R/C Twin Rotor Tractor Puller

[gOneferalinc]

Fucking ledgendary!!!!!!! Love it!!!

[westwing23]

now go full throttle bud

[SuperBmxbadass]

dam thats got more power than a honda

[Tinytacohead]

Twin-rotor RC = awesome!! ..but good gawd, $900+ in "one" engine?!!  You sir have too much money, haha. :-)

[douro20]

@Tinytacohead

Yep...US$450 each. And not to mention the cost of parts and custom machining a new output shaft.

[Tinytacohead]

@douro20 Can I borrow a few bucks? I've got a full size twin-turbo that likes to shoot money out the exhaust. :D Back on-topic, got pics of this sucker uploaded anywhere? Would love to get a better look @ it.

[driftking9293]

sound like a big machine

[14omega28ok]

Sounds tougher then any Honda I've ever heard

[simcaP60fan]

sounds like a v8 on steroids xD or LOTS of nitro

[lg20tmlg]

nice pull

[TheMrSuperBlitzer]

hes not even revving it hard and the tires r already balloning lol

[TheArtmamon]

движок роторный походу

[martiniceify]

i that a rotary motor??

[fucker666477]

@martiniceify yes, os engines manufactures them

[JuanPapaNicolao]

sounds like the real thing only smaller

[Josh1223334444]

Who needs air filters? Lets run without!

[soverato3]

0:15 epic Fail airfilter fell of hahaha

[Paintballboy54]

this sound is bonerific!

[Paintballboy54]

That sound makes me hard =)

[planedestroyer94]

tires get bigger thats cool

[JohnnyGTR34]

Sounds like a really p*ssed off bee :D

[czolgista999]

Damn, it sounds nice !

[Ronnye17]

goodbye filters :D

[mountainboundwbd]

notice when he hits the tthrottle the wheels inflate more

[zbadass650]

@mountainboundwbd its from centrifugul force

[nizmo3fiddyz]

omg is that a drive shaft?! this thing is awesome!

[steemy2]

you lost the airfilters lol :)

[Mrcoolaidman72]

WOW. I think I speek for everybody here.

[MegaJames1967]

Do You Build These Tractors Are Do You Know How Does.It Looks Nice Thanks

[MegaJames1967]

Do You Build This Tractors.Are Do You Know How Does.That Tractor Looks And Sounds Good.I Would Like To Have One.Thanks

[yuhcgte]

DAMN!!! I WANT THAT

[JaddahRoberts]

hmmbin so einsam heute wäre echt klasse falls sich jemand finden würde der mit mir schreiben will

[123456789ftp]

sounded cool az , nice

[boomstickkid]

SICK look at the wheels when he gives it gas

[TrikeLovin]

awsome......I just noticed both of the air filters shot off....lol

[TrikeLovin]

It sounds wicked fast....

[spankyb16]

its a real rotor engine ?

just small

[jack4373]

sounded beefy

[kasea150jim]

@jasonhausmann those were the air cleaners the battery pack ont the front jumping when he hits the throttle is the glow plug warmer

[BimboDFW]

lol.. Its the air filters falling off not the glow starter

[Superdude688]

lol @ the tires and things falling off

[FourSidedPiston]

Air filters.. no big deal.

[xconrad455]

i like how the tires expanded whn he revved it

[bjornpauw]

cous originaly de os wankel is for a plane and its get a lot of cooling from de prop and flying through the air. So could i put my wankel on my car without cooling, cous it would be a lot easeyer :D

[bjornpauw]

isn't the cooling no problem? How do you cool them?? I'm making a rotary engine on a rc car (its only one though :P) and for the cooling im putting a computer fan on it.... when its finished ill put a video on youtube

[rbtinnsmith]

that thing has a great exhaust note!

[jasonbc69]

air filters dont stay on long.

[SirTaylorRyan]

@jasonbc69 Those are jumpers for the glow plugs.

[douro20]

@jasonbc69

Yeah, and I know what can happen without them- a German rotary powered mower failed marketing attempts in Australia when it was found that its lack of an air filter caused fine pumice dust from local mining to eat away at the rotor side plates.

[medoseedo11]

mini bridgeport!!!! hahahahaha

[Helliart]

Hi you said in earlier comments you have cad drawings to join two of these O.S motors. Do you still have them? Any chance of getting a copy or link to them? Thanks

[MegaStupididiot]

did anyone notice that hes using a stick controler and not a pistil

[jedimaster93]

to be honest i prefer stick .:)

[MegaStupididiot]

ya its alot easyer

[racarb]

don't you hate it when you forget to zip tie your aircleaners on.

[mynameis63]

lol..that's what I thought too as it fell off..

[jsdhesmith5]

I had no idea that they were using these motors for RC application, how bad is that. The wnkel/rotory motor is so cool, what a genius design.

