The old voice over work was fine. Perfectly understandable and clear. This text reading tool takes away so much of what I enjoyed from this channel and I can’t believe anyone would genuinely have trouble understanding because a W sounds like V. Your videos are great, comments about your pronunciation / accent are from the petty dorks.
Could not agree more. If I was forced to complain about anything with your reading, I would say at times it sounds maybe a bit flat, but when I come to your channel, I look forward to hearing you speak on the topic. Anyone who cannot understand your accent has no business speaking English.
Agreed ! Genuine, personal, humane voice preferred !!!
Native English speakers might find his accent understandable, but most people who speak English speak it as their second or third language.
Strong accents can be too difficult for these people to understand. I’m sure there were some petty people complaining, but I think most were probably genuine.
All my friends that speak English as a second language can only understand it if it’s spoken with a very generic accent.
@@s4098429 That's a really good observation.
I had no issues with your voice overs. This guy is very clear, but this now sounds like some kind of corporate promotional video now. I thought i must be on the wrong channel at first.
The Joblo wing tips are a fascinating idea. Hopefully someone will run with it in future.
i miss your original voice! this is either a sophisticated british computer, or a sophisticated brit... either way.. i liked the first voice better. is sounded more authentic...
I love your voice mate, was one of my favorite things about the channel. People speak differently to each other, that's one of the joys of life.
Would love a re-upload with the original voice if you feel like it. Thanks for the great work though.
Hey, thanks
@@maxnewberryhtc I agree, I really like the original voice much more than this new one. I like hearing different accents. Plus the original voice sounded like he really cared about the topic.
I prefer your original voice, it’s more authentic. Good content as always!
I appreciate that!
I second this comment! Always prefer natural voice. Please use normal voice in next one :)
Just to be devils advocate I think the new voice will be more popular just because it more closely approximates what many people are used to. Sad that though isn't it? Excellent content too!
I also prefer the original voice. Go listen to Isaac Arthur Science Fiction channel. He has a serious speech impediment. When you start watching it bothers you, and you might leave such comment. But then you get used to it. Thousands of people have.
If there are no privacy reasons to avoid using your own voice I say do it. People come here for aviation news, and you are allowed to be human. I get enough news from computers already :D.
I agree with above comments. Your voice is better than this text reader (though I must say you found a good text reader). Nonetheless, great video. Super informative and interesting.
Well, that change in narrators was kind of jarring, but good content is good content regardless.
It is interesting that they are once again returning to the Wright brother's wing-warping idea after almost 120 years.
The patent expired.
thanks for the video. the old voice was better :-)
My God! So heartwarming to see basically everyone agree that his own voice reading, with imperfections was better. I had expected more disagreement, but was pleasantly surprised, as I'm sure the author is!
Please do your own voice overs, they are much better than a text to speech or professional voice over. The enthusiasm in your voice is one of the reasons I subscribed! Really great content, keep up the great work, but let's hear You! 👌😎
Been a sub from nearly the beggining, I found this much harder to listen to this I had to go and check to make sure it's the right channel. I much prefer your voice. This sounded like a robot. I prefer listening to an actual human. You are the voice for the channel. The content is great. Keep it up.
Thanks Paul. Your comments have always enriched the videos.
"I prefer listening to an actual human. You are the voice for the channel."
I completely agree.
I enjoyed this video very much. Thanks for posting it. Your natural voice gave the channel a unique and authentic feel, please return to it!
I liked the other voice better. This Guy is fine. But it does not feel like he cares about the subject like the first guy
I think this is an AI voice
All of these are sooo cool!!
I prefer the original voice. I very much like your series.
You own voice is great.
I am grateful for the alternative in narrative format, as it is more easily understood.
Cool concepts!
Interesting stuff !
Awesome tech.
interesting and a design to be taken seriously
Interesting info. thx. for the video.
Great content as always 👍 100% agree with the other comments regarding the new voiceover. It now sounds like a marketing video! If your unhappy/self conscious with your own voice over go back and take a look at the earliest videos from the other big content creators. They were all a bit rough and ready and the star and got better as time goes on.
Your work is good! Thank you for this info! I love it!
Thank you so much!
I like the new voice over
I got very curious for a while and then you mentioned the voice over.
Your personal voice makes this channel real. And there is nothing wrong with your voice.
Take care and keep it going ✌️
Thank you so much 😀
Fascinating 👍
Amazing stuff
Wonderful advancements. Respect ✊
This is extremely interesting
Great informative. Please continue.
LOVE The amazing wing tip rotor that becomes like the eagle's wingtip flight feathers... !!!
Excellent stuff bro
As someone that likes to think I'm up to date in this stuff, his was suprisingly informative and new.
Good job
Really informative. I've subscribed.
Muy Interesante!
Superb engineering!
As a human, I almost failed the Turing test on this one. Great technology, both presented and used for the voice-over - but I prefer your natural voice :)
Great video. Lots of diverse technology. Please look into the pros and cons of electric jets and propellers, regarding de-icing, and high-altitude/thin air propulsion. Thank you!
Thanks for the tips!
Multiple propulsors mounted in front of tilting wings provide many advantages.
