Dude your weekend was more interesting than my entire life
The Subaru Withoutback!
Your uploads are perfect timing for lunch time on Saturdays here in the UK :)
It's lunch time in india as well.
9pm in Aus. Perfect time

Next project: autonomous dynamic speed soaring.
Yeah, that's exactly what I thought as well :)
This would work pretty good. But not with a foam plane. Actually this could become the new record setter
@@peterzingler6221 I reckon it would be very tricky for an autopilot get the turn at the right angle in the right place. Waypoints might do it but it wouldn't be optimum.
Nice flying. That reminds me of the old days with my Olympic glider, 11 ft wing span, our club used to fly out at a sod farm, miles of flat land and tons of thermals in the hot summer. Your flight reminded me of a couple times I got into a huge thermal, the aircraft pointing almost straight down, and still climbing, and once disappeared into the high fluffy clouds for a moment. The only thing i could do while I could still see it was pick a direction into what wind there was and with full down, keep going until I finally flew out of the thermal. After passing through a couple more violent thermals on the way down, finally was able to land it safely. What a scary experience. Those were the days of our home made high starts with about 300 metres of line and about 75 feet of rubber elastic on the end with a small parachute at the end which hooked onto the glider. I love the little motors today and the folding props. No more setting up high starts, as we had no motors just the old gas engines which we would never put on a glider, that was a sin. lol.. Happy Flying
1:30 I so recognize that "losing interest already" look from any friend I've ever tried to get into this stuff…
Same😂
I’m glad i’m not the only one who experiences ardupilots “BAD AHRS” consistently.
i get it all the time irl and even in the simulator of mission planner. wtf
Morgan yeah it’s quite annoying, I like to have it talk to me when running a mission but it just repeats that over and over and its stuck through all the updates that i’ve gotten over the years.
Probably the most interesting channel I found on TH-cam in all these years.
"found a random guy with a boat"
forgets to mention the random chicks...
and the covid pandemic
@@marianoramos598 yeah but bikini bottoms make a perfect mask :)
Lol
lol u think these nerds even talked to them? doubt it
@@r3d0c I think he has a girlfriend? He may even be married
Congrats on achieving autonomous soaring, very cool
Lol tl;dr
I don't understand why you didn't program a figure-8 so it would never turn in towards the hill if you are sloping.
Did you have much experience flying line of sight on the slope before getting into autonomouse flying?
have you stopped paragliding? that looks like an amazing place to do some ridge soaring on PG also. edit: just got to the part of the video where you were flying the second plane... goddamn those are some fat thermals! 🤤
This gave me an idea for a project: an autonomous "thermal finder buddy". You on your PG seeking thermals and the airplane scouting ahead for the best ones :P It's like having a pet vulture, without the feeding and the crapping part :P
Cool ideal. Thermals move, so you'd have to be following the plane. Then that adds the possibility of getting hit by your own plane. On the ground, it's ouch. But having a plane hit the paraglider chute :-(
@@PeXnb area banning would work wouldn't it?
Bruh, thatd be some BUMPY air for a paraglider. Dry air likes to come up in big bubbles. Hed have to wait for the evening for the thermals to mellow out but yeah, seems like a good spot otherwise hahaha
@@SupernovaSpence bumpy is goooood! turbulence is life :D
I'm going to do something similar but instead chase it with RC airplanes with my buddies at my AMA Field
Bring a badminton net with you to fly into in these situations.
Yep nets work well in rocky terrain
I was just about to suggest a net to capture
This is a really nice solution I think
As a glider pilot I find this super interesting!
If you want to increase you efficiency try to plan your route along the strongest part of the lift - you set it to fly in a circle/rectangle meaning that in at least one direction it wasn't flying in the best part of the lift
Exactly, and from my experience that flight pattern wasn't anywhere near where I would expect the strongest lift, which of course would be close to the ridge line.
What about using the motor as a generator/air brake to recharge de battery?
I second this question. I noticed the propeller moving when the motor was dead so it'd be neat. I suspect trying to do this would steal too much momentum and you might stall but it'd be neat if you could do this with thermals.
Despite my complete lack of autonomous gliding knowledge, I think this sounds like a great idea!
This would not be very effective. The plane has such a low airspeed that setting up the motor to charge the battery would create an extremely insignificant amount of power generation for the time. In addition to this, the plane is not fully able to soar completely with thermals and needs to boost itself up more with the motor. Essentially it would produce almost no power but create more drag, thus the plane would more often need to use the motor to power itself higher.
I was wondering the same thing. It seems like you would be able to grab at least a bit of power if you used it to charge capacitor or something that didn't have much load and use that to then charge the battery. Im sure there are multiple reasons why this is wrong and wouldn't work but seems like a possible idea.
