The Huey had two blades because it was a teetering rotor system. A second set could have been mounted, but there was no point since two did the job and the extra mechanism would have reduced reliability and increased even routine maintenance time. The Blackhawk needed more lift and was fitted with an articulated rotor system (each blade could move independently), which reduced the challenges associated with stacking teetering rotor attachments.
I am now 70, had fixed wing private, never converted, but flew left seat a few times Bell 204, UH-1 and twin turbines, our company owned, building power lines. Health, and eye site got my licenses 25 years ago. MISS THOSE DAYS
WOW! This video brings back some fond memories. I used to love it when the aircraft transitioned through that "ETL shudder" and the ride suddenly becomes so much smoother and quieter. WORWAC 80-39
I was going to say this looks almost like a Ft Rucker syllabus. They did a pretty good job. The only video Ive seen where the crew actually wraps the throttle closed to split the needles.
@Blacksheep61 Pulling the collective up increases pitch (collectively) to the main rotor blades. It doesn't increase rotor RPM. If anything it decreases engine and rotor RPM. In this type of aircraft those decreases are offset by a governor automatically adjusting fuel flow to maintain a constant RPM. I never flew a twin engine Huey, but I suspect that what you think is a 2nd twist grip (the indented gear-like shape) is in fact the device used to increase or decrease friction to the collective.
Blades are generally independent replacement items. The entire rotor system is "balanced" and 'tracked' to ensure a smooth ride via several adjustments, to include adding weight to a blade, adjusting trim tabs, adjusting the pitch relative to the mast, and adjusting a lead-lag linkage
After a good number of flights in a UH1-D, just the sound of one starting up gets me anxious to fly in one again! The only thing missing is the feel ot the frame moving side to side as the rotors start to spin!
@Blacksheep61 No sweat. It's been a long time since I flew a Huey (C&D Models). The start up procedures are a distant memory,, but I have remembered most of the control layouts and flight dynamics. Besides, if you're Navy or Marines, you get allowances for slow thinking. ;-) If you've served, or are serving, my best wishes and thanks. AND, Go Army, Beat Navy. :-)
The way it works, is that the pilot (on the right) has the cyclic and collective, and the pedals. Cyclic stick in the center, which controls the main rotor, and the collective is that lever on his left which is next to the seat. The collective has the throttle on the lever as two twist grips which control fuel flow (seen at 0:42). You pull the entire collective up toward you to increase Nr (rotor speed) and ascend. The engine start switch is on the collective panel (his thumb is on it at 0:33).

