The thing that surprises me is that clear cover didn't become clouded up, become crazed, scorched from the heat ,scuffed up, etc. after 5 seconds the engine ran!
Well I almost talked about that when I said "600 runs" in this video, but I withheld that material science information since It took me over 2 months to develop this particular material, with supplier advice from my NASA engineer friends. This material mix is amazing!, And these tests further prove it's durability. I may reveal what it is in the future but it's not exactly glass but is 98% transparent. Maybe I should send you a slug made out of it !.
Nitro engines run very cool. If you see a cylinder head temp of 250+ degrees F the engine isn't long for the world. Thats a "loaded" temp. Bench-testing "idling" engines is pointless.
It looks impressive, doesn't it? Sadly it isn't. RC car and truck engines can generate double the horsepower with half of the displacement at a 50% higher redline. Seriously, I have a RC truck with a 3.4cc piston engine that redlines at 38000rpm and can pop rolling wheelies.
I noticed that when he did the frame comparison that the rotor only did a 3rd of a rotation. Not too familiar with rotaries so i was a little confused.
Same, I was wondering what rotating part he was reading off of with the meter. For example, I was thinking it might have been reading 3x what the actual RPM was if it was reading from the rotor and picking up each corner (the triangle piece). It just seemed strange that it idles ad 5-6,000RPM but I guess it does!
You would measure rpms at eccentric shaft, the output of the engine. You would not measure at the rotor, an internal engine component. We dont care how the engine does it we just need to measure the output. But yes the actual rotor itself will always be rotating much slower than the e shaft, by 1/3, one of the designs strengths.
just like with firearms, I'm so amazed at how fast combustion type engines operate mechanically with how fast the combustion/explosive process occurs, and so efficiently without more breakages... simply incredible
i am a mechanic for over 50 years and i am still amazed at the speeds of engines, intake, compression, power, exhaust cycles... the speed change a piston ,, it stops twice and goes the opposite direction each revolution.. 3000 rpm divided by 60 sec =50 revs per second= 100 direction changes per second... amazing
I was lucky enough to pick up an old _Sachs KM37_ rotary from '64... It took me ages to find! I'd love to pop down to the local auto parts store and pick up things like Apex/side seals (etc.) for it, but sadly rotaries in general aren't all that popular anymore *:(* I really want all that to change though!

I love how it idles at a speed that would instantly pop my 3S. Also, for one fraction of a second at 4:58, it hit PRECISELY 20,000 rpm followed by 22,222 rpm at 5:01. Don't know why, but seeing that was soooo satisfying.

I am not surprised. A single cylinder 2 troke nitro R/C car engine typically reaches 30,000 RPM. A race spec engine can reach as up to 45,000 RPM. 29,000 RPM from a rotary RC aircraft engine is not as unbelievable as you might think. Impressive but not unbelievable.
Theoretically, Rotary engines have no physical limit to how fast they can rotate. The only limits are things like how much fuel and air you can supply, limits of the metals, friction, etc.
Smaller is the system, smaller is the system's time constant, because of less engaged mass into work, so it should be able to get a faster speed, at least in theory
I am pretty sure the rotary triangle spins 3 times for every one rotation of the crank shaft. This gives it an effective engine rpm of 8,333 rpm. I am pretty sure I heard that on a rotary forum at least. So that 45,000 rpm engine would read 15,000 rpm's in the car.

