Jet Assisted Take Off (JATO) RC Plane

[betulakevinii]

RATO not JATO.

[truth2009able]

@betulakevinii

All RATO can also be considered JATO, but the opposite is not true. Rockets are propelled by "jets" of hot gasses. So they still fall under JATO. The jet fuel packs usually considered under JATO, however, are not RATO for obvious reasons.

[Fourteen88SoCal]

lol cool!

[megapot229]

is that plane a kit?

[Andre232323232332323]

ok now thats fucked up

[gatorsoccer01]

how did u do that?

[gatorsoccer01]

how did u do that?

[carmium]

Now that you can make it work, how about seeing the system on a nice Herc or C5?

[Maxvlasov14]

Cool

[wocketman1629]

Why use a BP motor? Use an aerotech e45 or something like that. much smaller. 18mm vs 24 mm. much more power and lighter. Or just say screw that and Use a 300 lb Q motor that we have used with Team Numb?

[Marzmany]

@MrCanada967

The motor is on. Otherwise it wouldn't fly after the launch....This was from a senior project for the DoD. They are now deploying a system based on these prototypes in "hostile" territories. They air drop them in various locations in advance, and then when they need mobile eyes and ears rapidly, they launch one of these out of their boxes. Rant by middle age man....FAIL

[elgringogms]

SPIRIT from GRAT PLANES, a great one

[pdude40]

jatos were used in mythbusters on compact on compact jatos are really fore missles thats why there not used on 747s

[dantiri]

damn slo mo vids

[stoopidoooo]

now for an rc c-130h....

[spektrum33]

O.M.G that must be at least 10 feet {+_+}

[mitchellyoungable]

thats so legit

[grupa2009]

its actually RATO rocket assisted takeoff

[Marzmany]

@grupa2009 RATO is a type of JATO. Rockets are propelled by jets of hot gas. I think the sub category of RATO is unnecessary. So long as you are using a secondary lift device that uses a jet of fluid (air is a fluid, fyi), it is JATO.

[gabrybilly]

is very dangerous! because the engine could explode with all that pressure

[jfjenofhrenon]

imagine JATO on commercial passenger jets... "come on children wave goodbye to granny" then WHOOOOOOOOOSH - she's gone in a cloud of smoke" :-)

[aldudio]

sick that is sick

[DrJamesWilliamson]

The slow-mo sucks.

[Marzmany]

@DrJamesWilliamson You can watch it in full speed if you took the time to find the video in my gallery.

[mandunya]

What is a JATO

[dexdog2451]

that is amazing

[AirShowFan22]

what rockets are those

[fuzzypaws17]

great idea !

[ed563]

dont put it in slow motion

[02kellt1]

well done for getting it to work it looks gd

[megatron20000]

0:28 and lift off!! xD

[Marauder0090]

worked good..those high altitude wings held up very well no real bending or flapping, good power ratio...enough for a controlled launch and to get some altitude under those wings.

[SaintGnarly]

So what part is being controlled by a radio? Seems to me the tether is handling the steering and the throttle is wfo. How is this an RC car?

[mattq41]

What do u mean car? thats obviously an aircraft!!

[jdamion]

THUMBS UP!

[m14closerangeSniper]

we are not high so put it on normal speed!

[Marzmany]

First of all, most youtubers are high. Secondly, it's already up in full speed. It's noted in the description, in the video annotations, and listed in the video responses. =)

[Ryldj]

weird coincidence, i am high. Also what is that JATO , is it a scaled down version of a real life one used on passenger jets?

[mattq41]

passenger jets dont use JATOs.

[Marzmany]

But they should!

[darklazer52]

you can say that agen

[TopGun904]

@Marzmany It cuts takeoff time in half!

[airpower123]

@Marzmany can you tell me where i can purchase these rockets from?

[Marzmany]

@airpower123 You can get the rocket motors from any hobby shop. They are size D motors. Just be careful. Never disassemble the motors or use them in a way not intended by the manufacturer (i.e. how I used them).

[airpower123]

@Marzmany can u give me some links to a site? beucase i'm interested in purchasing some for a project i want try. also would u have any idea on thrust giving from these engines?

