You are so underrated
Feel free to share my stuff 😉
I'm absolutely agreed
@@Project-Air Haha!
S.t.u.p.i.d
Yep
"Might get a wet foot here"
_puts entire shoe underwater_
Love the video man! Great project and can't wait to see more
😂😂
@@Project-Air maybe a pair of rubber boats and a small rubber dingy(boat) would be nice to invest in.
Silver soldering for brass-to-brass. Get a beefy servo for high resistance in water.
Gumboots.
Excellent Idea
Great work, need to improve on "winging it" and look at areas where you could efficiently make the structure stronger and more homogeneous for V2.
Ya what VolV8 said👍👍
James I appreciate your honesty and how genuine your videos are, I can see how nervous and excited you are each time you test something for the first time.
I know exactly how you feel, when you rushed the last part of something complicated and when it starts going a little wrong you just want to go ahead and keep trying anyway!
Crashed quite a few experimental RC planes that way.
Anyway, thank you for the beautiful filming, editing, and workmanship.
Love the use of the laser cutter. So much more professional-looking afterward than 3D printing although everything has limitations and uses.
Looking forward to part 2!
I always liked these kind of boats. Built a large one myself years ago with multiple coaxial motors (two sets). In my opinion, you should not mess with your original design in order to get it to skim on the water. When you increase your throttle further, you will have a tendency for the rear to want to lift out from the water due to your motor being mounted horizontally (parallel to your hull). The motor will induce a substantial torque on your frame, something you will experience once you open up the throttle.
Looking forward to see where this goes. ; )
Nose weight
I believe by installing two smaller pontoons on the rear of the boat will enhance the performance
That was great, good choice on colour, the bluebirds speed records motivated so many people into engineering. I think it's a fine tribute to Donald!
Wow! That's really impressive! Your projects are always so cool!
You can add 2 rudders instead of 1....it will make it more manoeuvrable........and yeah, making the tail skid larger is a good idea...but don't make it too large...instead make the entire thing a little( JUST A LITTLE) nose heavy..... And if you want to use servos to steer the rudder, get powerful ones....cause at high speeds in water, small servos may not work....
And one more thing...I love your videos😄😄😄😄😄
Cool project! My thoughts....
- place the motors side by side to avoid efficiency losses
- place motors as low as possible to have thrust line more in line with CoM (reduce pushing nose down)
- place motors as rearward as possible (same reason as above, plus counterweights the nose being pushed down)
- move sponsons forward so that less of the torque due to thrust goes into pushing them downward
- use aero rudder and maybe even elevator to trim for desired pitch, if you get anywhere near 100mph these will become quite effective (not sure if this is against the rules though...)
- maybe widen rear skid?
- maybe rotate sponsons (pitch) a bit so that the angle between their bottom surface and the water is as shallow as possible at the target speed
- the further rear-ward the in-water rudder can be placed, the more effective it will be for the same drag
You mentioned in a comment that you wanted a pair of CW/CCW props, but I doubt it will matter. It doesn't even matter much on a plane which has no (relatively) solid water surface to steady itself against. Just use two-bladed props of the highest pitch you have available.
Regarding weight distribution, I pondered this a bit and it seems to me that you probably want to have equal 'loading' (g/cm2) for each of the three support points. But I don't know for sure, and it would be near impossible to ensure you're getting this at the target speed anyway.
That concludes todays know-it-all lecture :)
Isn’t it more efficient to have a push and a pull prop? The Mars helicopter is using in-line props and the fastest propeller plane in WWII was a late German design that had a pull prop at the front and a push propeller at the rear.
@@steviebee1989 nope, at least not when they are close together. I think the props on the DO335 were far apart enough that being inline with each other would not be such an issue, plus they weren't particularly concerned with efficiency. Mars helicopter is probably subject to a whole bunch of constraints which steered them to that format, notably the extremely thin atmosphere which requires as much blade area as possible, with smaller blades (eg. a quadro-copter) being ineffective.
Oh shit you're here!
Lovely content you make as well, New zealander.
Some quick reads say that contra rotation provides between 6% and 16% more efficiency than normal propellers. You also can get more thrust by using them as a "staged accelerator" by using a high pitch second prop
You could drastically improve performance by shaping the main hull instead of leaving it as a semicircle. Love the videos. Can't wait to see the next update on it
Pretty fantastic work, James! 😃
Looking forward to the the improvements! 😃
Stay safe there! 🖖😊
Great work and a great video, love to watch a detailed build,
makes me want to get the tools out :-)
Awesome video, can't wait for the next one!
