I love how the guy answers questions totally his own way, as if the question was never asked or something.
Great interview, however the pilot didn't know what he was talking about on many of the systems. The barber pole (red line on the airspeed indicator) is at the 129 knot mark. This 129 knot mark represents VNE on certain aspects of flight. Doors off or if there are items attached to the outside of the helicopter. It's not your "cruise Speed" indicator like the pilot stated.
Auto rotation speed is generally done at 60 KIAS, not 130-150 knots like the pilot indicated by pointing near the top of the airspeed indicator. The YSAS switch has nothing to do with smoothness of flight in the cyclic or as the pilot stated, "takes the firmness out of the stick." He is confusing the YSAS with the one-way lock (which actually contains hydraulic fluid). There is a yaw detection gyro under the co-pilot seat. If the device detects any sort of yaw movement in flight, a signal is sent to the rear vertical stabilizer (co-pilot side) and it automatically adjusts so that the aircraft remains in trim.
The pilot has absolutely no idea how the notar system works. He never discussed what actually causes the anti-torque. It has nothing to do with the rotating cone in the back. The exhaust directed toward the left produces no thrust whatsoever. The exhaust is directed in this direction so that it doesn't disrupt the coanda effect which is precisely how the anti-torque works. This is how the notar system works:
There is a 13 bladed variable pitch fan enclosed in the upper portion of the tailboom. As more pedal is applied, the notar fan blades pitch angles change to force more air down the tailboom. The moving of the pedals also change the rotating cone and the pilot side vertical stabilizer. The moving of the rotating cone is only for directional control in a hover.
In a hover, the anti-torque works using the Coanda Effect. On the co-pilot side of the tailboom, there are 2 slots that extend along the side of the tailboom. Low pressure air exits these slots and hugs the skin of the tailboom. High pressure air (downwash) from the main rotor system hugs the curvature of the tailboom, accelerates around the striker plate (or strake) on the pilot side of the the tailboom and dissipates as it reaches the bottom. The high pressure on the pilot side from the rotor downwash creates a lift vector in the opposite direction (since the co-pilot side consists of low pressure air from the slots). Is sounds complex but it is actually very simple. The tailboom acts like a wing. High pressure on one side and low pressure on the other.
Mark William do you make these for a living? Wow😯😳

Don't try to be a know it all, With age comes wisdom. I have flown since Viet Nam. Who do you think you are? I am a retired General, U.S. army. Flew just about everything that flies. settle down son, I can spout off the same stats from watching you tube. Have some respect for fellow Aviators. If you are one..
Richard Woods I’m definitely not a know it all but I know this aircraft. Not from reading about it on the internet. I have over 6,000 hours PIC in the 520N, 3000+ in this exact aircraft N520HB. At least if you put info out on the internet, make sure it’s correct. retired General 😂.
No, but I have over 6000 hours PIC in this type and it pisses me off when other aviators put blatantly incorrect info out because their egos are bigger than their brains.
Man that's a sporty, smooth, powerful machine!

Well Boeing, which owns MD intellectual property, owns the patent but it doesn't matter as it expired over a decade ago.
fuck patents i wish they didnt exist

Thanks for getting those NOTAR shots Nick! I've always wondered about the physical nature of those systems.
And thanks Evan for showing us around your MD520N! You've got to be very proud of that machine!

*36:34** Tower: guys you're doing all the landscaping there*
I used to see two of these all the time and was always impressed with how quite they are and their subtle sound.
Nick, interesting. I flew these for Phoenix PD. It is a 500. Very fun to fly and very responsive to inputs but not powerful in hot weather. Phoenix is above sea level and experiences high temps. We referred to the NOTAR as a the SLOWTAR. The "aerodynamic" nose slows it down compared to the D model's round nose. In forward flight the pointy nose is more flat plane drag (remember that the nose pitches down in forward flight and presents the upper part of the windscreen in a flat fasion). The pilots who flew both said the D model was considerably faster inspite of its smaller engine. The Notar is inefficient for power used for anti-torque, especially compared to tailrotors (I have been told that as much as 55% of the C250-20R's horse power is needed for HOGI in a NOTAR compared to only 15% for a traditional tailrotor model). The pedal inputs are mushy compared to a very crisp and responsive tail rotor version. I can only assume that that is why the US Army didn't want them.
