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! 🙂

@robertstark3326 Год назад

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.

@thisisyourcaptin Год назад

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.

@raymondblanchard2213 Год назад

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 😜

@0815mkl Год назад

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

@Nuclear_Rabbit Год назад

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!!!!

@stevemercer6743 Год назад

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)

@krazyeye5147 Год назад

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.

@raymondblanchard2213 Год назад

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 🤣🤣🤣

@darthhauler9947 10 месяцев назад

Two motors, mounted over the pontoon area with the pontoons bent slightly down for better stabilization, this would be OP AF. Can't wait.

@AmpAbuser Год назад

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. 😎😎

@teeztoyz Год назад

@Rob-kj3ho Год назад

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!!

@communitycollegegenius9684 Год назад

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.

@Rob-kj3ho Год назад

@@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).

@communitycollegegenius9684 Год назад

@@Rob-kj3ho And a rudder wouldn't hurt :o)

@michiganengineer8621 Год назад

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)

@DustyFixes Год назад

I love this! I was watching the sponsons at one point the front almost went under. Then you go from sponsons to dive planes.

@thomasohanlon1060 Год назад

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

@donmoore9166 Год назад

Needs a fog generator right in front of the intake. It won't change the performance but it would look pretty cool.

@ricknwater2759 Год назад

@waldogtv5486 Год назад

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.

@scottstewart5784 Год назад

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.

@alexanderfaucher1619 Год назад

Round two!

@bobjoatmon1993 Год назад

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

@dakotaknoble2556 Год назад

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

@rebelarcher5450 Год назад

You need a longer kayak with rudder controls , and make the sponsons a bit skinnier to reduce drag if they bite the water.

@TobiasKornmayer Год назад

With that Kayak you could also do Anakin's pod racer!

@eastoforion Год назад

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.

@wilfredo1734 Год назад

De locura total

@centauri9458 Год назад

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.

@jeffreyharville1918 Год назад

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.)

@MichaelMcFearin Год назад

@chrismillersrcfamily Год назад

@bjetpilot Год назад

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.
