    Has anyone used a separate RX battery as a backup for the BEC on a YGE speed controller?

    The manual says, if your using the 5.7 volt BEC setting, to just use a NiMH 4 cell battery directly into the receiver port.

    I would imagine the main reason for using this is incase your main battery dies or the esc over heats etc.

    Is a backup battery effective? or is someone better of snipping the red wire and using a separate RX pack and voltage regulator?

      Snipping the red wire and using a separate RX pack and voltage regulator, is how i went with it, back when i used YGE's

      If you use an RX pack then whats the purpose of the BEC?

      The using RX battery with BEC had me stumped as well.

      From what I have read, the RX battery is meant to be used as a buffer pack or backup. I suspect this is incase if there is some type of calamity with the ESC , the RX battery will give you servo control to auto rotate land your helicopter.

      However, in practice, I was flying a logo upside down when the ESC decided to go pffffft. I had a separate RX / voltage regulator for the servos.

      But, once I flipped it up right, it was over bushland at that stage, so I couldn't see it when it got behind some bushes, so I did damage it.

      In this case the separate RX battery and voltage receiver did kind off help.

      I suspect, regardless, of separate RX pack or not, if its going in, its going in.

      If you use a BEC I would always use some form of backup to make sure in the event of a esc/bec failure. I generally run a Backup Guard. The buffer pack can be used the same way, but it will also charge off the main flight pack... as well as being a buffer in the event of a huge current draw from the servo's.

      but except for my 450, if it runs a bec, it has some form of backup.
