IRL, I am a 42 year old electrical engineer. While watching your videos, I am a 12 year old kid trying to keep my jaw off the floor. You've created some really interesting projects and it is great seeing how far you've progressed over the years. Keep it up. The rap at the beginning was nerdy and wonderful too.
Great Video
Play some dead or alive to the video
I'm a 51 year old CS & EE. Makes me wish I had been so innovative in those earlier years. This guy is living a dream life, doing what you love.
Being a 12 year old my jaw is totally on the floor although with inspiration from rc test flight I have since purchased a ender 3 v2 and built a cnc router and I enjoy making rc planes and drones
"High-Quality Autonomous Ground Effect Vehicle" has been added to my spotify playlist
Fck that song haha
i need it
Best music
[Insert guy looking at smoking airpod here]
It's unreal
Everything about this project is soooooo impressive!
You two guys are absolute legends!
Yeah, this plane is Awesome!
the song most of all
That about sums it up! 👍
yes
For efficiency science: Ask the plane to maintain an altitude that's out of ground effect and compare energy consumption against maintaining an altitude that's in ground effect? That would give you a measure like "minimum energy required to maintain level flight", which is a pretty useful metric for a ground-effect vehicle. Even if you get different speeds out of that comparison, you could still make a useful claim about energy required to travel between two waypoints.
The faster you go, the more the drag. The difference in efficiency because of speed is very substantial, more so than the ground effect
@@gi295 which only makes it another part of the power consumption. If the plane reaches different speeds for the same "effort", then that's a base to start fine tuning the experiments. Start of with a maximum of parameters the same and measure overall consumption and speed (time between A and B), then tune parameters to achieve same speed (match the lowest of the two). Also, with such a small plane, I'm guessing it will be bouncing in and out of ground effect, which will have a slight effect on airspeed and drag too, so a variable consumption due to different drag is already happening within the same flight anyway.
I agree with Saul that this would be the best approach to determine efficiency gain from ground effect.
what would be even cooler: an extremum seeking controller, maybe as an extra layer feeding a setpoint to the lower level PID ontroller, which measures energy use in real time and chooses the most efficient altitude to fly at
another banger of a track, ground effect the album when?
Sick track for sure. One request. Add heavy bass, thats worth some public disturbance 🔊 🔊🔉🔉🔉🔊
Collaboration.?
never thought the word "ardupilot" would be used in a song lmao. amazing
@John Thomas Bro jealousy all over you 😂. Why even take the time to comment? If you don't like it gtfo
@John Thomas Nobody cares
Would it be possible add a pressure sensor on the underside and top of the wings to measure what's going on? No idea if it would be useful, but you might be able to correlate it to efficiency, or factor it into the Ardupilot controller. Might just be a cool thing to see.
Actually it won't be that useful as it would be hard to set it to a value. But that's a nice suggestion.
I think it would be cool to see when the pressure semi stabilizes and ground effect is achieved
@@ApacheFPV yep
That's how an angle of attack indicator gets it's signals. It has to be calibrated one time in flight at zero g, if I remember how I calibrated my RV7
It is fine if the ground is flat. But with waves it is pretty hard to determinate what is the best pressure in this small scale.
These autonomous vehicle videos are fantastic, keep it up!

Boring one trick pony
these songs slap harder and harder every time
lol true
Honestly prefer just the instrumental. End up muting it every time or skipping the time lapses
Three thoughts:
1. Awesome project, series, and music
2. Turning altitude problem: Are you rectifying the lidar altitude measurement with roll attitude? Maybe even dial in some additional compensation with roll to account for the lower wing too
3. Flying over waves: With the lidar pointing directly down, your system is reactive and not so proactive in handling disturbances in measured altitude; meaning, you measure a high wave, your controller pitches up, but you've already passed the wave. How about pointing the lidar forward at an angle to get a 'look-ahead' measurement? Better yet, mount the lidar as far forward as possible on a stick out the nose. The distance to cancel out phase delay of the wave/vehicle reaction would entirely be dependent on the length of the stick, or your total control bandwidth. Could be a fun problem to solve on video :)
I love your work, I might try your flight controller and autopilot code some day if I have a chance.
I was wondering if it would be possible to mount it to a gimbal of sorts. Waterproofing would be an issue though.
Or several LIDAR units across the wingspan? Average them out with bias towards the central one in order to reduce input noise.
Homie with the paddle board is the real mvp here.
Seriously cool project that has a ton of practical uses.
You're audio musical interludes are total cheese and absolutely based. Keep that shit up!!
Having a airframe that can fly efficiently both in and out of ground effect is a big deal! Being able to rise above rough water or ground obstacles and then drop back down into GF makes smaller GF vehicles much more practical.

