A109e has trim release on cyclic which also does trim release on pedals. This is a diabolical arrangement in my opinion. It should of course be on the pedal but there needs to be considerable finesse in how its done. Take the EH101 system for example. In this case it has 2 microswitches, one centrally mounted under each pedal face. To move the trim point you have to make the micro switches. However if your feet aren't central you are not moving the pedals..if you apply a lot of force (cos the pedals are locked in trim) then shift your foot slightly to actually make the microswitch the pedal moves quickly under that force. Also if your idle feet (great Autopilot) touch the pedals when the plane is flying itself suddenly you have control. Some aircraft by Airbus helicopters have pressure sensitive trim which I find much more seamless provided the chosen breakout force selected by the manufacturer is not too much and not too little.
