Hi guys yes as a newbie i have lots of Questions i dont intend to be annoying. When it comes to buying a controller i heard somewhere that you shouldnt buy the same set up as say an airplane as their frequency signal does not work as well underwater?? True? If so what sould i look for?. I want to run both planes independant. If possible throttle fwd rev and steering on one Joy and both planes on the other. At least two switches one for venting the other for blowing ballast. I Take it the servos usually come with the controller. >>>> Now power? Obviously with a large build comes large power needs. If i have to run 6 or 12V are there special cells availbale or are guys useing Say a motorcyle bat?>? My build will have the space for the size of a motorcyle Bat 2 if neccesary. Options??? Thanks for the ears guys id like to ask the dumb questions now and incorporate it into my build now and not find out later Doc

Hi Doc,
If your just getting
Hi Doc,
If your just getting started, there are a few things that you need to take stock of before you jump in with both feet. What is your level of experience with any kind of modelling? How much disposable income do you have to work with? It's much better to start with a basic radio control model rather than trying to go for a full blown, multi function boat with all the bells and whistles as a first effort. There are many people who try to make their first boat a gold medal winner, only to end up frustrated, broke, and sick of the whole hobby. You will get lots of help from this forum, but we need more information from you.
The "controller" is usually simply called a radio. In the U.S., aircraft radios are on the 72Mhz band, surface (boats and cars) are on the 75Mhz band. You don't use an aircraft radio for surface models because you can accidently end up crashing an airplane operating on the same frequency. That's how people can get killed or hurt. You will need a radio of the proper frequency band for each, both planes and boats.
Radios can be purchased with various numbers of channels, usually running from two to eight . Each channel controls one function. For a submarine, you will need around four or five channels to control rudder, dive planes, throttle and ballast functions. The throttle is controlled by an electronic speed control, called an ESC. the rest by servos. Some radios come with a full compliment of servos, some with a couple, some with none, but servos are inexpensive and easy to get.
Batteries can range from the sealed lead cells used in motorcycles to pretty exotic LiPo's (Lithium Polymer), which are expensive and more tempermental. Probably most people use Nickle Metal Hydrides (NiMH), which are a good middle ground between the two. Most people seem to use batteries that range between 7.2 volts to 12 volts.
My best advice is to join the Subcommittee, read EVERYTHING on this forum, ask many questions and talk to someone who actually has built an run subs, if possible. Be sure to set realistic goals too. A brilliant submarine modeller of top rank is right there in Victoria B.C. He goes by the web name of Bob the Builder, and you will find him on the membership pages of this forum.
Good luck !! -
Thnks Chuck I know what
Thnks Chuck I know what im in for and love the challenge, im actually also enjoying the research aspect as well, ive always had a thing for U-Boats and is nice to rekindle it again. DocComment
