This seems to be a next generation re-branded YEP ESC with several differences to the older YEP and Rotorstar series. It has a finned heat sink, 12 amp vs. the old 6 amp BEC which is selectable from 6 to 8.2 volts for HV Servos, It also has a big capacitor on the other side that you can't see which probably does something the old ESCs did not do or it prevents bad things from happening. Not sure. But be aware that it means it will not sit flat on a surface.

I'm hoping for some good durability. My YEP 100 amp ESC was great until I changed the PWM frequency. That change "chirped" or de-synched the motor on throttle up and the ESC was dead after that. Motor made a screech sound. Motor was fine. Esc looked fine with nothing burnt but no beeps. No beeps means nothing is getting to the motor. OOPS! Tried to re-flow the solder for the SMT chips in case anything was loose and actually got some functions back but never could get the motor to beep or budge.
One thing about these ESCs with the programming card. The programming card lets you do lots of stuff but be careful. With great programmability comes great risk.