I measured this from the audio in this video and I get it even higher at 30,180 rpm. I used the fundamental frequency of the exhaust sound at the highest RPM which was found by spectrum analysis at 6:25.503s to be 503Hz. Multiplied by 60secs you get 30180 RPM. Fascinating engine and the high speed camera footage is amazing.
Yep you can totally do that, definitely kind of cool I have dab a little bit into ultrasonics in the past, it's kind of cool how you can analyze the footage to determine the RPM. And that amount of RPM is definitely crazy
Great video. This is coming from someone who dislikes rotary engine and will never own a car with one but can admire cool things. I'm also impressed how much this thing takes being essentially passively cooled as you had no fan installed.
Dave Micolichek I figure about 100ft/lb per liter on 2 strokes and would guess the wankle is midway between that and a 4 stroke- maybe 80? Hard to tell, but if I could pour 1oz in that wankle, that'd be 30cc or .03x80ft/lb or 2.4 ft/lb peak I'd guess around 12k?, perhaps 2ft/lb at 16k? So maybe about 6hp? Just my ball park guess with no more than looking at the video with the most basic data.
That engine appears to be a O.S. Engines 49-PI (0.3CU / 4.91CC) based upon size in relation to hands and it's RPM achieved. The 49-PI is reported as outputting 934 watts / 1.24 HP at 17,000 rpm and torque is about 0.37 ft/lbs. So @ 29K rpm it would be outputting ~1500 watts / ~2 HP. All the other engines I've seen are 20CC or larger have thinner fins and lower rpms.
Cerberus984 I thought it was 6 times that-whoops. I estimated 2ft/lbs at peak hp, you say .37ft/lb. So, you think peak torque is at peak rpm? Now that I have displacement, I'd figure 1/6 my up guess- 1hp at ~16krpm
@Jimmy's Tractor I simply used a 2 input toggle calculator that asks for rpm + torque or rpm + hp then solves for other. Then sourced my data from Barnard Microsystems which displays a vast variety of RC engines. The fins are equally thick on the OS engine and has same amount of end plate bolts. Although, the first two fins right of the exhaust port differ from the video I saw to the picture from my data source there were two different generations of that motor. The next step up (different brand) is a 20cc Nitto NR-20EP is significantly larger from the videos I've seen people holding it in their hand or on a bench top.
This is just beautiful to watch! Owner that would have like 1000 cars in his garage but is that poor to only afford one MR2 ZZW30 that soaks his all free budget. xD
29,000 is truly amazing. I've seen you run out of batteries and fuel on other rotary engine videos and this is brilliant research. This concept definitely has legs, despite our world attitude to ic engines as a whole. Small is beautiful. Less oil burning HAS to be a good thing. Good luck with your future research! 29,000. I mean, WOW! 🌟👍
That seems about right on the RPMs since there's so little rotational mass. I've done alot of thinking on the designs used in most rotary engines. Particularly the rotor itself. The biggest problem at the rotary engine faces to prevent it from becoming the best engine ever in my opinion is its efficiency. A lot of its energy is lost before it can never be converted into mechanical energy. I think that can be fixed by rounding off the lobes on the rotor. Making each combustion chamber round instead of square. This would allow one solid ring per combustion chamber rather than the ones that are piece together at the corners and allow some of the energy to escape. The rotary engine an amazing engine just because of its simplicity. So making it even more simple is the best route in my opinion
Whether it be a traditional otto cycle style of engine or this Wankel its not possible to achieve greater efficiency by any of the methods you mentioned. Both of these engines face similar problems with irreversible processes therefore it could be no better than the Otto cycle. For example by rounding off the lobes you'd decrease the combustion cycles efficiency to do work on the rotor. There is a reason the wankel has used basically the same lobe shape since its inception. Lets say that you did find an optimized shape to achieve what you're saying the main problem is still not optimized by doing that. If you'd want to make an ultra efficient Wankel you'd head more towards the material science aspect of things and need to probably look toward the use of materials like ceramic that way you could run hotter fuel, that would do what you said in your original comment. Now of course using ceramic brings in a host of other issues as well and that's the problem.
uncleweirdbeard The lobes and the "wobble" are how it achieves compression. That would be like taking the crank out of a LS, and replacing it with a straight rod. Sure there is still a combustion chamber, but with no compression.
Wankel makes for excellent airplane engine... Where you pretty much set a certain RPM and stay there for extended period of time. By design the Wankel makes for a pretty terrible "car" engine. SO while it does work in ground vehicle applications, the rotary engine is best suited for high RPM airplane engines that only require a narrow rev range.
9 grand? You need to go talk to some Puerto Rican's my man and learn the trade secrets. LOL I can still hear the 13b Starlets banging out ridiculous rpm at Englishtown in my mind. b b b b bbbbbbraaaaaaaaaaaaaaaap! Seriously though, is there something with the side port engine that limits you guys? I would take my Turbo II to 9500rpm all day.
The limiting factor in production rotary engines is the rotating assembly balance. It might not be an issue here as there is only 1 rotor whereas Mazda rotary engine come in 2 and 3 rotor configurations and 4 rotor race applications. If the rotating assembly is too far out of balance spec it will wobble and cause catastrophic failure. Basically the better the rotating assembly is balanced, the longer the engine will last at higher RPM.
That's what I was thinking. 483 revs per second with 3(?) exhaust pulse per revolution should give a note at about 1449Hz. I'm not any kind of musician but that seems to match the note on the video quite well.
That just simply blows my mind how these types of engine operate, it is so amazing and cool and I wish we saw more of these around in cars but it seems like they are shying away.. amazing video man!! Keep up the awesome work!! You just got a new sub!! 😁
@@sandervanderkammen9230 yeah I know that these engine have many problems and I wish they could figure out a way to address the issues and fix them but you fix one thing and another comes up, they have huge potential if the reliability issues ever fixed, I know it's a tough job and fuel efficiency is terrible on them
Wow. Look at all the fuel leaving with the exhaust. I knew these engines rev high, and have the "Brap" like a two stoke. I just wish these engines worked better, and not kill the planet at the same time. I do love that feeling of power they deliver. Dam it. Now I want one.
I am really amazed at the accuracy of the tachometer. Bet you the price was not that high either. Thinking that you could use clear heat glass used on stovetop ranges ??? Maybe a much higher RPM will be capable ??? Since glass acts more like a bearing surface because of the polished surface and the very low thermal expansion you just might be able to go a lot higher in the velocity range. Good luck too.

