Electric Powered Millennium Hang Glider
Вставка
- Опубліковано 6 чер 2015
- Twin electric motors from Hobby King power my hang glider for quiet vibration free soaring. The entire installation costs around $3,000, and most of that is the batteries.
Note: I incorrectly listed the battery pack as 7S in the video spec's. It's actually a 14S x 40AH pack made from 16 7S x 5AH cells. - Наука та технологія
This is an older video, but that is actually pretty doggone awesome. I love the recumbent seating. I would love to see this upgraded to 2020 standards and a full aerodynamic enclosure.
how could anyone dislike this? Wonderful glider. Wish they were still being made. Swift is very expensive.
I can only imagine what a full power takeoff length would be...
That landing distance was insanely short!
Great vid!
I fly R/C, and GA aircraft....this is awesome! If someone wants to fly but can't afford or stand the high costs with GA, thus definitely the ticket for sure.
Wonderful!
Its comfortable, more then any expensive shitcraft I think
It's like flying a lounge Chair. The video in the air is amazing.
Superb effort! I reckon you could go with a single motor and large folding prop to make a great self-launch soarer. Not being weight-shift / billow-shift for control is the way to go. This is sooo close to my dream aircraft!
I iv been following the e help for some time and I think if u use the turnigy ultimate 7.6 amp-hr you will get the same voltage but with 60 ah and 90c discharge. this will boost your flight time with additional 10 min at least. and less weight. all respect to your project
Very very nice! Thanks for sharing all the info.
I've always loved the millennium. Why is nobody producing this or something similar?
It could be produced a lot cheaper than a swift and transportation is a dream compared to a swift.
I have one question: where do you put the batteries? All behind you?
That looks like a blast! That could charge off a 1KW solar installation great! How long is the endurance? How well does it soar? How much will it cost? When will be be ready? This is non weight shift right? How do you pitch it? Answer the questions than shut up and take my money!!
Hey man, beautyfull work! How do you mount the props? And do you think that one engine would bei enough for a para-glider solution? I only weigh 50 Kilos, which should make things easier.
Also, looks like you have some sort of rocket-propelled chute on the back, for emergency recovery? What's the min altitude for deployment of something like that? Forgive me, I'm a curious guy, what are you using for throttle control? I'm guessing you wired a potentiometer-based throttle lever up to a mcu or something to output the proper PWM signal to the ESCs? Are you using differential thrust at all? I see the motors are mounted pretty close to the centerline. Have you tried flying with only one motor, mid-air, to see how badly that affects the yaw? I'm curious if it would be possible to continue with only one motor in the event of a birdstrike or something.
I think I'd feel happier with a longer runway than that! ;-)
so cool! how many meters to take off??
Have you tried a single engine (engine out scenario) approach. How does it handle the yaw ?
Excelente! Cuántas rrebolusiones tiene el motor?
What size is your motor and prop ? I have 2 x 10kw motors and 27" props, max out at 140 amps, how would that go ? Warren hall vic.
so... been flying it still? any improvements?
What airport are you flying this from in Arizona?
Once you're in air, can you shut off the engine and glide? That battery doesn't look heavy.
Beautiful!! Where can I buy a millenium hg? I am in Mexico
Beautiful plane, cantilever wing, looks simple, way-to-go. Cantilever class without the price tag. All you need is a slick-o canopy to match. Better glide ratio too.
What is the flight time on that, and the average cruise speed and cruise power? Also how much does that weigh (empty) Thanks!
great landing
40kgf thrust is that per engine?
what was your motor spec and kv?
I really like the joystick and rudder pedal controls, which make the control inputs of this craft analogous to those of a regular aircraft. What I do find a bit unnerving, is the pilot's lower spine sitting so close to the tarmac in this craft. A rough landing could cause the pilot to impact the ground with his back. Perhaps larger wheels and a tricycle configuration, might raise the pilot's seating position a little higher, and reduce the chances of the pilot hitting the runway with his spine during hard landings.
This aircraft is usually flown as a hang glider that I launch and land using my feet. The "seat" is really a harness system designed for foot-launch and land. A dedicated ultralight version could have a more rugged fuselage. Here is the same aircraft flown as a hang glider.

Thans 4 the video. I know same and some how it will and can be done.
Nice ride.
It's like a powered swift. Great!
Is there one flying in California ?
Well that's freakin' cool as hell.
airports will need to start installing quickchargers soon
Cheers
Though for that a 110V outlet or 1kw solar installation will do just fine. It's only a 2KH battery.
@@skyearthocean5815 in fact, you could put the solar on top of the wing. It's 14 sq meters, averaging 150w/sqm you get 2.1kW. Half an hour in the air (as the op predicted), half an hour on the ground, recharging. Pretty good.
Hi Steve. Thanks for the info! At 3:18 you say you are charging at 1KW. If your voltage is 53V, that's ~3.79V/cell, or ~41% full according to a charge curve I have. That means you had used 59% of the pack, or ~40*3.7*14*0.59 = 1222 Whr. So, at a 1kW charge rate...I'm thinking the charge took ~1222/1000 = 1.222 hrs, or 1hr 13 min? I'm just double checking your numbers. :) It's all interesting to me.

