Multistar ESCs and Multiwii Pro 2 problems

Hi everyone,

I have 4 Multistar 45amp ESCs. I upgraded from a HK 2 board to a Ready to Fly Quads Multiwii Pro 2 board. I have one SBEC ESC and 3 OPTO ESCs. Only the SBEC will initialize and work on the Multiwii board. They all work fine on the HK board.
Doing research, it seems that the ESCs need the + pin to be in parallel between all the ESCs and apparently they are all independent on the Multiwii. Does anybody know if it is possible to program the + pin to work with these ESCs? Or is there something else going on here?

Any help is appreciated.

I have them working. I pulled the red wire from all three of the OPTO ESCs and connected them to the red wire on a BEC. They all arm now. It seems like they need the 5v connection before initializing.
