- In this EXPERIMENTAL PROJECT we use a 6 lbs motor DIRECT SHAFT that could delivery 25 kw at 100 VOLTS , but we use only 17 kw at 66 volt so the motor produce less heat . we also use 6 or 9 LITHIUM POLYMER BATTERY 16 AMP 22 VOLTS . 3 IN SERIES to got 66 VOLTS x 2 OR 3 in PARALLEL to obtain 32 AMP OR 48 AMP , autonomy is aproximatively 1 hrs 10 min .

Thank you for the help, and Congratulations on your great achievement. You've inspired me to re-engage my pursuit.
Hi, Louis, glad to see our motors works so powerful and stable. Hope you can help us make some recommendation, thanks!
Congratulations ! I am developing a similar project in a configuration where the propeller is mounted on the hand-glider. The trike is left on the ground at take-off.
THANK ' ,keep in touch with me , may be i can help you .
what is new with your ptoject ?
So what is the set up
Please provide details: motor name/brand and source. I began my own similar build, with 52" folding carbon prop (Aussie "Explorer" harness component), but died of frustration trying to order the motor from Hobby King😬. E-paraglider.com claims their motor is more powerful. Need more advice, please
THE MOTOR WE USE IS A 25 KW MOTOR , I THINK HOBBY KING MOTOR IS ONLY 15 KW . NEXT WEEK I WILL REVEAL WHERE I BUY MINE FROM CHINA FOR FAR LESS THAN RC SHOP.
Did you use the 50kv motor rather than the 80kv motor? this make sense because the would spin at 3300 RPM unloaded (66V * 50kv = 3300 RPM). They have a Hot Sale for the 25KW motor and ESC for $525.