@@madeintexas3d442 The law of the conservation of energy would say otherwise.
Dude! Love your content. Wish I had more time to do what you do. Living vicariously through you!
Man that was a dicey launch at 2:55 - almost stepped on the wing of your other glider!
Oh hah I see later in the vid it wouldn't have mattered if you had :)
First time I watched a flyer who programs software & builds hardware. So cool!
I really enjoy these autonomous vlogs you do Dan, keep up the good work
Thank you for the consistent info,videos and data you give us on the Ardupilot and accessories you haveshown us I personally still enjoy your progress and efforts .....
Ever tried a catch-net landing? That rough ground must be tough on the planes especially with fast approaches.
I've seen a guy make one up out of fibreglass tent poles and a couple of thin bungee cargo nets for a car trunk strung really loose. 6'x6' piece of carpet underneath to absorb any bounce-back. Packed away very small
Your videos are fun to watch! Boats, planes, rovers, and always with some interesting twist to investigate! :)
When you’re smarter then your friends and they just leave... Nice vid!
I envy you man. Got the coolest toys and the knowledge to operate them! Never lose you passion
Gonna go slope soaring tmrw. Thanks for the motivation!
Love the chaotic energy of these friends.
If you give just enough throttle to get the folding prop out in the air stream, but not enough power to create any forward acceleration, it acts like a giant air brake, better than spoilers. Might have helped with that fast plane landing.
Better yet spin it backwards :)
@@iforce2d Do you have any vids coming up?
As always you guys are awesome doing some great stuff
This is looks so fun, piknik with friends and fly the beautiful plane. Really cool
Solar plane v4 next 👁️
Looks like a great adventure!
Great video Daniel, I enjoyed it very much. I like how you make your videos, considering I am not an expert, but it's so easy to understand what you do, why you do it, how you do it. Once again, great job, keep up the good work :))
Great video, keep them coming!
Love your videos! Keep up the great work!!
Having been both the tow boat and towed boat on more than one separate occasion each, it is always nice to find someone willing to help. Boats are a lot of fun and a PIA, all in one. And a hole in the water that you throw money into. Did I mention that they are fun, though? :-)
Really cool looking vid so far!
Sounds like a great time!!
Always learning and sharing!
Awesome vid love watching your stuff 🙂👍👍
Cool experiment man. Look forward to the next one.
Have you considered making all of your turns away from the slope? Essentially a figure 8 pattern instead of a oval. Making turns toward the slope can be problematic especially in higher winds.
@15:38 is one of the coolest sounding things I've ever heard 😁
I'm sure you've done the usual adjustments to the ASW 28, like tailplane incidence adjustment, as you've already cut down the tip winglets. I removed the winglets and increased the span to 3.1 mtrs, she floats nicely now. Oh, plus I increased the wing chord by about 15mm, by adding foam to the trailing edge. I used 3mm foam that I "pinched" all along one edge with a woodworking vice, using aluminium radiused counter edging to prevent biting into the foam.
Awesome shots from the mavic
Really enjoyed it, thanks!
What an awesome slope site!
Beautiful video and I love the edit !!
The majority of the information in your videos is way beyond my knowledge and understanding but for some reason I can't stop watching. Thanks for sharing!
Sincerely,
A new subscriber
Your ideas are awsome
You do the best stuff! Keep it up.
Enjoyed motorcycles for 30+ years before MS got to me - don't ride any longer. Wanna get into RC and learning all about it by watching all your videos. I greatly enjoy the straightforward, no-nonsense explanations. The only exception I can think of was the pumpkin pulse jet ... but you were a bit distracted from providing explanation while playing with a pumpkin-shaped mixture chamber!! lolol!! I even enjoy your friends' musical contributions! Seriously. I just listen to the lyrics and laugh along. You (and your friends!) provide such great content. And now I find out you're a fellow dirty dirtbiker like I used to be? Thank you SO MUCH!! 👍✌
woah
i love your autonomous bot vids
I REALLY love your videos
That's exactly the video I've been waiting for 😃 EDIT: Actually, no, I wanted to see the "long range" autonomous soaring in the desert.
great concept, well done
Those are some sweeeet blue leather dirt biking boots! wowee!
Bring several inflatable mattresses (with string to anchor them down) to bounce those fast planes off to slow them down with minimal impact. Deflate them when not needed.
Salut ho super tank you vidéo magnifique bravo
Great video. Thx
HI Daniel
thank you very much for this most interesting video.
I am involved in the same topic and could learn a lot from you of this issue!
That looks like a perfect paragliding spot :)
I think the "fun" would be programming ( in contrast to parameter setting) the autopilot to seek out Lift and slope soar in classic figure 8s.
