ESC,bec

[918mike]

Alright guys have a question iam not 100% about still.do I need to purchase a bec when running an opto ESC? This is a whole new world for me from my heli and I keep second guessing my choices.

IMO the best way is to use a power distribution board with 5V and 12V built in regulator. Just use the 5V out to power your flight control board.

Yes. This one has all good reviews and it's the same brand Painless360 often used in his tutorials. Claims to be shielded.
