Nothing much to say about this build. i need to switch out motors to check out different motors.
I post it up with PID so if i ever want to put these motors back on i would just use the PID.

they weigh about the same as 1202.5/6 motors. they fly like 1202.5/6 motors.
they're not strong enough to spin 3" tri-blade props
On 2s, it's slow with 5500kv but my yard is small, so it works out fine.
On 3s, it's a bit too fast for my yard but should be fine if fly in parks.

it's efficient at this 5500kv, means longer flight time.
they're a lot weaker than 1105/1204/1303.

setup:
46g dry + 31g 2s 650mah HV
frame: babytooth 2mm ( 3mm if you want more durable )
ESC/FC: happymodel crazybee v3 ( if you want more range, don't use built-in RX )
motors: happymodel ex1203 5500kv
props: gemfan 3018
VTX: pandaRC vtx 16x16
camera: Caddx Ant Lite

Tune:
2s ( in the picture ), move P and D slider down 2 or 3 notches if you want to run on 3s
use toothpick preset from UAV Tech ( https://theuavtech.com/presets/ ) then appy PID