[Marzmany]

@airpower123 Hobby People....ummm, try googling "Rocket Motor". The shopping section of google has many links. The thrust varies from manufacturer to manufacturer. They usually provide a time varying graph for you of the thrust force over the half second to a second of burn time. For this project, we used 6 D motors. The peak thrust was 30lbs (I think). You'll have to do some calculations of your own. It has been some years since I did this.

[airpower123]

@Marzmany as i remember my high school physics the thrust of a rocket is given by two factors mass ejected by the fuel, and the velocity at which it is ejected.

So of a engine the mass ejected for certain engine should remain constant, and as the fuel is'nt going to change mid flight the explosive energy of the fuel should also remain constant. so the thrust should also remain constant, but the as mass is being ejected the system will get lighter and acceleration should increase expontionally

[Marzmany]

@airpower123 Not quite. The thrust curve can be all over place. It usually steadily increases over time. Peaks. Then rapidly declines, but it doesn't have to. It can double peak among other things... One thing is for sure though, it is not constant. The temperature and geometry of the propellant changes as it burns. This causes changes in the pressure inside the rocket. Although a nice even burn with constant thrust is desired from rockets, it is hardly ever achieved. tinyurl_com/23klya9

[airpower123]

@Marzmany hmmm really? wow i did'nt know that. my teacher told me only the newest american rockets like the space shuttle has the technology change its thrust mid flight. and all other rockets have a constant thrust throughout, they burn for example 1 ton of fuel per second. if u reduce that rate the engine will malfunction but the nasa people have worked out a way to do that.

[airpower123]

@Marzmany also he said that multi staged rockets are need for human space flight, beucase as the thrust remains constant, the rocket is loosing a ton off its weight every second. so the accerlation will countine to increase. so to prevent G force exceeding too high, they need to use a lower thrust engine i.e the second stage. let me know if i'm, i'm interested.

and thanx for your help, i found quiet a few sites. i did'nt know rockets were avaible to the public.

[hotblume]

@mattq41 actual theirs a city in Bolivia were the altitude is so high they have to use JATOs i know this for a fact because ive visited it.

[marmaloon]

@mattq41 more's the pity [/disappointed]

[m14closerangeSniper]

oh sorry i removed the annotations

second of all im stoned on coke so i need the fast speed version!

[Blakhawk1703]

@Marzmany i aint gonna lie. im pretty high myself lol still neat video tho.

[Delta10666]

Cool!

[TwoEyeCyclops]

SICK DUDE!

[xcruzrr6]

F%#$ing bad ass

[FunkyRoverz]

Looks like San Diego in the background. Mission Bay by Seaworld ?

[Marzmany]

Good guess =)

[azza0193]

yeah, it is, i was there last year and stopped by that field, got pictures

[jnjoblon]

Wow, aced it first try... that's pretty damn impressive.

Cool video

[saberdryver]

RATO not JATO dummy cool vid though

[johndela1]

"JATO is an acronym for Jet-fuel Assisted Take Off. The term is used interchangeably with the (more specific) term RATO, for Rocket-Assisted Take Off."

this quote is from wikipedia

[spi898]

No Its Just Jet Assisted Take Off

[johndela1]

spi,

I think you are missing my point, I quoted wikipedia to show that JATO and RATO are often used interchangeable. You don't normally hear people saying something like 'this is RATO no JATO', it is accurate and common to say this is JATO.

After all a rocket is a jet

[spi898]

no Im Talking About JATO Its Not Jet-fuel Assisted Take Off Its Just Jet Assisted Takeoff

[peepeevagi]

He's reffering to how the army calls it JATO.

Like the oooold rocket bottles.

[sailindude1221]

no its jato

[fiddleup]

No Offence taken :) I think your plane is amazing! I have done "regular" model rocketry over the years,  but this is just fab!! Well Done.

[fiddleup]

Sorry, my mistake,.....I had no idea, I just came across the slowed down video and did'nt know there was another one..... :)

[Marzmany]

I didn't mean to be rude but if you look through the comments, this question is asked every few days. And then there are those that want to see the regular speed video because they think I photoshoped this one. =)

[fiddleup]

Real time, please ??

[Marzmany]

For the love of god people, the real time video is posted. It's one of the video replies and in my list of videos. You could just download the video and slow it down yourself if you wanted.

[lonstar70]

Well ya know, you might want to add that as an annotation on this video, because a lot of people, myself included, dont pay attention to video responses. Just a suggestion...

