Electronic Speed Controllers, in short ESC, are indispensable parts of FPV drones as they function to connect the flight controller to the motor. This component takes the signal from the flight controller and gets power from the battery. The main function of ESC in a drone is to make the brushless motor spin. Brushless motors canít spin on their own because they are devoid of brushes i.e. commutators -which provide the physical contact of motor windings to spin the motor. Therefore, brushless motors require the help of ESC to spin.

To buy electronic speed controllers for drone, you should know about how ESCs are rated.

How are ESCs rated?

The ratings of ESCs depend upon how much current they can pass to the motors. What ESC has to do is to switch power on to the motor coils at extremely fast rates. This switching is controlled through the use of microprocessor and carried out by transistors called MOSFETs, which are commonly known as FETs.

Amperage

How much current i.e. amperage can pass through the ESC is determined by the size and quality of these FETs. Most of the ESCs have ratings such as 30 amps or 25 amps. This magnitude generally represents the sustained current that an electronic speed controller can handle. For short durations, generally less than 10 seconds, ESCs are capable of handling more magnitude of current. For example, an ESC labeled as 30 ampere is capable of a 40 amp burst.

The amp rating is an important factor to consider when you buy...Continue Reading

No matter whether you have lots of experience or quite new to drone flying, it’s wise to take some and do essential pre-flight checks. This will help you ensure you have a successful drone flying experience, and is crucial for safe drone flight.

To help you have a great drone flying experience, we have curated a checklist of things that need to be done before each drone flight.

1. Check the functioning of drone - It is the first and most important action to take before the actual flight starts. Inspect your drone thoroughly, looking for any damage or error that can impact the functioning of the drone. Check for if your compass is calibrated and also your GPS connectivity is working properly.

2. Make sure remote controller is charged enough - It is the most important equipment and without it you cannot do anything about the drone. If it stops working, this will cause havoc on your drone. So before you go for drone flying, check for the charge of your remote control. Make sure it is charged enough. It is also better to get an extra remote control that you can use in case the one remote does not work.

3. Mobile Device is charged and has the Latest Versions of the DroneDeploy and DJI Apps - You will need mobile device with DJI apps if you are using a DJI drone for your flight. If you don’t have, get the latest DroneDeploy app and supported devices.

4. Ensure firmware is up to date - If you are using DJI drone, you will need a mobile device with latest drone...Continue Reading
