Why You Need A RC Power Supply

What does a DC power supply actually do?
 It plugs into the AC power in your home and converts the higher voltage down to 12volt DC high amperage output power for your RC battery charger, or whatever else requires a low voltage DC input to work. If you already have an AC/DC charger you will not need a power supply as these chargers have there own built in power supply to feed the 12volt requirement of the charger, but these chargers are usually not intended for fast high amperage charging applications.

Why are some chargers only DC?
This feature allows the manufacturer to dedicate all the room inside the charger to do the job at hand, and still keep the charger compact. Typically, most DC only units will charge at a much higher rate than AC/DC chargers.

Why would you need a 24 volt power supply?

Nearly all high-end battery chargers do not plug into a standard household 110 volt AC power outlet, they are designed from the ground up to run off of 12volt DC power source such as a 12v car battery, as with the most high-end chargers they are very capable of operating from 12 to over 32 volts DC and with good reason. Lithium based batteries have come a long way in the last 5 years. In the past, 1 hour charge rates were the norm for these batteries, but as technology has advanced, so has the ability of these batteries to be fast charged. It’s not uncommon to see Lipo batteries designed for a 5C charge rate (roughly 12 minutes), with others rated up to 15C (roughly 4 minutes to charge!).

Understanding ESC Setups / RC Hobby Shop

Ever wondered how to get the best performance possible from your brushless RC project? Matching up your electrics could be one of the simplest ways. If you’re making a vehicle from scratch, or simply wondering if there are any improvements you could make to your RTF or RTR vehicle’s setup, then this is essential knowledge. There are a few rumors and misconceptions out there, but if you let us set you straight, then you’ll be running a top class RC vehicle in no time.


When starting this prosess, you want to start by looking at your motor. Is it the kind that the manufacturer recommends for your vehicle? Or, if you’re putting your RC plane, truck, or heli together from scratch, is it the kind generally recommended for the type and size of vehicle you want to make? This information is usually available on vehicle packaging or in instruction manuals, listed as the kV rating (for example, 3300kV) and the size (length x diameter). You might not always be able to find a perfect match, but if the motor is as close to these requirements as possible, then you’re off to an excellent start.

Farmer Not Waiting Around For Gov. Regulations on UAVs

By GOSIA WOZNIACKA, AP WRITERThe Daily News Online                                

Farm dronePORTLAND, Ore. — Idaho farmer Robert Blair isn’t waiting around for federal aviation officials to work out rules for drones. He and a friend built their own, outfitting it with cameras and using it to
monitor his 1,500 acres.
Under 10lbs and 5 feet long nose to tail, the aircraft is the size of a turckey and Blair suses it to get a birds eye veiw of his cows and feilds of wheat, peas, barly, and alfalfa.FULL STORY HERE

Brushless RC servo
I came across this article about servos and how they work and thought the analogy and the principles he conveyed were fantastic. So I had to post it in it`s entirety for all the RC flyers out there to read. It covers everything very thoroughly...enjoy this great read, I did.

By: RC Helicopter Fun
RC servos convert electrical commands from the receiver back into movement. A servo simply plugs into a specific receiver channel and is used to move that specific part of the RC model. This movement is proportional meaning that the servo will only move as much as the transmitter stick on your radio is moved.

The Latest In Quadcopters

These RC Quadcopters are going to be the most well reviewed and best rated quadcopters there is in the market. We note that while the term ‘RC Quadcopters” usually refers to toy radio controlled electronic flying devices, we are also going to be talking about and reviewing some larger models of unmanned aerial vehicles which have high technology surveillance abilities using HD Cameras like the Hero 3 to capture very precise pictures. Those types of applications are probably going to be something that the US Military, specifically the US Air Force are looking into.