we make the motors
Thanks for posting. I have a twin pusher harness ready to test running 2 30x10 props, 2 80kv alien out runners.. Im debating to try run launch or rig a cart like yours. My problem is how to keep the glider level on taxi if roll starting. studying your set up, Im guessing the angle of attack is held in place on taxi / ground by the center pole running from down tube to the rear of harness. ? Please advise. Thanks Jeff
Yes it'is !
Thanks friend, could you post some close up pics of the set up, (the additional center post at down tubes ) did you go with a rigid connection between glider and harness or does it allow some axial movement for pushing out / pulling in.
I am attempting to build an electric powered harness. The motor you use seems to be a big advance over the rewired Rotomax 150 used for the e-help developed by Reider Bernstein. No gear reduction! Saves weight, $ and time! Can I get info on the motor or how to build your setup
somehow?
I finally ordered and received my 25kw motor. Now I am trying
to determine what battery to order. I am now talking factory direct to a Chinese
factory that provides some kind of Samsung 18650 knock off. I have found on
some e-bike blogs that the Li-ion are the safest, longest lasting batteries
used throughout most major industries. The 18650’s have the most capacity for
duration, but limited to 4.7a peak current supply each. If I want to get
12,000w out of this motor that would be about 60v (a safe voltage that will not
penetrate the skin) at 200a. I think I was calculating about 16 series and 33 parallel
to achieve this, which I was also calculating to be about 60 pounds, oh-my. When
I look at the stated parameters here: it is 66v and 48a, that is only 3168w (4.2hp).
I do not understand how 17kw is being
achieved. Please help clear this up for me. Thanks Tom
P.S. I must have been looking at older specs. The specs I am
pulling up not show about 13A discharge. Less parallel, less weight. I will
have to further inquire about these specs with the Chinese company I am dealing
with. budgetlightforum.com/node/45325
Hi Louis, I was checking this post often for about a week and did not see a reply then stopped checking. Great to see your response. I have the 25k 50kv motor. frchobby.en.alibaba.com/product/60605705236-803101590/2017_Hot_Sale_MP120100_KV50_Outrunner_Brushless_Motor_With_22_S_380_A_ESC.html
I want to run at around 60v as well and also expect around 2500 rpm, 16hp (12kw) therefore I can go direct drive. However, I would like to go with Li-ion instead of Li-Po. It seems to me by your response and from what I have read on the subject that the Li-Po, event thought it is only 48ah, is capable of discharging much more current (which would quickly deplete capacity of course). I suppose you only need to draw more current to climb a few hundred feet then you can throttle back to around 3 or 4 hp to maintain altitude in between thermals. I am in Southern California so there are plenty of thermals. In fact, I can probably take advantage of thermal activity during my climb, which will add a dimension of energy management. Plus, I will be taking off half way up a canyon slope on my property. I will only have to climb another 400 feet to get to the mountain tops where I will be able to easily pick off thermals for hours and hours.
It seems that the Li-ion batteries that I am looking at, the 18650's, will not discharge as much current, however, the advantages are much more capacity, much more charge cycles, and much lower fire risk than the Li-Po batteries. So I am looking at having to add a lot more parrellel batteries (the up side, lots more capacity, the down side higher wieght) to get the current dischare of around 200a that I will need to achieve the12kw at 60v that I will need for a decent climb. From the rough guesstemations that I have done a Li-ion battery at 60v and 200a may end up wieghing about 40 to 60 pounds.
hi Tom
Frst i want to said you that you have the good motor for direct drive , it is the same we have !
For our battery that are 22.2 volt 16 ah 15c Li-Po where the 15 c signify that we can drive those battery 16ah x 15 C for a shorter period than 1 C , so for the take-of until 1000 feet we use the maximum energy from the battery , but we have a good climb rate to go to 1000-2000 feet . But after that those battery use far less energy to cruse to maintain our level .
so what you see in the video is what you can acheive with our setup .
i studied a bit to use Li-Ion battery , but you have to use a lot of those 18650 battery to obtain a nice take-of at around 16 Hp . Li-Ion battery can not deliver 15 C , may be 4 or 5 C . that signify that you have to use a lot of those battery to acheive a 160-200 amp that we use to take-of but after the take of you will run for hours with Li-Ion because the contain a lot of energy , but they can not deliver it more than 5 C when you need it the more at take-of .
That it said , if you can figure or find Li-Ion battery the can deliver more C than 4 or 5 please let me know , because we have other project in run and if you can find those ideal battery we will be very please to know it and use those un our future project . thank LOUIS
We have another project that will use may be only 4 battery . so 88,8 volt . but the new battery we found are 22,2 Volt 22 Ah 25 C so the final voltage and Amp will be 88.8 volt 22 Ah 25 C . this project is for a man that fly principally at Mont Yamaska Quebec (and i think is the best place to fly here in Quebec) so this guy need only those battery for take off to got the mountain . so he will not have to climb the hill with is jeep no more .so with those battery rated 25 C he will have enough energy to do is goal . after that he will soar on is own power for the rest of the day or even use exedent energy to help him cross-contry
those new Li-Po battery are more safe than earlier battery , they use more security to avoid short-circuit . but that said , you have to do extreme care of those battery . those are for serious person with good electrical knowledge .
but the advantage are numerous , more C available at take off . only 4 battery to connect to the controller instead of hundreds Li-Ion
if you want more info or photos of our project try to communicate with me at louis.therriaultalbatros. com
I forget to say that for 4 of those battery the weight is only 20 lbs total

@@louistherriault5737 Greetings! The battery that you mentioned above certainly looks promising! Are you currently (😁 pun intended) using that particular type? I'm seeing that Alibaba sells it in minimum quantity of 20 pieces, so that's a huge obstacle for me. How did you purchase ... maybe as a group of builders, splitting the quantity and expenses to make it do-able, or what?
I'm leaning toward getting the 25kw motor (for direct drive, 52" Bolly folding carbon prop) rather than the 15kw, since the ESC is rated at 450-500 amps, a margin of safety to insure that nothing will get burned up (I need to flat-land launch my Falcon 195 to 1000' + !?) Thanks for your advice.
Any other builders out there? Is there possibly a FORUM that I need to know about? Thanks to all who share good comments and informative input here.