We patrolled the city with nine of them (first seven produced), did lots of rescues in our mountain preserves (150' long line), swift water rescue, fought fires with a very small bambi bucket and inserted our SWAT folks on the skids. The department was averaging over ten thousand hours a year with the first seven NOTARS. We got rid of them because of poor product support and went back to tailrotors with another manufacturer (Eurocopter-Airbus) who could support us, and even a small twin Agusta for hoisting rescues.
The 520N NOTARs are very successful Police Helicopters at sea-level. Above sea level and hot temps; no bueno. The NOTARS are great for Great Brittain (902 is quite popular there) and coastal areas in the US, where there are generally low DA's that allow it to shine.
So your the one who would orbit over our house in the middle of the night. The notar is quiet compared to others for sure. Now we live in the far NW valley. We traded I-17 and police helicopter noise (27 ave & camelback) for F-16 and F-35 noise from Luke. But none of them bothered us. Thank you for looking out for our safety. Be safe!
Stephen Konegni As a kid in Phoenix, I would watch you guys buzz around in these things and be amazed. I was kind of sad when you switched over to the Eurocopters. Still miss that unmistakable NOTAR sound over Phoenix.
Stephen, I was a crew chief on the OH6A in the Republic of Vietnam in 1968. We couldn't get parts. We had to get parts from the boneyard. The Cong would blow up the boneyard. The reason the Army didn't want the OH was the politics of Lyndon Johnson. LBJ wanted that piece of junk, Bell.
Bell was located in Texas. Howard Hughes created the OH helicopter. We loved the OH because it didn't have hydraulics. Push pull was a great concept. Only a small hydraulic in each 4 of the individual struts. It was crash proof. When we were loaded with a mini-gun and our hand weapons, we had to skid down the runway to take off. We put metal skid plates, manufactured by us, under the skids to save on replacing the skids. I was trained on the UH and then the OH in 5 months. I was promoted to E-5 in 5 months. The foot pedals had a vibration and would put the pilots feet to sleep. We put a piece metal on the rear strut to stop the vibration. I suppose that's why the configuration was changed. Sometimes we have to change out the drive shaft that was out of balance. I have been with a pilot that ran out of gas in Indian country. I've stood on the skids with my M-16, 3 magazines taped together for quick reload, hand grenades, not belted in, and shot up all kinds of Cong schitt. I had a great pilot. Had trouble with the Allison not wanting to start. Anytime running out of fuel, we had to push tail down to reprime fuel pump. Rotor blades changed out as we had a bullet hit em. I won't bore ya any longer. I've got stories galore. Best to ya. Eaglegards 🦅... I'm a totally permanently disabled combat vet. My V.A. care sucks. Fifty years of those criminal bastards is beyond belief! My brother was a Cobra pilot in Vietnam.
Living and growing up in Phoenix in the 90's I actually miss the MD520s and their distinguishable sound and their style. I don't really like the eurocopter styling or the sound they make. I remember one circling over my old home when I was younger for a barricade situation. and it was flying so low we could see inside the cockpit and see the swat guy hanging out the side, they were using the PA to yell at people to go inside. It was something that stuck with me for a long time and I was upset to learnt hey sold them off. I know one went to California and one went to New Zealand. Still a very unique heli that became almost a symbol in Phoenix. The blue paint job was something else.
Also, Phoenix isn't above sea level its below sea level.
Probably the best walk through I have seen.
Always loved this bird. never knew 99% of what they talked about.
Excellent look at the MD500 range of copters! Watched the entire review and must say it really shows the level of advancement from my days as a forward observer in a army observe platform from the early 1970s! Thanks for the review Nick!
Nick, this video is VERY informative and Evans 'easy translation' and operation of the 520N is simply brilliant. Thanks to you both for the time and effort taken to present this to the wider public. FANTASTIC!!
I've been a fan of the notar system for some time, but I always assumed it was shooting exhaust down the tail. now i see how it really works thank you for this video. one of my favorites!!! :-)
Evan is quite a good pilot. He makes flying look easy.
i fly like that in GTA V
Thanks Nick and Evan for such an in dept coverage. Good interview and Evan is great at explaining stuff plus great piloting skills. I'm glad he did the demo flight at low level so everyone could see how maneuverable this thing is. Beautiful machine!
It is amazing this was filmed 6 years ago , time flies !
This Heli is awesome... The pilot evidently knows his way around this aircrafts maneuverability as well... great vid... love all the info included and shots made... nice!
I was a crew chief ,door gunner in Vietnam back in the 60's. I was in the test project unit at Fort Knox. It is the best helicopter ever. Easy to fly. You brought back a lot of memories. THANK YOU!!
