The power plant of the Edge 540 is an air-cooled six cylinder horizontally opposed engine. The engine code, AEIO540, indicates that the engine is aerobatic (AE), as in the plane can fly upside down with both oil and fuel pressure maintained, the “I” stands for fuel injection, the “O” for horizontally opposed, and 540 for the displacement of the engine in cubic inches. The engine produces 300 horsepower, and while the specific output may seem low, it’s important to realize that reliability is a much more important factor here, with the large displacement engine having relatively low internal stresses. There are also two ignition systems as redundancy for safety.
From the engine, the propeller is directly driven by the crankshaft - there’s no gearbox or gear reduction used, and the engine speed is limited to 2,950 RPM for competition. To optimize the engine speed for competition, a governor is used to maintain the peak propeller RPM. The governor works by altering oil pressure within the propeller, changing the pitch of the blades. The pitch, or angle of attack of the blades, is very much so like the gearing of a car. A fine (or low) pitch is similar to using a lower gear with a high ratio, great for initial acceleration but with a low top speed. A course (or high) pitch is similar to a higher transmission gear with a lower ratio - more efficient and it allows for traveling at higher speeds. The pitch is adjusted constantly to maintain the peak 2950 RPM. From an engineering standpoint, it operates in a similar manner to a continuously variable transmission.
The plane is incredibly light, and yet incredibly rigid. Including the driver, fuel, everything - the plane has a minimum weight of 696 kg, or about 1535 lbs. For comparison, that’s significantly less than a Smart Car, yet with a massive 8.8 liter engine. This ultra-light structure is capable of withstanding up to the 12 g’s of acceleration allowed in competition, and the pilots may sustain anywhere from 6-8 g’s in a long bend. Much like in auto racing where drivers try to stay on the edge of grip, pilots will attempt to get as close to the 12 g mark without crossing over during the race to put down the fastest time.
The plane consists of a steel tube fuselage, and the engineers aim to push the center of gravity of the plane as far back as possible. This makes the plane unstable, but it greatly improves the agility, which is what the pilots want.
Aerodynamics, as you might assume, play a crucial role in competition. While the two seater version of the plane has open wing tips, the competition plane features tips that reduce the influence of vortices disrupting the airflow over the wing, greatly reducing drag. Less drag means the plane can fly faster, and accelerate harder. One of the spots Red Bull has recently innovated is the rudder behind the rear stabilizer. They’ve reduced the size by about 33%, significantly cutting down on drag.
All of the flight controls for rotating the plane are completely man powered. There’s no electronics or hydraulics to assist in maneuvering the plane. Kirby Chambliss will control the rudder with his feat, and the ailerons (or wing flaps), with his hands. One of the features on the wings you might notice are the spades, which connect to the ailerons. These spades act as an air brake, essentially providing an assist when altering the orientation of the ailerons to maneuver the plane. In principle, the idea is very similar to power steering in a car, because as he rotates the aileron, the spade creates a force to help this rotation.
There are also some clever features from a safety standpoint. For example, if the plane were to center punch one of the pylons used in competition, this could block airflow to the engine. No air and the engine dies, and now the pilot has to land without any power. To prevent the engine from stalling, an air flap is located just behind the air intake, and the vacuum of the engine will force this open so surrounding air can feed it. There are enough openings around the engine that the airflow will be sufficient to keep the engine running. There are also cutters on the plane incase a pylon is hit in other locations. Cutters between the spade and the ailerons ensure nothing gets caught in this area, and there are also cutters between the fin and the rudder.

Huge thanks to Red Bull for sponsoring the video!!
There's a Red Bull Air Race happening this weekend at Indy! Link in description for more info; hard to describe what this was like, and this was only peaking around 7 g's, versus 12 g's which is the limit in competition. So nuts!
this is an amazing video even though it isn't about cars!!
How do they limit the G forces?
They limit them for safety reasons, not for competition rules. I would imagine they have an accelerometer on the aircraft that transmits the g-forces.
The planes have sensors in them for the G forces, if a pilot gets above the G limit during his run he will get a time penalty
In the Red Bull air races the planes have to fly a marked course/track(not sure what to call it), one at a time, the pilot with the best time wins (its sort of like rallying)
(Just explaining to make sure my post makes sense ^^)
^ Great explanation
Aviation is amazing. Everything is kept as simple as possible. No "power steering", no liquid cooling, no complex engine sensors. Just the bare minimum needed to get the plane in the air. It's the good parts of old simple cars with the performance of modern technology.
