I don't think you need to change your thrust angle. The reason you have down trim on the vanes is because it's still way tail heavy. The plane should glide forward with no thrust if balanced correctly. The thrust vectoring should only be to alter direction, not to trim an out of balance aircraft. Awesome start though. If I were you, I'd look at sliding the fan units forward an inch if possible and perhaps change the shape of the nose slightly to give the ability to bring the battery forward a couple inches further. Great work!
The stall characteristics led me to believe the same! My only question would be, for a vehicle that's designed to only operate under very high speed conditions, to include landing, maybe the rulebook is a bit different
I think the thrust angle does need to change (point down more at the rear) as he said it was almost ballooning with increasing throttle so maybe needs that as well as some CG change to balance out the on and off power characteristics.

In 2005 I bought my nephew a small RC model of an SR-71. It also had no control surfaces. Lift was generated by airspeed and yaw by adjusting the thrust of the two fan motors. We had tons of fun flying that thing around so I can appreciate your enthusiasm. Well done!
On my experimental machines I place the battery or a tungsten weight on a slider with mechanical linkage coupled with elevator or trim knob to have inflight CG control.. also you may try counter rotating fans if you're not currently. Great work on this concept prototype!

This was teriffic! Thrilling! Your enthusiasm was contagious and uplifting. Such a positive attitude toward your goal that you did not know for sure would work. After wading through pure shit this morning on YT, I found a bit of gold. Thank you from an old gent that used to make balsawood models more than a half a century ago.
Atta Boy, Good work, milestone. Thx. Not even an RC aircraft guy at all here, but when I saw the vid title stating "No Control Surfaces" I had to watch. Can certainly appreciate the first aircraft to fly without them.
Nice work, but this model clearly is controlled using thrust vectoring. A pretty inefficient way of thrust vectoring. Probably way better to move the exhaust as a whole instead of breaking the exhaust airflow into two parts.
This is awesome! Pushing the boundaries. I know very little about powered aerodynamics, I’m just a paraglider pilot, but this is awesome. And, your enthusiasm is also awesome. Best of luck. 👍
Wow man another impressive video. Your enthusiasm is infectious brother. It is awesome that when the crash happens you just keep going. Keep up the great work man. I have downloaded a couple of your designs have completed yet. Doing a stackable generator now. Again awesome bother.
Suggeation Dual tailfins at 10 to 15 deg outward cant. Mount on engine ducts to be in line with thrust. Commentor suggested engines forward about 1 inch which would assist in setting CG. Again, just suggestions. But otherwise a fantastic job. 👍👍 Last thought - your NGAD is cliser to a powered lifting body. The thrust vector flight control provides the directional x-y-z axis motion. As such it will always have a lift aspect which will make for slower speed landings tricky nose high attitude approach. While not necessarily a stall to landing, you have to compensate for the lift designed into the aircraft. As you witnessed when flying it, the a/c was quick to climb as the air flowed over the airframe and wings. You might want to view a bunch of SR71 vids showing the nose high landing approach. Bleeding off speed to neutralize the design's natural lift tendancy will certainly take some practice.
I flew RC before gyros was available. Wonder how many young ones can really fly a model without all the high tech assist. There is no skill in sitting back and let the electronics do the flying while you direct the direction and height.
Basically this is equivalent of balancing a broom upright on your hand. The vectored thrust is like your hand moving to and fro to keep the broom head from ripping sideways. The further forward the C of G from the vectored thrust the easier it is to balance. The faster it goes means the faster the thrust over the vectoring surfaces thus providing better control authority. The stall landing is as a result of much of the lift is being generated by thrust alone, similar in concept to the STOL characteristics of the Vought XF5U.
Brilliant Design And Execution Of Physics My Brother! The Skunk Works NGAD Fighter Has Been Flying For Several Years And You've Figured Out A Multi Million Dollar Enterprise For Yourself! ✌️
Congratulations. Great design is more than the sum of parts. Well done and TY for sharing your thrust vectoring aircraft success with us. I can imagine this leading to some really fun toys and surely other kinds of airborne progress. 👍
Excellent job! On the control surfaces topic, Boeing X-53 & Grumman X-29, both had very unconventional methods of flight controls. Definitely do not stop experimenting!!
