American Civil War City Class Gunboat

[Rad_Schuhart]

Lord knows I hate boring you fine folks with my gunboat project but I have the rudders set up properly now and here’s a short video showing how they operate. Some may enjoy this more than others.

This is not boring at all! I enjoy a lot new projects. Furthermore, not only I enjoy it but I need it! Sometimes you get bored seeing the same tanks again and again, so this is a very welcome refreshing breeze.

Keep us updated! I am looking forward for seeing it sailing!

Glad to hear that. Thanks guys. Last night I received and used the marine grease to add to the stuffing tubes/propeller shafts and mounted the motors. It’s now ready for a water test and maiden voyage.

I have kept away from this project primarily because of my abject failure in all things maritime but boring NEVER, More strength to originality on the Forum,
The American Civil War just like all wars that preceded it and followed on advanced science and engineering exponentially,
How would the most successful Submarine service in WW2 have got on if it was not for the sometimes successful and sometimes tragic Civil War efforts in advancing the silent service,
The most successful submarine service in WW2 was not Germany by the way it was the USA who unlike Germany's efforts to starve the UK into surrender did bring Japan's economy to its knees.
Great progress Jimster I come to this late but I shall stay to the end,We all know your staying power so this could turn into a saga lasting longer than the original unpleasentness

[Jimster]

Thanks, jarndice! The originals were built much faster than mine. Here’s some pics of the mounted motors and my awesome grease gun.

Long time, no update. I found out that my big servos for the rudders would shut down my Beier board if I turned them port and starboard too quickly so I have smaller servos that solved that problem. Then my tiny 16 channel receiver would shut everything off if my radio got within 3 feet of it so I’m about to receive an FRSky 16 channel receiver to replace it with. Still need to transfer settings from my old Radiomaster TX16 to my Radiomaster Mark II radio. The project is crawling along but my mojo ebbs and flows.

If you actually need the big servos you can run them directly off of a battery source or BEC and just connect the signal to RX. A lot of RX are limited by the amount of power they can provide to servos. I had a 1/4 scale servo used to fire a paintball marker in my combat tank. Using a direct battery feed solved the problem of not enough power.

I just started with overkill too big but the smaller ones seem fine. No more overload. Thanks for the tip though.

Sorry for noticing your topic late...
I am not a tanker (this is just for fun), I am a ship modeler with a lot of experience, but this is poetry...
I saw your coupling connecting the motor shaft and the propeller shaft and I will say only one thing - this is the worst idea bought on Ali.
The spring will unwind at the most inopportune moment, I did tests and as a rule this happens, because it is twisted in ONE direction and if this is according to the rotation of the shaft, then it still works, but in the opposite direction (and you have one shaft rotating in the opposite direction) the spring will simply unwind.
Use either a cardan joint or a rigid one.

[Jimster]

I will search for these joints you speak of. Thank you. I have zero experience obviously.

Yes, you can use ONE steering servo, I have one that controls four steering wheels and the power of the mini servo is enough, this is not a high-speed model, where a standard servo with a large load moment is required.