Thank you for this great video! I definitely enjoyed it.
Aviation in general has some of the most complex machines ever built....
Air racing does it represent aviation on general. Just like there are car racing series with bare minimum tech.
Check out modern passenger jets - everything is controlled by computers, electronics and hydraulics ... As complex as it can get.
Exactly, the beauty is in the simplicity.
Y10Q So it's faster and more fuel efficient than a racecar.
Key phrase here being "as simple as possible". The bit missing in the end is "... and no simpler!". It all boils down to necessity. In a small aircraft like that, much like in a go kart, the control forces required aren't too big, so a set of cable linkages is more than sufficient. Your power steering analogy is not applied on the correct scale. In most cars, once you get past a certain weight on the front wheels (which isn't very much) power steering is a necessity, otherwise you'd have a very hard time turning the steering wheel. The controls in small aircraft on the other hand are very easy to manipulate completely unaided and the only forces you're counteracting are the aerodynamic load on the control surfaces, which - again - is fairly small. On an aircraft of that size and weight, the cable and pulley system is the optimum solution. Levers add weight, hydraulics add both weight and complexity and electronic control systems add a prohibitive cost to the airframe (the entire set of cables and pulleys will set you back as much as ONE electric actuator!) while removing a lot of the feel from the control column (which is much more important in a light aircraft than in a car!). Redundant magneto ignition is still used in a lot of piston driven aircraft as other types of ignition systems are deemed too unreliable.
Liquid cooling is unnecessary on an aircraft engine as there is ample ram air available to cool the cylinders, unlike in a car engine, and the extra weight and complexity therefore grant no extra benefit (where in a car you reduce noise and remove another power drain). There are however some liquid cooled aircraft in existence, such as the Hawker Hurricane which had a liquid cooled Rolls-Royce Merlin.
As far as complex engine sensors go, almost everything inside these engines is either mechanical or hydraulic for reasons of reliability. The downside is always extra weight, often less efficiency and usually higher responce times (as inertia places a greater limit on these systems over digital). This is a simple engine meant to operate efficiently in a fairly narrow power band, so most extra bits on cars are unnecessary. The most complex control system is the prop governor which is hydraulic in larger aircraft, but likely entirely mechanical in this one. All the springs, levers, gears, etc. can be replaced by a sensor and an actuator and save a good few kg, but anything with an adequate reliability rating would again be prohibitively expensive.
Larger aircraft require a hydraulic power assist system, otherwise the pilot is physically unable to apply enough force on the control inputs. Gas turbine engines also require more complex control systems to prevent incorrect input from shutting them down. In the past these consisted of numerous levers and hydraulic actuators, all of which have now been replaced by digital FADEC and nobody is looking back to the "glory days" of these systems. Just to go back to your analogy, a single modern commercial gas turbine engine (say the Rolls Royce Trent 1000) has about four times as many complex sensors as your whole car and its FADEC computers alone cost more than a lot of supercars. The difference here is that a strict maintenance regime is followed and the manufacturer's business model is completely different.
After the military, wide body transport aircraft are the biggest adopters of fly by wire technology, which entirely replaces the direct input hydromechanical systems of older aircraft with computer controlled electrohydraulic and more recently - electromechanical actuators and a simpler to construct pilot input system. This allows for augmentation of pilot input to ensure that the aircraft remains within its flight envelope at all times (there's also an OFF switch for that function by the way) and makes it easier to tune the handling of an aircraft artificially in order to maintain consistent feel both throughout different flight modes and across a fleet of different aircraft. Airbus are known for being an early adopter of this method, though a very similar system was required on the Concorde.
Damn, respect for that pilot! A true master at work!
Chambliss is incredible!
Oh hell yeah! I've watched F1 in person before and they seemed too unreal in the way they handled. Their ability to brake and corner seemed fake. However, after watching the guys fly at Ft. Worth a couple years back in the Red Bull Air Race, I can say that watching them fly the pylons is almost cartoonish. The Edge 540 V3 and the MXS-R are absolutely unreal. It just doesn't seem possible that something can move so quickly. If you read this and are near an air race, GO!!! Thanks for the video!
even more fun is motorcycle racing, flat track and moto gp. It doesn't look real at all. Agreed on these planes though, idk what's more impressive....the pilot or the planes abilities
Cherokee140Driver
JEALOUS!!!!!