Thank you for sharing this thoughtful video, my friend. 👍🏻🇺🇸🦅
I fit to be very interesting.
WOW!! exciting future for airfoils(so many applications)
They are!
first video of yours i ever saw, and the voice was like wtf thats kinda weird but ill keep watching lol
Prefer your voice, it identifies you & your channel from others, it's good practice & adds confidence to speak beyond RUclips. (You could always upload same vid with multiple voice overs or languages to test response although being authentic & yourself speaks louder than any complaints form others)
Looking forward to the next vid, lots of usefu infol & insights, thanks.
So nice of you
I encountered very similar wing tip vortice suppression in The Design of the Aeroplane by Darrol Stinton.
A proposal looking similar to a birds wing having 7 slots at the tips
I knew warped/morphed wings would soon come back in fashion. It makes so much sense with today's tech.
Yet many don't realise that the very earliest (half-foil) monoplanes used a crude form of 'warping wing' as control surfaces.
I especially love the 'folding tip-rotor', a concept along the lines of something I've been working on recently, a hybrid inspired by the V-22 'Osprey', the VWG- MRCA 'Tornado' & GD F-111, the U2 spy plane and the two ficticious - 'Samson' HL aircraft (Avatar) and the 'Cheyenne' - Rapid Deployment Drop Ship (Aliens).
.
My design incorporating a three tilt-rotor system like the Osprey, but with a pair of fwd wing-tip mounted rotors, in a slotted aerodynamic motor nacelle - so slotted to allow for 'variable swept wings' to be incorporated. The main rotors would have three folding prop blades (as often used in model gliders) that when not in use, would self-locate and collapse the blades streamlined to their propulsion nacelles (nested) in axis of thrust, when in forward flight to reduce drag. Folding outer wing sections capable of various degrees of aspect ratio; fully folded for VTO&SL to give the main rotors maximum downwash effect/lift. Partially open (swept wing) for fast decent and manourablilty at high speeds (main rotor blades nested or providing extra forward thrust). Fully extended for full aspect-ration to maintain lift at low speed/power in glide mode and at high altitude soaring (fwd rotors nested).
.
The design incorporates a third ducted tail rotor with contra-rotating blades controlled by microprocessor also liked to the 'Y-H' configuration stabilator/rudder actuators/surfaces. This ducted tail rotor is axial to the fuselage and can by rotated through ~100 deg inline to the axis of the fuselage, to either - horizontally act as a vertical take-off 'aft thruster' (in concert with the two fwd wing rotors), or slightly tilted aft (linked with the fwd rotors) for slow rearwards motion when hovering/manouvring, then rotated forward in line with the fuselage to give foward thrust as a 'pusher' with varying/increasing wing aspect ratios. The proc-controlled contra-rotating blades controlling yaw and course direction regarless of rotor orientation, synchronised with rudder/stabilators.
But these wing tip folding rotors give me food for thought... And don't they look like the wing-tip feathers of a large bird of prey?
I wonder why the shelved the idea..? What were the problems they encountered, if any?
Fantastic ideas. Thanks for sharing
Why jobo wing tip rotor is discontinued?
As a hang glider pilot, when I went sailing in the mid 90's I had the idea of making a sail fully double surfaced with the ability to morph its geometry to change the airfoil from one side to the other as illustrated in this video 6:26. Too bad no one listened. :D
Very nice video. I don't know what the old voiceover sounds like, but this one sounds very natural. Is it automated? If so, then that's very impressive. Good research, good info!
Is the new voice part of an april fools prank? I liked the old voice!
Lovely picture
I like hearing the author's real voice talking about important innovations. Continuous surfaces with variable geometry will become normalised once we see a breakthrough design in commercial use. Military long range and E-VTOL drones may be the obvious first use and may have already happened. Simple electric autogyros are already showing promise and await battery tech to get just a little bit lighter. With variable aero they could become highly effective commercial aircraft.
Flexible wing control stuff goes back to the Wright brothers. "Special" materials may not be necessary for light aircraft- elastic plastics and fabrics may already exist which may be suitable.
All of these technologies are old enough that they have been proven impractical due to expense, complexity, lack of durability, or all three. The ones you mentioned as being abandoned or discontinued are proof, but I'm fairly sure all of them are no longer being actively developed.
I strongly prefer the real human voice -- this robotic one is so bad that it distracts from the (as always) excellent content.
One more petty dork here. I love this voiceover even though the old one was fine this is better.
Wow
I prefer the current voice...Interesting and informative site...Keep up the good work and current voice...Thank you
Ok. Thanks
Yeah, the new voice is a bit more robotic than I’d prefer, although I could see the appeal for some-it does seem to fit solidly within the focus-tested advertising-voice-over pitch and timbre ranges.
There are interesting concepts that produce thrust without jets or props.
Morphing and transformation is key to making a flying craft versital to flight travel methods, even Phase formation, unlike the term "stage," *phase* converting, as engines, going from propeller, to jet afterburn, to ramjet & eventually rockets and energy perpulsions, from ground to solar orbit travels & beyond.
Original voice over is perfect.
2:20 what is going on with the heat exchanger?
