Probably everybody. The BEC is only rated for 10 cells.

Hmm, I thought there was a mod you could do.
I ran my Quark with a BEC without making any changes.
I see in the instuction manual that the OPTO Modification says to disconnect or remove the the middle red wire from the pin of the receiver socket.
This may be a dumb questions but ,what does removing the red wire do?
