I think adding a 'V' bottom hull shape to your floats/sponsons should stop the hopping tendencies. Maybe 30º-45º angles on each side of the 'V' shape. Increasing the length of the rear's flat portion of the floats may also reduce bouncing.

[@rpurdey]

RoboTekno Having the bottom of the "V" (the keel as it were) on the inboard edge of the sponsons (like a bent "L") would help turning as well but a skeg of sheet brass or aluminum could be added to the inbd edge if needed. The centerline float could be extended considerable for flotation and "V" bottomed for ride and the motor placed on the front of the fin.

When I finally make one of these I will make sure to follow the rudder dimensions exactly because I know that was the secret to the success of his project.

Great job! I like your minimalistic approach. To all the people that are saying what needs to be done for improvement I say: Build one yourself and show us! If you think you can do better please do so because I enjoy watching new and innovative ideas. With that being said I have to go to my shop, I have a couple of outrunner motors in my parts bin and I think there is some foam under the bench....

[@AussieRCPlayground]

That was great! The finished product looked a little crude and messy, but very cool nonetheless. I think adding a rudder extension that would stretched into the water would help with turning and cutting the floats into a "V" shape (like boats) might help with stability. Would love to see a follow up video if you've experimented with this platform any further. Great video. 👍🏼

[@briansmobile1]

HYDROFOIL THAT!

[@recommit]

Get rid of the huge rudder & put a small rudder on the tail in the water. Some drag from a water rudder will also assist in anchoring the tail from flipping forward.

[@beyondfossil]

***** I agree. After watching this video, it seems rear pusher prop would be better. Because a rear propeller would push the hull of the craft down into the water for more stability without requiring the high angle of the front propeller design. Also, if accidentally hitting a duck in the water at high speed, a rear propeller won't cause the feathers to fly like it would with a front propeller! ;-)

[@nickvledder]

True. Add a turn-fin on the inside of one of the front-floats and it corners like on rails!

[@ThomasGreenhill]

Daniel, you should put hydroplanes underwater, below the existing floats; the way the America's cup boats have it. You will be able to go much faster and it will look a lot cooler without any of the bounciness you see here.

[@frost273]

That duck certainly got used to the craft after many days testing it on the lake :)

[@thejoshmoss]

These are my favorite videos from you, just playing around with a concept until it works. Feels like we are there with you learning stuff. Also, the way you cut your footage is always making me laugh. Thanks for your work and Please, never stop experimenting.

[@Subwaterfilm]

Well done... a really nice idea!! Well done,.. and thanks for showing us.... best wishes and good flight; Holger from Subwaterfilm

[@miguelsalami]

The front & rear sponsons are several inches too short they should have been continued towards rear and shaped flat for the last few inches. This would be the boats hydroplaning surface & it would then run smoothly without any of the hop you were experiencing.Turning radius is always wide on air boats. Very entertaining vid Thanks for sharing👍👍💛

[@vintagehobbies1]

Looks fun! +1 on the skeg for the front sponson and that should allow for better turning with less rudder area.

[@vintagehobbies1]

A skeg with the square area of maybe a dime would be a good starting point

[@pafff_3d]

It's really cool! Thank you for the video and for sharing your trials!

[@birdseyeview1543]

Cool Skitter Bug, awesome rudder measurements.

[@kwokwing]

Nice pond to test with. Good boat.

[@ein99999]

My reccomendadtion is to put two small little fins in the two front skids like glue two pens together right at the very end lip to keep it from bouncing and skidding and then you can make it track a little better. SO instead of a skid it a v shape but only at the very end where the two front skids make contact.

[@air-headedaviator1805]

Its neat seeing this quick spouts of building amidst the crazy equip you work with on the daily. I bet that turning radius of the foil would of been helped by a dedicated keel/rudder for the water

[@slysparkane808]

Great vid.. I do not know if you went on to more of this, but if you put a simple vertical fin on each of the front skids (above water not below) similar to a rudder but static (no control) your craft will turn much better.

[@grantsimon5778]

This is an awesome invention you should make the rudder long enough to go all the way down to the water and use that as your rear skid.

[@kallealatupa2690]

If you are still into this project, i suggest that you try putting a hydrophobic coating on the floaters

[@ladraode9dedos409]

Having fun with your best buddy is always great!

[@AndreasPelonis]

Did you try making the rudder go under water?

[@beyondfossil]

Cool RC project. Thanks for documenting it. I like hydroplaning effect at 5:28.