You can tell from the start procedure they were trained at Ft Rucker, US Army flight school. They did skip some important steps. Use of check list and Hover Power Check - just to name a few.
Good summary, but on this model huey there is only one throttle twist grip since it is a single engine aircraft. Also the starter switch is on the bottom of the collective just above the twist grip. It is a trigger pulled by the index finger.
Pilot in right seat seems busy checking things. Basically just turn battery on, starter/generator to start, fuel on, set throttle to idle, pull starter trigger, release trigger at 40% N1. It's running. I always thought it was designed by geniuses to be flown by your basic Army pilot. That would be me.
The Marine Corps still uses the UH-1 only they are now onto the Yankee version. The UH-1Y. I believe some Army units still use them for Medivacs as well in the CONUS only though.
This pilot seems to have a lot going on in the cockpit during the start process. I fly 212's and we can usually be up and running (save for the daily after start checks) within approximately 2 minutes. I noticed that the pilot in this video sure seems to have his hands in motion very frequently and is all over the place flipping switches, but, perhaps the Japanese flight checklists are different from the ones in the USA. Any information would be helpful. A nice video to be sure!
One pilot can, but the Navy usually requires that a pilot qualified in any helicopter is in the left seat, and can navigate, perform commications, and double check everything the pilot does.
@choprjock Yeah, I've learned that since I made the comment. The NATOPS which I read was for the UH-1N, but I know the twist grips adjust fuel flow to either engine to control Nr.
Strange startup procedure, many power cutoffs... tubine exhaust temperature alarm lights on gauge around 3:44 when he powers off again. I can´t understand why he does that continously, those turbines are so delicate to that sudden changes.
Something I noticed and wondered about, from what I could see on the tachometer , when he exercised the governor it looked like he didn't return NR to 100%, he left it just above the green RPM range at around 105-107%. Is it normal to takeoff at more than 100% NR, and if so why? Or was I looking at it wrong? And another question, do UH-1 pilots reduce NR at high cruise speeds to reduce advancing tip speed so it doesn't approach super sonic? I know some newer aircraft with FADEC's employ automatic NR reduction for high speed cruise to reduce advancing tip speed and retreating blade drag.
Gives pilots bragging rights---until someone points out that most of them have to do with radios and lights. There are only half a dozen dealing with really important things like fuel cutoff, generator operation, rpm limiter, and such.
40% 40 seconds or 400F degrees is starter release on a UH1H model, whether it starts or not. You always should see the clock second hand reset pushed before start, for that reason.
It is obvious when the engine ignites, however the start button should continue to be held down until the "gas producer" gage reaches 40% rpm or a maximum time of 40 seconds has passed, usually only 10 to 15 seconds. George Keppel, former IP, Army Aviation School
@choprjock Lol actually I made that comment before I had ever flown an aircraft in my life. I was going strictly from reading the flight manual of a school instructor, and I'm going through commissioning training and flight school now. And as a matter of fact, I am Navy, so go Navy, beat Army ;) Thank you for what you've done, soldier.
No chopper in existence today sounds as good as these did. Iconic. Great video too.
The increase of rpm at about 1:43... I always got goosebumps when the turbine reached that pitch.
This is the best sound ever. Sitting in the left cranking this puppy up. The feeling of pulling pitch can't be beat.
The Huey had two blades because it was a teetering rotor system. A second set could have been mounted, but there was no point since two did the job and the extra mechanism would have reduced reliability and increased even routine maintenance time. The Blackhawk needed more lift and was fitted with an articulated rotor system (each blade could move independently), which reduced the challenges associated with stacking teetering rotor attachments.
But it lost that cool blade flap sound when coming in fast...
Quite possibly the BEST clip of the Huey yet - fantastic sound! She's a beaut and will remain an all time favourite!

I like the roaring start at 0:52 :)
Me too,,love the horizon indicator rolling as well lol..

must be awesome to fly a bird like the huey
You haven't seen nothing you should research the Blackhawk helicopter.
Thanks for the pics of this flying legend!

Love the sound of the engine 👍
to ride in one of these would be PURE Motivation on my part, exactly what I need right now
I know people love airplane startups, but helicopters are amazing because you get the turbine startup, and then you get the whoosh of the rotor

I've flown twice in a helicopter when I was a teenager. Brother and I both. Would happily go back up in one if given the opportunity.

I miss flying. Just Robbies, a squirrel and a BK117 but god would I have loved to fly a huey!
+CliffordSGM had a good time too in these flying machines, really hoping I can get back into the cockpit! Flying greetings from Zurich Switzerland!
DCS world in VR if you can't in real life. Still pretty amazing
A thousand moving parts rotating rapidly around an oil leak waiting for metal fatigue to set in
Pilot in right seat seems busy checking things.
Basically just turn battery on, starter/generator to start, fuel on, set throttle to idle, pull starter trigger, release trigger at 40% N1. It's running.
I always thought it was designed by geniuses to be flown by your basic Army pilot. That would be me.
Really? I thought a single pilot could fly these things.
Certainly gives you a new appreciation for the pilots and chopper!
nice vintage panel ! love this turbine sound !
They didn't flip enough switches and press enough buttons if you ask me.
Lol.
It simple to start. Just flip a couple of switch.
No kidding. I think it was for the camera, or the hottie holding it!!
Awesome. Thank you for sharing this!!
乗ってみたいわ〜😱✨💕
お勤めご苦労様です🙇🏻♂️✨💕😊