Awesome flying, great video as usual.
Ideally, the turns should be made away from the slope, which implies in alternating right-hand and left-hand turns. If this cannot be directly programmed by Mission Planner, then perhaps a mission with more intermediate waypoints directing the glider to always turn away from the slope could do the trick.
glad to see logic making videos again
The idea with a piece of cloth on a stick is genius!!! Why didn't I think of that
Cool vid.
I used to fly my combat wings in Acton where Dynamic Soaring was invented. Those planes go like 250mph through inverted loops up and down the cliff and then use the energy to skyrocket themselves several hundred or thousand feet in the air. It's really a sight to be seen to go watch them do it in person. I was pissing everyone off smacking them in the heads with my combat wing at 60mph lol. I had to tie some serious weight on the nose just to get it to fly there. That spot in Acton is famous and crazy as hell. Worth a visit, man!
I love your vids, can you try to make the fastest possible plane/ jet you can
pile drive into the ground was fully accurate! I want an autonomous widebody soarer like that V tail, maybe a lifting widebody... : ))
Keep watching Ardusoar, there are some great improvements coming in, including better stall detection and recovery.
that was a gooooood landing.
Always amazing content! Is there a way to set waypoints for position but with just a min altitude? Would be interested to see where the albatros would end up left to its own devices.
Did anybody else catch the white Orb Flying bye 13:35. UFO???.. I don’t know but I always enjoy watching your videos 😀👍
Again really cool. :)
Nice post.. keep up the good work.
I was pondering something that uses weather info, elevation info from some sat info, and the telemetry from the rc glider to plan gliding paths. Nasa MAY have done some work on this, that and this work seems similar.

Great video keep up
14:40 Dam, at that rate of ascent you wont get the plane back in a long time unless you do something about it
that subaru is awesome.
Looks like it's time to try this with the solar plane next!
You can change the maximum autopilot descent rate which may the issue in the strong lift
Please do more of these videos
I was out paragliding the same week at the same spot. Too bad I didn't see you there! I've seen that you paraglide at the point, maybe I'll run into you one day since I'm up there most days.
14:00 Like the Hawaii method (foldable/copllapsable chairs in truck bed), but even more goofy.
Don't forget that on a slope, if the wind is blowing at right-angles to the slope, the lift can work up to many times the height of the slope although it will become progressively weaker with altitude .
This guy is living my best life
Pretty cool info dude, judging from the inconsistent and light wind as well as how the planes were going up and down I'd say (from a paraglider pilot's perspective) most of that was thermals :)
Just remember that the airframe stress will significantly increase with higher speed. If the AP completely ignore the speed, it might overspeed and when you hit turbulences rip your airframe or your attitude control surfaces apart.
Maybe add a speed brake to the plane, if the AP supports that 🤔
10:30 "You could stand on these wings and they wouldn't break in half: they are so beefy and heavy..." crackle, splinter "...or, not." Daniel, you like to push the envelope. I guess that's what makes your videos so entertaining.
It was painful to watch lmfao
I am ready for an updated thermal soaring video
A few interesting things about that kind of ridge/thermal conditions assuming there is a gentle breeze up the ridge:
- The strongest part of the ridge is just about 45 degrees out from the top of the ridge and rather close to it (a few hundred feet). The air compresses and wind has the strongest ridge lift at that point, not too far out from the ridge.
- A thermal can interfere with that ridge wind especially if they are strong thermals. It can even cause the wind to go a different direction on the ridge itself as you discovered. Once the thermal finishes it'll return to the standard wind direction.
- A ridge like that is likely to be a trigger point for thermals. The warm air can be blown along the ground until it hits something to trigger it, a ridge is perfect. You also have air heating up on the side of the ridge and creating it's own thermals.
- Thermals are usually stronger when combined with ridge lift.
I made a video about flying gliders along light ridges th-cam.com/video/hSYeg-l3-9g/w-d-xo.html
I believe spoilers would solve the issues you described. You need to reduce the lift.
Crow but then the flaps would need to work !
I would like to see more on solar plain power your other videos on solar are so cool
Thanks Man
im sure you get this alot but man u are one of the smartest dudes on youtube
Brilliant footage. Can you set a maximum altitude? It would be useful to use as an "energy buffer" for when later on it goes through areas / times with less lift.
Rolling tarp with velcro used as an unrollable landing way strip, add some velcro on the bottom of the planes.
Good video
This is cool. Im South of the Teanaway although my friends Ethan’s never showed up
very very nice
get a camera on the second glider and try some long range fpv flight
because he has good luck with long range fpv flight.
Coat your white glider's wings with black spray paint. So it can soar up higher altitudes. Heheheh
