The Lumenier F390 20A BLHeli OPTO ESC uses the powerful F390 processor giving you faster motor repsonse and tons of power. This 20A is super small weighing at only 6g and smaller than most other ESCs. The 20A power rating makes this a perfect ESC for smaller aircraft like the 130-210 sized quads. It comes pre-flashed with the popular BLHeli, and the firmware is easily upgraded to newer versions in the future. Oneshot and damped light is enabled by default, and it can also be flashed with Multishot.

This ESC makes it easy to solder your motor wires by extending solder pads out past the heatshrink. No need to cut back shrink and remove factory cables, just simply cut your motor wires to the desired length and solder directly to the ESC.
