Mini Quad Build > Sub 250g Quadcopter Baseline

This guy on youtube video served as my baseline for my attempt for a sub-250g quad build.
His weight estimate from public data sheets looks like this:

Descriptions		Qty	Unit Weight g	Total Weight g
DTI Blade 150 Frame		1	21.5	21.5
DYS 1306 3100KV motors		4	12	48
DYS SN20A ESC		4	7.6	30.4
CC3D Flight Controller		1	9	9
OrangeRx R616XN Receiver		1	1.4	1.4
Micro FPV camera	Eachine 600TVL	1	23	23
Video Transmitter	Eachine ET200	1	15	15
Batt	2s 700mah	1	46	46
HD Cam	Mobius?	1	45	45
Fluff				2.7
Video Baseline 242g				242

However, if you look closely, some components are missing but the still makes weight, like props, wiring, FPV TX antenna, PDB, etc.  This leads me to think published weigh values are overweight.

I choose to begin with a Diatone Blade 180mm frame, because I like to use full size 4" props.  I don't plan for an HD recorder for my first quad build but I want to run 3s batt.  There's not much weight margin to spare.

Trying to meet this sub-250g constraint makes this quad build so much more challenging.  If no such constraint, a 250mm class quad would be easier and slightly cheaper.