Keep up the good work. As usual a very interesting video and project :)
Crazy big. Looks awesome!!
Ooooooooo I have been waiting for this since I saw the first one. Legend!
Really great video and project. Yes very excited to see the changes and the next video!
Was thinking to convert a rc car to a rc boat and was wondering how to make it really fast and then saw this video and now I know exactly how to do it! Thanks :)
I really enjoyed your video and all the work you put into your boat. It takes lots of trials but you will get it. Hang in there.
love the pace of your Video. Really great to watch!
Great project and great video ! One little thing, your trailing edges are round on the side floats and the round belly of your main fuselage will not help break the water tension, it will keep being sucked by the water by negative pressure just like a venturi effect. Take a look at some real (vs RC) seaplane floats like the Piper J3 or else, side edges and trailing edge are straight and sharp. Just my 2cts as I struggled with the same matter designing my own RC seaplane floats a few years ago. Keep it up, always loved your channel :)
Great job! love the blue bird. You will need a quarter scale steering servo for a hydroplane that size and put it inside the hull where it stays dry. use a waterproof boot and run a 440 rod to the rudder. Don’t ever swim after a boat without a lifejacket. I use a small rc retrieval boat with a fishing line attached to retrieve most of my dead boats. hardly ever need to use a rowboat. Keep up the good work brother!
Wow this guy, he is amazing, for me it was a massive achievement that i got a drone to fly first time, and this guy is out here beating world records, recreateing dam busters, making cool stuff, awesome. 😀
looks like a great start! lovely colour.
Hey James, make sure your props are made for max thrust at cruise speed, not max static thrust. It looks like yours are a relatively low pitch; you might want to switch to higher pitch props.
You could even put a helicopter tail rotor mechanism on there for variable pitch! :D
Edit: Also do seriously consider differential thrust for "rudder". Not dragging a surface under the water should help tremendously at high speeds.
Im a 40 year old Father of 3 my eldest son is 10 and im showing him your video so he too can learn something and be inspired .
You have good manners and i respect the fact you show your failures as well as your success
Keep up the good work
You have a great future ... all of your projects and presentations are excellent..
I can’t wait to see the finished project keep on doing amazing zings like these 😉🇪🇸🇪🇸🔥🔥
Very very cool!!! Dan Jones built and amazing boat and I think you are well on your way to an equally amazing boat. I've sub'd to your channel because I anxious to see your progress and end results. Best of luck!!!
Really looking forward to seeing what you do next! I agree with some others here - you'll want a stronger servo and maybe dual rudders. (I'd love to know how much control you'd have with the one that scarpered. My intuition is it might have you wanting for rudder authority.) Simpler than dual rudders, an L shaped one extending father backward would provide more authority without going terribly deep to snag on things.
Great project James! Considering the speed record edf would be a better choise as you get far more airspeed with them. Also you will probably have some issues with water splashing into the props and slowing them down
Just subscribed. Can’t wait to see what’s next!
Awesome Bro love your projects
Project Air is the type of guy to always lose his rudder.
Looking forward to a working model. Truly incredible 👍🍻
Super nice video and pretty awesome build
Nice concept! Love the boat
Also Nice vid
Wow! I love ur technique. Simple sturdy
Very cool James 👍
I got the notification for this video on my phone assuming this was RClifeon, started it and heard Tom stanton talking, then realized i was wrong again 😂 you got a new sub man
excellent video, real and interesting, keep going
Great videos man! Props from the us!
I still dont understand how you only have 30K subs, you deserve so much more man
You deserve more subscribers. Your projects are awesome!
Thank you ☺️
Couldn't agree more.
your channel is so professional and you deserve way more subs! nice scenery too. keep up the good work
Thank you!
you are so good to make this video, i like it so much
I can't wait to see this fly!
Only those who have driven an air / fan boats know how it feels. Love the feeling they are so special to handle! I've built two, but not this big. I think you're right, this one has alot of potential!
Thanks!
Love a good challenge. Go break some records 👏
Great content!
Great video and we hope to see more of Blue Bird!
Looks good 👍
I think I would add a rear aerofoil. Variable incidence, and possibly gyro stabilised by the on-board RC system. (You can use a cheap one of these from a small quad 'copter). As the speed builds, and the trim changes, you could 'fine-tune' the trim from the transmitter. Well done, and keep up the good work. Britain needs young experimental engineers like you...
