I have had them operate in opposite directions, and I have had them not spin at all, and even in flight had then all spinning like fire works.
What I want to do is press a button and rotate the servos from one position to another; ideally Id like to be able to rotate them as desired in either direction, pointing back to pointing down should suffice.
What I managed to do was use "custom one" and "engane servo motor" and set the target angle BUT I never managed to actually do it from the VAB. I could build half the command in the VAB, assigning the one key to engage motors, and in flight set the target angle, then I could hit the one key and they would switch from thrusters pointing back, and thrusters pointing down. this is very hackneed.
It's so buggy. Like the adding the target angle in flight didn't stick, so everytime I would load a quick save the changes would be lost and THIS IS INFURIATING when trying to land.