Always got to be some jet pilots who taxi in for a photo op in the background! Definitely maneuvers very smoothly and efficiently in close quarters behind hangar. Shows how well it operates in tight areas. Nice job. Makes my goal of saving more money for flight school even more achievable.
Agreed
Great video Nick! Really love this chopper
Thank you to Nick and Evan for an awesome tour ! Loved it ! More more !!!
15% faster than a Cessna.... and 10,000% more money and 8x’s the operating cost... I NEED IT!!!!! :D
but it's one spinny boi
Can you land a cessna in your back yard?

Interviewer is a very patient man.
Nick you are a natural at interviewing.
Evan has a brilliant calm re-assuring manner, exudes confidence.
Impressive.
Many thanks to both of you, & your crew.
Cheers
This is the most awkward one I’ve seen. Nick doesn’t act like he knows anything in this one and that guy doesn’t know anything about his aircraft. He can’t even get right the notar section. The bucket or thrust vectoring tip is only for fine tuning the remaining thrust just gets vented out threw it. The slot in the right side of the tail boom is doing 95% of the anti torque work. And the bucket on the end does 2% the vertical stabs about 60kts they really help because well I flew the md902medevac version before we got rid of them. They were slow as hell and LTE (Loss of tail rotor effectiveness) is a problem.
Thank you Nick for sharing these video's. I have, since a child always fantasized about helicopters, heli's have always been my biggest and first love. At school as a kid every project I had to produce was about helicopters. It just makes me realize how I have wasted my life by not fulfilling my dream of piloting these awesome machines as nowadays it is way too expensive to be a student, especially at my age but I take absolute solace and pleasure at knowing that there are people like you that produce videos like this where I can somewhat enjoy the dream... Keep bringing them on mate....
What a beauty this chopper is and that signature md sound is fantastic.
1.25 million dollar aircraft and the man has a flip phone ...Nice
Thrifty old man
He's not trying to impress everyone with his iPhone...
what's wrong with using flip phone? humble man does not speak too loud but very heavy pocket. arrogant man speak louder but empty pocket. dont judge the book by flip cover.
I'm not sure but Maybe 3G causes less interference with the copter's electronics, tho it didn't look too advanced.
It may be because those flip phones are much easier to carry in your pocket.
Cool video Nick!!! I love watching these☺️
Nick, This has been one of the most enjoyable of your videos ever.
For someone that knows next to nothing about helicopters, I felt that I'd actually learnt something with this one with Evans patient explanations and demonstrations, He should have his own channel!!
The NOTAR system is just so diabolical simple. Having been a Huey guy for many years.....this makes so much sense.
Helicopter...
by far the coolest machine ever built by man!

And go-carts.
@ >>> THAT is a DIFFERENT KIND of *_"RIDE"._*
😜😜😜😜
@Stable Genius >>> Yeah, but they do not TRAVEL very far...😊
@Stable Genius >>> _"da vinci"?_
This aircraft is amazing. Thanks Evan for the tour and explanation of how everything works. I like the sound it makes and I to can't figure out why the NOTAR is not more commonly used, it is far safer. Even the helicopters with the closed in rotor is safer.
I like the teardrop look with the pointed nose. Big improvement on it older model looks. Just no storage for anything, but then it was a military derived helicopter. A great looking and brilliant machine. Thanks for showing us around one.
Yeah i love the Fenestron style tail rotor.
Loved the detail on how the notar works. Thanks to the owner who explain it all. Always loved the looks of this heli.
Evan's an awesome guy to hang around, always willing to help or give rides in his helicopter specially to kids. All around great guy!!
But keep your daughters away! ;)
This was cool to recognize my home airport right from the beginning! Ive always wondered about this specific NOTAR machine being a pilot working on my rotor transition.
As a non pilot I say that was an amazing flight. I rarely watch a review longer than 20 minutes, but this one was so enjoyable even thought I didn't understand jack.
Its partly(50%) because its a helicopter, they're some of the most amazing machines ever created .... and the other part (50%) is because of the producer - Nick Murray. I don't personally know him but he has that love/affection towards helicopters that all of pilots have but he has also taken the extra step and has actually flown them and documented his adventures along the way. Big kudos to him !!!!!! Keep the videos coming !!!!
Very VERY! Nice Demo. Wanted to fly since i was 12 years old from the first time i saw a Bell 47. i got the Bug and it still lives in me to this day. i guess I'll never know the exhilarating joy.
