Yuneec Coaxial Electric helicopter

Chinese Drone maker Yuneec has been testing a coaxial electric helicopter made with carbon fiber / affordablehelicopters

[@LK-pc4sq]

As a former sikorsky mechanic I am impressed. I would love to build my own small micro copter ;) Just need cheap land to do it.

[@sidim2841]

Can we work together to built this tiny heli....

[@Veldtian1]

Seek out the brothers Nolan, they have valuable knowledge you may find of interest in your quest, godspeed my friend. Now go!

[@Jurflip2]

In the days before turboshaft engines, coaxial and intermeshing rotor (Kaman) machines were an effective way to make maximal use of the limited power available from piston engines. When the powerful and light turboshaft engines arrived, the inefficient "penny farthing" designs, with tailrotor, became dominant. The advent of electrically powered helicopters, with their limited power capacity, could see a return to the more efficient designs.

[@manofsan]

I thought that Kaman machines were less efficient, due to their off-vertical slant. I've heard their rotorheads are simpler, though.

[@adamchurvis1]

@@manofsan No, not at all. If you are referring to the reduced downward thrust vector due to the slight angle of the blades, this is more than offset by the energy required to constantly flap the entire rotor blade of a non-Kaman design. The Kaman "Flaperons" are very lightweight and require no direct rotation of the rotor blade, opting instead to flex the blade through the aerodynamic force of the flaperon. Each mast has its own "swashplate" located underneath the mast rather than at the top like most do, and since the controls are manipulating only a slight force to move those lightweight flaperons the entire mechanism is significantly lighter weight than conventional controls. Another benefit to not losing all that energy through constantly rotating the rotor blades this way and that is that the entire rotor system on a Kamen lasts about as long as the airframe itself, rather than requiring regular replacement. The Kaman intermeshing rotor system is extremely energy efficient, helicopter-wise. The intermeshing rotor system was invented by a Nazi named Anton Flettner, who also designed the Rotor Ship (sailing ships with huge columnar rotors rather than fabric sails).

[@manofsan]

@@adamchurvis1 - which is the best Kaman-type intermeshing machine, in your opinion? Is it Kmax? Which is the most modern/advanced of these machines?

[@adamchurvis1]

@@manofsan Yes, I would vote for the K-MAX, which has all the advantages of the Flettner plus the many innovations Kaman invented. It is an incredibly versatile machine, and can be fitted as a UAV that can switch back and forth to Piloted Mode with the flip of a switch. Which Kaman is your favorite, and why?

[@manofsan]

@@adamchurvis1 - I don't know enough to have a favorite - but the Kmax does look impressive in its lifting capability.

[@marshal7102]

Now this is just Too Cool!!!!, I have a Yuneec Q500 plus drone and it is very great quality and a stable platform,,,,I know this will be great as well

a bit too small for me but thumbs up for starting new design of helicopter and not just converting helicopter to electricity.

[@0ohusseino077]

It's small and beautiful(:

good job

Does it fly?

[@rogervanleeuwen9989]

I like there products. Q5004K , Typhoon H.

[@user-qr4px4or1x]

Well, where is the flight? Do you know why they did not show it? Because the first separation from the ground for another six months to work. A fly - so it's generally very far, given what kind of pontoon, but not very competent country is engaged in the project :)

[@FPVREVIEWS]

Nice to see aviation in China going in a positive direction. In the US, the FAA has made sure that it cannot. At least someone is doing it.

[@Stambo59]

Sikorsky had an electric helicopter flying in 2010.

[@FPVREVIEWS]

true, i was referring to the home-built nature of manned flight at the forefront of technology,a nd developmental integration of it. I see you have one too!

[@paochunhsu9155]

Can I buy a copy of this product or just a kit form from you? What is the power rating of your e-copter and how much will it coast? Thanks. How do I contact you?

[@operarioanderson7981]

Congratulations! :)

[@jeffmullinix7916]

China new stealth helicopter that will do 385 MPH and can carry two Gatling guns on each side .

[@henry2008kim]

hum.. does it have rotor pitch change mechanism..? Looks like it doesnt...

[@DR-br5gb]

Yea I'm sure they forgot that part and being that you're the smartest person on the planet you caught it for them before they crashed and died so good job Sangyoooon you saved a life !!!

[@otphxerxotphxerx563]

wow this is excellent. One thing i noticed..the prop is kind of low, i think you should just place higher landing gear under the helicopter to lift it higher. and you should make a conventional version of this that is gas/petrol powered then i guess it would sell like crazy. especially if you have a kit version. and if it was a 2 seater , would be even better,

[@vancroft13]

That model already exists........... x10

[@marvinblankinchip2535]

OTPHxerx OTPHxerx ... Which prop?

[@imogenmog976]

I thought the point of an electric motor is its quietness...first theres music covering the engine noise then the sound is muted.

[@ShadeAkeley]

You do know that most of the noise you hear from a flying helicopter is the main rotor and tail rotor chopping up the air right ? You only really hear the engine distinctively when taking off and close to ground hovering

I am interested to this work

[@abdoaezah9804]

Slam alekom where can I buy all parts to make my own

[@aviasia2630]

You want this one? this is an electric helicopter. This is innovative, but no electric helicopters today can offer any meaningful flight duration and range. At least not yet. Do you have a helicopter license? If you just need a good performing & reliable kit helicopter, that I can help you. If you like, you can send me your email address and contact info to [e-mail]

[@rashmiranjannayak3251]

Its a good job but how long it can fly.

[@ashsmitty2244]

Rashmi Ranjan Nayak just remembered, the Wright brothers didn't fly that far. First attempt

[@rashmiranjannayak3251]

what its the energy storage Bank and power of the motor.

[@StellarBlue1]

I hear SYMA and EACHINE are collaborating on a new 4 passenger quadcopter. It will be powered by ten thousand 3.7 volt rechargeable batteries. (Batteries not included)

[@DutchRC]

I had not expected This from Yuneec.. Good to see they didn't go the multirotor route (as in quad or octa).. I am a bit disappointed they Are going the stick-control way with this though :(

[@dutchdrifter8740]

DutchRC Adventures Best to start out with low complexity and high reliability

[@DutchRC]

Sure.. it's not like 'we' are starting out with heli's now though..

[@dutchdrifter8740]

DutchRC Adventures They are. 😁

[@DutchRC]

Boring :P I want to see it auto fly after punching in de destinations location :) Yuneec has quite a bit of experience in that field

[@southpark4151]

Maximum range 10 metres, max flight time 30 seconds?

[@musicinspire1745]

Weill, it spun, but it didn't fly....

[@roidroid]

Why does it have a tail?

[@jackxie3311]

roidroid because it's helicopter,lol

[@NoahSpurrier]

+roidroid, Likely to settle yaw during forward flight for smoother flight rather than rely only on coaxial torque adjustments to counter undesired yaw. You don't want to the stabilization control system do all the work to have constantly bump minor adjustments to keep the thing straight.

[@Kimoto504]

Fixed pitch blades so no autorotation...