Just finished watching Think Flights video and was eager to see your side… and then this pops up! This has to be my favourite project yet, can’t wait to see what’s in store for us!

Solar plane V3!
I have two things that I would love to see: 1. You could create a way for the vehicle to avoid obstacles using distance sensors where it can either fly around or over things(and perhaps even calculate whether it is on a collision course.
2. A way to control the speed in ground effect by allowing the auto-pilot to adjust the pitch and throttle.
Keep up the good work!!

Kavin didn't just design the Nano Goblin, but the regular Goblin, and before that the big 80 inch Graugans featured in COFPV videos. All of his planes are super efficient, and the EPP/Kevlar/thinned-Goop ones are practically indestructible.
That is a fantastic and beautiful vehicle, well done to all involved.
Maybe look into creating a Kalman filter to combine all of the sensor data into a smooth-but-safe target altitude
th-cam.com/video/jXP6YwH6o1ku/w-d-xo.htmlt5
I was thinking two sensors (nose and tail), average the readings, and filter the data to get a smoother curve and hopefully not attempt to change altitude between crests of waves.
hahaha I've been looking forward to another banger this hot new artist. Good work boys!
The song is solid contender for the European Song Contest 2022!
Have you considered positioning two lidar sensors, each at the wingtip? With this you could take average out of the two, and on turns use the sensors to prevent wing strikes. My knowledge on lidar is limited so I don't for certain whether it would work.
Actually it would work, but it's not necessary. He can also make a code to increase the altitude / lidar distance value when the aircraft is turning to avoid wing strikes.
when its turning the lidar measures the hypotenuse of a right triangle so based on the turn angle and the distance measured you can calculate the distance from the ground
I think it would be better to place one sensor at the tail or in the center, and one sensor at the nose, and it should be at an angle of about 45 degrees forward. So it can tell the plane if a big wave is approaching. If it's not angled, then it would detect a big wave too late and the plane will hit the wave.
What about flared wing tips? Upwards to run parallel to the ground/water level in turn. Forcing planes higher and sort of fight the roll with increasing pressure as it rotates into the ground effect. Might make turns wider but also might add another safety against turning into the water or ground.
When on ground effect, can turning with just rudder adjustment an option?
I forgot about this channel. Come back every couple years. Every time you’re so much further than you were. So impressive!
Nice videos, but I think this would be a good idea for the next video - An RC sailboat!
You can just use servos to control it and you won't need bulky batteries for the propulsion.
yes.
something like "saildrone"
As it would need very small batteries for the sailboat, he can use solar panels for the recharging so it would have infinite range.
@@arnavpawar256 would an integrated solar panel in a rigid sail be feasible in that scenario or would the light deflection angle limit its ability to output a constant voltage?
@@jamesfieweger8648 you could prabably have flexible solar panels on the sail, which might charge with enough heel due to the wind?
Just another heads up - your style of editing and using footage is magic, my friend. I really enjoy when you post.
Thanks for blowing the spider off, and not killing it!
I'm always amazed seeing the hardwork you do on that videos :) keep donig it, it's awesome
I have been watching your videos for years, and I still can find nothing more relaxing than this.
This is awesome. Seeing you get the lidar on the water made me think of “dynamic soaring “. Sorta combine this project with another going for efficient flight.
You always have great ideas and execution.
This is my second rctestflight video, I respect the amount of time you put into your videos.
Dude! Music is NEXT LEVEL! In all seriousness, your content is top notch! Appreciate you and your crew!
This is my new favorite TH-cam channel. Keep being awesome dude. I love what you're doing.
Impressive! Friend of mine recently did a drone that would hold its position using an optical flow sensor and I remember how hard it was to get the control loop fine tuned. Can't even imagine how tedious that must've been for this much more dynamic system!
I'm so proud of my home town Seattle! These videos are great and oh BTW just some awesome music production on top of it all. This is my favorite kind of entertainment straight up.
Those batteries amaze me, powering the plane, control surfaces, transmit video, use GPS.... amazing. Thanks for this video. I wasn't even aware that Ground Effect planes could fly so high.
The fact that the breadcrumb trail is an A-6 intruder silhouette is a nice touch
You really really outdid yourself. Bravo! And I love the music and lyrics!
Man, I just discovered TF and binged his vids last week. Now the rctestflight vid is out. Sweet.
best footage so far! legitimately amazing shots in the later half of the video
Wow, what a beautiful background you have there with that snow-covered mountain!
This is exactly the type of RC plane I could get into. ROV/Autonomy and ground effect efficiency are fascinating combinations. Wish there was a turn key or easier starter point for beginners.
Such an amazing project
th-cam.com/video/jXP6YwH6o1ku/w-d-xo.htmlt4
Your videos are just getting better and better! I look forward to every upload!
one of the best parts of these videos is seeing all those random people you meet like the paddle boarder guy or the guy that took you on his boat
I watch this channel for both the tech and the scenery in equal amounts.
Some absolutely epic footage!
As others have said, this is an awesome project. And the "ground effect" music.. A super nice touch and I love it!
BRAVO!! I’ve been waiting with great anticipation for this video, and you guys certainly did not disappoint! Hell Yeah Man!! 😃❤️👍
Wow, Daniel, this project has been quite a journey and it's really evolved into something with huge potential. It so interesting to see which of your ideas develop way past the proof of concept stage and make it to this level. Also, at this point, I'm always expecting/hoping they include some Truck Daddy jams (who's on vocals this time, Seb?). Great content all around! Well done! Please keep it up!
I was absolutely mesmerized by this video
Your beats truly make these great videos exceptional
Everything you do is just so cool man
i don’t know what’s more epic. the plane or the self written soundtrack 👍🏼
These videos are always fun to watch because I live in seattle.
Wow… this is beautiful. The video and the music dropped my anxiety in minutes🥲 I’ve even put this in my favourites for any future needed chill sessions👌🏼😊
I come for the autonomous vehicles and stay for the songs!
I love the take-off shots, showing the rippling water.
i have actually returned back to watch the video for the second time, so epic this project is! Great job!
This channel has been consistently putting out some of the best projects I have seen for years.