Thanx for sharing.
Nick that was a wonderful presentation! Big thank you goes to you and Buddy. We want Buddy to present every single chopper that he has flown.
1.25 million. How much for the little one you have in your hand? I'm on a budget.
"You can crab really well in this"; "In either direction?"'; "Oh yes, I'll show you"... aircraft flips orientation 180 and crabs in same direction (but opposite relative to ground due to 180)... that works in my book!
Amazing video, I have always loved the Little Bird, such an agile chopper in all of its' forms. Especially effective during special forces insertions and extractions, you can set it down on a wall with a good enough pilot. These were known as Loaches during the Vietnam War, and were key in effective small squad insertions in enemy controlled territory by elite special forces such as SOG. What an amazing aircraft!
Always wondered how those things worked with no rail rotor.
Very interesting, thanks for the post.
Nick, I am a fanatic with this type of helicopters,NOTAR, actually I love the whole MD serie,since it was HUGHES,you should do a review on the MD900 EXPLORER,keep up the good work and keep those great videos coming.
You made my day! This was sooo interesting! Never seen such a helicopter :-)
Here's my NOTAR story. Forever as a kid my doodles were always aircraft. Existing A/C or imagined. Coincidentally, while in school at Hanscom field to obtain my A&P, I was killing some time and drawing a futuristic helicopter that had no tail rotor and instead, ducted engine exhaust down the tail boom and metered the exit to manage the anti torque. This beautiful machine seems to have a better system. When I drew that concept helicopter was many years before MD introduced this machine. I was so amazed the first time I actually saw one of these which was in Naples, Florida. Great videos dude.
Thanks for the post, very interesting...the EC135 has always been my favorite heli but this one looks like a lot of fun.
This is a re-edited version of this video, I have added some additional footage, cleaned up some of the sound issues at the end and added CC
Thanks!
Your productions often have a higher quality than many multi million dollar ones. :)
Was hoping this was a full-flight version!
Great videos, anyway!
Should I re-post my smart alec comments?
Totally!
"weather Vane" Effect on that large tail section when hovering in cross wind???
This man in the blue reminds me of my old boss they might even be related spooky, I always love this chopper every since Magnum Pi.
My brother and I actually had a chance to buy the 500 used in Magnum P.I. For just the cost of a hot end rebuild.Also a 206 jet ranger the guy reduced price on because he needed the money for the Long Ranger he had ordered to service the Forest Service..It was so long ago,that an r22 could be had for 88,000.00 Beta model.......Trained at Heiser Aviation in Corona Calif.
One of the more iconic designs in aviation history, and it keeps getting better.
All this time I thought a helicopter could not work without a tail rotor. You learn something new every day.
Not sure if I missed it, but I would have liked to hear a brief history of the flight experience of the owner/pilot.
I did hear him mention how many he's owned but not his beginning, i wonder too.
SanFranciscoBay ... my question exactly. Perhaps a Vietnam pilot?? And then he went on to rule his world. To own and pilot your own helicopter for pleasure is not a cheap hobby. I suspect he uses it in his widget manufacturing business
Nice video and very interesting, great machine. I've prefer the look of the older, domed shaped MD500 but appreciate reasons for the change.
Really nice bird. Thanks for the great interview with such an experienced owner/pilot.
Thanks for this review. I’ve always wondered about the NOTAR and why it seemed to fade away, but it turns out after all these years they are still produced. Wonderful machine. I’m not a pilot, but am lucky to have rides in Bell 47, Jet Ranger, Huey. Keep up the good work.
Nick, I'm a retired British Airline Captain. Never flown a helicopter.That was very interesting... as are all your videos. Thanks for that.
I am glad you enjoyed the video. Slowly working on improving my production values.
hi nick iam disabled in wheelchair please watch my channel vids about my life and please gift me dji phantom4 or mavic pro thank you.
You are asking for a gift from sympathy? Your pathetic
Tommy ,you’re.
Great video, thanks for posting.
I LOVE THE VIVALDI INTRO!!! It's just SO epic. Good match up.
Awesome work as always Nick!!!
That's amazing! When I get some big bucks I'm getting one of those!
thats a sweet leaf blower...
Awesome video on my favorite helicopter, what a work of art and engineering
Very interesting and well done video. Thanks for producing and what a smooth pilot. He's a great representative for demonstrating the capabilities of that fine machine.
