I am 100% committing to make this. I'm too fluffy to sit in the back of my scanoe and run the motor without sinking the boat. this is the most elegant solution possible. Thank you. the internet is truly an amazing place.
That's great! Let me know if you need a hand. I've had to tweak the design a bit but the stuff on thingiverse should still work pretty well, especially with a lower powered motor like the watersnake 24.
Thanks man! I considered that ages ago, but this opens up a lot more possibilities - stay tuned! ;) Ahh my feathers, artifacts from a bygone era of breakable glass-nylon props :)
Haha you should have seen me once I got back, having dialled up the motor a touch. Very pleased how this has turned out so far! Bring on the biiiiig motor
East Texas Here; I'm a RC person also and this idea is very cool. Makes me think about doing the same thing. For the steering and tracking, put a rudder board on the shaft to the motor like I did. So, if the motor quits you still have the tracking when you have to paddle. I steer with my feet tho.
That's quite a nice idea, yes! I wish I had rudder pedals. I'd still need my hands to paddle though which would mean I wouldn't be able to steer with the remote as it stands. But I will file that one away!
When mounting the servo gear to the servo plate, whatd you use? M2.5 bolts and nuts? I saw in another comment that you used the rubber grommets that came with the servo, where'd you use those? Thanks for everything youve done modifying this for the watersnake, itll do me well!!
I used M3 hardware from memory, the grommets fit in the servo's mounting holes and the screws go through them into the mount where they are anchored with captured nuts. Good luck! :)
Thanks so much :) Originally I used the FlySky FS-GT3B RC car remote but I've recently switched to this cheaper, 6 channel unit. It has cruise control which is very handy. www.aliexpress.com/item/1005003753015123.html
One of these: www.aliexpress.com/item/4000764834254.html I got the 5A, 10-72V to 7.5V variant. Works perfectly and is waterproof as a bonus. The ESC takes up to 75v also, and puts out 5v for the receiver. All up pretty simple wiring. I am now using this controller too: www.aliexpress.com/item/1005003994231921.html
Could you please link me to the ESC you used? Seems like it was a good choice. The 5v output is extremely helpful for the Arduino. Does the voltage need the be regulated before the ESC or does it take care of that for you?
Heya, so I used a flipsky 75v VESC compatible ESC from these guys. The exact one I bought isn't available any more but any of the chunkier ones will work. flipsky.net/collections/electronic-products If you're in the States this might be a better alternative though: spintend.com/collections/diy-electric-skateboard-parts/products/single-ubox-aluminum-controller-80v-100a-based-on-vesc For 14S you need 75v and the ESC will regulate it for you. For 12S and below a 60V VESC compatible ESC will work. Other considerations are how to make them waterproof and cooling. Good luck!
I am about to give this a go for my Watersnake T24. What kind of programming did you have on this? The original design mentions programming software. Thanks
1) What battery do you use for the reciver? 2) The motor it 12 volts? 3) Do you use a regulator of speed bettwen motor and reciver? It Will be of good use a video about this información.
1) the main battery, the speed controller has 5v output. 2) normally this motor does, in this video I am using 50v. 3) yes, I suggest you watch the entire series, or at least part 2, 3 and 4 :)
I used M3 2.5mm button head hex bolts - not sure what length though sorry. Probably around 15-20mm but you'd have to measure to see what fits. Captured nuts in the slots of the 3d prints. I also used the rubber grommets that came with the servo.
@strepto42 Any way you could make a quick 3 minute video showing the ASSEMBLY camera on your hands so we can knock this project out with less guessing and questions need to see how all the 3d files are put together ... please
I'm having a little trouble tightening the shaft gear tight enough to the shaft so that it doesn't move. Did you have to glue or tape or anything to keep it still? I'm using M4 bolts and nuts and even then the thread will pull or the bolt will turn before it's tight enough
Yes I had a lot of trouble with this. I used some bear tape at first and small amounts of heatshrink as spacers but even that moved. In the end I drilled a small hole and fixed it to the shaft with an m3 screw on the non-gear side. It hasn't budged since. For a lower power motor the tape should be adequate but for my high powered motor it just had too much lateral torque esp when steering under power so the screw became nescessary. I never bothered to revise the print; I just drilled it carefully and made sure the hole was slightly smaller than 3mm so as to let the thread bite the aluminium.
The motor shaft needs to rotate inside the server mount, that's basically why :) The top gear of course must be fastened to the shaft itself in order to turn it.
Would be cool if you added a FC board and then could set gps waypoints for autoguidance. You could have ultrasonic collision detection and avoidance too.
@@changeagent228 Haha not sure if I'd trust it without quite a lot of testing! I've had some setbacks lately but the game plan is still to have inav going eventually. For now I'm concentrating on getting the system stable with the new giant motor (vid to come).
I wish you could show each step in assembling clearly. The speed of the time-lapse makes this impossible to follow especially for younger people. If you could sir post a quick video showing assembly to the motor part by part screw by screw THAT WOULD take alot of stress out my life. Thank you
Heya, sorry it's hard to follow. I haven't the time and resources to re-do anything in detail unfortunately. I'll look at the time lapse again and see if I can post it unlisted slowed down or something, maybe that will help...
@strepto42 I finally got everything put together for some reason my wheel doesn't spin freely to turn the shaft. When I attempt to turn left or right my servo just move in place stuck. Any tips?
@@BolowArizona hmm it's a bit hard to pin down without seeing what's going on. The shaft should rotate freely inside the servo holder without the gear attached. The gear part must hug the shaft tightly. Are you using the same model motor? I know some motors have slightly differently sized shafts...
