 Flick the switch on your remote powered vehicle toy and watch them go. An RC electric motor may not provide the raw power that a nitro one does, but it is more quiet and cleaner.
 
There are two basic types of electric motor for RC cars and trucks:

~Stock motor cannot be changed in any way. It comes from the factory and must be used as is. When you buy a ready-to-run electric RC car or truck, then the motor that comes with it will be the average stock motor.
~Modified electric RC car motor is typically more powerful and must be used with a separate electronic speed controller. It has adjustable timing and ball-bearing races.

electricrcboats-airlandseahobbies.jpgThe hobby of collecting remote controlled toys can be addictive. It is thrilling to see your toys race and gather speed whether on land, air or water. Electric RC boats make for great summertime fun for the whole family. The boats are easy to control and don’t require any special skills to know how to make them move.

While you’re engaged in your big-boy toy, let your kids play with their own little boats. These small RC boats can be played with inside the bathtub or in a backyard kiddie pool. Hear the children’s laughter and excited chatter as they have fun with their small group of maritime fleet.

Lipo Batteries are a great source of power for everything in the Electric RC Hobby. The question occasionally comes up about Trickle-charging Lithium Polymer Batteries. There are many good reasons it is not a good idea. First it is unsafe to charge any lipo battery unattended, to trickle-charge you would most likely have to charge it over night or for some extended period of time. Trickle charging then violates the first rule of safety in charging lipos, NEVER LEAVE THEM UNATTENDED while charging. Something could happen to the battery causing it to vent and Catch fire. it could be as simple as a household pet knocking the battery off a shelf or knocking something onto the battery. To safely charge lipos you need to be able to monitor the charge so you know they are progressing properly.

Some of the other problem are that most of the chargers that are marketed for lipos are not set up to trickle charge. Lipos can and should be charged at up to 1c most chargers have an automatic time cut off to protect from over charging. It is always best for safety, the batteries life and capacity to charge them with a balance charger.

Never try to trickle charge a lithium polymer battery, it just goes against all the known safe charging principles of lipos
