First test of my homebuilt ground effect craft UH-18SPW designed by universal hovercraft Check out my latest build • The Mud Skipper homebu... The MudSkipper
Bob Windt the designer is smiling down from up above! Great guy! Totally helped me build my hovercraft UH-12T2. Started building in 1980 and still have today, better than ever before. Thanks Bob!
That's the one... nice. Is a long while i'm building one much smaller and to make it portable by rolling it around. Around 4mt long and 4mt wingspan easily detachable. From my calculations it should lift in ground effect at around 45-50 km/h.... Rigid airfoil wings are ready, "fuselage" ready , engine ready. Need a propeller some framing and assembly and maybe if is not too cold, a foam helmet.
Brilliant, how's it going? I'm at the start of the journey now, mine will have to fit into a transit van in three or four parts. It'll be slightly bigger than a two person kayak and I'm contemplating foils on the wing tips to help with the water drag. Good luck!
Holy cow that is awesome! I wish I actually had the guts to do this rather than dream about it. You are going to get a lot of frankly shit comments from the usual suspects but tell them to think about Otto Lilenthal and Richard Pearce. The principles you are making use of are not new by any means but the fact you accomplished it yourself makes it no less impressive in my eyes. Strewth!
Amazing! Is that the black plastic they sell at home improvement stores to cover things? And insulation foam? At first I didn't realize UH 18 was a set of plans that other people built as well. Do they all use these materials or was the choice of materials your innovation?
Very cool. Concider changing videos title so poeple can find you better on hovercraft searches or such. Also if you lengthen the wings slightly you should be able to create more lift on lower speeds....
Amazing! Wow great footage! Is it possible for me to use and share this footage on my youtube page? I share footage from all kind of activities on our ocean. Cargo ships in the 1960s till now, oil rigs, fishing vessels, etc. Of course full credit will be given to the owner of the footage. Looking forward to your reply. Kind regards. Cheers.
You need to stretch the leading edge about a foot forward and increase the angle of attack but flare and taper the lift surface ( underside of wing ) so you dont have to use the elevator to push the tail down to create enough negative pressure above the wing, the added wing profile will reduce the amount of prop you need to get it in ground effect flight , and you shoukd have to back off the throttle a bit yet still keep it in the sweet spot, nice design though it looks a bit on the heavy side, but that might just be my perspective on a 2-!/2" screen
Sorry but all I could think of is the wings being to low to the water catching a wave or if a cross wind landing would be required. Big cartwheel splash.
Is it to us to get any instructions. Manual..book to sell?..or how we can get det alla about design, how to BUILD? Any WWW ? Or somebody CAN HELP US? NICE THIS CGI ..Thanks.
Can you tell me your specs - lift engine pusher engine etc - I have had the UH18 plans for the last 12 years but got distracted when I bought a conventional hover Paul Melbourne
@@Ground-Effect Had a subaru motor in my old hover - the separate lift engine simplifies all the belts the UH like to use with their V8's. You seemed to get the balance right with the later pass. Used to fly gliders where the ground effect would allow you to fly for miles without lift - its an amazing feeling. If I can find the plans i might build one to play with on Gippsland lakes.
@@Ground-Effect but you are the guy though?! This is your thing?! It's awesome dude I've checked your site out and everything with the kits and designs too. Great stuff
@@Ground-Effect love your response! "asdasadw0' priceless.....Now to the business at hand you did a fantastic job on on your Hoverwing. My question is with such small rudders and how far they sit back from the fan how is the turning authority?
@@chadharrison8653 Thankyou mate. Alot of work went into it! So with the rudders so far back you are increasing the moment (or leverage). This greatly increases the stability of the craft in yaw which is needed for flight. The downside is by increasing stability maneuverability is reduced. So as a hovercraft the control authority is poor and you loose the ability to spin. Also the hovercraft wants to always weathercock into wind. In ground effect flight the rudders are highly effective and only approx 10 percent movement is used in flight.
@@Ground-Effect That makes perfect sense, which leads me to a whole another set of questions.........Hope you do not mind I am just very interested and their is so little information on this subject here in the US. Yes we have HOVER-WING but they are very limited videos on them. Have you attempted an complete turn at 180 deg or even 360 deg?..... and if so how did i the altitude hold in that turn?....... Was it more like a rudder slip turn?....... or did the wing drop more like and aileron turn?.......How much up elevator was required through-out the turn to stay airborne?....Finally last question was there any fear of a stall especially during the turn or any other while airborne?.................................... Now let's re-address the"asdasadw0" in the room!!!! What I take away from what James said about the placement of his control surfaces are in the most optimum position for safety and no helmet required!!! I am certain that the intended use of his craft is to be a "W.I.G." (Wing In Ground Effect) Craft Primarily, and a Hovercraft second, hence having more control with less throw in the air is ideal. You see pilots are always thinking ahead "asdasadw0"that is just what they do! His design not only improves flight characteristics but also removes the ability/temptation for the craft to spin while running as a hovercraft which would be catastrophic if one of the wings were to accidentally "Dig-in" while attempting to perform the popular hovercraft spin. Therefore he has implemented a huge safety benefit and added it to this craft. Now my question to "asdasadw0" is.......The next time that you take a commercial flight which pilot would you rather come face to face with after they just flew you across the pond and as you DE-Plane, a crazy Aussie with a crash helmet and knee pads or a captain and first officer in fight their uniforms looking professional with reassuring faces that you are safe when you fly with them???
Looks like a 1960s popular mechanics article come to life
Howard Hughes is smiling in heaven.
Amazed it lifted in the air,,,, didn't think it could do it
Guy doesn't go in for the helmet...Love it ! The loyal dog adds to the whole spectacle ! Thumbs up all round!
He's not wearing a life jacket either.....
Should have took the dog, he was all in!
Bob Windt the designer is smiling down from up above! Great guy! Totally helped me build my hovercraft UH-12T2. Started building in 1980 and still have today, better than ever before. Thanks Bob!
Bro, that's madness! Love the idea of adding a hovercraft skirt to a WIG AND using the same material for the wing, seems like.
Doing first trial of a diy flying vehicle between moored yachts and a gas carrier is priceless...safety at first!
Ok Karen
Obviously the wind is blowing left to right. This dudes cool. Big kid. It worked! Haha
Obviously... always take off into the wind...

