When you are operating your RC boat, a controller unit will be required with batteries and a receiver. There are many different brands of controllers that include such names as Futaba, DX, IFH and many more. Some of these brands make controllers for both boats and cars. There are different types of controllers, first I want to mention the 2.4 GHz controller. This controller will ease your mind about any interference from other units being used in the area. Another plus with the 2.4 GHz controller is you no longer need the long whip style antenna. The older styles 25 MHz to 75 MHz controllers had the possibility there maybe someone else in the area using the same frequency you are. If someone was running the same frequency as you there would be many control problems. The 25 MHz up to the 75 MHz is a much lower radio frequency then the 2.4GHz. This means the lower frequencies are limited to fewer channels. When using the 2.4 GHz you will have a high frequency controller with more channels. When using this control unit you are going to find directional controls as well as adjustable options for the speed of your radio controlled boats easier to adjust.
When you get your new boat with the 2.4 GHz controller you would be well advised to take this controller out with your RC boat to a safe area. Then proceed to practice with it until you get an understanding of how the boat works. In most cases after some practice you will be able to maneuver better and you will have a better idea what the absolute limits are before your boat will no longer operate as well.
The next thing to keep in mind when you are working with remote control boats is you need to understand the water option that you have available to you. Total area available and hazards in the water are going to need to be taken into consideration when you are looking to use RC boats in certain areas. When you are looking at your options, remember that standard RC boats work better with smaller bodies of water like small to medium size ponds. Small to medium size ponds generally have smooth water. Larger areas such as lakes and rivers have rougher water to navigate. These larger water areas can benefit the larger and faster gas and nitro powered boats. Depending on the model and size of the boat you have on the larger water areas will determine how they will cut through the waves and currents of the much rougher water area.
