How Does This Fly With Only 1 Wing? 

Same here. The extent of my Swedish after a couple trips to Sweden is "Tak tak". (I don't think that I interacted with any native Swedes that didn't speak English...)

My Swedish is limited to the goods in the Ikea catalog 😂😂

Completely agree

translations are fine

Same here. Love the difference in speech and it doesn't detract from the info at all

100% agree!

Now those "landings" on the other hand... 🤣

Imagine enjoying the playground then seeing that thing coming for your head!

Pioneering work for future A380-size boomerangy airliner?😅😅😅

wow

Ello

Now let’s try to find a genius who can give basic directional control. Maybe with some gyro magic? Since it’s rotating an upward force might translate into a pitch or yaw if timed properly?

I have made monocopters with directional control, using a magnetometer (digital compass sensor). A gyro is usually too slow, since most gyros have a maximum measurable angular velocity of 2000 degrees per second, which translates to only 5.6 rotations per second. So unless your monocopter rotates very slowly a gyro can't keep up.

An old Popular mechanics magazine has a design that supposedly works perfectly

You saved me from 5 minutes of agony

It was painful to watch!

See, that's what I'm talkin' about! Like a "master juggler" keeping all the balls in the air

Agreed!

Yes, and another function is to set the wing's pitch angle (as well as the prop's pitch angle). The weight basically makes the vehicle strongly prefer to align its "plane" perpendicular to the spin axis. At that point, you can set the wing and prop's pitch angle relative to the weight pole.

@@IsaacKuo yep good point

So adding a servo to move the weight stick up and down, could be used to control the wing angle of attack.

Yeah, just don't say the same word in dutch lol

His English is better than some of my English friends 😂

It's really untrue that the wing will spiral off if the thrust vector is not pointed straight down. In fact, it's impossible for the thrust vector to point straight down due to drag. The wing has no propeller to counteract drag, so its thrust vector will always point "backwards" compared to its motion. The propeller is there to prevent drag from slowing down the spin rate, but it's pointed in the opposite direction so this doesn't "straighten" the thrust vector downward. It does the opposite, making the thrust vector even further away from straight down. Nevertheless, monocopters work and the fact that the thrust vector does not point straight down simply is not a problem. Why not? Because the vehicle is spinning. That means that the thrust vector sweeps out a cone, and the overall effect is an average thrust vector that points straight down.

@@IsaacKuo "monocopter"? Should be “monopter”, one wing. But drag is resistance to horizontal motion. The monopter is supposed to hover, isn’t it?

that's also a wonderful example of doppler effect! so cool!

yes! it reminded me of the old Batman scene transition sound effect! that or one of the old time sifi radio shows.. maybe "X - 1"? OR the old "lost in space" shows.

Have you seen his hovercraft? At least the wing on this is PLA/Depron 😅

Haha I had to go thru the comments & see if someone else noticed & then got to that part of the video 😂
