The first popular use of radio control systems in models began in the early 1950’s with single-channel self-built gear… commercialized equipment followed later on.
In the 1990s miniaturized equipment became widely obtainable, permitting radio control of the most small-scale models, and by the 2000’s radio control was commonplace even for the control of low-priced toys. Prior to radio control, numerous models would employ simple burning fuses or clockwork mechanisms to control flight or sailing times.
Typical radio control systems for radio-controlled models utilize pulse width modulation (PWM), pulse position modulation (PPM) and more recently, spread spectrum technology, and trigger the various control surfaces using servomechanisms.
Thanks to the advent of Modern powerful electric technology, today’s electric boats are accessible in larger scale models providing motors that can maintain lightning quick speeds.
Just like when you purchase a new car you have to break in your radio contcontrolled boats. What you do is make certain that the motor is not under load ( not attached to anything). Oil up the bearings well with a silicon or find machine oil and then connect the motor to a four cell pack and let it run for about twenty minutes. Then shoot them with a motor cleaner and then reoil.
Breaking in the motor is more important if you have a high RPM or high torque motors. To break in these motors run them on 6v for twenty minutes after oiling them down really well.
Powerboats of various types make up the lion’s share of RC craft. This group can be divided into two classes: sport boats and racers.
Sport boats are fashioned first and foremost to be entertaining. This takes a back seat to functionality. Sport boats are in all probability the better choice for novice modelers, as they are designed with an eye toward simple and dependable performance with a healthy dosage of speed mixed in.
Racing boats are more unyielding and, consequently, more temperamental. These boats are the fastest, but they are also the most high-maintenance and the most difficult to drive.
Many people are opting to purchase electric boats, as there is a good deal less upkeep to do .The biggest drawback is that electric boats gets slower as the run time progresses and the battery power is exhausted.
Most serious hobbists go for the gas and nitro models as these babies will require 
much more tweaking, and if speed is your thing …go nitro.
The one thing in common with all types of r/c boats… They do not tolerate “sea weed” in the water. The majority of radio control boats use rudder and propeller systems that are submerged fairly deep into the water .This can be overcome by the new flying boats that utilize out of the water propellers for propulsion.
So wheather you like to take it easy, or forever trying to break the speed record
( it’s around 140 mph!!) this is a very high form of recreation that everyone can enjoy.
