OK, I try to explain, but it´s difficult to get the correct technical terms in English. It´s all improvised with DIY superstore and bicycle parts. The whole TQS body is fixed on one of my WheelStandPro bases, in the middle of the TQS side cover there is a simple bolt (for wooden doors...) fixed ( position of all parts improvised , just trial and error), the spring of that bolt keeps it downwards. I cut a kid-bicylce brake lever into parts and made a cable of some (trial and error) length, which is simply attached to the bolt by a green fence wire. If you pull the shortened brake lever, the bolt comes up. The detents are put on the base plate with instant adhesive, meanwhile I improved the metal stop for the AB detent with a bigger, ascending metal block. I fixed these detents (always trial and error) at a position, that you cant´t go to cutoff position without pulling the brake lever (cutoff release), but you can go over MIL to AB, by just kicking forward over that metal block. The resistance is much better than that small plastic noses which are integrated in the TQS by Thrustmaster.
Well, in XXX Sim it was possible to make the right settings, where the TQS throttle meets MIL and cutoff position, you even could make settings for hardware only cutoff position. I didn´t have seen that complexity for DCS settings, so I have to look, how the detents and positions are manageable with DCS Vipers. I hope that helps....