You make the rest of us feel like cavemen
she may not look like much but she's got it where it counts kid
Was that from Real Steel?
@@garrykennedy5484 : you're kidding, right?
@@shinobi1kenobi75 LOL Yes. I saw Star Wars at the theater when it first came out in 1976.
But will it do the Kessell Run in less than 12 parsecs!
why not using three wheel for balancing, is any reason using only 2 wheel?
I was thinking the same 3 or 4
I laughed when I saw the GAS powered generator hooked up to charge the battery. Electric powered. LMAO!
Awesome! Can you post links to the motors & ESCs in the description?

smorrismlbco Great Vid, Mate! Could you tell me what props you are using here, and how you like the performance for your setup?
Hi smorrismlbco
If use battery 5 Cell 12V/10 Ah. It's can Flight, thanks you
Hi, have you got the plans of this wing? tks
No plans, this is a molded composite main spar that can't be home built. The glider was in production 1999-2001 but not anymore.
getting on your land locked land
that looks cool
Brilliant.
My dream is to own an electric aircraft.
is there any way that I can communicate with you.. please let me know..
Is it really a hang glider if you're controlling with elevons and rudder?
Yes, it's a clas-2 rigid wing hang glider. Check out my other videos to see me launch and land using only me legs as landing gear. I also "hang" by my armpits during launch and landing.
flight time?
Amazing!!!!!!
While cruising, what's your avg power draw and flight time? What's max power?
eRCaGuy The cruise power is 4KW. You can fly for 1/2 hour at this cruise power setting with the 30 lb battery pack. The peak power is 20KW (2 motor total) but we limit the throttle to 10KW (2 motor total) to avoid overheating the motors.
Also, I just realized a few minutes ago that I recognized your name. Turns out I know you. I'll be sending you an email shortly, so please look out for me. Thanks. ~Gabriel Staples.
How long can you fly on one charge of your Battery of 2kWh?
It is the most important issue of the desighn.
+jwserge I haven't done a performance flight test but the estimated duration is 30 minutes at a level flight cruise speed of 30 mph. It is also good for roughly 3,000 ft of altitude gain in 6 minutes. Usually I catch a thermal within the first 500' of climb and then I shut off the motors.
+smorrismlbco
So, just to fly w/out any thermals, this plane/glider needs power of (2 to) 4kW? Just to KEEP flight after the take off, on the constant altitude, i try to realize especially this issue.
Wow very nice
muito legal! adorei!
Dude you are smart 👌👍
Isn't it 14S batteries?
In the video you mentioned it was 58 Volts, but 7S 40AH will only give you 29volts and 1kWh.
It looks like such fun
roidroid Oops, You're right, I was typing to fast when I edited the video titles. There are 16 battery packs, each is 7S X 5AH. They are connected as 14S and 8P to make a 51.8V x 40 AH pack.
I am using the same engine and building an e-help system for a hang glider. Have you measured your thrust for 1 engine with the 30 x 12 prop?
Measured 30x12 Xoar prop at 12s and it shows more than 40 Kilograms on the scale.
hi there very cool! how did you set up the throttle control?
Trevor Kruger I used a simple servo driver for the throttle like this one:
www.ebay.com/itm/High-Precision-Servo-ESC-Tester-for-RC-Model-/361055615726?pt=LH_DefaultDomain_0&hash=item5410977aee
I also used a separate 5V battery pack to power it.
Genius !
That's fucking badass
Удобненько)))
what are the motors names?
Hobby King Rotomax 150cc motors (2)
Hobby King 250A controllers (2)
Xoar 30x12 wood props (2)
Batteries = Li-Po 7S 5.5 Ah
14S x 44Ah = total pack size (16 bricks) = 2270 W-Hr = 15.1 Kg
@@smorrismlbco Thanks!
Surely this cannot be classed as a hang glider, its microlight??
I fly it as a hang glider without the motor unit. It weighs 100lbs without motor. Look at my other videos to see it hang gliding.
i wantt one
I realize this is an old video but what hobby king motors and ECS did you use? can you draw a control circuit diagram?

did you wire them as in 2 sets of 14s8p one set for each motor? or 1 pack 14s16p ?
Looks so '70s but electric.
those motors are not designed for motorized hang gliding at all they are for model aircraft rc hobby king toy model aircraft. the way to go would be use a motor desinged for powered hang gliding
This would be the way to go when the gliding gets so popular that Chinese manufacturers start mass production of affordable BLDCs! Until then, the way to go is the RC world products and here's the real example of how it works.
Why were you taking your feet off the rudders FFS?! That is insane it's a sure fire mix to induced an asymmetric retraction...i.e SPLAT!... that low to the ground?. Jesus, are you even still alive?
Rudders can be mechanically coupled to the sidestick with a pull cord and you don't need to always use the pedals. This aircraft is usually flown as a hang glider where your feet are never on the pedals during launch and landing, that's why they can be coupled to the stick. This airplane has been flying since 2000 without any major issues.