It's thrust vectored on both sides of the roll axis, so it's got pitch and roll. Toss is some motor differential and yaw will be minimal. When I did CG on designs like that, I always had to include the nose shape as part of the wing. All in all, it's a good prototype and a fun watch. A+
That was pretty amazing so the weight or the battery and further you put it forward it kept the nose down and it’s just controlled by thrust that was amazing to watch and learn a lot. Thank you for sharing that video. and I think you are a very high energy individual and I know you can make this work..💯%💪👍👍🇺🇸🇺🇸🇺🇸
I am going to make a suggestion about the fans from my experience making flow straighteners that might help with thrust vectoring or might not. When your air channel has an 8 to one aspect ratio, unchanged, meaning a straight tube, you get solid, stable, laminar flow. Laminar flow may get you more authority with less throttle. I don't know if you have room for it, but I would experiment with moving the ducted fans as far forward as possible and then being very uncreative with the channel leading up to your control vanes. I bet you could chase that stall throttle down to 25%, maybe lower, if your exit ait was very non-turbulent.
Hans Solo and Luke would have "soloed" in this simple future perfect air frame...(SR-71 baby) nice job with everything you printed!! I am old school, but love the vectoring theory as you have proved my thinking for years. Now... I wanna build a 2 place sand buggy for true ground affect!! Yes... lets do the future!!!
True but slightly in his defence I think he was thinking of those as thrust vectoring, setting up a nozzle on that little thing would be pretty tricky. That said it was a bit of a click bait title.
@@brettm.s.1169 that shape seems to respond very strongly to changes in the centre of gravity, it may be possible to steer with just X and y movements on a table pulled by bands or something. Two relatively heavy gyroscopes to change pitch, roll and yaw may work and would be sort of in theme with the thrust vectoring
Really enjoyed your adventure flying airplane. I don’t know much about planes because I’ve never flew anything like what you’re doing, but I realize that the reason you’re having such great success is the guys in the aerospace industry when they design this SR one spyplane decades ago they really know what the hell they were doing. So the vector controls that are built into your engine exhaust are being used on jet airplanes nowadays anyway but I’m glad you’re thrilled. It was a joy watching you and hearing your comments I gave you a thumbs up and can’t wait to see what you come up with in the near future with a new printer design 🎉😊.❤
This is basically what looks cool on paper and works on mini model, That's pretty dope. Though in terms of scaling this up, with the fuel introduce in turbo jet engine, you're just asking elevons to eat the hot exhaust gas. Also restricting tiny bit of thrust with the material in the way. It still looks cool for RC fans in this experiment though, but would be interesting to see an attempt with jet engine. Keep up the good experiment!
I have a bunch of rc planes I no longer fly (to windy where I live) and I just came across yer video. Very cool. Congrats on making it work and sharing with all of us. Again, very cool!
Well you just demonstrated something I've been thinking about for a couple years. The best way to maintain stealth while flying is to have (drum roll please🥁) _no control surfaces & use TVC instead._ Any time a control surface is deflected, stealth is compromised. With this design, the jet can maneuver without compromising stealth. The one thing I'd like to see is an NGAD that has TVC but also has control surfaces for things like landing and in particular dead-sticking in to land in case of engine failure. The trick is, you have the ability to de-couple the control surfaces from the FCS and then lock them down so they can't move until you unlock them and couple them back into the FCS. I dunno how LM is planning on doing the NGAD as far as the physics of flight control, but to me this right here is the way to go. Bruh. You just got another subscriber🛩️🤟. Maybe you oughtta send video of your flight tests to LM?

This is one of those “Duh” moments, when someone thinks of something relatively simple, but that no one has done before! I think you call it INGENUITY! Brilliant video buddy.🎉
The stoke in his voice when it flew. That's an awesome feeling. Great job and very awesome plane. The efficiency of using only thrust vectoring will be interesting to see refined.
