No, you can't stabilize a drone with only two motors and no control surfaces.. Three is the minimum.

IPhones weigh ~ 100 grams drones with propellers that size weigh ~10 grams
swatz
Hmm some of those run at 30k rpm for helicopters. I have a few at the house, maybe I can test. *ponders*
JonWallace1985
It’s not purely about speed, a propeller going too fast creates turbulence and makes the airfoil less efficient.
Hammertulski
This lesson brought to me by Capsela. Bubble boat won't move? Step down the propeller speed! For your health.
NoFuxToGive
+1 for Capsela, back when there were toys to make you think.
JackieTreehornProductions
Air cavitation is a thing too - it would spin faster than the air could be taken in.
Leithoa
Yeah but you need tip speed around 200mph
Would you agree that's a 3" diameter blade? Then it's a 9.4" circumference which at 30,000 rpm = 282,000" per min = 267mph.
No, I wouldn't. That looks like a normal sized phone, all of which are under 3" across. So the props are <2.5, I'd wager under 2". 30krpm is
5)batteries can't output the 10's of amps needed to get the power from more powerful motors.
4)around 100 grams unless you spend loads of money on a higher KV motor. You can't use more battery, cause they get heavy fast & cell
3) most phones are at least 100g, +external battery +ESC+motors we're outside the thrust of them. A pair of rotors this small only puts out
2)hard to get without a pretty big battery. You need 11V or so on most motors, so tip speed isn't the reason this is fake. Weight is.

MisterBriightsiide
I was thinking it was stuck to a fishing line attached to an actual drone maybe?
Paragon19
Yeah, that would be the most convincing way to do it, plus it would be easier to use two lines to prevent spinning.
CyanideBreathMint
There is a kit out there using 4 rotors of similar size to make a phone a drone. I was too sceptical to buy it though. But maybe 2 can 1/2
cyno01
That sounds like a good way to fuck the hell out of your phone battery.
drewbixcube127
Not a chance. The phome battery isn't made to dump power that fast. Umong other things.
Xenolith166
Not just using the phone battery.
skwh
if it used any other battery, it would absolutely be too heavy for two rotors to keep afloat
What about a pair of watch batteries?
2/2 generate sufficient lift to keep the weight afloat.
weaselodoom
But with only 2 there is no way it is staying so stable
Idk, could be fake, but modern brushless motors are strong enough where 2 could possibly maintain the weight of a modern mobile.
LonelyHotline
Is not about strength but surface area of the blades of the rotors
ForgivingCat
Those rotors are 2-3 times larger and the motors too.
https://odditymall.com/phone-drone-ethos
captainpoopyshoe
Also, 2 rotors can't hover stably without another degree of freedom e.g. pivoting motors. Almost definitely fake.
Remove almost. Add definitely.
CrookedCherryBlossom
Definitely definitely fake
ComicSansHumor
Maybe two can be stable if there's a reaction control wheel on the other side. But yeah, probably fake.
gallifreyanegnineer
I think they probably could if you have the two props spinning opposite directions.
Google the rocket pendulum fallacy, it's a somewhat unintuitive
flyelectro8888
That would not work since it would be impossible to tune 'm just right. Also, the voltage drop after a couple of seconds would see it go ...
... down very soon. Then you get windshear and (lower) ground effect constantly influencing the lift. You would need a flight controller ...
... like in, say, a drone to have any chanche of keeping it in the air. I had a micro drone with 4 motors basically that size and it ...
Can you explain this a little more? What is another degree of rotation and why is it required to keep it stable?
Try standing on one heel. That's 1. Try two. You need 3 points of contact with the ground to keep stable without moving. Similar here.
One thing I forgot to add: a controlled tilting propeller would change things. e.g: modern helicopters. https://youtu.be/xtZpcUj_wqQ
These look like standard quadcopter props, though, so still likely fake.
Some people don't want to understand stability, I guess.
Thanks. This helps.
Usstiberiusk
That’s because we’re topheavy. The phone is bottomheavy, like hanging a panel from a string at two points. It’s not perfect but it’s stable.
But it's a propeller, not a balloon. It doesn't push upward, but in whichever direction it's pointing...
Google the rocket pendulum fallacy
PMPB
Rocket pendulum fallacy.
That's exactly how it's hanging, though. By a string. Not propellers.
UncleVinny
Then the batteries die and your phone just drops 5 feet to the ground.
tutwankamon

Gif21
If only phones had some way of telling how much battery life was left!
It doesn't appear to be plugged into the phone for power.
Fair enough, I would try and pull from the phone,but not sure if you can pull off the USB from all or any phones.
Yup. They make personal fans to connect to the iPhone port to draw power from. But clearly this thing isn't real.
You might not be able to pull enough power needed for propellers that will actually hold the phone up.
captainsmitty
So just include a simple algorithm in the app that any less than a certain percentage of batt. life refuses to use the props. Easy solution.

Right, the phone won't let the camera open under a certain percentage. But how would this thing draw power from the phone if it were real?
