Hi, I have the Emax Simon Series 30amp escs on my F450 quad, it says in the instructions that it actually has BLHeli firmware. I am not sure which Esc option I should choose with my CC3D and the refresh Hz rate as I have searched everywhere and cant find this? Can someone please recommend. I chose update rate at 490hz and PWM using Spektrum Satellite.It seems to fly ok, escs are a bit warm but not hot after 12 minutes of flight I have the Emax 2213/935 motors as well but am concerned I may burn the escs out, thanks in advance.
