    [:)]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?

    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?

    Have no idea on the ESC but I think it's a Viper marine ESC? I was thinking of using this NAGATO as a runner. What ESC do you use on your I boat Tugs?

    You could run all four shafts on 2 motors with BC 1 input, 2 output gearbox.

    Curt;

    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.

    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.

    that sounds like it might be easier, esp if its only a model, not an RC NAVAL COMBAT MODEL

    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.

    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.

    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.

    Does anyone sell these, or do you have to make one yourself?

    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.

    im not planning on making one. I am using a 1input, 2 output BC gearbox for my Admiral sheer.
