I think your best bet is to use a Radne Raket 120cc aero. It's tried and tested and I've been using my first one for about 5 years with no major problems. You'll need a 3:1 reduction to reduce the rpms to about 3000 so you don't spin the prop too fast. There are other rc plane motors that will work, but the Radne Raket is the most reliable and used. It also only weighs 15lbs.

No, I know that, but electric engine companies use the cc rating to let the consumer know that the motor is equivalent to a gas engine in terms of power.

there's a 1000ft cliff nearby where I live and it has lots of wind! So, just a wing would be fine. I don't think I'll be needing an motor and all.

For a 56 inch prop you'll need about 3000 rpms. My engine spins at 9800 rpms and I use a 3:1 reduction to get to 3000 rpms.

Weight is about 55-60 pounds depending on fuel. Handling is about the same, just make sure weight shift is parallel to the keel. Don't drop your hips and feet to one side like traditional weight shift. I'm planning on making a tandem version that has a support running to the keel and mounted just in front of the engine so I can make a prone take off.

I flew mine a couple of years back. I built the powered harness, but I flew it with a Wills Wing Falcon 2.

Great !

very nice mate ! great job!! regards from Poland

Those crazy cows always get in the way!

@McCrunluath The prop is bolted in at one end of the prop shaft and the cog wheel is bolted at the other. The bearings are sandwitched between the two. The prop and cog wheel keep the bearings from moving along the prop shaft.

How did you secure the bearings in the drive shaft cover? Did you use any inner sleeving to prevent the bearings from possibly moving? Did you end up just using two bearings, one at the drive end and the other at the prop end? Thanks for taking the time to put this out there for all of us out there!

@McCrunluath No, I didn't use any loctite. The prop and cog wheel hold the bearings in place. Can't wait to see your design!

You have hell to get 7075 in England, if you go to the glider makers they rip you off about £120 for an upright. But 6065 that is just as god and some times better can be got dead easy. I had two lengths for just under £40 enought for 6 uprights. Just as well, as with the site I aI flying and the winds i fly in, I broke two last year. Still dune gooning has it price. Cheers, Pete

hi bro,,nice i understand everything nice design bro,thanks for sharing ..great video.sensei!!

It turns back into a hang glider. I've ran out of fuel a couple of times, it's not a big deal as long as you have a place to land. I still have about a 10-1 glide ratio with my engine off.

Pete, I got mine from speedymetals an online metal business. They will cut and ship to the U.S. You can get 6065 and 7075 aluminum for cheap in the U.S. Wes

Anything less than 12 hp , you will have a very hard time to lift off, the first about 9 hp of that is just to bearly take u up the ground and any extra hp is what makes u go up... and if u use too powerful engine, that will not work either, since not only it will be heavy, also it will create much larger counter rotation force that will twist you to one side, Any engine between 12 and 18 hp will work, any other engine won't... The more aspect ratio wing u use to fly , it will have much better climb in higher altitudes ( not higher climb in the sea level ( the same ) but in higher altitude) The total take off weight/ aspect ratio = minimum thrust at sea level As you go higher , there is not enough air and density, so that number will drop so fast , so if you get higher aspect ratio wing , on the equation above you will have much smaller requirements for thrust and the engine will be able to create enough of that, 18 hp engine will be twice powerfull to minimum 9 hp requirements And 12 hp engine will be only 1.33 times more powerful Going from 12 hp to 18 hp is only extra 6 hp but the experience will be much different since 18 hp will be 2 times powerfull compare to 12 hp only 1.33 times ..

I was wondering, can you show us how to make the wing too? I really don't have the money to buy a wing, but I have some trash bags, scotch tape, bamboo, and my mother's sewing stuff.

@hangdog8055 I'm glad you liked it.

This is outstanding. Do you have a blog to follow or a webpage showing the history of the design/build?

Hi thanks for the reply. Did you use any loctite to hold the bearings in place, or are they just pressed into the housing? Thanks again. I'll be sure to put up a video of my own design once I get it going.

You can google Radne Raket 120 aero and retailers will pop up.

That should be fine. That's about the right weight.

That's how we make hamburger in Texas LOL. It was the cross fade on the video editor where I spliced the two clips together. I was limited to just 15 minute upload, but the complete flight is uploaded under my videos.

This is awesome. I just have 1 question, what if you ran out of fuel in the air?

Sure there is. Do some research and look up Turnigy Rotomax 150cc electric motor. You can find clips of it on HobbyKing Daily on youtube.