That pilot has been around the huey block a number of times.
Epic!
Sure does!
Is this bill Yost from 80-6/80-17?, Possibly 80-39?
Christopher Lewis 80-39.
Some people have all the fun.
love the clicks of the switches
Great video, thank you for sharing!
One pilot can, but the Navy usually requires that a pilot qualified in any helicopter is in the left seat, and can navigate, perform commications, and double check everything the pilot does.
Whawww! such awesome machine! awesome way of steering/control!!!!!!
We used to play "Paint it Black" from the Rolling Stones over the speakers...confuses the fuck out of the VC
Low RPM audio turned off? Low RPM alarm should go off in the beginning.
かっこぇぇ～
エンジン音もステキｗ
@choprjock Yeah, I've learned that since I made the comment. The NATOPS which I read was for the UH-1N, but I know the twist grips adjust fuel flow to either engine to control Nr.
Good Stuff! Thanks for sharing this experience with us! Cheers.

@ .18, sounds like he says, "Fifty cents" :) Great video by the way.
El sonido de la turbina en el segundo 51 es uno de los sonidos más impresionantes que he vivido.
Muy buenos estos pilotos...Los felicito desde la Rep. Dominicana.
Why I did not see the pilot's hand rotating the throttle at the moment of light-off during startup??...
Rotor sound. . great
was that thing out of balance? or perhaps the tiniest amount of collective on? seemed like a violent start-up
best heli ever invented,,,,,,,,,,,,,,,,
So great this Video!
214 big lifter...now that's a sexy unit
Is that the same huey used in the VIETNAM WAR?
start the video and open ac/dc thunderstuck in the background
航空服がまだ迷彩仕様じゃない時だ懐かしい
UH-1 Long live the king!
@opd1mary
They're not Chinese. They pilots for JASDF which is Japan's military branch of their air force.
dudes a studednt pilot on a 1st flight, props to him.
Japanese self defense force is awsome!
BELLISSIMO!!!!!!!!!!!
nice vintage panel !
Without a doubt brother.
Damn they are growing in numbers... Look 9!!!
Well...of course pilots know the procedures, but they always refer to checklist. Thats why they have it. Precision is everything. :-)

Nice video!! thanks for share!!
i wonder if the ground crew did a salute... I tried to peer over my laptop to see.
damn why using too much switches ? i'm confused
@DannyDad208 good job mate. always dreamed of flying something. i still have time to achieve it.
Did you achieve your dream yet?
At what point does the pilot turn the starter off? When does the turbine become self running so no starter is needed?
SanFranciscoBayy let your finger off the trigger under the collective
+SanFranciscoBay 40-60%? think it depends on the engine.

I can feel im in the cabin on the hele, just great.
I am curious if there are odd numbered blades like 3, 5 or 7 bladed helicopters.
@anglosax001 You will find the co-pilot would be cross checking.
@choprjock Lol actually I made that comment before I had ever flown an aircraft in my life. I was going strictly from reading the flight manual of a school instructor, and I'm going through commissioning training and flight school now.

Thanx for sharing :)
excellent vid!
Only bad thing is that this video wasn't long enough. I was just getting into the flying scenes when it ended.
Very good
Hell yeah! Love that sound.
nice video
2:40 he is splitting the needles to check the integrity of the clutch
NICE VID
...but if we could know what buttons he touches everytime, that would be great..
I want one, way too cool!
Busy Hands.... Just gets on with it.
because it sounds better? I think the troops in the field could care less about which one sounds better.
Which one is the cigarette lighter ?
@cuzzythewolf2 Only if you can fly pass godzilla first...
How late would you be to work if it took you 6 1/2 minutes to start your car in the morning? I would be at least, 6 1/2 minutes later.
Best job in the world
Put a shaker on the center column during startup and after your flight open it. Easiest. Martini. Ever. No manual shaking required!
500 часов на вертолете такой полет ощущаю!!!
AT the start it sounds like the "wave engine turbine" in Yamato (space version)
Run Charlie!
Japanese aviators wearing white gloves just seems to fit their meta, I don’t know why.
