I see this totally going wild with 2 motors behind him out sideways mounted on a back sidearm.
Also a front sidearm, both connected to long waterflow-streamy kajak stabilizers, fronts high enough to not break in the water!
Loving this project again, like all you guys do! 🙂
Please make this a reality, I want to see it happen!
@@MarvinWestmaas
Yes! Love to see this!
I’m amazed the phone survived 😂
The anxiety was real
Great video. An important technical note on boat hull design. If a boat doesn't hydroplane, and I doubt a kayak will, it will be limited to its maximum velocity as determined by the Froude number. To cut to the chase, there comes a point where no matter how much more power you put into the boat, it won't go any faster.
hydrofoils!!!
/me takes notes
Please make a Ep2 for this! this was such fun to watch!
They make rudder kits for Kayaks. Y’all need to get your hands on one. Will make round two MUCH easier. Maybe even a two person kayak where you can move the motor farther back.
Somewhere there’s a coyote watching this and thinking, “That’s crazy!”. I love this episode! Keep up the great work. I cannot wait to see all of you at FliteFest 2023!
Oh man, Lake mohawk. My family always use to have their family reunion there. Brings back memories. Grew up in Minerva
I cant give this more the one thumbs up and its not fair... please do 2 motors! part 2
also so glad to see stephan back in videos!!! the hype man if i ever saw him!!!!
As others have said, a kayak has a displacement hull and has a fixed top speed no matter the power. A planing hull will be much, much faster (e.g. try the same set up on a large-size sailboard or small planing yacht)
Yes you can really see the huge bow (displacement) wave created in the camera side shot. This will be virtually impossible to overcome and thus a speed limit is created from the hull design itself.
David is such a talented, mechanically minded artist. Now that you guys have proof of concept, a few tweaks to improve performance; sponsons need fiberglassed to lessen drag they're causing. And maybe visit the split intake idea. An actual rudder may be used by Wyle Coyote, Genius 😜
I love your channel. Josh reminds me of one of my good friends that is from New Orleans, but has been my neighbor in Florida for the past 20 years. Josh is a bit younger & has more hair than my friend Jeff, but you both make me laugh after a hard day. PJ
There is no limit to what you guys are capable of, and I am always here for it!
Let's GOOOO!
That design was hilarious lol
A split intake, looking like the front of an L-39 would give safety for pilot and unobstructed air movement. I was cringing at the thought of the foam giving way and the prop chopping up Josh's shoulders -big sigh of relief when it held together. Please keep safe! 8:35 David mentions a safety screen, Josh replies, "we'll do that very last" way last, after video 🤣🤣🤣
I love this! I was watching the sponsons at one point the front almost went under. Then you go from sponsons to dive planes.
Now you are ready to Make a proper manned foam Outrigger Hydro like the RC style designs made to haul arse - go faster with more power use a race water aluminum rudder shape to help track perfect and offset for thrust flow aka torque issue. Should be able to hit 24 mph ish. 😎😎
Now you have said it, you've got to do twin motors. Nice work guys. God bless
I would totally love a round 2, with 2 motors, differential power output and rudders under the motor pods.😂 As always, great video, keep it up. John S.
the motor mounts should have airfoil fairings, ideally counters-crew of the prop spin for a little bonus thrust ;)
If watching this doesn't put a smile from ear to ear on your face you should go see a doctor, or a shrink, probably both ! That was awesome !! Thank You Flite Test, you rock (da boat) !
