They showed testing and trialing, did it all with the full understanding of what could go wrong, yet the fun police have to pipe up about it.
I'm not sure if the authorities are just making a statement out of formality or if they really are interested in busting these guys.
Looks like a bit of a lark, would be fun. As long as you trust your mate doing the piloting
They're d!cks who knew it is illegal.
Lets cancel the rules? Hardly. Given the meteoric rise in them we need more rules, not less.
Top marks for the know-how needed to build a drone that can lift an adult male though. Any bloke who builds stuff is impressed.

Thanks for posting kiterperson, great fun to read and watch..
You were right kiterboy about the nanna fun police. Lots of them here on seabreeze as well
Fan of the tech, fan of their build quality , not into bragging about breaking the law that they well knew, then sooking about the consequences.
If that makes me a nanna then yeah OK.

Not sure any laws were actually broken? Maybe the one about "...over or above people at any time or height" although presumably that doesn't include the user.
^^^ yeah above a person
plus any UAV / RPA above a certain loadlimit (its big, not just a little recreational)
then any aircraft that carries a person- like experimentals and such obviously require permits, you can't just build a one man helicopter and just go for it.
^^^^^^oh and you missed the fish they caught was not of legal size so should have been returned to the water.
Mr. Darwin says you can
Surely it cant be real,?
I don't think it is. I think its a fake.
Looking at the video I would think that the drone is undersized for carrying a person.

Definitely possible. I do a lot of electric RC flying and the size of the motors, props, and lipo batteries in the video would be capable of lifting the weight. The controls are cheap and easy too, just a little trial and error in the tuning to make it stable.

Really? I just assumed that lifting 70kgs or so might be beyond these. I guess batteries have come a long way, but no doubt flight time wouldn't be that long.

They had 12 motor/prop sets. Here's a YouTube of a guy getting 60kg thrust from a single brushless outrunner motor and lipo battery. You'll see at the end that he has a reading of 300 amps as the maximum current drawn from the lipo battery. Sounds like a lot, and it is, but it's no big deal either. The batteries I use in my RC helis can deliver 300 amps at 50 volts, which is exactly what is used in the setup in the video I've posted below. Sure you can't do it for long, but they had 12 sets, so a lot less thrust and therefore less current required for each one, giving longer flight time. Probably a few minutes possible, maybe more depending how many battery packs they had strapped into that thing. For the drone, they would have used a setup with much smaller motors that was capable of delivering around 10-15kg thrust per motor, which is chicken feed.
Wow. I am surprised.
How would I go about making my own 'windsurfing-assist' setup? It would be cool to go sailing without all the hassle of needing wind, and I can ditch the sail too . It might be good for those days when you need a little pump to get planing but otherwise can keep sailing.
I am curious about how you get so much power out of such tiny motors. If you can get a few Kw out of such a tiny motor, how come industrial motors have to be so big?
They say that regulation kills innovation. It was annoying to hear that the aviation authorities wanted to have a go at these dudes. Imagine if this type of trick was encouraged rather than stamped out, what could be possible.
I just grew up expecting to live in the Jetsons type world by now.
^^^ That is why Australia is no longer the clever the country, we're just full of bureaucrats trying to justify being alive.

Yep, it's unbelievable. On my medium size heli, I'm getting 2.5kW out of a motor about the size of one of those little bottles of Yakult. I think the reason that it's possible is two fold....firstly, excellent air flow for cooling, and secondly it's only for a few minutes, not continuous for hours. And believe me, after 3 or 4 minutes of flying like this....your brain is fried more than the motor or battery.
You want to see the power of only a single one of these motors in action...watch this video. Note he uses low head speed at first, then cranks up the power at 2:27, so if you only watch a little bit, watch from 2:27 to 3:30. This weighs only 5kg, but look how he throws it around. It uses the same 50V 300A lipo I've been talking about. Around the 2:50 mark he's teleporting the 5kg from one spot to another...there are some serious instantaneous power draws then.
And yes, if it hits him, he's dead. Those blades will slice right to the bone instantly and bleed him out through multiple arteries in a couple of minutes. (Happens to a few guys every year.)
I remember as a primary school kid looking through some sort of RC magazines at the local library, reading articles about normal petrol(?) powered planes, electric ones, and even compressed gas powered ones.
I guess the electric ones had nicads, but I am sure the flight time was still quite short.
The amount of power available by lithium seems incredible in comparison.
Harrow - awesome
That's the one thing I hate about drones, 99% of people don't know how insanely difficult that heli 3D stuff is as drones do it all for you and are so easy. Proper heli's are indescribably hard to fly, let alone inverted and rapid changes in orientation that reverse all the controls repeatedly
Helies are soo hard .
After spending $ 800 for a beginners good one , I smashed my way through another $ 1000. In parts .
Thats just trying to get a small semi controlled hover ,which never happened .
The last time I used it , it came at my face . Luckily I turned and the blades hit the back of my shoulder . No injuries
I sold the Satan's child for $200 including many spares.
It's OK , I'm alive , not sure about the new owner
ps : those skills in that vid are insane !

they do encourage it ; in Australia you can build an aircraft under CASA's Experimental rules. you can build it from whatever you like as long as it is for education or recreation.
when it is ready to fly you need to have it registered and inspected by an Approved Person, an AP . these are usually engineers associated with clubs/organisations , some charge for the inspection some do it for free.
CASA won't stop you from flying your homebuilt but will put limitations on where you can fly it .
i just found this , seems it was built in Korea ;

About 15 years back, I got a nitromethanol* buggy because the current battery tech seemed feeble and didn't last long.
Unfortunately, probably spend as much time tuning the bloody nitro engine or trying to get it to start as you would charging batteries :(
But when they go they, they really freakin' go! Got sick of trying to get it to run and got an electric monster truck.
Last Xmas the kids showed an interest in RC so I hauled out the electric monster truck and got that running (on NiMH batteries) and got a little monster truck on LiPO.
HUGE difference in power and run time. And the price of LiPO batteries isn't horrific so you can have bunch. One lasts long enough that I start to worry what the children are up to...
* nitro is the usual fuel for RC it seems but you can get gas engines, usually in big scale like 1:5, like this one:

Do you think there's a bit of tech in there that's running the propellor at the back.... I mean 'tail rotor' (thanks Google) ? I suspect that the rest is manual, but trying to keep that thing steady would be crazy.
The movements seem too sudden for a someone to control it, and its the sort of thing that computers and g-sensors would be good at. You could probably even have some default mapping that changed the pitch or speed at the back to compensate for changes to the pitch or speed at the front.
Either way, its an impressive demonstration.

Yes, there is a solid state MEMS gyro that holds the tail steady, and moves it in response to control inputs. In fact that is a flybarless model that actually uses gyro stabilisation in all 3 axes. I can do about half the stuff in the video, but I need a football field. It's freaking unbelievable he can do that in such a small space and only a couple of centimeters from the ground.
Super awesome that anyone can buy an electric power system on the internet powerful enough to fly a person fairly economically.

Three tips.. put the hours in on a high quality RC computer simulator (I prefer Aerofly by Ikarus), use a flybarless heli with a reputable MEMS gyro, and set up your heli perfectly. (Jeweller's scales to balance blades perfect, digital pitch gauge, etc.) Start with very mild settings in your transmitter and low rates in the flybarless controller.
Oh yeah.. spend some money on a strong, fast digital tail servo.

The great thing is that you can build something like that for a few thousand dollars using hobby parts brought on the internet.
The downside, there's a lot of simple things that can go wrong and you will fall like a rock. It's not like a plane or heli where you can glide to the ground or do an auto-rotation landing.
