RC Airboat with a Water Cannon

In this video I'll show how i built an RC airboat for racing. The boat can travel on water, tile floor, and wet grass. It's powered by a 3S LiPo Battery (12V) turning a pair of counter-rotating brushlesss motors with 6" 3-bladed propellers. It's also equipped with a pump draw water from beneath the hull and shoot it out a nozzle at the front of the boat to knock over other racers.
I originally equipped the boat with an audio amplifier to play music as a gimmick, but i found that it added unneccesary weight and complexity, and couldn't be heard over the sound of the propellers, so I removed it.
The Hull is made from 3d printed sections that are glued together and smoothed out with body filler and epoxy resin. I hand-painted the parts instead of spray painting because I had a large supply of acrylic paints for arts and crafts.
Specifications (to the best of my knowledge):
Battery: 3S / 2200 mAh
Motors: 1400 kV
ESCs: 30A
Propeller: 6" / 3 blade / Pitch Unknown
Max. Current Draw: 22A
Water Cannon: 80 PSI / 4LPM / 4mm Nozzle

Your ability to edit and take us on a journey of your project is astonishing. Every voice over for all the clips are honest AND amazing. Love the attention to detail on your projects! Super informative, great job! Keep it up :)

The one thing that I can see that you might want to consider is some sort of mesh cap for your water canon intake, mainly to prevent potential damage to the pump if something gets pulled in and caught. During construction, it would have worked to just get a piece of plastic canvas to bond into it, perhaps a layer of aquarium sponge filter, but something intended to keep anything solid or to mucky from jamming up your water canon.

A speaker with danger zone playing ! That was a great idea 😂😂

Now it just needs a notched rear to the hull to help improve planing/stability a bit, and a steering gyro like RC drift cars have. Also a toggle for a differential thrust mode if you want really tight turns for whatever reason. Could have put some fiberglass strips or tape over the seams in the epoxy layer to really improve durability vs. CA glue, and some more sanding work in to improve the currently crude looking paint job. It's definitely neat, yet there's room for a few more revisions that could still make it even better.

Very interesting project! The boat seems a bit tail heavy - if better weight distribution is not possible, you could try to compensate by tilting slightly the angle of the propellers. This might also prevent that oscillatory jumping at high speed.

Nice project! Maybe you should try powering it with the water jet? If the first nozzle you came up with required half power to compensate....You could also try pushing the jet into the water rather than in air?

the 5v from the esc's are vbat (12V) pulsed. Putting both the esc 5v in parrallel blows one of the 5V BECs becuase unless the pulses are perectly synced, you'll get more than 5V until 1 of them blows.

Hey, I found your channel via the DIY CNC you made and must say, it's really impressive what you're doing. I have a quick question though, how do you reckon one is able to get into electronics, prototyping and so on. I've been really interested and I also found a makerspace near me [so I don't need to buy a bazillion expensive tools], but I genuinely do not know where to start. Do you have any ressources on where to start, or is it more of an "Find an idea, work out the rest along the way" kinda thing?

The back of your speaker needs to be enclosed to produce decent output. The hull would make a nice enclosure.

@whatelseison8970 Жыл бұрын

You should have just dispensed with the speaker and played the music through the motor windings, same as how the ESC's play their start-up ditty. You'd probably have to load MIDI files instead of WAV's but it could still be fun.

do you have the files for the fan blade? also some of the files are different than what shows in your video, like the mount for the fans. i noticed it has holes for the wiring and things like that. i have printed just about everything to complete this project but am a little worried i wont be able to finish it correctly. i was going to order the electronic parts you have on your video but was concerned that i might not be able to finish it since i cant find the fan blades.

Try making an H2O splitter through ionization around 3kHz, 10 kV, inserting atomized water between the coils and using a car spark plug system with PWM on the 12V side to generate the 3kHz. Measure consumption x H output.

🤔🙄. That's not at all how water splitting works. Even if that did split anything it would just immediately recombine.

Your center of gravity is to far back that’s why it starts skipping or bouncing as you hit full throttle so maybe turtle guy would actually optimize it

As a mechanical engineer, I really think he's an electrical engineer. I don't know many mechanical engineers with oscilloscopes. But do not worry about that. If you like what he's doing and want to do that, you need to invest more time learning on your own. Practice is better than uni.
