Is it just me or does their site look a bit scam:y? Not much information and what is there feels a bit generic and no spec to be found about the boards itself.
I live on the Isle of Wight where the only commercial hovercraft service in the world operates, I have been on it a few times and its always an amazing experience, the ground effect is definitely an area where more research should be done, keep up the great work.
5:54 that is the coolest camera angle i have ever seen! The water level in the foreground with the craft, and the street in the back with the scale of the hill
Now turn the surfboard into a hovercraft and you have made my dream come true. I have only imagined such a craft for nearly 20 years hoping to one day see it come to fruition.
Nice, the stability of the feedback loop on this one has indeed converged to something really satisfying. Another nice thing about the hovercraft motors is that you could program some differential-thrust-roll-control into those; seems roll stability is one of the limiting factors now and that might really help it shine in gustier conditions.
you don't need to get a degree to learn more, go get some foamboard and a cheap transmitter and start building! it will make your classes where you learn about aerdynamics wayyyyyy more fun
@@MrKyle700 exactly; if you are waiting for university to teach you something you will constantly be yearning for more. school is really great for teaching you the abstract math and physics behind concepts practiced but it’s up to the student to take this acquired knowledge and actually apply it. if i were you and passionate about flight, i would go to the 99 cents store, get some foam board and start filling up that resume!
I only recently made that exact arduino circuit, only to help me not smash into trees when hiking at night, very cool to see soneone else realise how cool ultrasonic sensors are!
A shot like the one at 5:54 is just so beautiful to me. Enough water around here, but nowhere close to me that actually has a hill like that in the (close) background. And I'm sure it's just some insignificant every-day-life shot for you :)
Excellent work, Sir! Perfect demonstration of Chord Dominated Ground Effect where Lift is affected, as opposed to Span Dominated Ground Effect where Induced Drag is affected. You go from strength to strength!
I love how good rctestflight has become at making ground effect vehicles that he can experiment with them in any way he likes and they still tend to work
If you watch that last demolition video from Testflight where Peter Stropol made the many, many winged plane that was insanely stable. I think if a person did something crazy like make a 2 or 3 part accordion super long plane that was optimized to be in ground effect, a prototype may be surprisingly effective,
in Formula 1 motor racing, the aero designers frequently will induce vortices at the front wing which serve to "seal off" the floor of the car from outside airflows, efectively making artificial invisible skirts. I'm not sure if this would work on the R.C. Scale, but it might be an interesting way to make a skirtless hovercraft. this MAY end up making negative lift however, which is obviously optimal in a race car, but not for a hovercraft of Ground Effect vehicle. Nice 124 Abarth Sebastian!
You might want to do an IR camera crack check on those panels now. They're able to flex but not intended to flex while in operation and the cells themselves will still get damaged. A lightweight yet rigid mounting substrate would be advised, or at minimum a support grid underneath.
Giving me some good ideas, in this video and the last one, for when I finally make my own boat. A solar powered boat, with sails and panels, sounds like a good and feasible idea.
We have water in every direction! Even all over inside the state! That board looks like a blast! I bet you can find a way to extend it's range, by A LOT. Nice work on the GEC!
Rule #1 is the 70% rule. All cruise speeds should be no greater than 75% max, to conserve parts and fuel. I admit, however, that's old screw powered naval ship lore. Newer designs might require different drive numbers.
Cruising at max, is really never a good idea, with all vehicles, for the two reasons you state. Extending range however, via more batteries wired in parallel @@up4open is definitely an option.
Man watching the plant come down and not even touch the water yet leaves this smoothed out wake was soo cool to see. Imagine if this thing was big enough to carry people. Kinda reminds me of the old Soviet Sea Dragon.
If you want to see a few takes on DIY water jet surf boards you can look at RCLifeOn and Hacksmith Industries. Both have videos on the construction and build of electric surfboards. RCLifeOn also tried making a Hydrofoil surfboard, but with very limited success. The RCLifeOn surfboard totalled about $3K in parts and seems to have reached about the same speed as surfboard in this video. I can't remember if he ever talked about the battery time though. But being DIY it's limited by budget and how much weight you can add. Don't remember much at all about the Hacksmith version. But their production is always polished so entertaining to watch. And they too have given the hydrofoil idea a spin. And they had a little better results.
low-alt option: light, thin rod with a hydrodynamic floater on the tip. attach it on a hinge to the nose so it trails under the fuselage. connect the midpoint of the rod via cable to a cable-potentiometer in the fuselage. use this, with some trig, to measure the altitude off the water in a more direct way. (similar to the mechanism used in a toilet tank) the experimentation would be to see how small and short you could make the dipstick. if it's really long, it could be measuring the altitude BEHIND the vessel, so a shorter, more vertical one would be better for measuring, but would also put more force on the stick, meaning it'd have to be larger to survive. 🤔
0:55 Instead of being circular, vortices in proximity to the ground become elliptical as the airflow is pushed outwards. This causes the effective aspect ratio of the wing to become greater than the geometric aspect ratio and reduces induced drag. Both lift (and airspeed for any given engine power setting) are increased. Consequently high cord wings are favoured in ground effect over high span wings for ground effect vehicles.
The water board was the best part of video Daniel. Sabation gets all the fun jobs. Did you just pitch 2 Sponcers in one video? I have so much envy and respect for you and your channel.. I have a flying field in florida. Welcome anytime.
Sorry, I broke etiquette by posting twice. Daniel, what is your _"LIM_ROLL_CD"_ or Maximum Bank Angle limit? ARSPD_FBW_MIN will prolly need to be tweaked too, as the FC is probably going into stall protection with such low speeds. Just wondering.
I'd be interested to see a similar vehicle using 4 drone motors controlled by a flight controller keeping it stable. Basically a drone but with wings so that the quad motors generate ground effect and stabilize rather than full flight. That or I'd love to see a "hover craft" that uses 4 quad motors and a flight controller to control its altitude based on sonar data. It'd would basically be a low flying quad at that point but the idea of it staying at a fixed low altitude above the surface automatically would be really cool. Not efficient at all but something about staying a foot or so above the surface like there's a force field feels so futuristic and cool to see. Especially if it can maintain that distance over uneven land.
the thing ive always wanted to see from you is an rc solar rover #4, basically one that would be a mars rover, give it a camera and gps and you could control it from home but have it drive extremely far away, itd have to be out of the city and in like the country or something but I think it'd be one of your best videos if not the best
@@up4openYeah, if they sell at all. An arbitrary paragraph with no spec information about the board(s) at 10-14 thousand dollars is not promising. An electric hydrofoil can be had for half that price (probably more efficient and fun too). The board also looks very nose-up and like it’s plowing through the water rather than riding on plane
@@ethanm3923 These guys are charging 10k, if you can do it for 9.999k, you'll probably sell more than them. And instead of doing it, you're negging them for the failures? YOU COULD BE RICH GUY. lol.
@rctestflight the flat/kf airfoil that you have is not great to get high pressure under the wing because it relies on the fact that the flow is constricted at the back with the elevons. You might be losing pressure that way. Try a more aggressive airfoil with some camber and a lot of thickness if possible!