Now that a proper build :)
Underrated asf!
For the rear skid, you might be able to achieve the same effect as the thrust angle vectoring you mentioned you had hoped to do with the props earlier. If the skid had a pivot point on the rear of the hull, you could control the pitch angle of the craft with a servo control.
The mistakes always makes for fun viewing ! Keep going at it mate
Great job man🚤
Can’t wait to see more.
Excellent idea.
Well done😎
I always love rc type channels
Nice idea!
Good build mate looks fantastic. Me personally I would have large steering rudders on both pontoons.
Amazing project! Keep it up for sure! Just found your channel, new subscriber here. I can't wait to see where you take this project. I'm standing by brother.
I loveeee yourrr vidssss!😩💖
Great video
Great video ! You should put a cone at the rear to reduce drag
*Takes boat out of the water*
Ducks: "Yay finally!"
I love these types of builds. Wouldn't it be cool to have a real life version?
Really enjoyable.
I was thinking about a similar device to drop fishing lines away from the shore. More like a torpedo type so it would work better at the seaside cutting waves through. But you gave me interesting ideas, thank you!
Woow amazing

This...does put a smile on my face
Nice brother👍👍👍
Next level awesomeness
SOOOOOO SMOOOOTH
A heavy duty servo for the rudder is needed & move the rudder to the centre behind the skeg. The skeg should be shaped to a symmetrical aero foil. This should eliminate drag without compromising efficiency. Great project! 👍
Great video man. That back ride plate looks like it’s pretty steeply angled. May want to round it a little so the approach angle is better.
I've never seen ur vids but 1:00 minute in I already want more. Keep going strong
Thanks for the kind words!
Same here, just sub'ed
Wonderful story telling and a good and honest development tale for a record aiming build. That's how it's supposed to be :-) As a composite engineer with many boat builds on my record, I can't stop wondering why you don't use fiberglass as a sealant and reinforcement material. It's practically the standard of boats today. Off course when you are coming from aerospace, the perspective is a bit different. I have been building helicopter parts for Westland in kevlar-epoxy though in the past, and many passenger planes actually use a lot of composites today. It's a new world, I know, but the effort of learning may pay off easily. Speaking of... There's a company called Easy Composites in UK, who supply composites for hobbyists. They also have some DIY videos. I have experienced that PLA and glass-epoxy works fine together. So does plywood and fiberglass! You don't need more than a 50 g/sqm woven glass mat to seal and toughen the PLA a bit. 100 g/sqm and we are talking reinforcement... Good luck! Looking forward to see the next episode :-)
This reminds me of the PBRs we use to take up the Mekong. I sold the parts for scrap after the war and used it to start my very own tomato empire
Would you be able to go faster if you made most of the hull out of waterproof aircraft foamboard? Like the foamboard that Flite Test uses? It would make it much lighter, meaning more speed
Gosh, I remember back in 1968, building an Swamp/Air Boat powered by .049 gas engine. Dad was mad when I used it to flush Geese for the holiday table, because it worked so well, and he hadn't thought of it first. LOLS
Excellent content as always! Just get the rudder and leak issue solved and let's party! That hair though 🤩
I was waiting until I got a comment about the hair 😂 Thanks Tom!
Very cool. Loads of potential..
3:13 his other planes start to get excited about the new project.
this is awsome
love your vids
i dont care how old these videos are they are all so good
Well done! Love the setting of your machines! What kind of laser cutter do you use? Thanks!
Wow awesome
Maybe have ride plates on the back of the front skids, lots of race boats have plates that are manually adjusted to balance the craft at full cook. Also this looks really cool and stay safe
Man the things I make with access to laser cutter! Nice project :)
It's one of the great perks of my job!
Hi nice video , if you put one propeller on the left side and the other on the right side you can eliminate the boat rudder and seal the bottom .
PART 2 PLEASE!!!!!!
Also I subbed and turn on the bell
Nice video, well done! Maybe i wouldn't call it a 'super speed' boat yet :D
Don't stop developing it. Great potential.
As you suggested - subscribed and liked;) i had the same experience not waiting for the epoxy to cure completely and rushing my airboat to a lake... how do you manage impatience ( when glueing, painting and such) ?
chip up lad massive fun