20k plus rpm that's F1 racing there
luketrembay 29000 rpm is almost double what any f1 motor has done
21,000 rpm is the highest F1 rpm I know of, this thing is approaching jet engine idle speeds 😱
Arch Angel WHAT? No lol, jet engines go up to 50.000 rpm
PC Fanboy I was under the impression that they idled at 50,000 and revved higher on takeoff and flight load.
luketrembay ikr, 20k++ rpm with 10 piston vs 1 doritos
I LOVES the moment when it comes from "Grinder" mode back to idle
I measured this from the audio in this video and I get it even higher at 30,180 rpm. I used the fundamental frequency of the exhaust sound at the highest RPM which was found by spectrum analysis at 6:25.503s to be 503Hz. Multiplied by 60secs you get 30180 RPM.
Fascinating engine and the high speed camera footage is amazing.
Yep you can totally do that, definitely kind of cool I have dab a little bit into ultrasonics in the past, it's kind of cool how you can analyze the footage to determine the RPM. And that amount of RPM is definitely crazy
Thank you
3 combustions , so multiply by 3 should be done, to audio burst frequency
6:16 so this is the sound of an F1 engine 😧
Great video. This is coming from someone who dislikes rotary engine and will never own a car with one but can admire cool things.
I'm also impressed how much this thing takes being essentially passively cooled as you had no fan installed.
Rotary fans be like : I WANT ONE!!!
bravo 099 you're not wrong haha

Incredible, one thing that surprised me was the shape of the combustion chamber⚠️😯
damn that rotary sounds good
At 29k, thats 5.5hp for every ft/lb
Dave Micolichek I figure about 100ft/lb per liter on 2 strokes and would guess the wankle is midway between that and a 4 stroke- maybe 80? Hard to tell, but if I could pour 1oz in that wankle, that'd be 30cc or .03x80ft/lb or 2.4 ft/lb peak I'd guess around 12k?, perhaps 2ft/lb at 16k? So maybe about 6hp? Just my ball park guess with no more than looking at the video with the most basic data.
That engine appears to be a O.S. Engines 49-PI (0.3CU / 4.91CC) based upon size in relation to hands and it's RPM achieved. The 49-PI is reported as outputting 934 watts / 1.24 HP at 17,000 rpm and torque is about 0.37 ft/lbs. So @ 29K rpm it would be outputting ~1500 watts / ~2 HP.
All the other engines I've seen are 20CC or larger have thinner fins and lower rpms.
Cerberus984 I thought it was 6 times that-whoops. I estimated 2ft/lbs at peak hp, you say .37ft/lb. So, you think peak torque is at peak rpm? Now that I have displacement, I'd figure 1/6 my up guess- 1hp at ~16krpm
@Jimmy's Tractor
I simply used a 2 input toggle calculator that asks for rpm + torque or rpm + hp then solves for other. Then sourced my data from Barnard Microsystems which displays a vast variety of RC engines. The fins are equally thick on the OS engine and has same amount of end plate bolts. Although, the first two fins right of the exhaust port differ from the video I saw to the picture from my data source there were two different generations of that motor.
The next step up (different brand) is a 20cc Nitto NR-20EP is significantly larger from the videos I've seen people holding it in their hand or on a bench top.
Cerberus984 cool, looks good. I just guessed.
You know it's good when it starts on the first pull.
I love those mean mini braps lol. You need to make Rob Dahm a mini 4 rotor and put it in an RC car. That would be a good collab video.
Honestly thought that the transparent "flywheel" would be messing up the tachometer but the math really doesn't lie

If you build that thing with 5 liters and turbocharge it you have defently the most powerful engine
You'll also have to hook your fuel line directly to some massive barrels because that will inhale fuel

29,000 is truly amazing. I've seen you run out of batteries and fuel on other rotary engine videos and this is brilliant research. This concept definitely has legs, despite our world attitude to ic engines as a whole. Small is beautiful. Less oil burning HAS to be a good thing. Good luck with your future research! 29,000. I mean, WOW! 🌟👍

