Bad Yaw Drive?

[FortisVenaliter]

In my PID for Yaw, the blue drive variable keeps spiking to what appears to be positive or negative infinity, which causes my thrusters to freak out which causes the process variable to freak out and make the whole craft very difficult to control.

I've used PIDs successfully before, so I don't know why this is failing like this.
I've triple-checked now that all the thrusters are correctly configured for their relative location.

Don't use the yaw PID. Don't use that one, the rest are more reasonable and roll is the only one with a high success rate. Reset the Yaw PID inside the mainframe to 1 deriv, 1 integral, and 250 for the final setting with set point off.

With a modified yaw PID, the vehicle begins to fail to turn, and will eventually default to acting as a stabilizer instead. It will make jerkier movements, not do proper dictated paths, etc. You won't have perfectly stable turning without making the roll PID compensate the los, but it's the only working way without making the craft bigger, heavier, and filled with more or larger control surfaces.

Pitch PID can be modified last for compensation. This is to be done after confirming roll edits and the yaw works, so if a mistake transpires one will know what is causing it and correct it. Wait until the yaw PID is fixed.

If you are turning out of control however, even after this, put more yaw surfaces on. Don't want it on the outside, put them inside as all control surfaces still function when enclosed. It could also be utilized as a form of marginal armor to set off APHE to save vitals behind it.