I know this is a pretty old video, but the first thing I thought of when I saw this vid, was this plane, A-90 Orlyonok. I have always been interested in military aircraft both new and old, prototypes and working. This was a working prototype that never really saw the light of day but seems to be something similar to what you were looking to try to re-create. I am not sure how much scale comes into effect here, but thought I would point it out in case you were not familiar with this vehicle.
With the "hovercraft" motors you might get away without par thrust. You could switch the servo to turn the front motors, giving better yaw control without dipping the sides in the water. I wonder if small hydrofoils would help with the abrupt stopping, while also not dragging too much.
Funny, the Surfniko site claims 60kph and 120 minutes runtime, double and triple your results. 150lbs isn't large, so anyone bigger will see less. Love the board, wish they wouldn't BS
@@up4open I was gonna say if I were him I’d just scan the thing and build my own. He’s smart enough to build a better one probably would run on solar and he’d post the plans for free
Random idea on how to contain the air more under the wing. Add thin 3D printed struts going done forming a solid barrier and then attach a small hydrofoil to the end of it that will remain in the water. It would make a solid boundary that the air physically can not pass through and can help make it so the main wing is not doing all the lifting. Probably defeats your purpose as then it's more of a combination hydrofoil and ground effect craft, but it could be interesting to see. My guess is probably not worth it due to the drag caused from the hydrofoil and the strut, plus then they would act as rudder wanting to keep you straight.
I never tought i could complain about the lack of numbers and calculations in a video. Ok less, more, but how much? Maybe i'm the only one with this issue, good video, and good luck in your projects
This gave me an idea what if we add ground effect to maglevs to reduce the need for electricity and reduce resistance like once it’s going however fast the magnets would only need to be used for stabilizing and movement but not the lift at lest not entirely
The only thing faster than a foil is no foil. The final form of this thing is going to be a ground effect e-surfboard. This also would solve the single issue with foils (maybe retractable foils that turn into ground effect if you lift them back up once you get to speed - foils go down to get up to speed, then lift off like a self launching glider) here which is smashing into logs and rocks that are submerged (I'm in the Willamette Valley/West Cascades). Once we can do that, though, it occurs to me that once we're in ground effect mode we can traverse non-water sections of our path - now that seems like an ultimate amphibious vehicle lol
Add three sonar things for front at for the middle and both sides and use the average of all three to control it so water doesn’t mess with it and it will correct itself when it banks
I'm not sure when Logic decided rc and autonomy was his shit instead of rapping but I'm here for it 🤣. I love your channel man this is top tier tinkering and tech content!
18:23 Having spent years with high lift RC airfoils and gliders this is correct. Above one wingspan there's effectively no ground effect. If you're within 1/2 a wingspan the effects are substantial even on a basic high wing trainer. This teaches some bad habits to new pilots as they try and chop the throttle the same way to push through (down through) the ground effect in their next higher performance models/airfoils with occasional crash inducing results. Teaching students to come in fast on a proper glide slope "Navy style" with their high wing trainers to stick the landing vs floating it in on the edge of stalling fixes most of this bad behavior.
i'm still kind of new to OnShape, but I was pretty sure that if you added all your parts weights, location, materials, it would calculate the center of gravity.
Should try encorporating a hydrofoil in the design as well, i think the combination of ground effect and hydro foil should create a really stable platform 😊👌