That-was absolutely worth watching.
I always wondered why the rotary made a cool sound and now I know why
That seems about right on the RPMs since there's so little rotational mass. I've done alot of thinking on the designs used in most rotary engines. Particularly the rotor itself.
The biggest problem at the rotary engine faces to prevent it from becoming the best engine ever in my opinion is its efficiency. A lot of its energy is lost before it can never be converted into mechanical energy. I think that can be fixed by rounding off the lobes on the rotor. Making each combustion chamber round instead of square. This would allow one solid ring per combustion chamber rather than the ones that are piece together at the corners and allow some of the energy to escape. The rotary engine an amazing engine just because of its simplicity. So making it even more simple is the best route in my opinion
Rotary engines are thermally innefficient by design, what you're thinking won't change that.
Whether it be a traditional otto cycle style of engine or this Wankel its not possible to achieve greater efficiency by any of the methods you mentioned. Both of these engines face similar problems with irreversible processes therefore it could be no better than the Otto cycle. For example by rounding off the lobes you'd decrease the combustion cycles efficiency to do work on the rotor. There is a reason the wankel has used basically the same lobe shape since its inception. Lets say that you did find an optimized shape to achieve what you're saying the main problem is still not optimized by doing that. If you'd want to make an ultra efficient Wankel you'd head more towards the material science aspect of things and need to probably look toward the use of materials like ceramic that way you could run hotter fuel, that would do what you said in your original comment. Now of course using ceramic brings in a host of other issues as well and that's the problem.
uncleweirdbeard
The lobes and the "wobble" are how it achieves compression.
That would be like taking the crank out of a LS, and replacing it with a straight rod. Sure there is still a combustion chamber, but with no compression.
They are actually fairly efficient when run at a single speed with non overlapping ports, but you'll never get good power that way.
Wankel makes for excellent airplane engine... Where you pretty much set a certain RPM and stay there for extended period of time. By design the Wankel makes for a pretty terrible "car" engine. SO while it does work in ground vehicle applications, the rotary engine is best suited for high RPM airplane engines that only require a narrow rev range.
That is amazing. We have our racing RX8's at 9000.
Gawin Grimm so corny
9 grand? You need to go talk to some Puerto Rican's my man and learn the trade secrets. LOL I can still hear the 13b Starlets banging out ridiculous rpm at Englishtown in my mind. b b b b bbbbbbraaaaaaaaaaaaaaaap!
Seriously though, is there something with the side port engine that limits you guys? I would take my Turbo II to 9500rpm all day.
JViello the rx8 13b renesis reliably revs to 10800 stock so you're nothing special.
That's what I figured Unco, thanks for the reply. Sooooo, maybe he meant 19,000 rpm? LOL
The limiting factor in production rotary engines is the rotating assembly balance. It might not be an issue here as there is only 1 rotor whereas Mazda rotary engine come in 2 and 3 rotor configurations and 4 rotor race applications. If the rotating assembly is too far out of balance spec it will wobble and cause catastrophic failure. Basically the better the rotating assembly is balanced, the longer the engine will last at higher RPM.
All things consider no radiator or fan to cooled the little engine, and still held up the abuse. You really know how to make a engine.
The engine was made by Graupner /O.S.
Great, great job! 8:50 "Numbers don't lie" - I like that!
You can try to use a sound analyzer too, for speed measuring
I seem to recall he did that once, using Audacity.
That's what I was thinking. 483 revs per second with 3(?) exhaust pulse per revolution should give a note at about 1449Hz. I'm not any kind of musician but that seems to match the note on the video quite well.
Actualy, it's only 483 exhaust pulses,. The rotor runs at a 1 to 3 ratio...
Nice proof methods! Good job!
That just simply blows my mind how these types of engine operate, it is so amazing and cool and I wish we saw more of these around in cars but it seems like they are shying away.. amazing video man!! Keep up the awesome work!! You just got a new sub!! 😁
These engines suck compared to reciprocating engines
@@sandervanderkammen9230 yeah I know that these engine have many problems and I wish they could figure out a way to address the issues and fix them but you fix one thing and another comes up, they have huge potential if the reliability issues ever fixed, I know it's a tough job and fuel efficiency is terrible on them

I am really amazed at the accuracy of the tachometer. Bet you the price was not that high either. Thinking that you could use clear heat glass used on stovetop ranges ??? Maybe a much higher RPM will be capable ??? Since glass acts more like a bearing surface because of the polished surface and the very low thermal expansion you just might be able to go a lot higher in the velocity range. Good luck too.
