Brilliant - great to see another totally original idea taking shape! Before winter comes along requesting another multi-cam scenic flight in the chAIR, I am sure many of us miss seeing that wonderful machine in action!
I was also taught to set tail rotor gains high until oscillation when flying helicopters. But then certain new manoeuvers can cause it to oscillate. You would have to keep dialing it down until no maneuvers caused oscillation.
The Hiller VZ-1 Pawnee coax flying platform was apparently very easy to fly using just your feet- it became much harder if you held on to the handle bars . So if you lose all your flight controllers just stand up !!
Finally, Welcome back! It is so good to see that you have posted (and such an interesting one) a new video, I missed your inventiveness! I hope you are keeping safe and well. Tony from Western Australia 🇦🇺
Awesome project! (as usual) I love how you walk us through the problem solving and show the crashes. Just curious: Any plans for a DIY Sherp update? I'd love to see you take it on some rocks and off-road. Push the limits of those tires.
This is great! I've always wondered how well this Coax-Setup would work with 4 small quadcopter-like rotors on the outside. They have a lot of control, since they're nice far out from the center and they can act as a failsafe for the main rotor and possibly hover the vehicle at max power.
Perhaps lower prop has to throttle a bit higher, which gives slight gyroscopic procession, so when stopping laterally, the pendulum effect causes slight procession due to higher bottom inertial and prop speed. Just a guess though. Incredible build though, great design, I really like it.
I believe the characteristic you refer to as "ringing" may be a gyroscopic precession force. You may find a reduced effect by 1) Using propellers with more blades, 4 or 5 blade for example 2) Moving the propellers closer together 3) Making absolutely certain that the two motors/propellers are rotating at the same speed at all times.
Nice work. I'd put a shroud around it as you are losing a lot of power and control as air is pushed out the sides. I'd also put the weight on the bottom with the control vanes on the top.
looks like a dart it will always orient itself to point into the wind, even if the surfaces above and below the cg are the same size the just is a lot less resistance in that direction, than being hit from the side equal drag from all sides would probably be preferable, but where would the propellers draw air from...
It would be nice if you did a video explaining the downsides of your quadcopter design. Talking about the stress on the metal. I saw some news or forum where you had briefly mentioned that.
What if you made it more efficient and controllable by combining the rotor blades which provide the lift with the adjustable vanes which control direction? It would be a real breakthrough.... Oh wait, that's a helicopter.
How many lbs of thrust are you getting with the dual rotor setup? Can you stack motors and get double the thrust? I’m also planning on building a hang on to or sit under type prop bar using brushless Tiger motors U15 ll 80kw motor. Which is rated for 80lbs thrust a piece. I want to use for houseboat to fly from houseboat to shore.
Just the other day i was like ”what happened to the genious inventor on youtube?”
Your projects are always amazing 😁
Tomatoes are disgusting.
I'm coming for you
yeah
And yours allways funny to watch.
I am his student in Sweden on a technical School.
He is back :-)
Wohoooo, finally a new video!
I hoped to see your flying machine everywhere by now. Emergency escapes from tower blocks or joy riding over the grand canyon.
Good to see you have been busy on a new project. A very interesting EVTOL machine.

That brain of yours is awesome. Modern day Nikola Tesla.

It’s interesting to watch the design in process. Thanks for taking us along!

@@davidbrosten1921 Well, I’m sure you are learning more than I ever did at mine. Good for you.
@@JimsEquipmentShed Yeah! He is really cool and used to show us experiments.
@@davidbrosten1921 There are some people that teach, and done people that do.
It’s a rare person that does both.
Another great video, thank you!
Finally, Welcome back!
It is so good to see that you have posted (and such an interesting one) a new video,
I missed your inventiveness!

YES! You just made my day ! ...Onwards and Upwards !
Awesome project! (as usual)

your username always delivers 110% on its promise
love all your projects, please do more videos, including failed designs!
Great to see you again, and great work as always!
Beautiful craft, love watching your videos they are very inspiring.
ДОЛГО ЖДАЛ ВАШЕГО ПОЯВЛЕНИЯ. ВЫ НАСТОЯЩИЙ ИЗОБРЕТАТЕЛЬ!
welcome back miss u buddy
Great to see you back
Love your projects! awesome job 👍
Great to see another upload!! Thank you very much for sharing.
Ah... at last, a new video of indeed an amazing project.

You are my Hero!
Who need wind tunnel when you have part of your old hover chair.... :D
Awesome
Trevligt! Saknat dina projektuppdateringar.
What so ever. So Lovely job.
Great Job Again!
In my rusty old Swedish... vi har saknat dig.
Dont fret, that was perfect.
That is so cool!

Good to hear from you.
Amazing !!
ur backkkk yasss
Wouldn't all the problems with authority be solved by increasing area of the little control fins on bottom?
I'm very curious to see what would happen if the COG was way below the control surfaces .
Pendulum fallacy
and no fast flow
Very interesting!
Nice work. I'd put a shroud around it as you are losing a lot of power and control as air is pushed out the sides. I'd also put the weight on the bottom with the control vanes on the top.
It reminds me of the the WASP (Williams Aerial Systems Platform)
Reminds me of the old Hiller Flying Platform
en.m.wikipedia.org/wiki/Hiller_VZ-1_Pawnee
looks like a dart
it will always orient itself to point into the wind, even if the surfaces above and below the cg are the same size
the just is a lot less resistance in that direction, than being hit from the side
equal drag from all sides would probably be preferable, but where would the propellers draw air from...
When you used a ladder to hold your motors in the 2 meter ring, this is exactly of someone has to go ahead with experiments..
It would be nice if you did a video explaining the downsides of your quadcopter design. Talking about the stress on the metal. I saw some news or forum where you had briefly mentioned that.
Long time no see! Glad to see you! :)ъ

The I term in your pid loop seems saturated, your control inputs should reset it. Amazing project
Sweet
What happened dude. I miss your videos a lot! 😇
Så häftig!
Yes yes you Still alive!
the mythical ADP.
Hello there! Long time no see
What fun.
Reminds me of the original concept of the helicopter
I feel like you need to tilt those stators tword the incoming air rotation a bit. It looks like it would cause some turbulence right now
Can you cut the power to the motors if it's heading for a crash (to protect the props)?
2 x 15kw brushless motors , you could be riding this thing to work in no time (-;
Nice
Awesome! Do you plan to attach 3 of them together in a triangle at some point?
I've missed comment from this channel.
What if you made it more efficient and controllable by combining the rotor blades which provide the lift with the adjustable vanes which control direction? It would be a real breakthrough....
Oh wait, that's a helicopter.
It’d be just like a commercially available drone. 🚁
nice
Are you on FaceBook Dude?... I would love to share an idea with you!..
You will love it and feel compelled to build it haha.
looks like "vortex ring" , en.wikipedia.org/wiki/Vortex_ring_state#Detection_and_correction
Hi mate could you please tech me how you converted the pwn output to run the throttle servos on your petrol drone
why are there servos for each control surface? are they moving somehow in a predicted angle?
How many lbs of thrust are you getting with the dual rotor setup? Can you stack motors and get double the thrust? I’m also planning on building a hang on to or sit under type prop bar using brushless Tiger motors U15 ll 80kw motor. Which is rated for 80lbs thrust a piece.

Why the remote physical limits? Cant you just adjust the curves in its software?
chAIR 2.0?
Salut c'est quand tu sors ta grosse machine volante