[@Designandrew]

It almost seems like it would have been better to make the rudder sit slightly in the water for turning. It might ad a tiny bit of drag but you wouldn't need much below the water to make a huge impact on the turning capability of the rudder.

[@2prophets541]

Try adding a Skeg board just a little aft of the traiKing edge of the motor. That should vastly improve the turning ability without compromising the Speed. It should work the same as a sailboat's Skeg. I hope this helps. Great Idea, and looks like a lot of fun. 😉

[@TheJohanJonker]

Once again, an awesome video, looks like a lot of fun...

[@scottwatson5767]

Look at a sailboat, add small keels to the front skis and a small one to the rudder sticking down into the water just a little bit. Tail does not need to be all that big. I bet this thing will turn on a dime with these mods. cool little build

[@GraemeRobinson]

Nice. If you put part of the rudder under water surely it would turn better. If you also included a submerged transverse foil (like an airfoil but underwater) that would lock the tail down for sharper turns. Fun project, thanks for sharing.

[@thedocdodge]

You could try attaching a water rudder to the main rudder, that'll help your water turns... My foamie water plane uses a small piece of plastic card attached to the bottom of the rudder that goes into the water to help with turning in the water

[@COREYEIB1969]

Fun post, perhaps controllable rudders in the water at the front pontoons, static rear end? Keep innovating

[@ty8626]

U have successfully created a boat!

[@crezzlin]

Cool, try cutting a V shape in them from legs, maybe stop it from skipping :)

[@shanks_1908]

Nice design! I think setting the front floats forward a little, or setting the prop back will give it greater stability with the water. The bouncing is happening as the weight is taken off the back due to the rolling moment caused by the propeller thrust. I believe this is why it was flipping over for your initial trials as well. Given that that the device rises up on the foil as it increases speed means that the point in contact with the water (and therefore creating a drag force at velocity) moves further and further back. As this drag point is almost in line with where the prop is mounted the only thing stopping it from flipping over in the water is the weight of he tail, hence the skipping as some of the weight is lifted. You could also try a dragging rudder that operates under the waters surface if you wanted :) This might give it a more locked in feeling on the turns.

[@bob2161]

I'll bet if you add some small 'skegs' to the inboard edges of the front sponsons it would turn a bunch better. I've used the clear plastic from blister pacs and cut them into shark fin shape with scissors. I cut a slit in the foam and stick the fin in the slot with a little bit of hot glue. Just don't 'go overboard' on the size of the fins. it doesn't take much. Good Luck. I always enjoy your videos. Keep up the good work.

[@hankrawlings6505]

Holly Shit i recognize that voice it’s the OUTSIDER 🤘🏻🇺🇸🇺🇸

[@michaelmarne]

If you would add a vertical piece of foam on each skid, extending into the water you might get a better turn radius :)

[@burkey156]

To improve the turning try adding two small keels to the forward hydroplanes and a small submerged rudder

[@javiermorton7170]

A general comment to this video and all your others. Heaps good. Thank you.

[@lucywucyyy]

i think it might be smoother if it had more contact with the water, maybe two long pieces of foam instead of the 3 small pieces

[@emi9294]

For your next project, make a skycrane with pontoons to retrieve your 'lost' watercraft! Mi-10 + Floats? :3

[@EnglishTurbines]

When Lawson gets older....hes going to remember the fun times he had with you Daniel....Great chop it and try clip though...:)

[@akujiwar]

Maybe adding small fins to the front floats would help with the steering. Reducing sideslip so the rudder got something to push against. Thinking credit card or similar matherial

[@defakosgr]

Very nice project. It might lose the bounce if you try to make the floaters a little bit pointy at the back and front. Like a canoe... Or (if you wish) like hydroplane's wing floaters. They are very stiff angled as they are now... Still, it's gr8!!! Good job! For better turning, try double rudder. You have a huge amount of air pushed back from the motor and the single rudder is not enough. (like swamp boat)

[@hasidavid2]

It looks like while turning the front floats keep sliding sideways. Try to something like a fin to the front floats. Like from a piece of plastic cards or so.

[@crgintx]

Your rudder should be in the water not in the air.

[@TrashPanda2801]

crgintx he's an airplane guy, what can you expect :p

[@alphaxard1]

it would be amazing if you two geniuses showed us your mad skills.i wonder what we'd expect

[@TrashPanda2801]

alphaxard1 I'm not trying to bash him dude chill out, it's still more than I could do to make something like that, I don't have patience to do stuff like this, and what I said was purely a friendly dig, nothing to be taken seriously at all.

