So today's post was made possible by @SnipeHunter and BrianK.

I've been looking to optimize the acceleration and maneuverability of Idaho, and ran across a tweet from the USNI (the folks that published Tom Clancy's Books) explaining how prop blade count works for 1:1 scale ships, and the primary example given was the SoDaks (not the fantasy football SoDak, the SoDak that should be 24 seconds SoDak). The North Cackalackas and SoDaks both had vibration...

Could someone give me a brief overview on motors so I can be more educated when shopping for the right motors?

I am also semi-shopping for a Bismarck but that is future build.]]> 8 Thu, 23 Jun 2022 02:09:03 +0000 https://rcwarshipcombat.com/threads/best-sources-for-motors-and-best-make-to-use.446801/ https://rcwarshipcombat.com/threads/best-sources-for-motors-and-best-make-to-use.446801/ invalid@example.com (Ironbeard) Ironbeard Seems that a lot of sources I knew from back in the day are long gone and a lot of closed down due to covid or are simply not taking any orders.

Back in the day we used Maxon motors but haven't seen any around or I may be looking in the wrong area.

Also what are the best size and make of 6v-12v motors for cruiser to battleship size Big Gun ships these days?

Best sources for builds: Balsa, electronics, gears, bits and bites?

All,

While this was revealed a bit early yesterday I thought I’d go ahead and make a dedicated announcement for it.

With the closing of PropShop this past year I couldn’t find a replacement source for cast bronze props suitable for our hobby. (My experiences with the cast “scale” props...

What size gears are best? Does the diameter dictate the tooth count? For example, I found a 2” dia, 46 tooth gear. Does that mean I need find smaller dia gears with the same tooth count? Or does the smaller diameter gear reduce the tooth count.

also what thickness of gear is the most reliable?]]> 4 Tue, 16 Jun 2020 12:08:11 +0000 https://rcwarshipcombat.com/threads/which-prop-for-these-shafts.446514/ https://rcwarshipcombat.com/threads/which-prop-for-these-shafts.446514/ invalid@example.com (Skeeterbug) Skeeterbug View attachment 22786 Hello all. I recently started building a USS Texas from a kit purchased from Strike Models some time back. I started looking at the drive system and decided to go with dual 5mm shafts driven by a pair of 550 motors. The problem I’m having is with finding appropriate props for the drive shafts I purchased off eBay (don’t hate, they were reasonably priced). These shafts have drive dogs on them for what looks like racing props. I don’t think those are appropriate for...

Which prop for these shafts?]]> 5 Fri, 13 Mar 2020 20:43:13 +0000 https://rcwarshipcombat.com/threads/angled-rudders.446436/ https://rcwarshipcombat.com/threads/angled-rudders.446436/ invalid@example.com (Caractacus Patt) Caractacus Patt Fuso and other ships, I've noticed that some have their rudders at at angle (from vertical):
View attachment 21665 What was the purpose in this, and has anybody done this on their boat? I was wondering what the effect would be at our scale; I'm thinking it would induce some (inward) roll as the ship turns - would this be good, bad, or indifferent? It might also allow the top of the rudder to travel closer to the hull, as the hull...