I would attach two of the thrusters (maybe a bit smaller) to the side arms left and right. So the body of the "driver" is not blocking the airflow and you should be able to stear with differential control. Okay, should have watched the video to the end before commenting - lol
Been waiting for the video to drop this morning
Definitely need round 2 with 2 fans👍
Brilliant!! Your Motto "If you can stick an rc motor on it. Do it" then add more.. Love ya work.. from Aust 🦘🦘
where's peter when you need him ....lol😉
Awesome! Just needs holes on the sides ,top and bottom of the inlet for better air supply. Motor definitely needs to pivot too. Seems plenty powerful with one motor. 😉🤘
You need a much more stable kayak for this, like specifically a Hobie Kayak (Outback would be great). They are actually setup for "sponsons" or outriggers I believe as they call them. They have inflatable ones. They actually sail those kayaks, I have one with the sail and everything. The kayak would weigh a bit more, but it would be a lot more stable and maneuverable as they are even equipped with rudders.
Let’s go new Flite test vid!!!!!!!!🎉🎉🎉
Two motors, mounted over the pontoon area with the pontoons bent slightly down for better stabilization, this would be OP AF. Can't wait.
Hey Josh! How funny it would have been if you would have worn a Wile E. Coyote outfit?? 🤣😂🤣
Fantastic concept!!!
A displacement hull is going to keep sapping more and more energy, the faster you try to go. Ideally you want to look a planing hull - like a surf kayak (like Mega or Watertech).
Good luck!!
I looked for this comment because you are correct. The hull has an absolute speed limit beyond which more power will only make it sit deeper and NOT go faster. I have 2hp gas engine/fan on a pirogue and I get to max hull speed just past an idle. More power just makes a bigger wake.
@@communitycollegegenius9684 Exactly!! That's why you need the flat hull of a surf kayak, which will eventually lift out of the water and start planing. These kayaks also have fins which will improve stability without having to use the paddle (and thereby add unwanted resistance).
@@Rob-kj3ho And a rudder wouldn't hurt :o)
How can one not click on something so ridiculous and honestly awesome
The landspeeder is gonna rock with 3 motors.
That’s awesome and even better with 2 motors and a RUDDER
Love it! How about making a Pod Racer on water? balancing the forces to keep the leading pods from coming together would be an interesting challenge :D
pod racers just use power couplings......easy😆🙂😆
Needs a fog generator right in front of the intake. It won't change the performance but it would look pretty cool.
I think to counter the torque steering you could add a second motor and prop inside the exiting duct set to counter-rotate in a pull-push configuration. You might also consider streamlining the amas (sponsons)
With that Kayak you could also do Anakin's pod racer!
Set up a simple rudder, maybe like one of the old peddle boats, and add a throttle control on board...
You should have the outriggers amidship then maybe louvers on the back of the motor housing for steering and maybe the housing a little higher for better airflow. Just my opinion
ROUND 2 PLEASE, 2 MOTORS
Now that I saw the end of this video, yes, two motors, but don't be up a creek without a real rudder. Good Luck!
I need to bring my 18' sea kayak up. It has a rudder for better yaw control!
round 2 would be amazing
Ok idea for those motors. Could you mount them to a merry go round with a few chairs you can be strapped into and see who can walk straight after riding it
ahh Mohawk... childhood memories~
WE ALL WANT ROUND 2!!!
That echo when he sayed: „I‘m free“
It was just as funny driving to the lake with the 'jet engine' "mounted" to the back of the vehicle I'll bet you got a lot of double takes from other drivers.
I did think that the distance between the intake opening and the person's back was too narrow and was probably choking airflow a lot
you NEED a round 2, with twin kyakes catermaran style and twin acme rockets!!!
Another Amazing Project
Use a skinny but flat Jon boat, lose the outriggers, add a rudder. I'd go with a water rudder, so you can still steer when moving but not under thrust. Oh yeah - I almost forgot - move the intake around the driver's body - either above or split to the sides.
A twin engine with counter rotating props to cancel out torque roll.
okay this was what I like seeing when you make weird stuff you could use a steering wheel add some plywood to the pontoons to bolted onto the bar make the pontoons longer
I’m pretty sure my husband would fit right in with you guys!
I saw the thumb and read the title. I thought for sure this was Peter's channel.
After watching so many Coyote & Roadrunner cartoons, if it says Acme, send it back.