It has control surfaces, but they only affect the flow from the fans. It won't stall, as in having flow over the top separate, stopping all lift. It might not have enough airflow to make enough lift to stay aloft, but it won't stall. It doesn't have only tiny wings, but a lifting fuselage body (going back to Burnelli and Junkers and others, (long before Northrop or the Hortens). From now on, all front-line high performance tactical planes will have lifting bodies, and not just for smooth shapes for stealth, but for increasing L/D and decreasing drag and for better range & payload. Sooner or later lifting body fuselage will work its way down into general aviation. See the '70s Boeing model 754 like a Burnelli lifting fuselage body with wings and tail. For a similar propeller driven lifting body / integral wing-body plane, see the '40s Eshelman, commonly known as the "flying flounder". One which did fly in similar planform see the '30s Moskalyev SAM-4 "Sigma" and the '40s jet or rocket powered RIM-1 and the SAM-9 test plane which flew well. Fit it with jets and thrust vectoring like this. Or with the internally pressurized airflow controls in most designs with out moving control surfaces. Of similar interest, see the '90s Wainfan "Facetmobile" light plane. (though he worked for a major aerospace /defense contractor, he knew nothing about the F-117 and if he had, he'd have been legally not allowed to make it.) It flew well, quick and efficient on low power, stall-proof. Another minimalist airframe wing/body plane which many would say shouldn't fly and certainly not as well as it does, the Rowe "UFO" light plane from Australia.
Wow, amazing! I don’t know the terms you’re using and to some it all makes sense but the little kid in this 57 year old body of mine is jumping up and down in excitement for you. Well done! 👍🏻👍🏻 👏🏻
Now for the VTOL version! I've been doing research into a silicon foam that would be useful for crashing rc aircraft. Right now any type of silicon foam is too heavy, but there's another material, a metal foam, which can be produced to provide a support network for the silicon foam that binds it's segments together. Silicon casting is done at room temperature, and the metal foam is made at around 1920F. If you'd like to try this yourself let me know.

Not sure how this got on my feed but I love it! Great job and following!
Awesome effort 100% proof of conception, with the deleting of control surfaces flight efficiency goes up, much longer flying times can be achieved 👍👏👏👏👏
That was an appropriate use of the word "epic". It will be interesting to find out which three-letter agency sends someone to visit you first. Thank you for showing us this. It's an amazing feat. I'm looking forward to learning more.
loved it !!! thank you for the upload, i flew for13years and loved the experimental aircrafts, still have Oshkosh on my bucket list. Goodluck my friend ......Marcus in west Texas
Program in some differential thrust for yaw control when you remove your v- stab. Good job!
Ohhh yeahhhhhhhhhh. That's how they do it. Duh. The sudden realisation, lol.
That was amazing! Now I want to build a bigger one with landing gear. Excellent flight!
Put a rudder on it, no rudder and landing do not mix. Bank to turn down low and wing into ground does not fly either.
@@chrisbraswell8864 tell that to the b2 pilots. Back in the 70's or so, pilot landed a b52 that lost the entire vertical tail surface.
I'm getting the joy from this fellas joy. I'm impressed as hell.
This was teriffic! Thrilling! Your enthusiasm was contagious and uplifting. Such a positive attitude toward your goal that you did not know for sure would work. After wading through pure shit this morning on YT, I found a bit of gold. Thank you from an old gent that used to make balsawood models more than a half a century ago.
Atta Boy, Good work, milestone. Thx. Not even an RC aircraft guy at all here, but when I saw the vid title stating "No Control Surfaces" I had to watch. Can certainly appreciate the first aircraft to fly without them.
The control surfaces are in the fan ducts.
Sure looked like it. It must have some kind of controls, and that is it. Engines off no control.
@@chrisbraswell8864 thrust vectoring
You are correct by the looks, it's basically an Elevon mix aircraft. They just happen to be in the ducts. And so a spurious title.
Nice work, but this model clearly is controlled using thrust vectoring. A pretty inefficient way of thrust vectoring. Probably way better to move the exhaust as a whole instead of breaking the exhaust airflow into two parts.
Makes sense
Your lack of despair after the first few failed launches is inspirational. Just revise, repair, retest. I love it.
