Dji 30A ESC Opto


Junior Member
I´m looking at some new esc and don´t really know what opto does. The only thing I know is that it´s no bec built in instead it´s opto but what are the main benefits in using opto esc?

optoisolated speed controller might be necessare in some cases.
- if you have a lot of servos and other things making a built in BEC to small capacity.
- if you are running your motor at a very high voltage.
- if your motor could cause noice back on the cable to the radio rx.
perhaps more reasons.
