The answer is NO. They are programmed for each function of roll & pitch. They also have different part numbers. AND, P3P numbers are different than P3Std. BTW, the yaw board is in the upper main board & is totally different.
Thanks a lot jiminyfixit, I found the cable connectors were broken so I checked the pot resistance at the top solder pad and the bottom left and right solder pads. They were 358 and 368 so I will take these good pots off and put them on the boards with the bad pots.
