Banggood

I received them with BL-Heli 14.6 and with a configuration for multi ( See the BL-Heli screenshot). I upgraded them to BL-Heli 14.8 (which was the latest version at that time) without any problem.

These are great ESCs. They are OPTOs, meaning you will need to power up the flight controller separately and not via the ESCs. They can take big bursts from a 4s lipo so you do not need to worry. They are a bit big in size, being 30A but they will not be wider than standard arms (I have them on my ZMR250). Best thing is to remove heat shrink, solder directly to motor and then do new heat shrinks.

They arrived in perfect conditions, all well packaged. I'm using them together with Emax 2205 red bottom <3

Sehr günstig, klein, Leistungsfähig und auperdem mit BLHeli Firmware. Bedingungslos zu empfehlen!

Really nice ESC's to pair with Emax RS2205 motor. The build is pretty good.

Super Regler

I use them with EMAX MT2205 II KV2300 RC. Cold and works perfect

All four working, will see in flight... Can not be flashed by DYS usb linker :-(

Excellent ESC

Funcionan de maravilla en mi cuadricoptero. Los utilizo con los motores Emax MT-2216.