Truly hope he upgrades the surfboard
Have you been thinking of making a new solar plane? Or is that long gone? Would be pretty cool to see a new version of it.
Indeed, and would be interesting to see if things has changed material/efficiency wise aswell since the last few years!
Yeah that would be good to revisit, solar panel efficiency has definitely increased since the last attempt.
I agree, this is a great idea
good idea
Yea I would love too see it too
That surfboard seemed neat until I saw the price. I was thinking 2-3k. Not 10,000 dollars....
10k 😳

@@johboh definitely not just you, I noticed that as well. All their marketing material seems straight from this video too.

This also would solve the single issue with foils (maybe retractable foils that turn into ground effect if you lift them back up once you get to speed - foils go down to get up to speed, then lift off like a self launching glider) here which is smashing into logs and rocks that are submerged (I'm in the Willamette Valley/West Cascades). Once we can do that, though, it occurs to me that once we're in ground effect mode we can traverse non-water sections of our path - now that seems like an ultimate amphibious vehicle lol

The Shots are Great in Slowmo.
The Ground Effect boat, i wish it would looks like the Blue Falcon from F-Zero
Hydroscopic ducks would be fun! "Like water on a duck's back" haha
Looking more and more like an Ekranoplan... which kinda makes sense...
Just a quick FYI. Sony Venice 2 didn't shoot Top Gun: Maverick. That was Venice 1 with the original Rialto. TG was shot in 2018.
Add three sonar things for front at for the middle and both sides and use the average of all three to control it so water doesn’t mess with it and it will correct itself when it banks
I'm not sure when Logic decided rc and autonomy was his shit instead of rapping but I'm here for it 🤣.
I love your channel man this is top tier tinkering and tech content!
18:23 Having spent years with high lift RC airfoils and gliders this is correct. Above one wingspan there's effectively no ground effect. If you're within 1/2 a wingspan the effects are substantial even on a basic high wing trainer. This teaches some bad habits to new pilots as they try and chop the throttle the same way to push through (down through) the ground effect in their next higher performance models/airfoils with occasional crash inducing results.
Teaching students to come in fast on a proper glide slope "Navy style" with their high wing trainers to stick the landing vs floating it in on the edge of stalling fixes most of this bad behavior.
Looking forward to the next iteration of this craft
Can the air escaping from the pistons be directed in a way to provide a little bit of additional thrust?
Daniel, I love watching your videos. Thank you.
i'm still kind of new to OnShape, but I was pretty sure that if you added all your parts weights, location, materials, it would calculate the center of gravity.
Should try encorporating a hydrofoil in the design as well, i think the combination of ground effect and hydro foil should create a really stable platform 😊👌
I think this would work really well with that dangling stick design.