[watchforfinger]

the tires look like a real dragster when they enlarge like that ...cool

[lovetts23]

what type of motor is it and i know its a rotary is it a wankel design and where can you get them from is it ported

[majidnaeem]

wow

bad ass...

THONG:P

[markmn125]

that is bad ASS! i love how pissed off rotary motors sound

[gizmo98550]

little bastard sounds crazy!!! lol. and check them tires..

[javy0820]

lol the tires are getting bigger when he revs it

[BrickMuffin]

check out real life drag cars, same thing.

[darkeyce02]

yea they just get taller and less wide from the rotational force

[ShadowtheRotarygod]

GIMME!

[zajdabneeg]

holly comoly

[FTFDan79]

uhh did those tires gett bigger when he reved?

[bigdog813]

yup that is normal like on motor cycles

[utookmynames]

or ppl cud just read a book before sayin shit they dont know... either way who cares its a bad ass car!

[Tubeboy732]

Sounds Just Like the big boys just with a higher pitch

[yontopapa]

Understand Spanish? ¡See: Motor Rotativo Yonto 1, 2 and 3!

[SWATsqad]

Look at the wheels! they expand from the torque.. insane

^^

[angusandleigh]

It's actually the g-force generated by the wheels RPM, not torque.

[SWATsqad]

smartass. : ) i know.. actually...

[280zx2by2]

centrifugal force not g-force

[kochj0713]

no need for that that airfilter I recon?

[crashhit]

sick!

[sikkarnt200sx]

das mad as cuz

[matt1746]

That looks awesome when the tires stretch out from centrifugal force.

[bnumber8]

centrifugal force does not exist. cool to see the stretch though

[antonyaiken]

yes, another human being with the same sence of physics as me...

[bnumber8]

rock on anton. fight the ignorance : ). i love how i get thumbs down for politely refuting an absolutely untrue statement. oh well

[cruddbucket]

Wtf are you on? explain your reasoning :)

Very cool video, twin rotor PP, love that distinct sound!

[antonyaiken]

centrifugal force is a fictional force. a rotating mass has a rotational force (centripetal) that keeps the mass in motion. and a static force holding the mass inwards from the centre. so if you spin a ball on a string there is a rotational force (you spinning around) and a static force (your arm holding onto the string) if you let go of the string it doesnt fly out from the centre as centifugal force would state. but carries on in an arc from its origonal trajectory. thats is centripetal.

[djw117]

sounds like you know your shit, but i think people are just refering to it as centrifugal force not knowing the science behind it.

[olib110]

god thats got to be a fave just coz of that great sound lol

[lawsamb946]

even a scale rotary sounds like a real one super fnnn cool mate love it

[triz250rtecatedude]

do you have any idea where he got the parts for this or kan u get kits??

[AlchemistHawk]

this kinda stuff is all custom made

[triz250rtecatedude]

yes but you can buy the engines, i know they are not custom made

[AlchemistHawk]

yes of course. but its an expensive hobby none the less ^^

[BMW20B]

You can buy the engines from any hobby shop that sells OS Engines.

[MegaJames1967]

@BMW20B

Do You Build Tractors Like This.Are Do Know How Does.It Looks Nice Thanks

[120luiz]

@BMW20B

all OS Engines are rotary ?

[RCPhilN]

@120luiz no. they have 2 stroke, 4 stroke and rotary engines.

[120luiz]

@RCPhilN what engine do you used?

[RCPhilN]

@120luiz I use only electric motors.

[dudeweresmycarlol]

@RCPhilN eletrics for pussys that dont know how to tune em

[RCPhilN]

@dudeweresmycarlol and you don't know the power of Electric Motors.

[mageac]

@dudeweresmycarlol a good electric is on par with any nitro....

[Cchange4us]

F$#*@!

[goldeneye4564]

i would have laughed if a bug or fly went into the carb..

[lazzer408]

Slow it down in a wave editor and it sounds just like a peripheral ported 13b. haha

[12valvepower1]

two rotor

[maqueavelico1]

that a twin rotor or two engines?

[BMW20B]

2 Single Rotor OS Engines, joined.

[tomashcu60]

wow that is cool!

[aircannonmaster]

what engines r u runin

[rx7dren]

i wonder if you can make a quad rotor and TT it with about 2bhp

[hondasforlunch]

yo son you the man son i shit!man props!fuck hondas! lol

[mathewec]

That is what every RC should sound like IMO.

[bjornpauw]

how do you put those two wankels together? sothat it runs as one?

[kwismical]

where did you get it man, i want one.

[damskool]

i want some sexy subscribers!

[venommotor123]

rc controlers would work too and they would just look better than that flat one there

[racermix]

air filtre fell off!!!

[DarcvexiS]

HAHAHA...I got a kick out of that too...they just vibrated off... XD

[12valvepower1]

sachs motors

[toolboy4]

sounds kinda like a air rachet

[Rotaryfatboy]

A teeny weeny little rotary making that noise? Sounds like a baby 787B!

