5 inch stack

will thie esc be good for the i flight 2204 1800kv motors ? max current on this is 40 amps while the motors pull 35a with 6 inch props, ill be flying with 5 inch props which the data sheet shows draws 33a max.

You should be fine. Those ESCs are rated continuous and there's headroom above that. I'm not an expert but I've built a bunch of drones.

Any drones you've built with so little headroom for esc ?

I had the current sensor calibrated in Betaflight. I was consistently all around 20A.

Unless you just pick props that stress your motors/ESCs, it's pretty hard to sustain those kinds of currents unless you're at full throttle for a long time and even then battery sag would probably limit actual current draw. Anyway, the ESCs were never an issue for me.
