Simply awesome dude, I am a MM and studied the Wankel after buying an RX3 in the 70's, can't tell you how beating a car with a V8 off the mark felt with these little gems, but warming the engine was critical for the seals, I loaned the car to someone for a week and it came back sick. IDIOT right :( Owned 3 rotaries, but that was when I could afford the fuel lol This build from scratch is amazing (but having a lathe is a blessing and essential tool for the smarter of us - always loved metalwork!), well done Johnny, God Force has truly blessed you!
I have a hatred of the rotary engine. That revealed however this little bugger is to be admired. So to is the work you managed to create it. With RPM so high it has real potential for use . I'm deeply impressed by what you produced and truly admire that you kept at it, until it runs well. Beautifully machined parts.
With parts like bushings and keys, etc, it's always good to make a couple like you did. If you have time to make one, you have time to make two. No one ever said "Man I really wish I didn't have a set of replacement parts". I'm glad you went back to dual carb, I love the way they look, especially on classics.
Simply amazing. One of the best videos I have ever seen. I'm a huge fan of the rotary engine and to see it scaled down to that size is simply amazing!!

You certainly did a beautiful job machining all the parts for this twin rotor. It turned out very nice. I was looking at your cooling fins knowing these motors run very hot. Then i realised the amount of fuel you put through the engine provided the additional cooling. I used to run a Mazda RX8 rotary but it only manged 45000 miles before requiring new apex seals. Would be great to see your engine installed in an aircraft.
I can respect the intricacy and the time and the planning is just amazing I'm a mechanic myself and I know you can't just pick up a screwdriver and do this thing this guy has to be a NASA engineer very impressive
Terrific project! Congratulations. I love these little OS Wankels and have two of them. One thing, a propellor, in addition to providing the rotational momentum like your flywheel, also functions as a radiator fan to push air over the fins on the engine to cool it. Your IR camera didn't show things to be too bad, but in the long run that may be a problem. I suppose you could use an external fan for bench running.
@@inoahmann7542 Hahaha... oil cooling through oil loss, it will still overheat the rear rotor and housing. In a loaded application with a proper tune, it will certainly overheat. The rear rotor and housing is in a draft shadow AND if intended for an enclosed under a car shell and used at high rpm (14,000 is a pointless operational rev anyway) it won't last long. As stated, easier and better ways to configure multi-rotor engines given a gear reduction drive will be used anyway.
@@BTW... Not oil cooling, actually evaporative cooling from excess methanol boiling off and not being burned. It has a very strong cooling effect. To brake in a nitro engine in cold weather you need to block off all it's cooling fins because otherwise it'll never get up to operating temp, and that's running the engine with a load, sometimes running it wot for a few seconds at a time. In a car it would need a cooling duct and fan to run with a proper tune but these engines don't need a ton of cooling like gas engines do. I don't know about this engine specifically, but I've seen os rotary engines rev out to 25-29k before (unloaded). Most nitro engines can rev in excess of 30k rpm and some can rev over 40k.
What a great machinist you are and surprised how responsive the engine was and how quickly it returned to idle when you let the throttle off. Best wishes to you, from, Auckland, New Zealand. Awesome vid and great camera and sound.
I have one of the O.S. Wankel engines, intending to use it in a Piper Cub R/C model. I broke it in properly, but have never run it further than that. The price of these things is ridiculous now. I ran mine for break-in with a prop on it to ensure cooling of the engine, by the way, otherwise the engine gets very hot as you showed. Congrats on this project!
"...so I replaced it with a dual-carb setup..."...as if this takes only seconds to do, hah! (I was in awe.) AMAZING craftsmanship, beautiful to watch. And, a most excellent video! THANK YOU for posting!

