r/rcboats

first time running my 73” still some work left and for 3/4 throttle not to bad and im happy how she runs.

I own Arrma vehicles and looking to get a boat to use at our local lakes

So I got the boat out on the water for the first run. It floats … great. But i had a hell of a time trying to get it going anywhere fast. It was just super loud and could hear the prop sucking air. I think it’s a weight problem so I’m moving batteries all the way to the back and esc but am I missing anything else ? No trim tabs right now fyi.

What’s the problem , I’m assuming need more weight in the back. I got up to 75% throttle on 6s and the thing wouldn’t move. Check my profile for more details.

I recently finished designing my first RC/3D Print project - a radio controlled tugboat with functional azimuth thrusters that rotate 360º.

Both the controller and the boat are powered by ESP32 using NRF21L01 radio modules for communication.

My initial thinking was to use joysticks to control the thrusters but after thinking about it decided they wouldn't be ideal as they snap back to center when let go. Instead I used rotary encoders to control each azimuth thruster independantly. Turning the knobs on the controller sends the angle data to the tugboat which then turns 2 stepper motors to match the angles of the knobs.

During testing I quickly realised that without being able to see the thrusters and their current angles it made controlling the boat much more difficult. This is because it takes some time for the thrusters to catch up with the angle set on the controls. To solve this I added an OLED screen to the controller which gets feedback from the tugboat to display the actual angle of each thruster on the screen.

If you're iterested you can see the code on Github (https://github.com/stuartbnz/ASDThrustersESP32) and download the STL files for free from Printables 😁

Its suppose to connect with the apprentice but idk how to do. i have tried everything and got to know that apparentely my spektrum is us patent and my apprentice eu. the issue is idk how to install a eu firmware in my dx6. i have a project tmmrw and need help asap for this.

My newest RC is a scale Panga with a Yamaha F200. It still needs paint but I ran it for the first time yesterday. It just barely had enough power but runs at a good scale speed.

Next is speeding it up...

Hi everyone,

I have a Volantex 791-1 (RG65) RC sailboat. It was accidentally put in salt water and stayed underwater for a few seconds. After that, it stopped working.

I replaced the servo, battery holder, and receiver. At first it worked again, but then it randomly stopped working.

Now, when I put the batteries in, the receiver light turns on, but the servo does not respond. It looks like there is not enough power going to the servo or something is still damaged.

Do you think it is worth repairing it further? If yes, what parts should I check or replace?

If not, can you suggest a good RC sailboat around 400€?

Thanks!

So I got an old school Prather 40” Deep Vee and last season I ran it I was using hatch tape but it’s such of a big hatch that it uses a major amount of tape. And where the tape seals is in a super inconvenient spot. I was just wondering if anyone had any other ways to seal the hatch. I was kinda thinking of using some window foam tape around the edge and some body pins or something along the lines of that.

I made a 3d printed paddle steamer and i got myself a piece of solid metal, whould this be enough to bring the water line to the paddles?

Just got this great little boat called a Proboat Recoil 2. It has a black foamy/rubber seal which kind of works, but water still gets in.

Is there a grease of some kind that I can put around it to make the seal better? Or waterproof tape I can put over the top when all sealed up?

What is everyone else using?

This year we go for 6S instead of 4S. Enjoy fellas.

Is it possible to build an RC Seabreacher e.g. in a scale of 1:7,25 (70cm length) ?