Shoutout to this guy for still having a flip phone. Lol!
Nick, nice video. The tail fan blades are operated at constant RPM but the blade pitch does change with pedal input, I fell like this guy presented it as fixed pitch during your walk-around. He could have moved the pedals for you when looking into the fan intake area. The YSAS switch turns on/off the Yaw Stability Augmentation System. This system involves a yaw sensing gyro system and the right vertical tail stabilizer. The system enhances handling qualities by detecting yaw movements and changing the angle of the right vertical stabilizer with electric actuators. Nothing to do with the firmness of the stick.
Video was so soothing and relaxing to watch, my eyes were actually starting to close just sitting here...
My favorite bird, awesome work Nick!
I always thought they use the exhaust pressure for this instead of an extra fan.
Worked on the prototype back in 1980 or 81 at Hughes Paloma’s airport I remember the fan being very loud
My dad's company built the Wooden Test stands for both the AH64 and the Hughes 500 at Palomar McClelland.
I Was watching a video I come across randomly of a guy flying around LA which I found fascinating. Now I’ve come across a fellow kiwi living in the States who does car reviews and is a pilot. How cool.
Thank you Nick for this very informative video of how the NOTAR system works. Definitely a unique sounding helicopter 👍
wonderful

Headphones and engine on at about 32:50, then a beautiful flight demonstration. 🎧 🚁 🤘🏻
Thanks for the Famil of the MD520NOTAR Nick. It's great to see someone like Evan, who you can see loved this aircraft, his passion shows in his talk of the helicopters feature's. I always thought the NOTAR System was the Engine Exhaust, not a push fan at the start of the boom, so learned something there.
Very interesting aircraft
Mr. Nick;
Thank you for all you do for those folks that love aviation, God bless you and please, bring some more. Everything you do, is an important thing for every one, again thaks.

When he red buttoned the phone call😅.. this guy reminds me so much of my dad even kind of looks like him my dad flew an 800 back in the day he would have loved this model.
one of my favorites. I consider the MD 5xx as the Miata of helicopters and the Gazelle as the Corvette.
Very small:) Been next to a Mil Mi-6 and it was HUGE.

Today Evan took me for a ride in this beauty. Heck of a ride and I wish I had your job. Thanks!!
the sound design is interesting,
awsome internal side prop accustics..
otherwise the typical and really lovable MD-blade sounds, gotta love it!
I flew in a tail rotor version of this in Texas for a hog shoot. We flew over hundreds upon hundreds of acres blasting the hell out of pest hogs. It was glorious
I'm jealous, good fun.
yikes, what a badass shooting at animals from a helicopter. you could go to a retirement home and start beating the shit out of old people too.

30:50 For start up and flight.
Well done ..... Perfect presentation .. I love that chopper ...
Thanks to Evan for taking the time to do this. I hope MD helicopters recovers from financial ruin and continues to operate.
Walking into a tail rotor....hmmm. maybe it's just time to go then, thinning the herd
Tail rotor is invisible at speed. All it takes is a lapse of judgment to walk around the rear of the helicopter instead of the front. If you've logged any time at all in these things you would understand how easy it would be for someone to make that mistake.
@@greasebob ... especially if your airplane qualified where the engine (propeller) is at the front. If you go to switch seats or trade sides, your instinct is to do so via the rear. Bad habits can kill quickly in aviation.
He said we can do auto rotation but never showed it. :(
Hey! I worked on this design at McDonnell-Douglas Helicopter out in Mesa, AZ.! It's a great helicopter.
But the guy talking is wrong. 80% of the anti-torque comes from the slots on the side of the boom and a phenomena called the Coanda Effect. The air coming through the slots makes the boom behave as though it is a wing (in a vertical orientation) countering the torque of the helicopter. The rotor blast provides the air flow. The interesting thing is that the more thrust that you pull with the collective, the harder the boom works to counter the torque. It is nearly self-compensating. I optimized that effect with the amount of air pulled into the boom with the 13 bladed, variable-pitch, fan in the base of the boom. The pitch of these blades is also tied to the collective and cyclic inputs for best performance. At low speeds the boom does most of the work and the swivel cone on the end does the rest and gives you yaw control. At high speed, the H-tail does most of the anti-torque work with the assistance of the boom. Another thing of note is that the right side vertical of the H-tail is completely disconnected mechanically from the pedals and is controlled by an electronic SAS system... Stability Augmentation System. If you notice when the guy pulled on the left vertical, the right vertical did not move. They are not coupled. During early flight testing, as the helicopter comes in to land at a slow speed and high angles of attack, the H-tail is complete blanketed from the air stream and we could not easily control it. So we installed a SAS system to handle that. If you watch video footage of a 520N coming in for a landing, you will see the right side vertical bob back and forth to stabilize the helicopter.