This is awesome! Pushing the boundaries. I know very little about powered aerodynamics, I’m just a paraglider pilot, but this is awesome. And, your enthusiasm is also awesome. Best of luck. 👍
It’s beautiful!
Damn, but that’s an incredible bit of engineering. I’m hooked. I love creativity.
I’m printing the FA/XX right now 80mm scale seems good at 143 thank you for the good builds u put out.
Love the video and the real-time discovery process. Congratulations on sticking with your ideas! You did it.
Theres NO WAY that's goi...
NO. WAY!
That was awesome!
Amazing stuff! Love people who do things like this. They are the true innovators who move humanity forward. Very impressed. Keep up the good work.
Wow man another impressive video. Your enthusiasm is infectious brother. It is awesome that when the crash happens you just keep going. Keep up the great work man. I have downloaded a couple of your designs have completed yet. Doing a stackable generator now. Again awesome bother.
As a developing FPV pilot by hobby and Aerospace Engineer by trade, loved this video, loved the enthusiasm.
Videos are fantastic. You’re doing a beautiful job. Keep up the great work.
Suggeation
Dual tailfins at 10 to 15 deg outward cant. Mount on engine ducts to be in line with thrust.
Commentor suggested engines forward about 1 inch which would assist in setting CG.
Again, just suggestions. But otherwise a fantastic job. 👍👍
Last thought - your NGAD is cliser to a powered lifting body. The thrust vector flight control provides the directional x-y-z axis motion. As such it will always have a lift aspect which will make for slower speed landings tricky nose high attitude approach. While not necessarily a stall to landing, you have to compensate for the lift designed into the aircraft. As you witnessed when flying it, the a/c was quick to climb as the air flowed over the airframe and wings. You might want to view a bunch of SR71 vids showing the nose high landing approach. Bleeding off speed to neutralize the design's natural lift tendancy will certainly take some practice.
Very cool concept and congrats on the successful test flight! The stability without some form of gyro assist is impressive!
I flew RC before gyros was available. Wonder how many young ones can really fly a model without all the high tech assist. There is no skill in sitting back and let the electronics do the flying while you direct the direction and height.
Basically this is equivalent of balancing a broom upright on your hand. The vectored thrust is like your hand moving to and fro to keep the broom head from ripping sideways. The further forward the C of G from the vectored thrust the easier it is to balance. The faster it goes means the faster the thrust over the vectoring surfaces thus providing better control authority. The stall landing is as a result of much of the lift is being generated by thrust alone, similar in concept to the STOL characteristics of the Vought XF5U.
Skunk works already knows about him.
As do the Chinese.
I love your process of discovery.
It might need an air brake to land.
Brilliant Design And Execution Of Physics My Brother! The Skunk Works NGAD Fighter Has Been Flying For Several Years And You've Figured Out A Multi Million Dollar Enterprise For Yourself! ✌️
Well now the cats out of the bag, I am gonna post mine! 😁👍👍🇺🇸
Congratulations. Great design is more than the sum of parts. Well done and TY for sharing your thrust vectoring aircraft success with us. I can imagine this leading to some really fun toys and surely other kinds of airborne progress. 👍
Hey, super cool my dude, please keep sharing, awesome work!
Excellent job! On the control surfaces topic, Boeing X-53 & Grumman X-29, both had very unconventional methods of flight controls. Definitely do not stop experimenting!!
i am pretty sure the moving surfaces count as control sufaces?
only when there is power
He mentioned "traditional control surfaces"
you could do the same thing with vectored nozzles. I think that is what he is getting at.
But it’s for thrust outcome not lift or say Flaps down, he is using manipulation of thrust exhaust for Flight only, wow
Thrust vectoring IS control surface, dude!
It's thrust vectored on both sides of the roll axis, so it's got pitch and roll. Toss is some motor differential and yaw will be minimal. When I did CG on designs like that, I always had to include the nose shape as part of the wing. All in all, it's a good prototype and a fun watch. A+
Ignore the haters
Fun project and impressive how quickly you got it working so well and with stability
No haters here. Just pointing out that when he says “zero control surfaces, guys!” he’s mistaken.
This is fantastic! Congrats! I honestly would have expected it to need a gyro, but the fact it is stable enough without one is impressive.
