@BraceMaker Pardon my lake of servo knowledge. I guess my thought on the throttel control was the driver could overide a few ways, pulling the throtte back, pulling the safety lanyard, or hitting the stop button,
If you get a hard left or right rudder that is unexpected, I was thinking getting tossed out of the boat. If safety can be built into this then I agree if you have crappy drivers in your group, by all means have at it.
