Underwater Thrusters with Brushless Motors for Drones!
Вставка
- Опубліковано 27 чер 2021
- Stingray FPV Drone Update: Now that all the underwater thrusters are hooked up to the electronic speed controllers, I’m programming my transmitter controls. The next step for me will be to build a test fixture with a tank of water to calculate the combined thrust output underwater as well as the current draw for battery life calculations.

Make the antenna look like a duck. Total stealth haha.
Seems great, good luck with the drone.
I love the idea of a little floating (but obviously waterproof) radio pod bobbing away on the surface.
Wow big stuff dude really big stuff I'm so curious... 👍
Not sure how i missed this video but ya the gasket is a great idea. I love when you are able to use highly optimized products from one industry for other more creative applications. Water seal tends to be the hardest thing with these ROVs. Also, water sealing for the cable is a bitch. Water likes to travel down inside the cable if you don't seal the ends well enough.
❤❤❤대단해요
This is something I wanted to test, ducted propellers. I expect performance gain.
Hi sir do you have a full video about your underwater thurster? I want a tutorial about that. I want to copy your project step by step. Coz it will help a lot tnx 🙂
I see the gaps between the blades of the props and the housing are very large, and on air drones they are very close. Has flow simulation been done to find the 'best' gap? That's interesting. I know that a closer gap on the air ones is better for overall use, but the much higher density/viscosity/reosity (I can never remember which one it is) would change it... Interesting. Oh, I suppose that in air you won't get a stick/seaweed in your prop either. Ahh, the gap might have more than one function!
I have the same motors was wondering which color is for which letter I have black red yellow and ECS is marked A B C not sure of the connection maybe red to A black to B and yellow to C?
Hi. If im only making 2 brusless truster for a kayak ( no remote needed manual driven) what parts i need to buy. Thanks.
Nice gasket. I am sure you going to seal that thing well. But have you thought of using a conformal coating on the electronics just in case? I have used MG Chemicals - 422C-55MLCA 422C Silicone on some ESC's because it has that flexibility when parts heat up. Just a random thought. Cant wait to see this one completed and running.
Yes! I planned on on using large clear heatshrink tubing I have for the escs and then sealing the ends with e6000 or rtv but I may take the camera apart and use a conformal coating on that board just in case.
I have used that conformal coating great stuff. Not fully water proof but great for swarf
Hello, I have a concern because I am Trying to build an automated underwater drone. So, naturally, the first part consists of making a drone. when using the left joystick, the vertical axis controls the speed of the motors? if so, how? and how does it steer? does the leftmost position of the joystick make only the right proproller work while the left stops, in order to turn right?
I apologize if my question was not as clear as it could have been and any clarification would go a long way thank you
How many ampere of ESC do you recommend for 16800 rpm 3-blade propeller with an operating voltage of 6-9 volts?
Ps. I'm just a student making a device in lined with underwater drone, limited knowledge when it comes to this. Thank you!
Hi. Nice work. Do you have any update on the build of the drone?
Thank you. I got a new job, moved my lab and I’ve been working a lot more lately. Hopefully I can get back to it but I’m not sure when I’ll be able to.
Very cool! Are you gona have extra batteries in the flotation device for the drone, or is it gona be just for communication.
Yes, there will be a battery there for the receiver and video transmitter.
@@ProtoG42 I know there has to be one for the transceiver. I was wondering about some extra power for the drone, transmitted through the tether. May at a later stage if needed.
I planning to buy 2 of this underwater motor and install it under ( fins) my inflatable kayak. Do you think its good enough to move the kayak with a weight of 150 lbs? Can i use a regular 12v car battery with on of switch? Thanks...
Curious did this work?
Hi. I want to mount 2 of this thruster on my kayak. Does this work with a 12V 100A/h lifepo4 battery?
yes.
Set it up for lateral movement!
No.
@@ProtoG42 fair enough.
@@wantafastz28 I may make a different version in the future with more motors, but this is a lower cost approach for now.
@@ProtoG42 look forward to your builds either way. Good content.
Why no motors for rolling the the drone?
Rolling isn’t necessary as the wings and buoyancy will stabilize the path underwater. There are a few other examples out there of underwater drones with only three motors like this. I would like to design a larger version with more motors one day.
Hope we get to see it in action soon then.
Check out the work of / do a collab with "Ascend RC"
They made a great submarine, and adding this thruster to it could be neat!

These thrusters claim full waterproof even in seawater but they are quite expensive, $146 cdn each, plus shipping. I know from experience that the average brushless motor will not hold up even in fresh water. The bearings get rusty and fail. In salt water forget it. Bilge pump motors seem a better budget choice. Take off pump and install props.
They not average brushless motors. They are sealed with a potting compound and do work in salt and freshwater. It cost me $50 USD and 1 day shipping. 🫡🇺🇸