I can't even imagine how this is only possible... The tolerances and all the thinking for each and every parts. It looks alien to me, honestly ! Fantastic work!
Nice line trimmer motor. I remember these OS motors from the 70's. Expensive and totally unreliable. In hobby stores they became the ultimate dust collectors.
I had a friend that put a pair of them in a scale DC3. I saw it on the flight line many, many times, but I don't ever remember seeing it with both motors running at the same time.
I remember in the early 90's you could buy a wankle engine for a rc airplane, never saw one run, no internet back then, but you are doing a great job...
Now I'm really fascinated by Flowmax mufflers. They had sound engineers design them to give optimum performance with less noise. Noise is the ONE thing I dislike about these small engines. Add a big muffler and it might not work at all. It's not very easy to make a good one, but I wish I could find one for these small class of engines.
Beautiful work, as always. How did you disassemble and fix the seized engine when the rotor dug in? I’d suggest using a propeller rather than a flywheel for forced cooling.
Proud moment for me. Well done my friend. You have done exceptionally well and persevered with your build. I'm sure if you're a true rotar head you're already working on a triple and quad motor. Lot's of respect for your work 🤜🤛
My son is in his first year of aerospace engineering, I told him to watch your channel and try to replicate your products as a challenge for his engineering class.
Beautiful work. Every mechanical apparatus takes months/years of thought and design more than one prototype plus countless hours of test bed operation to iron out the bugs. Still you never know if you've found all of the devices weak points. never give up, you're almost at perfection on this one. I can see it powering my focke wulf 190D 9. Good luck to you!
This thing is super cool and when it comes to the single carb making run lean I believe it’s because you have the airflow doing two 90 degree turns before entering the engine the fuel in the mixture is getting caught on these turns especially the first one I think it would work if it was a less aggressive angle off into each cylinder
Wow, I am sure many of us would love to do this. And many, including me, would fail for many reasons. So it's nice to see you doing what we would like to do. How much time did you spend on this project?
Could you do a 4 rotor or even a 5 or 6 rotor version of this? I think it would be incredibly interesting to watch and see how something like that would perform!
thanks for the video John. I enjoyed watching the process very much. The best way to learn is from mistakes, if nobody made mistakes, we wouldn't grow and learn as a people.
This is absolutely amazing. The amount of time it must’ve taken to build this little engine. I cannot even imagine having that kind of patience. Very well done.

You talked me into it, I subbed. Good call!
Hey JohnnyQ90! I really admire your work, like jewelers precision. If I was rich, I'd buy something from you, but, I'm not. Very satisfying.
These projects that I've seen you make are absolutely incredible. Very impressive!
Its crazy how extremely fast the RPMs drop to idle. Its almost as if its idling as you rev it lol so cool. Has the Rotor idle and 2T sound.
Its normal for a very very little engine
@@chriscoolTV Largely rotating mass, though, right? Racing engines on actual vehicles respond very similarly.
i have no words. this is amazing. you should be super proud of your knowledge. well done!
You made something that works, wastes a lot of fuel, makes a lot of noise = PERFECT !!!
Sounds like it runs pretty smooth! It's always exciting when you upload a new video about this project. Looking forward to the next one :)

Anna is a beautiful girl.
He's the person I love, he's my light
day. The way the music flows and sounds
is extravagant and fun. Anna is
icon, legend, beautiful girl, princess, inspiration,
a star. I could go on and on, understand this.
I love NBA Anna.#垃圾
Since you specialize in small engines, it would be fun to see you do a "large" engine, such as a 49cc moped engine, but as a V8 or maybe an inline 6. I'd love to have a V8 moped.
Agreed
Here ya go. This is so cool. ua-cam.com/video/KyP7lCO6WBg/v-deo.html
like keith57000's v10 engine
Straight six moped. Or maybe somehow a small scale diesel??
Awesome series would love to see you continue to increase the amount of rotors