[hrspwrprofiles]

Horsepower Profiles. Com

Brag A Little

[ComradeKalashnikov47]

holy shit that sounds bad

[thefirestorm10t]

Awsome sound!!

[Pleasenoshit]

12valvepower1 thats bullshit it's just centrifugal force on thin rubber

[kinghaul95]

Both of you are right. it doesn't do it for 'the right gear range' but is designed to give it a larger radius resulting in higher top speed. just watch top fuel dragsters. its like adding another gear.

[bucko1s]

your prettymuch right about the dragsters but with this car its just the tires stretching from centrifugal force not much thought goes in to $5 tires

[elitetux]

Heh..yeah..those OS Wankle style engines are designed for planes so they need good air flow or they have a short running period on the ground.

[tubacoupe]

how they keep running wer da spark come from

[shadowhunter45s]

they use glow plugs like in deisel trucks just real small ones

[12valvepower1]

13b pulling engine. mmmm

is this a os gruppner

[crywolfe210]

one of the air filters fall off at 0:15!!

[12valvepower1]

they both fall off

[vmodder]

look at the tyers when he revs it, haha :)

[12valvepower1]

as the engine comes up on the pipe.. the tires alter size to keep it in the right "gear" range..

[30GB]

i wonder how it gets cooled?

[12valvepower1]

air probably. air cooled like a bike engine or a vw.. or maybe no cooling.. only runs a short time.. then is shut back off.

[ballsthatclank]

Damn, those rotary engines sound mean.

[dragman2007]

hello i think that is great would like to know how much too build exactly like that or do you build them?

[DeCoster11]

you are a rich man. good game mister

[farmerman122065]

sort of good mostley boring

[lululaserpiente]

what fuel type it's it?

[BMW20B]

Nitro

[soyfeilz]

what?!

nitro?!

lol

and the engine compression 8:1 or 10:1 or 12:1 to prevent the detonation?

[spacecadetzack]

where can you get wankels that small?

[BMW20B]

Any local model shop which sells OS motors.

[spacecadetzack]

hobbytown probably?

[frozenkiwi1234]

wtf fell off it?

[wirelesscps]

it was i of the two air fliters

[jonesryancr]

lol, look at the tyres

[liambowers666]

lol, the filters flew off. attaching a turbo would blow the engine, remember you cant scale down the explosions going on inside the engine

[tim5656]

how did you connect the engines?? i thought there were sealed at 1 end becuse there aroplane engines

[tim5656]

look at all the wasted exuast!!!! you need a mini turbo for it!!! im dead serious you have to get 1 made!!

[zgoldmen]

the tires expand sooo much when he revs the engine

[lothar2048]

1) This is normaly an aiplane engine, so filter are just adapted to it.

2) This is the O.S 49 TYPE II Wankel Rotary Engine and i can provide this engine to anyone for only for 279 € each out of the box, including the muffler...

3) The performance resides in coupling the engines, that is not easy at all till they must turn at same speed mandatory !!!

[kawakrus]

Omg! what a fucking sound! Awesome!!!!!

[DETPower]

where can i get one of these engines? Or where can i find info on making one? thanks...

[30GB]

lol that thing is so wicked the filter falls off

[xxftwismymottoxx]

Awesome.. still sounds like a rotary too! What does that thing rev to?

[BMW20B]

Bout 20,000RPM

[xxftwismymottoxx]

Damn.. that little thing is wicked.. should make it a lil longer and put a 4 rotor on it. :)

[Justinrx8]

bet that little fucker can haul some ass

[darrinjeffrieskilla]

where do you get one of these engines thats nice when the filters come off that thing gets nuts, sick little engine, must have some ponies.

[macbeth2354]

lol look at the tyres as he revs up the engines :))

[teamdavid13]

why the filter is coming out ?

[jacking99]

madonna ke spettacolo!!

[lilbeast1313]

damn

[Avalanche1530]

they pure:P

they sounds amazing

[BikerTrashWolf]

WOW that is wild, I never knew there where RC rotaries.

[andrewsvids]

y do the tires get big when he revvs it?

[motocross150]

centrafugal force iv spelt it worng

[Davidstadelman]

WHAT KIND OF ENGIN E

\

[laina423]

the throttle response is crazy

[myrx2]

yeah im tryin 2 put 1 of these engines in my rc car aswell but havin trouble with the drive line and workin out how 2 set it up.. any tips????

[Avalanche1530]

i have pics of 2 different rc cars that were extremely modded to wankel/ rotary engines

if u want to see them feel free to message me

and by the way there not my car :P i wish thouhg:P

[toddizdabest]

shit me its got tourq

[ScotchRB30DET]

who the hell makes rotaries that little?!

[RFOAT]

OS engine manufacturer....

Wow-i'm blown away-really-amazing-wow.

What can I say-wow, amazing!