Great video, Nick!
I think the 520 series is a very sexy bird...
Couple of unquestioned answers here :-):The civilian 500s are flown from the left seat (primary) to make it easier to configure for three across seating in front. I have heard that the inefficiency in the NOTAR versions is mainly internal aerodynamics in the tailboom. The Coanda effect of the boundary layer control around the boom helps cancel torque "automatically" when you pull pitch, but I wonder how much of a benefit that really is to the pilot? That's what the pedals are for, and the two-bladed tail rotor works fine, costs less, is more efficient, etc. What's the verdict among pilots who have owned it and flowned it? :-)
In Vietnam, pilot was left seat. I flew in the right seat as a crew chief. I could tell ya stories that would make ya head spin. I flew with fearless pilots. We never had any issues except for the skids wearing out so we put a skid plate under them manufactured by us. The vibration was in the pedals due to a vibration in the rear struts. We put a piece of metal on the rear strut. We're talking 1968. We couldn't get parts. Remember, LBJ wanted the Bell helicopter. Eaglegards 🦅...
no personal experience but talking with a career pilot friend that flew Apaches in the army, and is now a civilian pilot, says the notar lacks a lot performance wise in hot and/or high altitude environments. sluggish and dull compared to a traditional tailrotor. but he would reiterate that is in hot and/or high altitude environments
A man of many talents Nick. 👌🇳🇿
I enjoy your videos so much! Thank you very much for teaching us, and showing us all about the different types of aircraft!
Wow! I want one. (Reaches for lottery ticket...)
this was a cool video for a non helicopter savy person, ive always been impressed by things that i don't know how works..um, yeah. anyways the owner was very thorough (i think id be annoyed if i knew my shit thorough) and had that old man wiseness and stubbornness to boot. great video, you kiwi.
Nick, your videos are very detailed. The first one I watched was the one about the Huey and got hooked. BTW loved the keychain in the helicopter, "big bucks"
I caught that too, big bucks.... Now I want one. Ebay to the rescue !!!
OK, so I've never come across this channel before. I'm 9 minutes into the video and I have to say I really like and appreciate your production quality. It's not like the over- processed, gaudy garbage that seems to be the norm nowadays. For example, I did not see one instance of chopping up someones dialogue to remove the pauses in speech or cutting "unimportant" information which make statements sound incomplete and unnatural.
Bravo!
And not editing out the taxiing jet or his phone ringing was GOOD. It really was.
I have more positive points I'd like to say, but this is long enough. Excellent, excellent work. Long videos are not a problem when they're made this good, and I look forward to more. Thank you for "keeping it real"!
So this may be a stupid question, but why don't more helicopters use NOTAR? To a layman it seems there a mostly advantages compared to the traditional system (more safe, less maintenance)
lockstocknl ND has a patent on the design
Thanks!
They are also expensive and add weight and take a little getting used to with regards to the delay in response. Advantages are in maintenance and safety as they mentioned and it looks super cool and flies quieter.
I was reading hard about the MD's 4 or 5 years ago, and the story line was, the NOTAR uses more power. So then folks start moaning and groaning about it, say the want all the power that they can get, I'd rather have a tail rotor, blah, blah, blah. One angle the pilot points out that I had not realized is the cruise configuration, where the NOTAR closes, that fin straightens up, and you have a cleaner airframe moving through the air. (aerodynamic force and the vanes countering the torque.) I wonder if this really have a measurable positive effect, or if it is just something the pilot feels. He did stress how smooth and unruffled the bird was in winds. Maybe the top speed is the same, as the NOTAR sucks more power, but I would imagine it would be smoother than a tail rotor version due to being cleaner in the air.
Harry Singh That patent should have run out by now.
Nick, You make no mention of the "Coanda Effect" which is a very important part of maintaining directional control (Torque). en.wikipedia.org/wiki/Coand%C4%83_effect
Did a hell of a job on the production. I love all the camera angles during the hovering portion behind the hanger. Cool helicopter, almost felt like I was there lol.
Great video , I’m only a novice but Evin flow it with ease just looked so smooth in flight thank you
