The unit is indeed very small and light. It is one of the very few lightweight ESCs supposedly able to whitstand more than 3A.

*However*, the unit I got simply could not drive an OverSky AP 05 5000 Kv efficiently on a single LiPo cell.

The max amp draw was about 2A while it should have risen to 3.5A.
The ESC got pretty hot, presumably triggering overheating protection and thus limiting power to about 60pcnt of the actual motor capabilities.

Besides, the beeper would work erratically (sometimes fine, sometimes barely audible and sometimes plain mute).

Finally, the spec is *wrong* about programming, as other comments/reviews have already reported.
The actual programming options are limited. Notably, there is no way to reverse engine rotation without physically inverting the wires.

Very small and light regulator. Many available settings even to set them is very tricky. But when you realize how its very quick.
