Door Frontier09/01/2016I bought five of these (one to have as a spare) to be used on my Tarot 280mm build (also bought from Banggood) with EMAX 2204/2300kV motors. Items arrived in time, they are genuine EMAX ESCs - you scratch the security code and it verifies on the EMAX validation application - they are running BLHeli 13.0 (the ESC labels mention OpenShot support). I use the BEC to power my FC from it and the whole setup works great.
A reliable choice.
