The wankel engine with moving rotor at backplate.

[sergiomarchena]

thanks for this video ,cool engine

[thegreatcb7]

is this the actual size?! holy shit that thing is small and theres only one of these? of several?....

[79chab]

hello, connexion perfecte whis my research,I looking for the manufacturer of engine vankel to 20 cc at 50 cc thank you very munch best regards chabrut@wanadoo.fr

[hiideruhiro]

@hobo4lifeskater Not necessarily better or worse. They have their own traits which differ from conventional reciprocating engines (piston engines) but the ultimate goal is the same. Some might prefer a piston engine more than a rotary and some vice versa. It all depends what you plan to use it for. I daily drive my RX7 even through the winter snow. Reliability isn't an issue and if someone says otherwise, it's their fault for not caring for their engine ;)

[douro20]

This is an OS/Graupner .30 Wankel nitro aircraft engine. It is the only engine of its type in production.

[Taydrum]

so cute!

[ShadowGKCP]

wanker engine...

[songer885]

How fast does the wankel engine wank?

[1bengrubb]

It looks like the intake and exhaust are totally symetrical. I bet if you put the carb on the other side it would work just as well! I think in this little demo you are spinning it backwards...I tried to take mine apart but those Germans used a ton of lock tight and I didn't want to destroyit. Hey make a glass back for it so you can run it and still see!

[kdc43]

They had this in the 1970s. Whatever happened to the wankels, they were supposed to be better than the pistons, so why we have piston engines and not wankels in 2010?????

[littlemimus]

@kdc43 because mazda had some problems that they pretty much fixed now. and people dont know how to take care of them so they still think they are unreliable.

[Alex98098098]

@kdc43 fuel efficiency and pollution. many cars still use them though.

[19throwback89]

isnt that like a really small Rotary Engine?

[KentGuitarman]

Is it really that small?

[Snake22789]

@KentGuitarman nononono, thats a working scale model bro

[KentGuitarman]

Woah. So small.

[shredthenarbro99]

hehe wankel

[kiwibob72]

Do they run apex seals on the rotor corners?

Secondly, how reliable are they compared to a normal OS 2 stroke Nitro motor??

[SwissBiancoArt]

how much does this engine cost

[iceman86694]

OMG i love it... Pls post more vid with that engine pls!!!

[983211b]

where did you get that motor i want one lol

[Gin132456]

i will buy one of these just to hang from my keychain when i get my FC :D

[hydrobot2003]

it will make one hell of a vibration!

[Mechanicboy]

@hydrobot2003 Wrong answer, the wankel engine are well balanced with contra weight, do not make much vibration as a piston engine, The vibration feel near as a electric motmr.

[QBMan]

@Mechanicboy it will...up and down but your right its not as much as a piston engine. And you geht much more power out of less capacity... Only problem is the tightness, but well therefor you dont have that much wear :) I like it, would like to have one in my car :>

[buggar4466]

@Mechanicboy They are no more balanced than a piston engine. They need counter weights to balance the rotor and therefore are only as balanced as the builder is at balancing it. They are not a well balanced motor. Piston motors such as I6's and opposing engines are all perfectly balanced since they mathematically counter themselves internally. As long as the internal parts weigh the same they are balanced perfectly. That is why the I6 is the smoothest engine at idle or 8k.

[Chevymonster203]

@buggar4466 Wrong the smoothest motor is a boxer motor because the opposing piston cancels out the vibration from the the other. Subura boxer 4's are more balanced than a straight six. And wankel rotary engines are very balanced do to the rotational force and not the reciprocating vibrations caused by a piston engine. Try putting your hand on top of a rotary and you will feel just a slight vibration.

[buggar4466]

@Mechanicboy They are no more balanced than a piston engine. They need counter weights to balance the rotor and therefore are only as balanced as the builder is at balancing it. They are not a well balanced motor. Piston motors such as I6's and opposing engines are all perfectly balanced since they mathematically counter themselves internally. As long as the internal parts weigh the same they are balanced perfectly. I6, F6, F4, F2 are the most balanced angines not needing counter weights.

[Chevymonster203]

@buggar4466 And due to no reciprocating mass they don't need counterweights as a piston engine. The rotors themselves move in a eccentric rotation allowing no mass to sit in one place at any time. Where as a piston engine will have massive inertial load due to the piston always moving upwards or downwards like on the exhaust stroke. The transition from up to down and down to up causes great tencile strees on the connecting rods and crank journals. This is all coming from a v8 lover.

[hydrobot2003]

@Mechanicboy - ok, but you rpobably won't get much power output on that.

[Mxracer6y]

@hydrobot2003 its actually the complete oposite... rotaries produce much less of a vibration

[ooswamaghan]

No - the Wankel is completely vibration free.

