I took the old EDF Glider from last week and turned it into the EDF Seaplane! Check it out!

Project Air was created to combine sweet visuals with wild projects. One of my passions in life is making things and inspiring others to do the same.

Got a suggestion or idea? 💡 Comment down here and let me know! 👌
ProjectAir mate, great idea. Try waxing the bottom half, then use a wedge nose like a pby Catalina or the Lutz class gev
The dip in the wing is sinking it into the water,duct tape does not make it waterproof
The step should be slightly bigger , the wing is quite close to the water (bad for a seaplane)
do better waterproofing, ATB mate!!
It's digging in because of the angle of your step. Basically it's pointed down whenever it gets "on plane", so it can never rotate for take off.
Super fast plane, try to get 100mph or something and find the speed using a set distance and the camera...or a speed radar if u have one
The EDF is on top so the plane tends to dive into water. To help counter that you could try to adjust the position of batteries to have a center of gravity a bit more to the rear.
Also seaplanes don't have a flat bottom. There's a step. The problem is that without that the water tends to stick to the bottom of the plane and suck it down. Also the bottom should be more like a boat (V shaped vertically) for stability and also to prevent any ground effect (like under race cars to make them stick to the road)
Just look at picture of actual seaplanes...
England flying spots are epic!
Come over and visit! Always welcome! :)
Wow
The fan mounted above the CG will be creating a nose down pitch as you apply power, this won’t help the aircraft get up on the plane in the water so you’re battling with too much drag. Maybe try adjusting the angle of the fan or move its position to reduce the torque rotating around the CG. The hull is a flat bottom so lots of drag, a v-shape hull would reduce this. Keep up the great work.
Spot on! You stole my thunder. V shaped hull with step and up thrust on the motor. It pitched down on the hand launch until it got some speed. Best of luck.
That landing was beautiful!
After an close analysis this plane has a possibly th best design out of all the planes you have made there is only one thing that makes this one stand out
3:57 foreshadowing...
Your sub video is ironically what brought me here lol. Now I stay for the awesome rockets and planes.
the ground effect after it landed on the water in slow motion was absolutely epic!!
Sweet! Maybe the hull needs a bit of a redesign? It's almost as if the water is "sucking" the plane down and preventing it from taking off
I do so love your enthusiasm and the efforts you make, you try very hard and the most important thing is that you do try, and keep trying!
May be old stuff but if you want to make a plane being able to take off from water, you need to reduce skin friction with the water skis. Normally that is done by reducing the camber line on the bottom so the water doesn’t stick to the surface until the trailing edge. So look for that ‘stepped’ profile for the skis.
perfect landing
Brilliant build. Consider putting a thrust cone on the end of the EDF engine for some added thrust. Try about 85% of the frontal diameter of the inlet to get a sort of pinching-the-garden-hose effect.
Teggs Nose / Langley….. I believe that is actually a reservoir, there are underwater plughole that cause down pull there. Also provides drinking water to Macclesfield :)
Needs a v hull bottom with a step in it. The flat bottom sucks and sticks to the water. Shape the fuselage bottom like a float plane float and sponsons on the wing tips. 😎👍🏼
And I must add that I very appreciate your videos and work, it's very noticeable the amount of effort you put into these finominal video, everything from the plans, planes, and the amazing photography work!
Your videos are a lot of what inspired me to get in this hobby, and I guess it inspired many more alike!
So thank you for your great work and amazing contact!
Another good video showing 'no fear' as usual in pursuit of the hobby. If you revisit sea planes take a look at how the Polaris deals with wing floats.
The rudder on the Hyperboat is blocked by the step. There will be very little control once it planes off. Check out a 3 point hydro or surface drive deep v, then see where the rudder is. Its far back and in the water. You can just extend it down where it is but if you get any speed out of it it will be real twitchy in that far forward a position. Good luck with your builds!
Wonderful! Suggest you look at the bow and keel shapes if you haven't already. And with one engine maybe you need a low profile rudder
If you make the hull and floats like an inverted wing, it's going to make the plane want to suck itself into the water. That's what the step is for in the hull, to break the -ve lift and allow the aircraft to plane and then break away from the water.
