self.__moveScale and self.__turnScale are private to the FlyNavigate class and when you try to set those in your MyFlyNavigation class your are creating new instances of them and so the viewpoint is not affected.

When you call the sensitivity method it works

vizcam.FlyNavigate.sensitivity(self, 1.0, turnScale)

but by passing in a 1 you are re-setting the moveScale valueback to its original value

keep track of both moveScale and turnScale in your class and then pass them both to FlyNavigate.sensitivity

def __init__(self):
	# Default movement keys
	vizcam.FlyNavigate.__init__(self,'w','s','a','d')
	self.__moveScale = 1
	self.__turnScale = 1

and then you can set each value individually and pass in the value set before

def setMoveSensitivity(self, moveScale):
	self.__moveScale = moveScale
	vizcam.FlyNavigate.sensitivity(self, self.__moveScale, self.__turnScale)
	
def setLookSensitivity(self, turnScale):
	self.__turnScale = turnScale
	vizcam.FlyNavigate.sensitivity(self, self.__moveScale, self.__turnScale)