[@Raycefan]

I’m no engineer, but it seems like you need more friction, i.e. more contact with the water, more drag, to turn sharper. It has very little contact with the water, which is good for speed, but to turn, it needs at least some drag to low one side of it down.

[@16BitTerror]

You should try making some hydrofoils so it glides through the water rather than on top of it. It does look really cool skipping across the water at full speed though.

[@charleslambert3368]

Maybe little ailerons of some kind would help one front float to 'dig in' and make it turn faster.

[@Bravo-5-K9]

If you add a single fin to one of the sponsors then you would get a better turning radius and less slide out

[@billhill897]

For better turning lengthen the body a little and add a rudder up behind the motor that angles opposite to the rear rudder or put a short running board under the front floats.

[@nathanshao6161]

that deja vu though

[@kflo1111]

I think if the front pontoons gradually tapered down to a point below the water line that would help with the bouncing problem and dampen the craft at higher speeds. More speed=less surface area required to lift out it of water?

[@jjrotogeek]

Dude. That’s awesome. Great thinking 🤘🤘

[@hotliner]

... nice vehicle :-)... not a boot and not a plane but it swims and fly over the water ;-)

[@upcycle]

it wud be interesting to build a suspension system for the front pontoons to dampen the bounce. Perhaps that might even allow for more speed??

[@upcycle]

wondering if you put a slight ridge on the front pontoon to give it something to bite down on the water when making turns?

[@rscarawa]

I was thinking the same thing. Either that or have the bottom of the pontoon cut at an angle so the center side of the float is not as deep to allow the outside to bite in. This will require lowering the cg too as you will get more flips. I think having the bottom angled might yield a smoother ride as less foam will be in the water too.

[@bdcoller]

Brilliant, as usual. Fun video.

[@arrowstheorem1881]

Very Interesting video!

[@sofamannj3434]

I would add a rudder under the rear float.....this would be in the water. Does not have to be large.....but I believe that it would help your turning problems.

[@Erik740t]

Very nice. Subbed

[@zoomie9134]

Why is the engine mount not centered over the main wooden dowel? Is this to overcome torque?

[@RavenRaven-se6lr]

Home made contraptions love it. At least your game to post👍

[@ShaneHerald]

what would happen if you also turned your motor and propeller with the prop?

[@Ultrarc]

Cool! Love the ending

[@Raptorofwarbbc]

its not turning because you have the foam blocking the airflow to the rudder

[@francoisBonin-phils]

nice, i think you have to put a pusher motor on the back instead of the front...

[@milesabove5259]

the first version seemed to run on the water a lot smoother, if you were able to control the angle of the front skids i think it might have worked and ran really smooth across the water.

[@Vape_Master69]

It would be so cool if you made a TV hydrofoil

[@UnfinishedProduction]

You should add hydro foils to the bottom, so it gets up on the foils, much like the sailing boat called a "moth"

[@UnfinishedProduction]

awesome video btw

[@johnnyllooddte3415]

you need a little keel in the water for turning even an inch wide would do

[@brianrydzeski6108]

Love the tail diagram.

[@reversemotozuki]

[@Cilvaa]

[@nikolai502]

i want to know why you have the propeller that high up, it gives more momentum to flip over

[@raymondo162]

+nikolai502 .........or that far forward....??

[@boomfiziks]

Nice work. I’m wondering, instead of an air-rudder, what about a water-rudder (under water) for steering? Keep up the great work!

[@MrSilverback62]

Cool as usual. Any thoughts about extending the rudder into the water to help your turns? BTW, I still use the tips that you shared when you were in high school, i.e. your two stage method of applying heat shrink to battery leads and using nail clippers to avoid snags on zipties. Thanks.

[@louiealdred2386]

+rctestflight Have you thought of connecting he motor to a servo in order to give it a smaller turning radius?

[@ardmovies]

aripa aripa andre andre yeeehaaaa

[@bungo7211]

The first design seemed to be very efficient when leaning forwards, maybe revisit that but try to devise a way to balance or control the lean like a gyro or balancer, idk.

[@SimplyDudeFace]

Has it occurred to you to try a version with an under water wing? A large number of hydro foils are actually flying under the water.

[@lllllsp1d3rlllll]

if u put a small piece of metal from the tail fin going down into the water then water and air would turn it .then it would turn on a dime maybe to much

[@matthewkomitsky6419]

[@monoculosofficial9934]