Love the location again beautiful lake and sky
I like and enjoy your experimental approach,this is how we learn things,take any ordinary two float seaplane and fit an EDF pack either side of the fuselage,that should fly.
It's because of the position of the propeller, it needs lift from the beginning, for that it need speed(initially) or just keep the propeller on the nose.
Possibly, the thrust mounted so far forward creates down pitch, so the bow plows instead of getting it up onto the step, which brings me to my second point, being add a step so you can hydroplane with less hydrodynamic resistance in the take off run.
Great videos I enjoy the ups and the downs, you're a humble man.
Firstly, thumbs up for addressing the issue of potential water ingress (at least you tried where so many forget!).
Assuming that the aircraft´s C of G was set up perfectly for flight, if the aircraft taxiied nose-down, then surely the hull shape requires more buoyancy towards the nose.
I´ve seen "skimmer-type" floats working well on other RC aircraft, though I bet you´re right; you´d do better with true floats.
I hesitate to make my last little point, but then again you´re affiliated (if loosely) with Flite Test, who are affiliated to STEM. At the risk of being considered pedantic, then, I shall mention the fact that this is a flying-boat rather than a seaplane. If the aircraft´s fitted with floats which hold the fuselage clear of the water (think Schneider Trophy), it´s a seaplane.
I look forward to seeing this model (or a later iteration of it) rise off water; the landing we saw today was utterly beautiful and very gratifying to watch.
Nice job!!!
You should try connecting 3 planes together by the wing too and fly it
i think the problem is, you need to make the hull near the water step more straight (not very down angled as the wing will then have minus attack angle when trying to take off)
The duct fan does not contribute to lift at lower speeds. That is why most seaplanes will have props in front of the wing to generate lift by the air blown over/under the wings without the plane actually being at that (air)-speed.
Thanks for letting me know! :)
They have props not ducted fans because ducted fans have bugger all thrust as proved in this video.
yeah nice one, i spose you would gain some lift despite physical speed of the plane due to air blown over wings from props. Thats got my thinking about some of my own builds , ie pusher vs tracor engine mounting. Damn this hobby the learning curve never stops lol. But again, nicley thought out.
@@grim4this tractor is more efficient than pusher as the prop is in clean air/air that isn't disturbed by the fuselage.
Key is the hight of the step and its position, cause only that step decides about lift or swimming. And the real planes have a keel - for some reason like easier take off + straight flow and fly while getting airborne.
I would love to see an update of this plane and your improvements. Did you get it starting from water?
Pretty interesting and unique modell.
Hope it is still floating or flying and did not sink.
I'm afraid the plane no longer exists, but I'll definitely be developing the design and building a few more in the future!
Hey James, I really enjoy learning from your experiments! Keep it up man!
she flies quite well once she's in the air....landing even works well... the problem is getting there (I know...obvious...) Here's a few observations I spotted:
she's nose heavy.....floatplanes need to balance on their CG both in the air, AND on the water....
your fan needs some thrust angle to it...if it's forward of the CG, it needs to tilt up a few degrees....if it's aft of the CG, it needs to tilt down a few degrees.. (the specific amount you'd have to fiddle with) In both cases, you want it to lift the nose, not pitch it downward....
she's also sitting "too low" in the water....try adding a pair of small "rail floats" on each lower edge of the fuselage from foam; that should raise her up in the water...something like little torpedoes with like a quarter of them cut out down the length to fit the fuselage.
.your "step" needs to be at or slightly forward of your CG for it to be effective (again, to lift it out of the water and not pitch the nose down)
I wouldn't count on ductape for waterproofing. it's fine for shedding rain and splashes, but not for keeping water out if it's submerged; it's also "heavy" as tape goes Try clear packing tape...it's more waterproof (though no tape is long term), but should be good for short duration.....or you can try to seal with hot glue using Flitetest's method of "wiping" most of the bead off the joint with a scrap (the way they do for making control hinges)...that should seal nicely, but help minimize adding weight. another idea might be a couple coats of spray lacquer on the lower part of the fuselage, paying close attention to the seams. A third possible, use a good quality wood glue with an outdoor rating when you assemble, instead of hot glue.
