LittleBee 30A S ESC BLHeli_S have all the performance you would hope for and the same tiny size as the DYS BL30A.
You will struggle to find a frame small enough to fit these ESCs and they will still give you plenty of headroom on a standard 250 size quad!
These ESCs do not have a BEC, you will need to supply 5v power to your flight controller with a UBEC or stepdown voltage regulator.
Oneshot125 is a different and faster communication protocol between the flight controller and the ESC on your quadcopter.
It allows the FC to send control commands to the motor quicker, therefore in theory your multirotor should perform better.
Damped mode With the BLHELI software rapidly evolving, you can flash the lastest firmware using the 3pin connector and suitable USB adapter
and now can be used via the cleanflight GUI please note you will need to be running the Betaflight firmware to connect via the cleanflight interface
but this is a simple way of adjusting and tweaking the settings of your escs.