@@Hitycooking Moving up and out of the third world with the internet. Respect the hustle.
Love the song you guys made! Thumbs up
Future airliner designer right here, ladies and gentlemen!!
I'm a simple person - I see rctestflight - I like and share
that plane flies as smooth as BUTTER! Love it!
One of the best projects yet!
Really awesome vid mate!
Great video as always. Great work.
Outstanding work Daniel! On the topic of analyzing efficiency: You could integrate the power over time to get energy, and the speed to get distance. Keeping separate integrals for each mode, in-ground vs. out-of-ground effect. The ratio of total energy to total distance would then represent how far the plane could go for a given amount of energy for each mode. This should account for the nonlinearity in the relationship between speed and power. Keep the great videos coming!
That song is a banger and a good narrative device.
Awesome video and sound track, great job.
Great videos! It's cool to see where you are and having been there myself! I live in Michigan but visited friends near Seattle and we ate right down the road at Salty's in August!!
Love how you guys went from an Alexeyev style Ekranoplan to a Bartini styled GEV as it gets better and better. Shows the design priority changing.

This is one of the most enjoyed video i have ever seen, and i dont know why
So rad! I hope you can find some nice snowy fields to try it over this winter!
Great song at the beginning and really nice pictures
Another great video, thanks! What I would really love is a video about the technical stuff, how you tuned the algorithms and some cool graphs and mathlab data 😀
I really like your musical segments when they are short.
Super cool, it needs a way to sense for obstacles and make adjustments to it's preprogrammed course.
Gotta make a playlist of these bangers
Visually Brilliant . Project Outstanding. Song Absolutely Shocking.
That shot of Seattle around 18 minutes was amazing
Great video, I love the song in the beginning
Love the Song with the flight montage!
Your honestly killing me with these songs 😂
That was really cool. Keep up the awesome projects!
The self made music is so bad, I love it, dont change it. It is fun, actually puts a smile on my face
16:20, loved blocking up and playing around with that creek just behind you, probably still just as fun
Came here for the plane, stayed for the sick beats 🔥
VERY impressive....and the song puts a huge smile on my face 😁😂
Hey guys... what a great project. Kudos.
Man, this was really an incredible video. I liked it a lot, and I can't imagine the amount of work that must have gone into it. I can't wait to see what you do next.
Speaking of what you do next, how about an autonomous submarine of some kind? That could make for some interesting footage. Also, since I love your autonomous boat content so much, how about an autonomous sailboat? I would love to see what you do with it! I love all your work, great stuff all around.
Everyone that likes this channel will like Think Flight. Great planes, experiments and videos.
This collab was incredible
Outstanding work. Respect!
I’ve said it before but the songs keep getting better haha
Super cool plane and video, loved the collaboration and following the Think Flight channel too
Amazing man keep up the great work
love it, tech stuff i get mostly but the VT is really great
If I get one wish I wish for more videos from you guys. All videos are so interesting.
Loved the video - the song was great! You ought to do more like that in your vids!
Still as cool as ever, nice one Daniel.
Not sure how this video showed up in my feed but glad it. I live in seattle area also. Would be awesome to see these guys doing this in real life.
What a glorious video!! Bravo!
