I want to see a 5-15 kw RC Quad X copter..
Something with hobbyking parts..Biggest outrunners.. biggest rc controllers.... 30 or 50 inch props?


I wont be doing it.. But someone from here should.. Become like a LFP moment of some of his crazy ebikes lol
It's just insanely dangerous even if you know what your doing. Count me out.. ill stick with 10 inch props for now
 
10" props are fine. Just make it a quad² with 4 motors at each corner. That way might even end up safer, cheaper, and lighter. I agree, someone from ES needs to build and ride one. :mrgreen:

I remember seeing a video of a Chinese guy who made a multirotor with gas engines that he sat on and flew. I can't find it tho!
 
haha . yes.

Im keen to see a guy hovering around on a quadcopter.. you would need like 55 inch blades i reckon..
He would need to be light as.. and flight time would not be very long... I picture a couple of minutes..

but if i couild hover for 5-10 minutes that would be cool... :lol: :evil: :twisted: :evil:

All on a accelerometer/gyro :twisted: $30 hobbyking board

id go with thermistors in each motor with alarms programmed to reduce power if heat is a critical level.. but real time monitoring.
Moveable motors for redundancy.. if one prop / motor fails the copter can switch to tri-copter for a safer landing.
multiple flight controllers for back up.
prop covers or protectors..
comfy seat, maybe a gyro seat.
 
:idea: To lighten the load get a bunch of helium balloons to provide significant lift, which will also add stability. Then you can test it out with low power and greatly reduced risk before going all in.
 
Don't use Helium, it's a limited resource and we are running out of it since people keep wasting it on crap like balloons and parties. Use Hydrogen, we have plenty of that, we need to save Helium for useful things such as MRIs and research.
 
Well it's not a quadcopter, but this is pretty impressive. Very high power for its weight. Also a very short flight time...

I did see this...
they could of dropped her over water..


I wish it was being controller by one person...

So far the coolest thing i have seen is using EDF/Electric jet thruster pushing a surfboard/snowboard/parachute
 
How about something with 4 or 8 JM2 motors? Then you attach a hang gliding harness stuffed with Nanotechs and fly yourself around.

Here you are ..

Desired aircraft performance
• cruising speed of at least 54 kn (100 km/h)
• flight altitude of up to 6500 ft
• maximum take-off weight of 450 kg
• more than one hour flight time
• two persons side-by-side

But for more practical applications i suspect that heavy lifting might be done by "swarms" of synchronized, lower powered drones in order to allow for multiple redundancy and cheaper mass production of smaller components.

Amazing critters..

they are good those videos.. i have seen them some time ago..

they are all in a 3d environment tho..
I saw a regular quadcopter somewhere holding a Cup of water.. flying acrobatically .. kept a full glass...



They are talking on the news tonight about jet packs... that would be awesome..
 
Im thinking now.. my latest quadcopter at peak power does about 1.1- 1.2kw can lift a payload of 2kg at the most..

going by that ratio i would need like 50- 100kw to make a quad copter carry me

I know it would change alot if massive props are used.. maybe 100 inch +


far out wish i had more money.
 
A random quick ecalc calculation to lift 80kg+ 20 motors 23 inch props lol

54% throttle @ 80kg
74% throttle @ 110kg

imagine the gforce if you were a midget, See I cant wait for energy storage technology to get better.. I hope it keeps going and in 10 years this will be easier to do

yeah this is what i mean...

how crazy the flight could be.. you could free fall from the stratosphere and come in for a smooth landing.. do a flip on the way to work to get your blood pumping instead of drinking coffee or whatever.. you could be sitting in a gyro chair just like how you would use a Camera gimble to stabilize the footage..

I have been flying quadcopters for awhile.. and they can be the easiest to fly over planes-regular copters.. ect... ..you wont ever crash if you are careful.. and you can take it so slow to start with..


I feel like it all depends on the energy storage to make it good. more energy for humans will make things so much better.
we need batteries with 1000000s kwh worth of energy in a nice small package.
 
LFP and I built a 4+kW dodecacopter a couple years ago. It was capable of lifting about 10kg. This was one of the precursors to my RotorBits product line. Yes you can build this exact same 'copter from RotorBits and HobbyKing parts. I'm pretty sure you could build a man-carrying 'copter from RotorBits.