The algorithm loves you today. I saw the view counter jump 2K halfway through the video.
110k views now. What was it 16 hours ago?
One month later, were at 880k views for those interested.
That was pretty amazing so the weight or the battery and further you put it forward it kept the nose down and it’s just controlled by thrust that was amazing to watch and learn a lot. Thank you for sharing that video. and I think you are a very high energy individual and I know you can make this work..💯%💪👍👍🇺🇸🇺🇸🇺🇸
I am going to make a suggestion about the fans from my experience making flow straighteners that might help with thrust vectoring or might not.
When your air channel has an 8 to one aspect ratio, unchanged, meaning a straight tube, you get solid, stable, laminar flow.
Laminar flow may get you more authority with less throttle.
I don't know if you have room for it, but I would experiment with moving the ducted fans as far forward as possible and then being very uncreative with the channel leading up to your control vanes.
I bet you could chase that stall throttle down to 25%, maybe lower, if your exit ait was very non-turbulent.
Great idea. I have about 1.5l inches of space.
Hans Solo and Luke would have "soloed" in this simple future perfect air frame...(SR-71 baby) nice job with everything you printed!! I am old school, but love the vectoring theory as you have proved my thinking for years. Now... I wanna build a 2 place sand buggy for true ground affect!! Yes... lets do the future!!!
There's no control surfaces! Except for these control surfaces.
True but slightly in his defence I think he was thinking of those as thrust vectoring, setting up a nozzle on that little thing would be pretty tricky.
That said it was a bit of a click bait title.
It’s surged my imagination to think of how NO control surfaces could be possible. Shift in COG, subtle drag, shape shifting body ?
Every Drag surface is a Control surface.
At 25:15 The front section would add so much lift because its greater dimension is in the direction of travel.
@@brettm.s.1169 that shape seems to respond very strongly to changes in the centre of gravity, it may be possible to steer with just X and y movements on a table pulled by bands or something.
Two relatively heavy gyroscopes to change pitch, roll and yaw may work and would be sort of in theme with the thrust vectoring
I am not an RC enthusiast, but that is an interesting design and it flies! Respect!
Well, technically, the thrust vectoring is a type of elevon. Cool design, though!
Really enjoyed your adventure flying airplane. I don’t know much about planes because I’ve never flew anything like what you’re doing, but I realize that the reason you’re having such great success is the guys in the aerospace industry when they design this SR one spyplane decades ago they really know what the hell they were doing. So the vector controls that are built into your engine exhaust are being used on jet airplanes nowadays anyway but I’m glad you’re thrilled. It was a joy watching you and hearing your comments I gave you a thumbs up and can’t wait to see what you come up with in the near future with a new printer design 🎉😊.❤
This is basically what looks cool on paper and works on mini model, That's pretty dope.
Though in terms of scaling this up, with the fuel introduce in turbo jet engine, you're just asking elevons to eat the hot exhaust gas.
Also restricting tiny bit of thrust with the material in the way. It still looks cool for RC fans in this experiment though, but would be interesting to see an attempt with jet engine.
Keep up the good experiment!
I used fabric to make a door hinge for a secret compartment to hold my cordless hole puncher in my headboard.
I like your build.
You need a launcher so you don't have to throw them. Also need counter rotating fans.
Totally this ^^ As soon as I heard him mention the torque and saw the asymmetric trim the first thing I thought was contra rotating fans.
@@taviss2775 It's how I run my twin fan rigs CCW on left CW on the right.
CONGRATULATIONS M8 First time on seeing your work EXCELLENT. From the UK.
CELER ET AUDAX
NGL. This design is a regression into Air Hogs toy category. I prefer more control surfaces like a RUDDER, not less.
I have a bunch of rc planes I no longer fly (to windy where I live) and I just came across yer video. Very cool. Congrats on making it work and sharing with all of us. Again, very cool!
Well you just demonstrated something I've been thinking about for a couple years. The best way to maintain stealth while flying is to have (drum roll please🥁) _no control surfaces & use TVC instead._ Any time a control surface is deflected, stealth is compromised. With this design, the jet can maneuver without compromising stealth.