[IamScott351W]

@hydrobot2003 Do you know ANYTHING about cars, engines, mechanics, LIFE? WTF!

[hydrobot2003]

@IamScott351W - yes I do. I know your wife runs a 10 horsepower vibrator up your arse! You Monkfish looking dork! NOW WTF ARSE HOLE!!!

[ronmann606]

Do you know of any larger rotary engines I can buy? I'm looking for one around 10hp peak

[1PARADOXXX]

Where can i get one?! its so cute

[iDan245]

OMG is tht engine for a RC???? THT WOULD BE AWESOME!! A LITTLE RX8 RC!!!

[PierMou]

Hallo! Were can I buy a model like your?

Is it on sell?

[danrichards23]

HA! im gonna get a model rx-7 with a real wankel!

[form109]

What Kind of Fuel does it Burn?

[fairyheli2]

@form109 coal

[form109]

@fairyheli2 Coal?....thats Irrelevant.

[sti4lifer]

dont blow an apex seal lol

[terribleoneprimopro]

ARE YOU FUCKING SERIOUS?!

That seals the deal. I'm getting into rc cars. I'll build a replica of my own drift fc in micro format. Does it spit fire hardcore?! OOOOOOOOOOOO! That's so fucking cool!

[jamzie89]

ur spinning it the wrong way haha

[fireninjawolf]

where Can i get one of these?

[vitaliyr1]

What do you use it for? Like RC car or airplane?

[vitaliyr1]

How many cc's?

[Mechanicboy]

The volume are 4.9 cc or 0.30 CID.

[naturalyshocked]

awesome, i wonder if i could mount this on my 1/7 scale RC car.

it has 4.6 or .28CI engine.

how are the mounted, i don't see the convetional mounting points.

[Reverseflush]

@Mechanicboy

Interesting engine but will it blend?

PS..Will you try heroin in your time?

[wilsonhill12]

@Mechanicboy uhhmm.. the displacement of a rotary engine changes.. so its not 4.9cc..........

[Rage71000]

654x2 cc (13B) 2 Rotor

654x3 cc (20B) 3 Rotor

[VladBlok28]

that would make an awesome keychain

[machetero1]

i had a rotary keychain, the rotor broke off :(

[RCPhilN]

does it run?

[Mechanicboy]

Yes, se more of my movies in my movie archive..

[mysticsailor1983]

O.S. Engines makes them

[Shazee083]

were you find this motor the rotors motor

[PorcupinePower]

would it fit into a kit, or do u have to make a custom chassis for it?

[JDMforever11]

is this an rc motor?

[Mechanicboy]

Yes.

[JDMforever11]

wow. i thought they were only on mazdas lol.

[AfghanKnight007]

where do u get one of these please?

[Mechanicboy]

Hobbyshop are selling the engine.

[cable71111]

@Mechanicboy this is for RC car ??

[dingo27mobile]

can this run only with one "rotor" ? not like classic gasoline engine with 4 pistons?

[Mechanicboy]

Yes, see more in my movies, there are the wankel engie running with one rotor.

[anth4484]

where do i get one?

[Mechanicboy]

The hobbyshop where you live there are selling the OS engines, ask the seller to order the wankel engine if he has not the engine in his shop.. : )

[mymischief1]

i have one, love it! never had a plane, just wanted the engine - built a test stand for it, had it run for many hours, only minor wear inside, but sticky fuel residue

revs from idle to top rpm (~16000) within 1/2 second with a small prop

highly recommended!!!

[bamskyline]

best on youtube

thank you!!!

[haks0894]

So incredibly simple yet So effective!

[OK2BCK]

its a pump

[Mechanicboy]

Yes, it works as a rotary pump, also the wankel engine was designed as a pump before Felix Wankel took the construction of the pump and maked the first Wankel engine. :)

[jumpmaster98]

are they really that small? or just a example toy thingy.

[Mechanicboy]

Yes, they are really small model engine produced by OS engines Mfg.

The 1.3 horsepower are not realistic measured by OS engines Mfg. Can be lower hp than 1.3.. Not measured with tachometer and propeller size and calculated with Thrusthp program.

[darkeyce02]

wher did the small thing come from

[dwnrety1]

a RX-7 pooped it out

[RFTAEC100]

LMAO XD

[svlion1977]

HAHAHA

[djahriman]

That is sooo cute!

[jsdhesmith5]

I know, that little fellas ready to rock!

[southernboy125]

isnt that backwards

[CHickenWing00794]

where do you buy this??

Can you take it in a mopped??

[theguy1224]

Awesome, where did you get this? I want one!!!

