“KV” indicates the number of revolutions per minute (rpm) a motor turns when 1V (one volt) is applied without any load (e.g., propeller) attached to the motor. For example, a 2300KV motor powered by a 3S LiPo battery (12.6V) will spin at approximately 28,980 RPM without propeller...
“Tuning” is the term we use in the hobby to describe the process of adjusting parameters like PID, rates/expo, and others to achieve desired flight characteristics. This is an important step in optimizing your FPV drone’s performance and getting the most out of your flight controller.I ha...
I recently returned to O2, but for many years I’ve been switching between the likes of Three, BT Mobile and Smarty in order to pay less each month. Yet in all that time I was still able to access the freebies on offer via O2 Priority thanks to this trick that means you can get ...
In the US, the standard household current is 120 volts. However, that power level can be affected by numerous factors both inside and outside your home, causing both dips and surges. Lightning strikes may be the cause that leaps to mind, but more common are surges from brownouts, blackouts...
The arrival of a lightning bolt is an unmistakable phenomenon: a flash of light illuminates the sky as a buildup of electric charge connects with an object to release 300 million volts of electric potential—that’s enough to power 25 million 12-volt car batteries. This kind of energy is...
September 23, 2015 at 8:18 pm if you have a 12 volt battery you can charge all 1.5 volt rechargeable batteries, just line up 8 of them on series + to – and + t – and then hook to battery. take a paper towel tube and slit it, roll it tighter so it fits d or c or aa or...