I thought my flight tonight was intense due to rough air crossing a canyon, but THAT! THAT is intense!
That's so badass man! Such a cool opportunity!
Nice seeing you here, RP!
how about a video explaining how they keep fuel and oil to the engine upside down?
That engine is fuel injected and has two fuel pumps: mechanical and electrical one. The plane isn't in one attitude long enough for fuel to pool away from the pickups. Those planes usually also have inverted oil systems. Christen is one manufacturer of such oil systems you can probably find a diagram of how they are hooked up on the web.
I know with model planes the way you keep fuel to it is by having a weight at the end of the hose in a gas tank (just like a chainsaw or grass trimmer engine, those can also run in any direction, however they are 2-cycle so the oil is mixed with the fuel so orientation really doesn't matter). I'm not entirely sure how the lubrication system on these planes work, and that's a great question. I will probably do a search to find that because now I'm curious too.
ain't worried bout nothing instrumental
Flame Beats or it could have a dual impeller style fuel pump, as used in most fighters - 2A6X4 as well ;)
Flame Beats Mildenhall! You understand the CV-22 fuel system?
2:30 the pilot wasnt messing around, 2 seconds in and already upside down.
That was a hell of a takeoff. Luckily under that regime the plane is gyroscopically stabilized by the mass of the pilot's balls.
Yeah, pretty wild from start to finish haha.
This video has a wrong title. It should be "How pure joy and happiness looks like" :)
OR 'The Most Fun You Can Have In Someone Else's Clothes!'
Dude I didn't realize but your channel is getting this big man. I remember subscribing you when your channel was small and now it's fuego.
Congrats on maintaining consciousness and not vomiting! I would have been puking like crazy if I went for that ride haha. This was a really cool and well done video Jason!
Having had rides in various aerobatics planes (pitts special, extra 300, extra 200), you're definitely right about the intensity!
The only thing I've ever experienced which is more overwhelming is motorsport...
Your expression is worth a thousand words. That looks fantastic!
Every single time that shows the plane ride you were smiling.. That really shows you enjoyment.. Congrats Keep up with this awesome channel..
The production quality of this video was top notch, Jason! Glad to see you having the opportunity to do crazy cool stuff like this.
Almost at a million subscribers! Good job man! Keep it up
glad you got the experience. You definitely made a better passenger than I would have. My commentary would be "and this is when I screamed like a girl right after I screamed like a girl but right before I screamed like a girl." The poor pilot would be deaf by the time he landed :)
What a day that must have been! Thanks for sharing.
Love all the camera work and editing, really nice work. Keep it up! :)
I am an aircraft power plant technician, and I love that you made a video about planes. If at all possible, you should do a video from the Reno air races.
That was incredible! You have to upload a longer video with more footage and hopefully some behind the scenes stuff!!!
wow what an experience!! they say there is nothing that comes remotely close to the feeling of flying. Thanks for sharing your awesome opportunity!
Awesome video! That's definitly on my bucket list.
So awesome! Will you do any additional detailed videos about some of the subsystems?
What a cool experience.
Man... I am so happy for you! This looks incredibly fun!
more please. there's so much you could talk about here!
Can we get a long edit of this ride?! Love it!
When it comes to planes, there really is no replacement for displacement. love the lycoming O-540's. Tough engines.
you fly these planes?
Nope, fix em. I primarily work with pistons so lycoming and continental engines. Not a lot of horsepower, but gobs of torque in those things.
Wow what a privilege! These amazing vehicles surpass any other. A great read is "No Visible Horizon" and gives a great insight into the world and insight into the history of aerobatic flying. Those guys and girls get truly beaten up in there and are the best pilots in the world.
Been a long term fan of your channel and i've been dying for an aerospace related video (as that's what i'm studying at uni) thanks for uploading another great video pal.
Hey Jason, I've been wanting for a long time to see engineering videos about aviation. Just wanted to let you know I, and I think many others would be eager to see more of these.
That looks crazy! Can't believe you didn't get sick or anything!
I just watch Destin for smarter everyday in a T-38, So you guys had plane fun lately, I'm jealous! this is crazy flying !
So freaking awesome. So jealous right now.
What an awesome experience! Thank you for sharing.
That's awesome that you had the opportunity to do something so friggin sick!
