Yes I am running a 2s setup in a Hyper 10SC with a JR 9100T servo , tried a cap and it didnt work , went too a external BEC and the cutting out went away but it still didnt run the Ballistic 550 motor right , I would get this weird cogging when going slow around corners no matter what settings I would try .

The Havok Pro SC ESC is running the same setup with no problems at all .
