ESC 4in1 choice

[nicesub]

Hi All,

I am all new to this stuff. At the moment I am waiting my first "starter pack" FPV drone. Meanwhile, I am putting on the paper my first custom drone and browsing around for information.

Anyway...I am going for 3.5" frame and settled on Flywoo NIN 1404 V2 3750KV for motors. I am looking at their charts and I can see that each can pull at worst 10A so 4 of those gives in total around 40A.

Now coming to ESC, I want 4in1 solution and the confusing bit is their spec sheet. When for example they say that a 4in1 ESC is rated for 40A, does that mean 40A in total for entire ESC board, so basically each ESC on board can handle 10A? or is this 40A per each ESC on the board?

Also if my setup is expected to pull 40A on the motors how much of headroom I should look for in ESC to be safe? 45A ESC setup would do?

No you got a small detail wrong. When it's a 4in1 esc the amp rating is per esc so a 40amp 4in1 can actually pull 40 amps per so 160 amps if you add it all up.

40 amp 4in1 is overkill for 10 amp motors but it will work. Just don't want to use escs the are rated less amps than the motors pull unless you want bad things to happen lol.
