All AW139's 4 axis equipped I actually fly and the only 4 axis Bell 412Ep I flew had FTR on the pedals.
As Maeroda says, however on the 139 you have to apply equal pressure on the pedals for them to release properly and the microswitches can get a tad sticky sometimes.
Remembering that the aircraft has yaw trim above 41kts accelerating and kicks out below 45kts decelerating.