Can’t wait for round 2
You need a longer kayak with rudder controls , and make the sponsons a bit skinnier to reduce drag if they bite the water.
the half throttle to full throttle issue is the power you need to get over your own bow wake! once you break past that you will get a huge efficiency increase as the boat transitions from displacement to planing.
RC rudder and it’s good to go!
That was crazy good! I want one!
Absolutely fantastic!
Funny looking rocket, I wonder how well it would work in the vacuum of space
That was insane!
Props look amazing!
At 5 minutes into the video the thought of Tailspin comes to mind.
You guys never disappoint 😂😂😂😂😂😂😂😂😂
We are glad you enjoy what we do 😂😂 It Means A Lot
I'd love to see one with a contrarotating fan setup to clean the airflow a little bit and remove the torque
Now make two of these motor pods to create a twin EDF Meglacy!
You need a kayak that has a rudder and possibly a keel or skeg. Maybe two engines with differential thrust to steer.
You need to get a kayak with a rudder you can control with your feet!
You won’t have to worry about the paddle that way.
You might try adding a foot controlled rudder.
Put the motors on the sponsons. And put some water pressure on the sponsons so that they are actively holding you stable.
Can you do a second video that has 2 engines on it? It would be awesome!
Rocket:
a cylindrical projectile that can be propelled to a great height or distance by the combustion of its contents.
So this can't be a rocket unless you set it on fire!
Definitely 2 motors. Like A10 worth OG setup. And a rudder.
Have y’all ever tried the baking soda and superglue method on any builds?
And if so how did it hold up?
Need to make the a10 again with this setup 👌
Round 2 let's go 😮😂😂
Yeah, with two motors and no occupant, I'd lay odds you could get the kayak to "skim" on the surface and pick up a lot more speed. Like 3x or 4x.
Definitely. You could also add a wing at that point.
@@basikwashman Ha ha. I see what you did there.
@@basikwashman - very difficult to get ground effect stable at small scales
Wylie E Coyote would be proud!
I want one for my stand up paddle board.
Longer streamlined sponsions with fore and aft mount points, and thrust vectoring louvers on the motor!
I believe in the next build, try two units one on each outrigger. It would have more airflow, more power and you could use them to steer.
he's like a human choke on a carburetor lol Love the channel just an observation
Next build, 2 of these motors counter-rotating, mounted on a foam catamaran.
Round two please!!!
Need a longer kayak to track straighter and a skeg to steer with your feet
RC Kayak vote.
Oh man how I would like to see those power pods used for an LSA or Ultra Light.
Did someone say amphibious ultralight? Or kayak ekranoplan? Or Hulled paramotor with EDF.
You might want counter rotating props, one with higher pitch, or static blades. Carve a ring for the prop tips into the duct housing so they don't have end gaps bypassing air and making eddies. Do the new torroidal props help in a duct? Why not blades like the turbofan high bypass engines?
Can we see hydrofoils on the kayak for the next modification?? Thank you🤙🏼
Put the "Jets" on bearings so they can rotate left and right and a cam to direct thrust upward to counteract tipping on the turn. When turning, the inside diameter jet should turn fewer degrees than the outer diameter jet. Trial and error on upward thrust angle and rotation differences may be in order, but i am guessing there is math that can be done. Just not by me. Jets facing the same way and differential thrust will turn the boat, just not as quick or precise. You could add that in to counter the need for rotational differences I suppose, reducing RPM of the inner diameter jet.
Two motors either side, opposite rotation to counteract the torque and will free up the intakes please
How about this: THREE motors, one in the center for forward thrust, one on each side with differential thrust. That way you have more than enough thrust, and steerablity, And, Stability. (I would also suggest a longer kayak, there is not enough in front of the thrust in a short kayak.)
Yes please. Do two kyak hooked together with two motors. Then you can steer and have two people ride.
Rudders for the win.
Hey, try to make an ekranoplan, I think it will be fun
Can't wait to see the landspeeder on the water