[joesabido]

That an "OS Engines 49-PI Type II" RC aircraft engine, it produces 1.3hp @ 17,000 RPM and the practical RPM range goes from 2,500 to 18,000

[Jaakkoseta]

it is rolling in wrong direction by the way

[Mechanicboy]

Allready answered in early message..

[oisiaa]

As I was going along on a 27 mile bike ride today, I was day dreaming about putting one of these on my bicycle. I was intending on using a 100:1 harmonic drive to reduce the rpm and then connect it to the front sprocket so I could still use the gears. I don't know if a small harmonic drive could handle the RPM or the torque though.

[njipods]

dont worry about the torque mate there wont be any lol

[tamiyatruck]

can you put that in a nitro rc car

[Mechanicboy]

Can put in the rc car, but where are cooling of the engine.. The engine are developing extreme hot than reciprocating engines.

[zajdabneeg]

by the look on the block they have those sticking out fin that can help for cooling or what they call cooling fin. Like regular gasoline block they have that too. I don't think its nessasary to throw in a water jacket cooling system onto this thing. R/C Tunner might consider using a cooling fan to blow on the motor while its idleling and not moving.

[zajdabneeg]

holly shait a mini rotary dang i want one lol iamam put it on my r/c

[kcole939]

That thing would actually make your R/C fast despite how small it is, looks like a toy but it revs to 18,000 rpm and makes 1.27 horsepower.

[zajdabneeg]

I actually like it better compare to the regular block that looks like a lawn mower block. lol and 1.27 hp? humm it be super fast.

[kcole939]

Might seem funny, but by the actual horsepower formula, this engine could theoretically move around 200 pounds, at 180 feet a minute.

[zajdabneeg]

200/180 = 1.11 pound/feet of torque.

[kcole939]

That's why I mentioned theoretically, because I honestly think this engine makes less than .10 ft.-lbs. of torque.

[chabbalato]

yeah 1hp is probably a little too much for an RC car!!

[rcmadness13]

actually its not. the .24 bigblock os's can push a lota horse. somewhere between 2-4..

[breedam]

no, hey usually have more

[ReisendeEuropa]

Actually some of them have 4-6hp

[JokerPokerUberSmoker]

crap... if so that little thing got as much horsepowers as i do :D

[JokerPokerUberSmoker]

but i dont have the same rpm :P

[AkinaGod]

Where did you get this?

[rednecksinspace]

Any hobby shop or site like towerhobbies[dot]com. It's made by O.S.

[CHickenWing00794]

hi, how many ccm ??

[zink669]

wow

[watchforfinger]

where can i get a mini rotary engine

[30GB]

too bad its costs $400 for this little one damn

[30GB]

it is for rc

[thegreatkoua]

do they make this engine anymore?

[DangerousAernscht]

Yes. It's from O.S. Engines, search for "49-PI Type II .30 Wankel Rotary Engine" or take a look at their website.

[yontopapa]

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

[mcwheels69hs]

A wankel is a rotary. they're refered to as Wankel after Felix Wankel, the dude who invented the rotary.

[shiveyy]

whats the difference between a wankel and a normal rotary engine?

[herbienbrian]

so tiny, yet so powerful o.o

[1BustedMyth]

The main thing I came accross a lot was people saying they use oil (burn oil), meaning they think the rings are worn. firstly they dont have rings and 2nd, they are designed to use a little oil, as there is a oil injection port in the carby, this lubricates the apex seals (rings) as if it were a 2 stroke. (there is no bath of oil under the rotor (piston) like a piston engine. So they are meant to use a little sump oil from new.

[tjgame2]

What is that motor from , it looks small.

[compaqeo]

bike mabe?

[tjgame2]

I looked them up they are for rc airplane's, holy crap they are expensive.

[compaqeo]

oh my guess would be small pocket bike lol shit that plane must Fly...lol wow didnt mean that

[creedence18]

where do you find them?

[creedence18]

what site do you look them up on?

[tjgame2]

ebay had some. I have no idea about this stuff so I dont know if they were any good or not.

[pottersrevenge]

Probably one of the greatest engines ever in my opinion. Just make sure to check the oil periodically and it will last you practically forever.

[1BustedMyth]

I was the proud owner of a fully restored original RX2, my pride and joy, the car with 1200cc used

to upset a lot of V8 owners! :)

The big thing with these engines is that you have to warm them up before you put them under

load. they are designed to run very hot, so there is actualy slop on the rotor until the metal

expands and takes it proper spot, if loaded while cold the apex getts slammed into the wall and

marks it, then the seal runs over the mark and wears out (chattering).