[humanidt]

really, what is the chance that you will get a perfectly stabalized launch the first time. and that is a foam plane, prob about 2-3 pounds. the rocket looks like it can lift 5, it wouldnt lift off that slowly, even in real time

[doubleup5150]

would love to see real time.

[thecreatornator]

I like the big plume of smoke, with the plane bursting out of it magnifacently :)

[WEESTRAWZ]

HAHA! That is soo cool!

[DARIO8417]

Is brilliant! O_-

[oceanchaser]

very creative i like it very much . i guess the more rockets the higher you can get it im a right.

[brettwrb]

The A in JATO stands for assisted, which means that it isn't your only means of power. JATO FAIL

[Marzmany]

It has an electric motor. COMMENT FAIL.

[brettwrb]

Oops, I see it now. FAIL RETRACTED!

[LTF85199]

The J in JATO stands for Jet asisted, which means it is a some kind of air Jet propelled, but this is a rocket propelled take off. Should be RATO, so JATO FAIL. :)

[Marzmany]

RATO is a type of JATO. JATO is a blanket term that covers most propellant assisted take offs. A jet is a stream of gas. What comes out of the back of a rocket? Gas. Whether it is a liquid, solid, or hybrid rocket, the propellant must turn into gas in order to increase in pressure and volume and propel the rocket. So RATO and JATO both unFAIL.

[LTF85199]

Oops, I knew you are going to say that. FAIL RETRACTED! :)

[ljsavmech]

can you try it with some on borad vids. that was hot

[ehsanaman222]

LOL...That was soooo cool!!

[Frederick002]

ooo largo

[huntindan24]

Where did you get the rockets? i might make something like this... or at least try.

[davidsimsjr55]

Yea and burn your ass up...lol

[huntindan24]

at least i'll have fun while doing it. haha

[Marzmany]

Any hobby store will have rocket motors.

[Iceman5164]

At 0:45 I think it stalled, not sure though

[Laevi1337]

sure did

[Marzmany]

And then at 0:50, the pilot has recovered and flies off.

[greatplanesman]

Yeah, seriously guys. If you're going to do a JATO on a plane, then at least put a full speed video up.

[Marzmany]

There is a full speed video. Click and ye shall find it.

[sk8EJECT]

to be honest i would really like to see it without the slow motion

[sdably]

i agree

[myrransf]

That was cool.

[maglight117]

now that was FUCKIN AWSOME

[Flyawaywithme11]

not a bad take-off

[joe735]

looks like a rocket to me, not a jet

[dkthemovie]

read the description -.-

[Hawkeye0918]

Isn't this technically RATO?

[slacker3442]

cool

[kjetil297]

cool ake off

[fmeriqui]

awsome

[TheRealBoof]

I dont think thats a real JATO D:

JATOs can only be bought from the millitary, and u need a permit, i saw it on mythbusters :D

[forrest225]

They are also as big as the rc plane ;)

[TheRealBoof]

lol yeah xD

[ddmo2]

and they make 1,000 pounds of thrust....

[mouselg]

JATO is an acronym that can be used for every rocket that assists takeoff`s.You might refer to JATO`s as those big rockets used for the airplanes on a carrier.

[keenyuen9]

air pollution.....

[Marzmany]

liberals....ever wonder how much "pollution" you create when you burn an entire gallon on gasoline every morning on your commute to work. Besides, I don't think of it as "polluting." I'm feeding the plants CO2.

[Rexpilot0990]

Let's not stereotype here. I'm liberal, and I see not one bit of problem with having a liberal amount of fun :D

[Marzmany]

I was faking it myself. Go Obama and RC JATOS!

[Rexpilot0990]

I'm more than confused, but oh well.

Agreed.

[Scott1821]

comment pollution

[9W2XFC]

freekin kool!

[kori229]

lol

[Nitroboss2007]

pay attention at the stall...

[v16050118130114]

Don't know if you're aware of this, or not, but Aerotech makes reloadable long-duration motors designed especially for rocket gliders, in 24mm ("D"-sized) and 38mm sizes.

[bblokhed]

needs a second stage and or longer burn

[xReventonx]

thats sooo cool

[RF3seeker]

I think thats a gentle lady. I built one, long ago. Never put power or steer control to it, but it sure did glide well being hand thrown.

[PRJohnnyT]

wow I love gliders , but prefere if they have a little electric engine just for take of, than rockets ^^ but still really coool nice job!!