@Operaatio eeeh how about stopping at the 26b engine or what is in the mazda 787 racecar. 4 rotors.
You made this from scratch? Wow!
After the time/money spent on it...I'd DEFINITELY be running it rich AF lol
A lot better than melting or seizing it up.
Incredible work 🙏🏻
I can't even imagine how this is only possible... The tolerances and all the thinking for each and every parts. It looks alien to me, honestly ! Fantastic work!
Imagine the toy action man's face getting this fitted into his little plastic car
You are one heck of an engineer and fabricator to say the least.
Im digging the baby veocity stacks on the carbs. The whole thing is pure art work.
I really admire someone who builds something like this. 👍 Great job! And it sounds amazing.
Потрясающе! Отклик на подачу топлива и максимальные обороты выше всяких похвал! 👍🤝
Nice line trimmer motor. I remember these OS motors from the 70's. Expensive and totally unreliable. In hobby stores they became the ultimate dust collectors.
I had a friend that put a pair of them in a scale DC3. I saw it on the flight line many, many times, but I don't ever remember seeing it with both motors running at the same time.
I remember in the early 90's you could buy a wankle engine for a rc airplane, never saw one run, no internet back then, but you are doing a great job...
You must be an aerospace machinist. Beautiful ultra fine intense craftsmanship. Enjoyed watching your amazing build.
Now I'm really fascinated by Flowmax mufflers. They had sound engineers design them to give optimum performance with less noise.
Noise is the ONE thing I dislike about these small engines. Add a big muffler and it might not work at all. It's not very easy to make a good one, but I wish I could find one for these small class of engines.
Never really thought of that. You bring up a great point
Beautiful work, as always. How did you disassemble and fix the seized engine when the rotor dug in? I’d suggest using a propeller rather than a flywheel for forced cooling.
Proud moment for me. Well done my friend. You have done exceptionally well and persevered with your build. I'm sure if you're a true rotar head you're already working on a triple and quad motor. Lot's of respect for your work 🤜🤛
What s beautiful build! I was glued to it.
My son is in his first year of aerospace engineering, I told him to watch your channel and try to replicate your products as a challenge for his engineering class.
Beautiful work. Every mechanical apparatus takes months/years of thought and design more than one prototype plus countless hours of test bed operation to iron out the bugs. Still you never know if you've found all of the devices weak points. never give up, you're almost at perfection on this one. I can see it powering my focke wulf 190D 9. Good luck to you!
This thing is super cool and when it comes to the single carb making run lean I believe it’s because you have the airflow doing two 90 degree turns before entering the engine the fuel in the mixture is getting caught on these turns especially the first one I think it would work if it was a less aggressive angle off into each cylinder
It is also the fact that the is trying to move twice as much air through the carb. If he had one rated for the airflow it would work.
Now it needs a scale Mazda RX3 chassis and body

I'm an Electric Guy but I LOVE what you did there it's so nicely homemade, looks amazing crazy little powerplant
The sound is ridiculous good any rc car with that will be extremely fun👍
Wow, I am sure many of us would love to do this. And many, including me, would fail for many reasons. So it's nice to see you doing what we would like to do. How much time did you spend on this project?
his skill set is really boss level, bravo
I think I'd fail at the think about it phase.
@@qofiagya4891 Wow amazing 😮 I'd love to meet you Anna ❤ 😘
Could you do a 4 rotor or even a 5 or 6 rotor version of this? I think it would be incredibly interesting to watch and see how something like that would perform!
this is so wonderfully satisfying to watch, and I'm in awe of your skill and design abilities. Great stuff! :)
This is awesome man, thank you!, Should do a 4 rotor, that would be very unique and also awesome!
The way everything slides into its place is magnificent 😄👍🏼👍🏼
Have you ever seen the liquid piston engine? Great work.
Time for two more rotors. We love twins but quadruplets are way more fun when it comes to dorito shaped engine parts!
Sure, overheats 4 times as fast as a single.
Now this is what you call real content and real talent. Genius
I sperged out on this video hardcore. You are an incredible fabricator/engineer man.
This is really impressive from an engineering standpoint.
Absolutely Truly Amazing and Fantastic. Thank you Very much.
thanks for the video John. I enjoyed watching the process very much.
The best way to learn is from mistakes, if nobody made mistakes, we wouldn't grow and learn as a people.
Respect for your craftmanship and patience !!!!
That idle sounds good
i can learn how the rotary engine system works.. i really like watching videos like this.
This is absolutely ridiculous and I love it. ✊🏾. Beautiful engineering brother
This is probably one of the coolest most impressive things I’ve seen in a long time😮
I'd love one of these for entertaining my neighbours, given they both tried to stuff my planning application for a new garage.
This is absolutely amazing. The amount of time it must’ve taken to build this little engine. I cannot even imagine having that kind of patience. Very well done.
I'll bet you are proud of that eccentric shaft, I would be. Cool project