Cool, but why leave the dog behind?
Love the sound of the sea ! Can almost smell the salty air !
I just watched this, on the anniversary of the Wright brothers first flight... Beyond cool!
Great, just great!
Ad some winglets to get out of the induced drag trap! Have tons of fun! Love your aircraft 😍
he is tail heavy. I wish him luck.
He is stuck in the induced drag at high angle of attack. More wingspan or winglets could improve that wonderful craft.

Wait wait the dog wants to ride..
Off to the beautiful relaxing ocean.....to listen to a lawnmower run....
Nothing beats the smell of cut grass in a Sunday hahaha
Once it takes off in GE, can you turn off the lift engine?
We as humans can do just about anything we set our minds to do may not look super cool but we get the job done
Amazing! Is that the black plastic they sell at home improvement stores to cover things? And insulation foam? At first I didn't realize UH 18 was a set of plans that other people built as well. Do they all use these materials or was the choice of materials your innovation?
I don't want to be within a mile of that damn thing, but the FIRST thing that we need to do, is fire the camera "operator"
Strengthen the wings and spars, lighten the fuselage and then see what happens!
The dog...want a ride too....🥰🥰🥰🥰🥰
Interesting contraption.
Great comments. Lol.
Incredible !!! Real innovation is this a ground effect craft ? Good luck keep safe 👍
This is amazing!!!!
Tell us how you built this
Nice ride!. Got to pull someone on ski's with that thing.
First flight , farther than the Wright bros.
Very cool. Concider changing videos title so poeple can find you better on hovercraft searches or such.
Also if you lengthen the wings slightly you should be able to create more lift on lower speeds....
That was its first test flight. Check out my other videos
THAT’S AMAZING 🤩
Super awesome guy.
Thanks
Freaking Amazing!!! He's just amazing
that's incredible 👏
Love it!
It's just wrong on so many levels but I love it.
Good Dog!
Pretty dang cool!
If you paint it and add the registration stickers it won't fly due to weight . . . .
Brilliant
Amazing! Wow great footage! Is it possible for me to use and share this footage on my youtube page? I share footage from all kind of activities on our ocean. Cargo ships in the 1960s till now, oil rigs, fishing vessels, etc. Of course full credit will be given to the owner of the footage. Looking forward to your reply. Kind regards. Cheers.
Sure thing mate!
@@Ground-Effect many thanks!
Sweet stuff!!!
This is beyond awesome! So very cool to see it work. Congratulations!
(but next time turn your hat backwards) 😉
Super,il fallait oser décoller !!!!
A10 warthog from wish 🤣. Just kidding nice creation.
That's cool!
Ekrano...vercraft ??

Agree

I would look for a better airfoil. But very nice. Keep working this is good stuff. I like people spreading there wings "pun intended" lol.
Awesome!
The design is around a flat angle in the air but should have been designed for that angle.
Is it to us to get any instructions. Manual..book to sell?..or how we can get det alla about design, how to BUILD? Any WWW ? Or somebody CAN HELP US? NICE THIS CGI ..Thanks.
Black dog has no wings 💸
mate !! wheres your life Jacket ?????
Amazing
Can you tell me your specs - lift engine pusher engine etc - I have had the UH18 plans for the last 12 years but got distracted when I bought a conventional hover

Hey Paul. I've used a 20hp for the front and an ea81 for the rear

@@iCollabor8 Can you please explain how you stay in ground effect with a glider? What, like fly at 10 feet with no engine? What keeps you moving?
Next, a muffler.
Has one
From the side it looks like a big house shoe. LMAO. I think it needs more cowbell, I mean power. LOL
Probably didnt need to exit the vehicle after powering it on...I gotta say just don't do that
Righteo mate
@@Ground-Effect but you are the guy though?! This is your thing?! It's awesome dude I've checked your site out and everything with the kits and designs too. Great stuff
But why ?
Why not
That is some crazy shit!!! A plywood and plastic hover-boat-plane that really fuckin flies.
See my latest build here!!!!!
ruclips.net/video/vBSJQpCJsPg/видео.html
That's a nice CGI effect, it looks legit.
Hahaha. Its raw video dude
@@Ground-Effect Raw video, indeed. You need a better camera person. 😉
No helmet. No safety gear. Future nominee for the Darwin Awards?
There is always at least one 'asdwasdw0' to comment negatively hahaha
Well it is in Darwin

marine sh
Hey you did a nice job on that and you actually made it Fly kind of like to Spruce Goose it took you a minute but you got her going buddy
And now what we got a smaller spruce goose on our hands woohoo
Where is this at?!
Darwin Australia
Not enough power
It had more than enough power. Look at my other videos. That was test day one so I was cautious.
Bro, that's madness! Love the idea of adding a hovercraft skirt to a WIG AND using the same material for the wing, seems like.
