Im building a Des Moines and looking at the prints it shows that both propeler shafts are on one side of the ship. Does anyone know if this is correct or if I'm just looking at it wrong?
It has 4 propeler shafts. 2 on each side of the ship. Your print is probibly showing only half section with the assumption that you know that it is is "typical". Most people just drive the center 2.
Okay I thought it was weird to have them on one side. the hardware kit from BC came with two prop shafts and to motors so I'll run it that way. Thanks
Most clubs require that the unused shafts be there too. They don't have to rotate, but they need to have something on them that looks like a prop.
that's easy enough to do. They dummy shafts don't have to go thru the hull and I can even set them up with props that turn to prevent drag.
Dummy shafts do have props on them that do not turn. They are called "Drag Props". I am told that they help the ship in turns.
Yup, since our ships have top speeds and we use the thrust from the props to turn drag is actually helpful since it lets you have more thrust and hence better turning.
I currently battle a Des Moines. Position your drive props as close to the rudder as possible to help with turning. She is not the best Turning ship out there, but if you battle her right you should not need to do heavy turning. Seriously Drag props are a help, but if you can Combine that with Drag Disks as well. I am about to make a new set of Drag disks for mine to go on my dummy shafts as I have changed my pinions some give more thrust so I need to slow my ship with some drag disks more than my Drag props do currently. Good luck on your build.
How many ribs do I need to have when cutting the windows in the hull? What size do the windows have to be? I was going to go as far down as I could on the windows so that I know that I am well below the waterline. I know the min is 1" below.
Check out the Port Polar Bear web site's construction articles. There are examples of rib layout's in a couple ship close to the same size as yours. http://www.portpolarbear.com/reports/index.html You should end up with 23.85 1/4" ribs. Don't cut the windows all the way down. You will not have to. Your ship is allowed to be 17 pounds. But should come in around 15-16 pounds. So put enough stuff in your ship so it weights 16 pounds. Put it in the water so it sits level and mark the water line. Cut 1" down from there. OR find someone that has the same ship that is finished and ask them were the window is. Take a messurment every 3"-4". OR go by the real waterline on the ship plans. It's pretty close. When you get done if you need to cut down a little more (1/8") just do it the first time you resheet. Rookies get a pass if they make a minor mistake like that. Before you cut it out make it with tape and post a photo, then we can give some advice. It's all on the DVD.
okay. the dvd was awsome!!!!! It has helped me a lot and has already saved me time and money. Every rookie should get it before they start their first build
