First time build help

[nickxab]

Hello to the team !

I recently got from a friend an Eachine V-tail 210. He crashed it and he never repaired it.
The flight controlled is damaged so i'm searching for a flight controller and a PBD.

I have 4 x Emax lightning-20A ESC
Specs:
Continuous current : 20A
Burst current : 30A(10s)
Li-po battery : 2s-4s
Multishot, Oneshot125

4x Emax RS2205 Motor
Specs:
KV : 2300
Configuration : 12N14P
Idle current(10)@10V(A) : 0.35
No. of Cells(Li-po) : 2~4S
Max. continuous power(W)180S : 135
Internal resistance : 118mΩ
Max. current(180S) : 12A


I was thinking to buy the HAKRC F722 D Mini F7 Flight Controller.
Specification:

Brand: HAKRC
Item Name: F722 DJI 45A Stack
Packing Size: Φ62*33mm
Stack Weight: 25g
Packing Weight: 30g


Flight Controller:
Processor: STM32F722RET6
Gyroscope: MPU6500
BEC: 5V/3A; 9V/2.5A
Storage: 16MB
Input Voltage: 3-6S
Firmware: Betaflight_4.1.0_MATEK722se
Uart serial port: 5


ESC:
Continuous Current: 45A
Maximum Current: 50A (Sustainable 10S)
Assistant Software: BLHeliSuite
Input Voltage: 2S-6S
Drive Signal Support: Dshot150/300/600, Multishot, PWM, Oneshot.

What i can't understand is the current distribution. For example in the one i want to buy it's 45A but does this means it's 45A for each ESC ( 4 x 45A) ? Or it's the total current ( ESC1 + ESC2 + ESC3 + ESC4) ?
I searched on google but i found that both are correct and it got me really confused.

The 45A is the maximum current the PCB can sustain no matter how many moror(s) (up to the 4, of course) are pulling amps through it. Your 210 is highly likely not capable of pulling anywhere near that much current so long as all all 4 motors are undamaged.

Thanks for the reply ! If i understood correctly in burst mode these motors will draw 12A x 4, that’s 48A should i get a 60A just to be safer ?
Sorry ! To many questions i know it’s my first drone build.
