HobbyKing Mini 15A ESC

In one of the recent emails from HobbyKing they announced the new HobbyKing Mini 15A ESC. This is the first DIY:ish ESC from HobbyKing (I think) which has no cables soldered and no heat shrink applied. It is perfect for the builder who always de-solder the leads anyway. What is also peculiar is the voltage rating: 2-6S. Does anyone really believe that this $7 no-name ESC can pull 20A at 23V? Maybe it can.

My personal interest in the device is whether it is a budget alternative to ESCs like the KISS in a mini-quad or maybe a mini tri-copter build. In terms of power specs it looks good but there is no information on the firmware and no information on whether is can be re-flashed with BLHeli. And if it will survive operating with soft dampening.

From what I can see now there is only size that is comparable. So I pulled out what I had. I would have preferred a comparison with the Afro Ultra lite, the KISS and the EMAX BLHeli 12A but they are all installed somewhere. And this is what I had...

As you can see, size is not an advantage. It is small, but excluding the capacitor the EMAX is smaller. And the KISS is even smaller. I'm afraid this product is a no-go. I won't buy any more of them. The choice will still be between the EMAX, the Ultra Lite and the KISS.