[trex65ghia]

You got it kinda right. They are engines that run hot but not by design and the design of the slope as you call it was to take advantage of the heat and metal diffraction. These motors are known to not seel very good with or without letting them warm up....

[1BustedMyth]

Techlec

Mate, dont you mean NITRIC oxides?

If it was Nitrous Oxide I would be very happy-literally!! :)

[TECHKLEC]

HAHA...Yeah, I'm hip. Actually, the proper term as far as emmisions goes is NOx, such as nitrogen oxide, dinitrogen trioxide, dinitrogen pentoxide and others (party gas included).

[douro20]

I believe this is a Graupner/OS Wankel, and if it is, it needs oil mixed with the fuel.

[nebunu1force]

is there a roller bearing between the eccentric shaft and the rotor? if not... is it possible to fit a rotary with bearings? Tnx:D

[Mechanicboy]

Yes, there are needle roller bearing fitted to the rotor.

[TECHKLEC]

??????

[bagdouche]

if anybodys wondering N/A rotory motors can definately take a beating (depending on material of apex seals, 13b, 12a). i would say just as reliable as a toyota honda whatever you prefer. forced induction is what kills it.

[TECHKLEC]

Forced induction (turbocharging, supercharcing) adds more stress to any engine, rotary or reciprocating.

[chapmasi]

Anyone seen one of these converted to run on LPG???

Few people say they can no problems, but no-one in the UK does it :(

[1BustedMyth]

Yep they run on LPG just fine and will run on Hydrogen well also.

I think in Japan they have a duel fuel RX7 has a tank for LPG and another for Hydrogen.

[silviaa71]

wow, this is an OS wankel...a motor for rc plane... fantastic

[TestECull]

:P You were turning it backwards, just so ya know. lol.

[bestfunnyvids]

no he's not idiot

[LamenessFTW]

rotary is a good concept but things wear down too quickly in reality for it to meet its full potential.

[0nametaken0]

actually rotary is a lot more durable than piston driven engines. there are a lot less moving parts involved therefore less wear and tear. however it is hard to rotaries to meet emission standards and they are just not what you called a gas saver.

[boby13]

it's true, rotary engines have less moving parts but i've heard that they are less reliable... i don't know if that's true

[Mechanicboy]

In the first wankel engines was less reliable due material was not good. Today in modern times, nothing to be worried, as long as you treat the engine nicely and keep good maintenance, they will last long.

[boby13]

modern rotary engines are called RENESIS... so those are the ones that do work fine? thanks for clearing that out... I love rotary engines :D

[rotorminded]

dat nitro?

[rcpro17]

YES

[rotorminded]

thougth so coz glow plug where u get \that n how much..?

[rcpro17]

tower use to sell them not anymore. it was like a specail adition airplane engine. they also had an inline four nitro engine. you could buy them just have to search

[JoshatSuzuki]

those things r gas hogs... if they ran more effeciently, they would be cool

[unaccurate]

but they have a shit load of power whitch evens it out.

[Fhantom2040]

how an mini remesis

[mazb6t]

thats wicked man! a little pp rotary ha!

[falling14]

way to run it backwards

[Zoloft61]

is that a OS Wankel motor?

back in the 80's there were some major cooling problems with this motor. Have they solved those yet?

[Mechanicboy]

Yes, this is a OS wankel engine. Do not lean out the engine and use 20% castor oil in fuel to prevent the engine overheating.

[thesecretfox1]

lol

[Timechanging]

thats a rotary engine

[canti1988]

wankel i love that word

[videojosh20]

That's a model engine right?

[Mechanicboy]

Yes, it is a model engine.

[Helivz]

I bought two of those in the summer of 1997 when they were under $200.00 a piece. Now, they go around $400.00 for one, or high $300.00s. Never ran them. When will someone invent a twin or triple rotor Wankel for small models? Liquid cooled too will be good.

[Einstiensblackid]

There's no way to stack them? I know they do that with mazdas.

[12valvepower1]

the gears in a rotary only locate the rotor yes.. the con-eccentric shaft is what is pushed on to produce power yes?

[Mechanicboy]

Correct answered.. :)

[V8Tourqe]

im sure you know already that your turning it backwards

[Mechanicboy]

I has allready wrote the comments, scroll down and find where i wrote..

[oOillillOo]

i was wondering where u got the small sized wankel engine becouse i am interested in getting a small version and testing compression ratios to move up to a larger 12a or 13b.

[aaron9696024]

its an o.s. wankel they are on the website i think its called a .49 type II wankel

[oOillillOo]

thanks for the info

[kasanovakai]

he said "rotax engine are not a wankel engine". That is true

[coldasiice]

Put that bad boy in a 1/10 RC scale Mazda RX8.