I would also suggest you give your electrics Peter Sripol's waterproofing treatment...
hope some of those help!!
Interesante y bonito proyecto. Creo que el secreto está en confeccionar una canoa, el rozamiento del agua, es muy superior al de el aire. Intenta suplementar con algo bajo el fuselaje y así mantener el morro elevado, Pa razón el take-off! Muchas gracias y animo!
Stepped hull would be good too,keep up the good work
Thanks!
Hello Mike, I love to see your experimental craft ,what about an aircraft that can land on water and submerge to avoid detection !
Top quality!
All seaplanes from the past had a wedge-shaped hull. Might you try something similar so that the plane puts less hull in the water as it goes faster and lifts out?
You needed to make the bottom of the plane look more like the hull of a boat, the "V" shape would have reduced the drag on the aircraft.
Hi james i really like your videos and follow them
Tnx for your nice projects😍
Awesome video 👍
I'm inspired
Have you seen a PBY? The Catalina is one of the greatest seaplane. Copy that profile.
i really could have worked, if you look at the landing you can see that the step was working you just needed to get up on it. all you really need to do is redesign the floats so they are more hydrodynamic and adjust the thrust angle to help it climb out of the water and onto the step.
You should try to make a submarine though
well make a boat howl for the edf waterplane or put some FT seaduck designing into it! it will work
I love your channel, awesome videos! But my I make one suggestion that would makes your videos one step better? Get a hand held gimbal for your camera/phone that you film with. Makes your videos silky smooth. Banggood has some decent ones for cheap.
I think you should change the position of the step...
You should do a heavy lift drone or airplane.
The stepped hull is good, but you might want to consider creating more of an angled underside so that the center-line is a peak that slopes down to the sides, resulting in less contact with the water once you start increasing throttle, like so: avstop.com/ac/flighttrainghandbook/imagefdc.jpg
Have you not see what a sea plane looks like? It's a boat with wings. Your hull is flat and square, so it rides too low in the water. that's why the wing skids didn't work. Redo with a proper hull and you'll get it.
Pretty nice, dude. 😊
Take a look at the Sea Duck Flite Test made a few time ago. Maybe you can use those landing things?
put half a liter water bottle under the wings and let the plane float on it over water. we did something like that and able to take of from water. but it was 10 years ago and i dont have any footage of it
Thank you, perhaps you can make an episode, where can people get the electronics from, including the remote, and how to connect them together, or how to connect the servo easily, because connecting servos takes time and they are heavy
Noted ;)
Or angle of incidence
Erm, that took me 10 seconds of the scenery to know exactly where you filmed this.
That was a textbook landing for seaplanes
Your horizontal stabilizer is dragging in the water. For one it's slowing the plane as it's trying to get proper speed for takeoff, and secondly you aren't getting any air passing underneath the elevator to pitch the plane up. You would also need enough room between the tail and the water to get the necessary pitch angle to climb up off the water. Cheers.
fuck you
What about using a hyrdofoil to lift the plane up in the water? Might be able to get more speed and less drag.
If there is one thing I’ve learned from making boats with Duck tape it is that duck tape is not waterproof
I fly a lot of Seaplanes , You are experiencing the Plow Factor on the hull. Need a LOT of up elevator to get it onto the step , the ROW. rise off the Water. Fly a LAKE Amphibian LA-4-200 , 38' Wingspan FAA Aircraft, Need to have extreme up elevator and then onto the step.
Well otherwise great attempt. Hydro/Aero/Dynamics .
You should to more collabs
more like project water
Maybe try and make a video of a water plane made with non waterproof foam board (not using flite test foam..)
For the people who don't have access to these materials..
There is no engine on that plane. That is a motor. Engines use gases and motors use electricity.
Really ,you don't say. You are splitting hairs a bit .
Have you thought about building a rc waterplane more like the polaris from Steve Shumate?
You should use waterproof cases for your battery😅
I know this is a little picky, but it's not a jet powered seaplane. It's electric.
