How to use an external power supply instead of batteries with ESC and brushless motor?
Recently I have made a remote controlling system for my friend's RC plane, the problem is we want to test it on the ground without batteries..
So, I told him we can use an external power supply that gives 12V, but we can't calculate the needed amperage(? A) ...
We'll be using EMax 18A brushless motor + Emax 30A ESC , all of these are using 11.1V, so what and how can I calculate the needed specifications of the required power supply ?
I wish you could help me, and thanx :)