JEALOUS LEVEL OVER 9000!!!!!1!!!!!
Next video you tear into the engineering of everything, right? *Hopeful-puppy-dog-expression* Right...?
One would have to go into quite a bit of depth on this in order to explain it properly, definitely longer than a single video. You sure you're up for this?
233kosta ab so lute ly
It's not going to happen, but a guy can dream.
I'm half tempted to do a video series on the engineering of aircraft and spacecraft myself, but I don't even know where to start on this :P How do you explain all that to an absolute beginner?
Maybe don't try to explain it to an absolute beginner. Do an intermediate-level video assuming the viewer has basic understandings of aerodynamics, engineering, materials, etc. People who don't know anything about that won't like the video, but people like me whose engineering career revolves around potash mining and basic machine shops would appreciate some mental stimulation! :)
I believe there to be an acute lack of non-beginner level engineering videos on UA-cam. Maybe that's what the Great Courses Plus is for...
Good to see a machine other than cars. Engineering is so vast, I love to see more expanding into other areas like this.
It's so great to see this kind of video by this channel. aviation is my life and to see it being shared is awesome thank you so much for the video :)
subs should hit 1 mil by the morning. good job
Great collaboration! Another video covering the engine in more detail, particular a compare/contrast video, would be really enjoyable for a lot of us.
great idea
riding one of those is one of my dream! thanks for sharing
Loved it! Really glad you got to experience that.
Yeah, "a little nauseous". I did too after a trip in a Chipmunk about 20 years ago - not as performant as the Red Bull but the same, unforgettable, stomach-upsetting fun.
I just went to the races in Indianapolis this past Sunday, it was cool to see a feature about the technology in these planes up close.
Awesome!
Dude this is awesome, your channel keeps getting better and better. Also Kirby = LEGEND!!
awesome to watch 7G wow thats some serious force! thanks for sharing :)
More engine info would have been good. Glad you had fun!
Well this was great! Maybe you make a video on oiling system and fuel system (especially carburettors) for aircraft engines some day? That would be very interesting.
This is absolutely brilliant! Engineering Explained certainly ought to include aerospace engineering.
That looked like a blast!
When I saw this in my subscriptions I thought that you were in Indianapolis, they've got a race at the IMS tomorrow. Would love to ride in one.
That was awesome! We need more plane videos!
UA-cam mraviation101
Wow! As you can tell from my channel I'm heavily biased in favour of airplanes over cars, but I've never been in an aerobatic airplane (and I still very much enjoy your videos about automotive technology). It's very high on my bucket list, though. My first will probably be a somewhat less capable, but still very impressive Super Decathlon, as that's what my flight school has.
Thanks and keep up the good work.
Man.. I love what you do, having I little bit of an issue with your decision to go from an STI to that lemon in your garage haha.. but it's a period of adjustment, + I'm sure with all your knowledge, that s2000 will eventually have a few secrets under the hood. A++ content man!!
its bin on my bucket list to fly one of this beautiful machines
Only one word... Awesome!
That looks so awesome!
I was in a similarish plane a couple weeks back. It was an amazing experience. The driver said we had maximum of 6 positive and 3 negative G's. I didn't have any problems with that, except it felt somewhat funny. Of course the G forces didn't apply for more than a few seconds at a time and we had some straight level flying between the stunts. I can't say I'd recommend such a ride to anyone, but hell it was fun and I'll go anytime again, if I just have a chance.
this is awesome man! Great video!
Great vid Jason thanks
Propellers themselves are actually more efficient at lower speeds (you get more thrust out of less power). The problem is of course if a plane goes too slow it will stall, so the plane has to go fast. At rest, a cessna's prop will produce 37lb of thrust out of 2 horsepower, while the same plane going 75mph will only get maybe 200lb thrust out of 50 hp.
The purpose of variable prop pitch is to be able to 1) go faster without redlining the engine, and 2) avoid high tip speeds, since the closer the propeller's tips get to mach 1, it creates more drag and the propeller becomes less efficient.
The reason high prop pitch generally isn't as efficient is because you are pushing air at an angle- so more air is pushed sideways (which is wasted) instead of backwards - which produces forward thrust.
I hope you don't confuse airplane speed for propeller speed.
Do you mean that a cessna prop produces 37 lb at 2hp, at zero airplane speed?
And I hope you mean that if *prop speed* goes up but airplane speed *doesn't* it will NOT produce 25 times more thrust at 50hp than 2hp?
