ESC's and UBEC's


JFreeman

Recommended Posts

In the past I have always used a separate BEC rather than the BEC in the ESC. I am in the process of putting together another 6 channel model. The ESC I propose to use has a built in 5.5V/6A switching BEC. Can somebody please give me the pros and cons of using the built in BEC rather than a separate BEC.

Thanks for your help.

For starters, 

Pros: saving weight, space, cost.

Cons: If ESC fails, then the BEC part could well fail too, leaving you with no power at all. 

I've thought about this too, and await others reponse with interest.

This subject was fairly well covered in this recent thread which is worth a read if you have not seen it.
