Either way I agree with iceMAW, It should be like a gas pedal.

 the cougar has excellent trim functions. this is my hat 4 config:
BTN H4U   /U /H Trim_Elev_Up
                 /M Toggle_Icons
                 /D /I HOLDTRIM (JOYSTICK)
  	            /O Select_Engine_1             
BTN H4D   /U /H Trim_Elev_Down          
                 /M /H Trim_Elev_Down             
                 /D /I {TRIM (JOYX, 0) TRIM (JOYY, 0)}
	            /O Select_Engine_3             
BTN H4L   /U /H Trim_Aileron_Left          
                 /M /H Trim_Aileron_Left             
                 /D /I LOCK (THR, LASTVALUE)
	            /O Select_Engine_2             
BTN H4R   /U /H Trim_Aileron_Right          
                 /M /H Trim_Aileron_Right             
                 /D /I UNLOCK (THR)
	            /O Select_Engine_4            
so, if I set the dogfight switch on the throttle to D, and hold S4 button down while pressing Hat4 up the position of the X and Y axises are held until I press S4 and Hat4 Down. I have the same for to hold lock the throttle when bombing, so I don't accidentally change speed...