The one thing I'd like to see is an NGAD that has TVC but also has control surfaces for things like landing and in particular dead-sticking in to land in case of engine failure. The trick is, you have the ability to de-couple the control surfaces from the FCS and then lock them down so they can't move until you unlock them and couple them back into the FCS.
I dunno how LM is planning on doing the NGAD as far as the physics of flight control, but to me this right here is the way to go.
Bruh. You just got another subscriber🛩️🤟. Maybe you oughtta send video of your flight tests to LM?
To eliminate all control surfaces you would need to have adjustable nozzles off the fans to direct the thrust.
This is absolutely brilliant! So exciting to get it in the air like that after it looking hopeless. Well done!
Truly amazing and inspiring!!! Great job, man!!!👍🏻👍🏻👍🏻👍🏻👍🏻
Just watched this whilst having my Sunday breakfast (Manchester UK). Brilliant vlog by a young guy with an Awesome talent. Be nice to see the next Airframe in production. Onwards and Upwards.
SO EPIC😂🤣😂😁😁Its so mangled ..., and its flying!!🏁🏁🏁🏁🏁Congrats.. well done young Skywalker! You made an old guy, contraption model builder Smile. I was so into stuff like that in the 60s. We would make all kinda kool stuff. Ended up building HodRods from scratch , Follow your Dreams!!!🤙🤙🔧🛠️🔧🙏🙏🙏Be blessed.
This is one of those “Duh” moments, when someone thinks of something relatively simple, but that no one has done before!
I think you call it INGENUITY! Brilliant video buddy.🎉
An amazing accomplishment, keep up the good work man!
Dude that is epic! Well done on the design, it looks awesome!
came up on my startpage, now i am hooked! can't wait to see the progress. Good Job
The stoke in his voice when it flew. That's an awesome feeling. Great job and very awesome plane. The efficiency of using only thrust vectoring will be interesting to see refined.
It has control surfaces, but they only affect the flow from the fans.
It won't stall, as in having flow over the top separate, stopping all lift.
It might not have enough airflow to make enough lift to stay aloft, but it won't stall.
It doesn't have only tiny wings, but a lifting fuselage body (going back to Burnelli and Junkers and others, (long before Northrop or the Hortens).
From now on, all front-line high performance tactical planes will have lifting bodies, and not just for smooth shapes for stealth, but for increasing L/D and decreasing drag and for better range & payload.
Sooner or later lifting body fuselage will work its way down into general aviation. See the '70s Boeing model 754 like a Burnelli lifting fuselage body with wings and tail.
For a similar propeller driven lifting body / integral wing-body plane, see the '40s Eshelman, commonly known as the "flying flounder".
One which did fly in similar planform see the '30s Moskalyev SAM-4 "Sigma" and the '40s jet or rocket powered RIM-1 and the SAM-9 test plane which flew well.
Fit it with jets and thrust vectoring like this. Or with the internally pressurized airflow controls in most designs with out moving control surfaces.
Of similar interest, see the '90s Wainfan "Facetmobile" light plane.
(though he worked for a major aerospace
/defense contractor, he knew nothing about the F-117 and if he had, he'd have been legally not allowed to make it.)
It flew well, quick and efficient on low power, stall-proof.
Another minimalist airframe wing/body plane which many would say shouldn't fly and certainly not as well as it does, the Rowe "UFO" light plane from Australia.
Wow, amazing! I don’t know the terms you’re using and to some it all makes sense but the little kid in this 57 year old body of mine is jumping up and down in excitement for you. Well done! 👍🏻👍🏻 👏🏻
Now for the VTOL version! I've been doing research into a silicon foam that would be useful for crashing rc aircraft. Right now any type of silicon foam is too heavy, but there's another material, a metal foam, which can be produced to provide a support network for the silicon foam that binds it's segments together. Silicon casting is done at room temperature, and the metal foam is made at around 1920F. If you'd like to try this yourself let me know.
Wow, So awesome. That is a beautiful plane if you can even call it that. Jamming Jet!❣️
Thinking out the box is cool, but building a dream and seeing it to fruition is creation. Quite brilliant 👏 🎉