[DSB1234567890]

Nice system, would be good for gliders if it didn't make too much drag / weight. The one problem is that the plane is very nose up at the time the rocket turns off, that could make u stall.

[navajo1806]

i dont need jato to take off like these.

[taofledermaus]

Very good camera work!

[jakeharvey]

Yes, but the term JATO is used interchangeably with RATO. They're the same thing.

[Flight1142]

Where can I get the rockets that you are using in your nice airplane? Thank you.

[1944george]

One slow speed, one normal speed

[wrjstuka]

you maka me laff! sorry i guess thats why jet pilots shouldnt do to much strawberry haze! i was half in the bag when i wrote first pt was in responce to people always havin a pissin match about everything on utube when i got it it on my email i was laffin thanks for reply stay kool aj mycyver

[wrjstuka]

oh huh like whats da point? come on its just pissin cool fun to do i say thanks for postin marz me i say wicked cool my hat goes off to you and the crew well executed corect cof gravity after the jato fizzed out you rock dude !i tried it with agulliows mustang not quite the fantastic results you had all in all well done we are gonna do this with a hang glider you in? thanks aj mycyver over and out

[xilix]

I swear, you're trying to say something. I think that over the course of maybe a year, I could study this post and figure it out.

[jlukevand]

Awsome! will def make my own for my glider

[ivangutowski]

nicley angled jets

[fetborsted]

Why would you bother? Just throw the thing!

[skyseeker901]

but this is so much more fun!

[darksk8er91]

why dont you grow sum gonads!!

[fetborsted]

Jesus Christ. Another pissing contest. Here we go... Why don't you learn correct spelling, punctuation and grammar! You went to all the trouble of retrospectively sledging me over an opinion the I expressed two weeks ago?! Sometimes I think I am wasting my time here. At least skyseeker 901 wasn't an asshole about it. Jeez.

[darksk8er91]

whos cares about spelling, its youtube ffs..and way to not take it personaly

[Ricmcspeedy987]

yeh. jato stands for Jet Assisted Take Off, but they are rocket motors.

[soarnluck]

not much for soaring ,,whats the point?

[RCReview]

Fun....

[airplaneguy2]

NO WAY, THATS INSANE!

[kartracer93]

just like an hercules army freight plane.

I saw an hercules do that with 4 rockets on either sides that wuz crazy

[marker106]

lemme guess

blue angels-fat albert???

[kartracer93]

yeah (H)

[JIMBOJON75]

wow ,much energy for low speed

[sjvietboy408]

Should have shown the plane take off in normal speed.

[knifeedge63]

i agree!

[hdinfo1]

How do I find a glider that flys that slow?

[drsheikhjunior]

you'll stall if you flew in that speed

[drsheikhjunior]

and I mean if it flew as if it was in fast the slow motion in real time...not in the real speed ;D

[Stumpjumper14]

How much does it cost to get a glider with servos controller and everything?

[Thumanator]

That glider is called the Aspire EP from Hangar 9. It's an RTF and it costs $239.99... so good luck trying to get one.

[yoda9148]

thats the best rc rocket footage iv'e seen on you tube

[RCpipercub1]

where can i buy 1

[crzygutrsnobrdr]

on a sailplane lol

[superstl]

RATO is the more specific term, but the correct military terminology is still JATO. Ask an Air Force/Navy pilot. They use JATO bottles. No offense. RATO is not wrong either. It's just more specific.

[brunocortese]

It's RATO (Rocket Assisted Take Off), not JATO.

[blackbombs]

JET Assisted

[gertnood]

No, rocket assisted. RATO. JATO is a misnomer.

I wish normal speed footage was shown here, slow mo only is kinda disappointing.

[CaliforniaDeaming]

My thoughts exactly! I also would have like to have seen the plane's landing.

[J04TM0N]

i want to see fast-mo

[J04TM0N]

i want to see fast-mo

[1badmofo90stang]

show it again in faster speed. what a dork who wants to see the slo mo

[Marzmany]

your momma's a dork. it's already posted at normally speed. you're just too lazy to find it.

[wallaguest1]

you could play it at real time too, not just at slow motion, shit.

[TheHanf]

looks cool !!!!

it seems like its a nomal tow start with faked rockets. there are so few pictures that it wouldnt be a problem to fake each picture.

i dont say it IS,