Please clarify.
Awesome. Simply, awesome.
OK Jason, as I've said in the past, you have the coolest job. But this tops the cake.
I'm very fortunate, indeed! Such an experience!
Hi, love the videos man. Could you be able to do a video on what a stroker kit does for the engine? Thanks so much.
Im jealous! great vid! well edited!
His voice at the end... hilarious :p
Great graphics!
That's bucket-list stuff, awsome!!!!
You talking about engineering: great
You talking about aircraft engineering: AWESOME!, please do more of this
Props for holding your food. Nice video!
I'd be either or both, vomiting or screaming like a little girl on Christmas. Need more video!
Whoa, insane views! That was really amazing!
being a pilot on one of theese things must requre a lot of talent
Nah
I figure it requires more conditioning than talent. Kind of like NASCAR drivers. It's not so much that these vehicles are hard to drive but not just anyone can handle them without physically struggling in some way.
Ask the Blue Angels about that! :D
+AzuMentch36 the blue Angel can't do the stuff that these planes do.
+Peter Schmidt The talent is important too.
Incredible Jason. 👍🏼👍🏼 for not throwing up in his plane. But I have to say he made you look like a bobble head. 😂😂.
Yep, probably concussed haha. Hit the sides pretty hard a few times. I was quite dazed after getting out!
A 172 is about as intense as it gets for me, but this is just amazing!
ah the lycoming engine...its 540 ci and 300hp in the aeio trim...these engines are perfect for propeller driven airplanes because of the 3000rpm speed limit for the prop itself,low reving, lightweight and considered 100% reliable when properly maintained...you could put a corvette motor in a plane but will need a gear reduction unit to keep safe prop speed
Just a few seconds in, already wondering if that is a Fieseler Storch in the background?
BRILLIANT!!
That looks amazing. Nice!
I puckered when he went upside down through the rock!!!
So jealous of you Jason! Quick random question- What did you use to attach the GoPro to the outside? I'd have thought most mounts would try and let go at those forces. Lol
***** Thanks! No way in hell I'd trust my GoPro on any old mount anyway 😂
seedorfj is correct!
that looks like so much fun, is there a price tag on this or is it just because your awsome and have an audience?
One of my favorite UA-camrs and one of my favorite pilots? that's a like from me.
EXTREMLY AWESOME!!!
OMG luckiest experience ever...AMAZING
BRAVE MAN!
Oh my that looks like a fun ride. I hope you didn't eat before that flight! I did that once and I felt sick for the rest of the day.
That's awesome!! Thanks for sharing your experience!
It seems that the flight itself is much worse for the passenger than the pilot - the pilot knows what maneuvre he will do next, and can prepare his body by proper muscle tension. The passenger does not know what's coming, and as you said, can bang his head against the insides of the cabin... Were you aware about the details of the flight (what aerobatics in what order will be performed)?
good point. its like being thrown around
thought exactly the same - can see pilot counteracting his upcoming moves with head/neck @ 2:48.... passenger on the other hand just gets flopped around
Oh Jeez Kirby didn't go easy on you haha! That looked like the real deal! XD
Wow that looks insane
How can you take 7g without the g suit? Is it because the duration isnt as long and its more of peak g? Damn impressive stuff tho
So happy for you man :))))
:)
I did similar ride out of Scottsdale AZ a/p in the late 1970s in Pitts. BUT I got the WORSE migraine headache not air sick. AND the head ash nocked me on my ass for easy 6 hours AND had to hide in the dark, since the sun light hurt my brain so much,.....
You coming to Prescott anytime soon?
Would love to meet you to talk about engineering!
Nice! Wish the video was longer, though.
Holy cow! He didn't waste any time getting to the fun stuff, lol!
Ah that's wonderful, I've flown in aerobatic aircraft and love it.
Cool video. Heads up, you got the propeller explanation backwards. A higher angle creates more thrust, but but is less efficient (similar to 1st gear in your analogy) while a shallower angle is used at higher speeds. Also ailerons are not the same as flaps :)
Uhh, no, full forward on the prop lever is low pitch and used on takeoff, landing, and slow flight. The prop lever is pulled back during cruise increasing the pitch, efficiency, and the "bite" of air the propeller takes.
Lucky guy! Now we'll go buy some Red Bull so they get their money's worth.
And with your new wings you can do this! /s
Nice!
