[@michaelknee6362]

That is one of the coolest things that I have seen on youtube!

[@MyWillyboi]

so the coil is like an expansion chamber?? AMAZINGLY WICKED AWESOME

[@TheRocketdrive]

well it serves the same purpose, but it isn't an expansion chamber. By making the butane travel the extra distance and heating it, the butane is given time to go from liquid to gas.

[@HookedOnJonics]

MyWillyboi thought you were AVE for a second.

[@mjpeeved]

HookedOnJonics I thought so too. Shady business.

[@powderslinger5968]

MyWillyboi. No it is a heat exchanger.

[@taevue]

3:44 Goddamn thrust sounds so nice!

[@rodgerhatfield3068]

From one grown up kid to another...great job!!! That’s so awesome

[@LeviTorgerson]

I enjoy watching Flite Test channel. This is the coolest yet. I just love the sound of that Vampire! Come on David, you must go to the next level with this concept. Be safe, but, be a mensch and develop this.

[@ishigamiyu1991]

Wish they would bring back the opening

[@TaubogaCraft]

is this jet sound real? AWESOME!

[@scottmarshall6766]

OUTSTANDING!! Love the sound.

[@mavenhelm]

One of my favorite episodes. Do more like this please!

[@NimN0ms]

Challenge: make an aircraft that can turn into a ball in mid air, stay like that for a while and then turn back into an air craft!

[@EnFuegoDuo]

I don't know why, but the visual of this had me cracking up bad XD!

[@EvenTheDogAgrees]

Start small, do Cobra Commander's helicopter/jetfighter first. ;)

[@stevenshaw9559]

Bring david back!!

[@monasri92]

Epic. And the cinematography was awesome too! :)

[@obese1konobe]

Totally, outstandingly, awesome! Well done David!

[@EvenStarLoveAnanda]

I think you guys should make videos about ALL the things not worth trying so we don't have to replicate failed experiments. Imagine how much money the rest of the world would save! ;0)

[@russellalexanderyim8623]

make a messerschmit 262

[@anonymouswatcher6691]

liked your comment even when i dont know what is it. Can you explain to me? heheeheh

[@fastyh2745]

it was the first ever jet aircraft. made by the Germans in WW2.

That was such a graceful flight. nice job guys

AWESOME!!! i want more of these videos and watch it over and over

[@rubennouta2406]

Does it actually increase speed?

[@Yman83464z]

15% more.

[@Lanzbik]

Ruben Nouta increases the coolness by at least 300%

[@joeys5429]

haaaaaaah

[@neweintleul4757]

Hi Guys: Really cool vampire, and the afterburner. I am almost jealous :) . You have doing extremely well, and congratulations. You use a electric motor powering a fan in the duct, right? so you say you got about 15% more trust with the afterburner, right? Keep up doing your nice projects. Have you studied combustion and aeronautical engineering at all? It can be a little frustratin depending on your teachers, but you should go for it since you already know a lot. Once more cheers !

[@michaelfink64]

Great job, “The Creator” David. The sound of the afterburner was as good as seeing the flame.

[@flyguy_aviation]

Dude David is awesome! I love this plane with his modifications to it!

[@bepsi306]

omg just fly that over a military base lol 😂😂😂

Amazing stuff David! Love the engineering.

[@gallezzo6650]

The most awesome thing I've seen in a long time.

[@kuyanatnatdkrx7]

i would pay them to kamekaze that plane at full speed with 80% butane left

[@njd834]

Ok that will be around $1000.

[@EvenTheDogAgrees]

Wouldn't do much. At the speeds this thing flies, you're very unlikely to puncture, let alone burst the canister.

[@joeholzman1271]
