Good day all

So far, when I was building quad-copters with a 450 frame , I have been using the BLHeli32 - 30A ( Hobbywing Xrotor ) ESC’s. It seems they are discuntinued and I now have to look for something else. I would like to stay with the Hobbywing. Seems to be a good choice.

The ones either side of the 30 A is the 20A and then the 40A ESC ( both Hobbywing )
The 20A is 20A continous ( peak 30 A ) and the 40A is 40A continous and 60A peak.

My setup is as follows:
450 frame
2213 (920kV) motors LDPower
9450 props
Pixhack V3 (FC)

AUW = 1.5kg
Some values when I hover:
CTUN-TH0 = 0.3
RCIN ( CH3 ) ( THR ) = 1400

CUR is at about 12 A ( with a small peak at 14A )

Would I be cutting it a bit close to use the 20A ESC ?? Would like to have some opinions
if I could.

Many thanks all !!