Your wingloading is too high for the available thrust. It also looks really draggy on the water. More power and/or less draggy tip floats, more wing area, flaps...lots of options. Also, EDFs are a pain in the neck. ;)
It's a cool project though and in terms of flying, I can't criticize it. You do cool stuff. :)
Thanks Joshua. Yep, I learned a lot on this project, and that's the main thing! Next time we'll have more success ;) Thanks a lot for your advice!
ProjectAir, don't thank me yet, you haven't tried it. ;) Either way I know you'll get it flying eventually!
BOAT PLANE BOAT PLANE
if you put lifter flapes are an hydrafoil wing if ront of the sea plane it will help it lift up and then the wings will grab air
I don’t know how you make your models work. Your sea plane had a flat bottom instead of a
hull shape. When you took off the pontoons the motor torque put the starboard wing tip in the water.
For a seaplane to take off it needs to get up to plane riding nose high. All your plane did was to plow
through the water,
Thanks for the insight
I like your videos and you come up with some strange designs. I would suggest trying the following on your sea plane: a) make the fuselage in the shale of a boat. b) put your pontoons back on and shape
them like the hull of a boat and balance
the plane so the pontoons barely touch the water. c) make sure the front of the plane comes out of the water on take off. Lastly I find that coating balsa wood
with a marine waterproof epoxy helps water proof the wood and seams. My suggestion would be to use West System 105 epoxy resin. Those are my thoughts I hope they are helpful. I would like to see your seaplane re-worked. Good luck and thanks for your videos.
try to make a submarine
enjoy your videos mate keep them coming :)
Where can I get plans to make that airframe?
Yes 300th like.
You could try make a plane made out of common materials around the house (except electronics) eg cardboard pencils lolly sticks
Keep up the great work👍🏻👍🏻
Hola, de cuánto amper es el speedcontrol?
Got a nice preview on ft fans and also where do u get their foam board from?
I get it posted from the Flite Test Store. :)
Don't u have to pay a bunch for shipping or do they discount u for being affiliated with them?
what foamboard do you use
Nice video!
What's this foam with paper layer called and where could I get it, please?
Thanks! It's called foam board and you can get it from here: store.flitetest.com/flite-test-waterresistant-foam-board-by-adams-25-pack-flt-2050/p674259
(shock)
The step should be in front of the CG
I just discovered your channel.👍🏼👍🏼
Where do you buy foam board in UK?
James Bond Submarine plane
I like that idea!
I wonder if you turned the motor around and made it a pusher instead of a puller?
try researching what you want to build. Design requires mathmatics. Trust me if you have thought it up I can garentee somebody else has already tried it. As for you flying boat try looking at the Lake Renagade aircraft. I am sure you can find it on line , everything else is! As for your hyper boat they race hyper RC boats here in the states try looking that up as well
The thrustline of the engine is above the water. So there exists a momentum around the. which pulls the nose in the water when power is increased. This increases drag, keeping the speed down and counters rotating for take off. 2 bad things. A simple solution will be to increase the angle of the thrustline of the engine so that it pulls a bit upwards (5 - 10 degrees). Make this angle adjustible to experiment. Increasing the Angle of Attack of the wing will also help. If the model flies ok as it did. , I would not experiment with the c.g. too much. 2 foam skids at the wing tips will be sufficient to stop the wingtips from touching the water. Apparantly the torque of the engine pushes 1 tip down..Check out the angle of thrust of this full size Grumann Goos when it is in the water. abc.action.news/watch?v=bwNI4hWAYoE
Electric jet engine model?
first
Plans/links?
Hi....would it be possible to send me that building plane of the aircraft?
I thoroughly enjoy your videos,
However I'm not sure you have a proper understanding of the word "JET".
Particularly ironic since the acronym EDF uses the same number of letters.
Yeah, I suppose we could call it artistic license ;) I was thinking it's sort of correct as a "jet" is something that produces motion by throwing a fluid (air) out of the back. :) A "jet engine" on the other hand, as a reaction engine, is indeed something different.
@@Project-Air
thanks for replying.
Seems to be a rare feat amongst UA-camrs these days.
I try my best!
it is amasinge
Lot of talking, short flight, more talking
Duc
Ductt tape is rubbish for waterproofing, use electrical tape next time :)
que des conneries !!!
