Opinions on the DasMikro 2S6A ESC

[TeamSeismic]

Hi Roboteers!
What is your opinion on this ESC and does have a built in BEC or a way of stepping down the voltage from my 7.4V LiPo?
Thanks.

Thanks for the quick reply, I'm a complete beginner to this hobby and from what I gather your quote recommends a resistor for each motor but I don't quite understand how this would step the voltage down for the receiver?
Thanks for helping out and sorry for my ignorance haha.

It has a built in regulator.

In my post you can see I talk about the resistors in order to generate a braking effect for the motors. Without this the robot is much harder to drive. That part doesn't have anything to do with voltage regulation.

By the way, I soldered a resistor on each motor, as recommended on the other thread. They're getting really hot, though--pardon my electronics ignorance, but is this normal? Okay?

They'll get warm, if they're getting too hot though just increase the resistance a bit. It's not an exact art, the lower the resistance the more aggressive the braking but the hotter they'll be.

There appears to be three variations of this ESC, which would you reccommend and which resistors do you think would work best?
Thanks.

Option A, and as I wrote in the post about resistors I found 50 Ohm to be a good option.