@J77RS Have fun on your T2. One of my friends has a T2 and he loves it!

Thanks for the quick response. I notice on recent videos you are flying a mosquito. Do you still fly your home built?

Hello, my name is Eugene and I live in Brazil glider pilot. I have long wanted to build a machine to fly this motor, but here in Brazil do not have. Would you help me by sending parts so I can build here.

thanks for the lesson!!!!! how much did you spend on all the material counting the motor??

chainsaw is your engine? , How many horsepower does it have?

Excellent vid, I'm now seriously looking into building one myself. What does the whole thing weigh, and how much does this affect handling when it's off? Also, did you consider any other mounting options, ie suspended from the keel?

i know :) cool stuff man, congrats on your home-made mosquito!

i dont have a lot of money wich motor can i use under 1000? i can get a 150 RC plane gas twin 2 stroke that gives 12hp thatone will work?

God, that seems dear for the tubeing, where do you buy yours? See where I get mine.. I have video of it on my chanel. An upright for my glider cost me just under £7 each.. Cheers Pete

200 for the aluminum, 200 for the reduction gears, 1000 for the engine, about 400 for the prop.

Cuánto es el precio que vale el motor?

Yep, probably too powerful and too heavy unless you're using or have a glider about the size of a tandem. For the 52 inch prop used on most powered hang gliders you want to get about 3000-3200 rpm at the prop depending on the type of prop. My harness weighs about 55-60 pounds depending on how much fuel. My max hook in weight for my Falcon 195 is 250 lbs. I weigh about 195 lbs so I'm right there at the limit. Some tandems can handle 400-500 lbs.

@wmadams1 weather is not so nice this year, i was waiting for my new machine-T2 , i have it from 2weeks ,so for me its beginning of season :) best regards

@ceugenio You can order all the metal you need from Speedymetal and you can order the engine by googling Radne Raket and purchasing the engine online.

GREAT SERIES OF VIDS!! DOING IT! How much was the Wills wing? Thanks for the inspiration!

hey wes how did you make the mouth throttle and where did you get the prop extender?

I have a friend Chainsaw 8.5hp engine 118cc and could work well thanks for the reply.

@wmadams1 thanks i will , yes its amazing wing!

do you think a scooter 125 cc motor will work? or a yamaha sr250 motor?

That should work. 12hp should be plenty of power.

👍

I bought a broke down Doodlebug and restored the engine. You can get a Radne Raket Aero 120 for about $1200 or look on hanggliding org and restore one.

@J77RS Thank you, How's the weather in Poland? Are you getting to fly?

👍 ✅

No, I flew it a couple of time and sold it to a friend.

Hey Adams where did you buy the kill switch?

The Wills Wing Falcon Used was about 1500.

by the way hows the glider comming i started making one yesterday i do have a 467cc rotax snowmobile engine for mine it weighs about 60 lbs im wondering if its too powerfull for a motorized hang glider with a trike under it?

good .....good ......good...........................................muito bom ....

thank you for your input 14 lbs sure is light ill check it out you have a suggested retailer or ebay does the trick?

How much it costs?

ok what engine whould you suggest i have a few like i said 467cc 2 cylinder rotax 2 stroke i have a 3.5 hp 4 stroke a 49cc 2 stroke engine ive also pondered making it a jet powered hang glider Or do i have to outright go and buy a dirtbike engine?im new to this so any ionput on engine is good just remember i will be having a trike not a harness

Hello, could I have an info? Where did you buy the gear?

Oh I see. Thanks :)

Get your H2 from a school. You can use their equipment and learn safely. It will be alot cheaper.

hi, from where do i get these thing for making my glider

Can you share hang gliding nano trike project if you have ...

I want Wings details and Measurement videos upload please

120cc, 12hp Radne Raket Engine.

the cart i made for it weighs about 35 pounds so far without engine

150cc electric motor

Hello, which engine is using, please? Where is this engine used?

14:22 cow disappearing..

About $1800 U.S. Dollars

you do know the cc measures the volume in the cylinder calculating amount of fuel/air mixture that can fit inside if its a 150cc electric motor its probably made in china by some dudes who dont have a clue.im sorry to dissapoint you.unless you ment electric start?

you forgot the y in copying

Nice job. Please contact me for some specs.

I did it with the Woodglut plans.

LOL!

LOL there is no cc in electric motors haha

I'm not very good at spelling! LOL.
