opto or bec esc's?

Posted by Sigmund Martinsen on November 10, 2013 at 11:26pm

Hi,

I'm building a hexacopter based on the Mikrokopter Hexa XL frame with T-Motor 2814 710 kv motors. I will use APM 2.6 with the power module. Now I'm into choosing the right esc's for this setup and have a question regarding the right esc setup:

Is it necessary to have a separate bec to power opto esc's if I use the power module (jp1 removed) or will the power from the apm be enough (no servos)?

(Any other good tips about choosing the right esc is appreciated)

The BEC or 3DR PM would power the APM/electronics. OPTO's get their current from the battery directly - they do not need to be BEC'ed themselves.

I use Tmotor 30A OPTO PRO's; they weigh and are the same size as much as a conventional 2-4S ESC, but are rated for 6S.