I have a rough draft now for a new design, it will be a biplane, with wings at the rear, and a rudder between 2 electric plasma jets, with forward and reverse thrust, the goal is to create an STOL - SSTO capable of light speed.
The size and shape of the fuselage will need to be contained within a gravity well, wings and all for light speed to be reached.
It will run on tokamaks, and possibly if necessary, combustion also.
Estimated time to complete : 2 months
I find the new voice easier to listen to. That is because it is clearer and more like voices that I am use to. I didn't mind the old one, but I had to listen more carefully to be sure I heard everything.
I agree - I much prefer the original voice.
I prefer your voice, but great content, thanks
can't biomimicry help with this variable wing shape problem to provide optimum lift and flight control by copying birds wings and underlying tensegrity model of muscles+bones+tendons ?
This voice over sounds like Jeremy Clarkson with an overdose of Prozac...
we are back in 1980 with that voice and that form of talk. thank you for your atention ahhahaaahaha
In this vein, yuo may have a look to US patent US3563496 to Daniel Zuck, who made an extensive use of the freewing concept for the main wing, the tail, and the rotor blades.
The Wright brothers first airplane used warp wing technology to control the aircraft.
Very interesting! The problem is that advanced technologies take a lot of time to be validated both as technological solutions, and economic ways in solving those problems.
I vote for the original natural voice :)
New voice over debuts on 01/04. Hopefully it is in fact a joke
Technology is good. For Local flights much more complex wings are not needed, cause speed and distance is short. Folding wings would work better then flexible wings. Thanks
I like that voice
Super cool new voice but it's not your voice. You may feel your voice is accented or imperfect BUT it's YOU.. All the hard work and amazing research and knowledge is in your voice. For me I'd rather hear your voice.
new to your channel

Work on over coming gravity waves!
We desperately need a breakthrough technology in batteries
Hello Folks, While I sort out my "W" and "V", I will try to publish the videos with a more professionally done voice over. Hope you will be able to understand this more clearly. Thanks
Yours was fine, Better than drone voice. Always great content though
That's fine bro just keep on practicing. Keep it up 🆙
Your narration was fine, as long as you're not one that pronounces 'Th' as 'F', that one makes my eye twitch whenever I hear it.
Don't waste money on narration, just focus on trying to game the youtube algorithm and establishing a unified, aesthetic branding.
A better mic was all I think it was needed, your videos are amazing man!
I definitely preferred your voice
previous voice was fine. Was it natural?
Can't you get steven hawking to do your bounce over?
If not get a speak and spell. :)
Imaginations
Fantastic content! But I much prefer your own voice to this robot.
Thank you! Noted
The new voice over machine sounds very good, but a little rushed. It doesn’t leave enough silence at the end of sentences.
I was on the margins of being able to clearly understand your original voice so I don’t mind either way.
I understand that not everyone uses English as their first language so understanding someone with a strong accent can be too difficult.
how come the narroation has changed , cant watch this ,i could mute it. ok thanks
I used a professional narrator this time. I thought people would appreciate it.
I think it is very much appreciated it!
yeah bro we love india!
Great, but check the pronunciation of Piasecki - very different - more like Piah-setz-key.
Noted!
@@ElectricAviation Big thanks. I hope this helped.
👍
I'd be curious why designers go to such length to avoid a simple tilting wing / tiltwing?
There is this Dufour VTOL tech from Swiss which seems to work.
For motors on the wing and the wing can turn vertical for VTOL. In flight it is a normal efficient airplane wing.
PS: I guess it's because only electric motors and advancing material sciences makes this now possible. Still wondering why not more electric aircrafts are designing tiltwings now.
Почему бы механические закрылки не использовать?
I prefer this voice.
No offense meant. As a non English native speaker, Indian or similar asiatic accents are among the hardest to understand Just to give an example, Pr Anantha Suresh from Bangalore has some very interesting lectures on Variational Methods in Mechanics and Design on RUclips, but it takes me a tremendous amount of concentration to understand his English. However, I have had some very hard experiences with some Texan, Scottish, even some BAe Filton engineers.
The new voice sounds caricaturally English but is far more understandable to my ears, to the price of losing your enthusiasm and personality. Cornelian choice.
Nevertheless, I appreciate the rich content of your videos. There was lacking some technically knowlegeable content on RUclips. I feel your aeronautical culture is so vast you may consider enlarging the scope of your videos beyond electric aviation.
HULK SMASH FOR FLEX-FOIL PANTS...!!!
new voice is better lowkey sounds cooler
I prefer this voice-over, but that's my personal bias: I spent more time in my life around media and people talking with this current accent, so I understand better.
The content is great, as always!
One of the plane names 'Piasecki' is Polish name, should be pronanced very differently :-)
Voice: so overproduced and without any soul.
Content: awesome, didn't know about some of those projects.
Flexsys: not sure if a continuous wing shape is better per se. E.g. drag can be beneficial for descent and on the lower wing when rolling to help compensate adverse yaw.
Also, not even sure that flex tape thing would even reduce drag instead of increasing. Strongly depends on the state of the flow. Might possibly lead to delamination bubbles.
Well said!
