 | | 06 Nov 2008 11:33 AM | | [:)]I was thinking of outfitting Nagato with 4 motors running 4 shafts. If I was to use direct drive what size motors would work for a boat this size? I think I will be using a ESC on this. If I do use an ESC with direct drive how many ESCs do I have to use?

 | | 06 Nov 2008 11:43 AM | | Don't know for 4 motors, but I routinely run 2 motors with one ESC on my I-boat. What ESC (and what ratings) are you looking at using? | | | Battling: SMS Scharnhorst, SMS Baden
Building: HMS KGV (Drives, pumps water, guns are in but not plumbed)
MN Edgar Quinet (Hull done)
Drydock/Mothballed: Rus Evstafi, DKM Lutzow, HMS Invincible
Plus 20-odd other projects, according to my Boy Scouts who thoughtfully counted them for me. | |

Why would you want to run all shafts? Sounds like it would cut down on turning ability?

Hi Marty. I am using this Nagato as Non combat so turning won't be an issue here. I am building it for scale and detail. Like to have it run all 4 prop. ADM Stokomoto | | | Bismarck

 | | 07 Nov 2008 07:35 AM | | Curt, if you are going for scale, have you thought about building yourself two belt boxes rather than gearboxes? They will be quieter on the water and are rather easy to make. | | | |

 | | 07 Nov 2008 12:26 PM | | heck, I recommend belt boxes in general as they are, when constructed right, a bit more forgiving on the drivetrain when you hit dirt/rocks in the shallows and are quieter. | | | |

 | | 07 Nov 2008 12:46 PM | | Hmmm belt boxes. I am not a big fan of belts but for Nagato it may be doable as I wouldn't use it that often. I don't have the resources or knowledge base to build one myself.

 | | 07 Nov 2008 12:57 PM | | It is easy. Pick the right timing belt (sdp-si.com) with sufficient tooth height for what you are trying to do. Biggest issue is if you need a large amount of reduction... then they get too big. then make certain your motor can slide to take up the slack. | | | |

 | | 07 Nov 2008 02:38 PM | | No one does that I know of. I generally make them myself. They are less tolerance sensitive than gearboxes which makes them a bit easier if one wanted to make it truly by hand.
that being said, if you are running 550's heavily geared down, the gearbox is probably the better option. I tend to play with motors to find some that only need a little or no gearing down (or gearing up in some cases) so that I don't have the very high speed components in a ship that make some of the annoying noises. | | | |

This may be a non sequitur.. but since I have been reading this and that and looking at this and that.. But could you not feasible alter the rates of the different screws to help in turning? Granted that would mean two different ESCs. Especially if you have 2 rudders it may not be as fast a turn but tighter turn? I thought some of the full scale ships utilize screw speed to help in turning as well or am I mistaken? If that is true then is our scale not as impacted by it as larger scales?
