well done!! in my opinion the perfect model doesn't exist, the only thing you can do is get very close to it. Your boat works very well, and the fact that the 1/72 scale with uboats doesn't offer much space certainly didn't help you, but you knew how to work very well. Congratulations for the "lego" choice... I would never have thought of it😊

Thanks! Yes, 1/72 is certainly very tight, especially for submarines of this type. I have a Type VIIC of the same scale that I’ve yet to convert!

Brilliant job 👏🏻👏🏻👏🏻

Excellent workmanship .

Wow!! Incredible hunk of work there.

Fantastic!

Beautiful 👍👍

Nice work

Great video, Subscribed.

This is very cool and well thought out. I learned so much about these rc submarines.

@@neitoRC it sure is. I fly rc planes and helicopters and absolutely love it.

Brushed motors are fine in water. We used to break then in in a cup of water. Rust is the issue. Brushless motors usually come anodized so they don’t rust as quickly

some simple one way valve will stop the water going back into pump. , i use nitro or gas fuel ones , also on larger models they work great for air storage to surface any time . always room constrictions.

There are float valves that will prevent water from going into the air intake line, the challenge is always fitting components like that in such a tight space. I will still go with a water pump conversion purely because of its simplicity and reliability.

Very nice, but I do have a major question. Do you have to have an antenna above the surface? If not, how deep can you submerge and still have effective radio control?

I am controlling the sub on 75mhz which penetrates the water up to at least 1.5 meters. I’ve never gone deeper than that due to weeds and visibility.

Neito Rc is back!

As usual, very nice presentation Nate. Will try to copy your Type IX when it comes to building mine.

Thanks! Working on modifying the WTC into a vented ballast tank system. Good old reliable water pump.

How are the Lego U-joints holding out? How about the BL motors, any problems running them wet?

@neitoRC

Lego U-joints are running fine, BL motors are perfectly running in the wet. Routine lubrification is needed, just like with cup seals and Simmerings.

Great job! I have the same model, a polycarbonate tube, and all the electronics for two years. Your video motivates me to catch on with the project. I also fancied putting the motors outside. I also have brushless ones, but inrunners. I’d like to go as deep as 6m with a 900MHz radio. Will see if that works.

​@@ocsimano729most RC subs run at periscope depth with brief excursion down averaging around 1m maxing out at 3m. Beyond that is crush depth. Even if your WTC doesn't implode there's the risk of seals leaking flooding the wtc. Also your wtc gets compressed so much that all bouyancy is lost even if you blow ballast. How will you see to steer at that depth? Unless you're in a swimming pool or have a camera connected topside via cable you're not going to see anything.

try putting in end of air pump tube a fitting like you find on a snorkel mask. either that or replace the pump with a co2 cartridge

Exactly what I was thinking. Seems a bit lame to go through all the effort to make a functioning submergible system and use a 10” snorkel. So many ways to make a true air ballast system.

So you can't fully submerge ? The tower has to stay above the surface to re-emerge

@neitoRC

10 күн бұрын

it can fully submerge using speed and diving planes, but the boat is set up such that there is always slight positive buoyancy that brings the boat up to the surface. The snort ballast system requires the snorkel to be above the water for surfacing.

on you water tank why dont you have it setup to just pump in water and let the gas compress

It’s a 3D printed ballast tank so not really safe to be pressurized from the inside.
