As long as you use the correct frequency range for your model. If you have a radio with a (Aircraft freq), you should convert your transmitter and reciever to a (surface freq.)

Radio Frequencies

Aircraft Use Only (72 MHz)
(72 megahertz, Channels 11 - 60): This is the most popular choice for flying models. Most radios designed for model aircraft and helicopters will be available on these channels.

Channel / Frequency

59/72.970
60/72.990



Surface Use Only (75 MHz)
(75 megahertz, Channels 61-90): Cars, boats, and other non-flying models must use one of these channels. Pistol grip radios are available on 27 MHz as well as 75.

All Uses (27 & 50 MHz)
(27 megahertz, Channels A1-A6 and 50 megahertz, Channels 00-09) While legal for air or surface use, we recommend that 27MHz be used only for surface models. A pilot and driver broadcasting on the same 27MHz frequency would cause interference and could cause a crash. 50MHz channels can be used for R/C, but require the user to attain a Technician-class amateur radio license from the FCC.

In order to allow the prop shaft to go through the hull (like real ships) we use what is called a "stuffing box". Some have also called a "stuffing box" a "stern tube".

The stern tube is simply a tube with bearings on each end that support the prop shaft. The stern tube is filled with oil (thicker than water) or grease. The oil/grease prevent water from leaking into the hull. The drawing below shows a stern tube I designed for my USS Crockett to prevent "spider" cracks from the props thrust pushing against the prop strut. The grease fill tube is used to maintain grease in the stern tube.




In real ships, at times water does leak from the stern tubes. This "leak rate" must be kept within specs and is greatly reduced by the crew maintaining proper alignment of the stern tube and prop shafts. In my models I have seen a drop of two seep into my hull at the most. If you keep the shafts in aligned and the stern tubes filled with grease, leakage of water is not going to ever be a problem. wink.gif

Hope this give a quick answer to your question.

You have asked a good question. There are quite a number of model fourms out there today on the net. For example, one that I am a member of and highly recommend is http://www.wmunderway.8m.com/cgi/yabb/YaBB.cgi. This board is for those who enjoy warship models. This board is run by Kurt Greiner and he asks you all to remember that his discussion board is for Warship models, not a general place to post photos of any boat or ship model you happen to have. While he does enjoy well built civilian models too, he tries very hard keeping his website and forum on topic. Even if you do not have a warship model, you can read the posts and learn alot about the hobby. wink.gif If you are a member of another board, we hope that you continue to support them.

MODEL MARINA DISCUSSION BOARD

This board is set up to cover the "Scale" R/C model boat and ship hobby. This covers scale fishing type boats to scale tugs. Scale model warships are also an item that even I have a few projects on the building tables. I don't tend to be as strict to the type of models as long as they are scale in nature. biggrin.gif

Here is a quick tip. When you finish with your models clear coat them with a "flat" finish. This makes them look more real. When they have a "gloss" finish, they tend to look like TOYS. wink.gif

Dumas uses what is called a variable resistor style speed control. This type of spped control is far less effective and effeciant than an ESC. Plus, using a Dumas spped control, if you do not have the control set to off (slider in the midle) it will drain your battery and you wouldn't know it!

Can anyone tell me where I can get a couple of the 3700 series Pitman motors that are widely used for the Mr. Darby Tug? Where can I get them and what is the cost of these motors each? I have a 48" inland water way Tow Boat ( barge pusher) that I have built from scratch that needs a couple of monster motors. The boat has 50lbs. of balast not including batteries and other RC gear and running hardware. I am currently using 2 Pittman 9000 series motors but the dont seem to be as big and powerful as the 3700 series motors I've been hearing about. The boat is very nice and I have spend probably a couple hundred hrs on building it, but it just doesnt have the power I want it to have. Any info on where to find a couple of the 3700 series Pittmans would greatly appreciated!!! Thanks - Ben bolin03@hotmail.com

Try Dave at http://www.harbormodels.com/. I'm thinking he still sales them but am unsure of the price.
