I have the t link software working fine in DCS as the virtual toe brake. I'm sure AH will work the same way just haven't had the time to set it up here yet.
Map a button on the software so when pressed it tells the game to engage the virtual axis its something like Joy RX/ RY to be mapped in game (for planes that have Left and right brakes).
What it does is engage wheel brakes when pressed, then when your foot pushes on the rudder bar it drops that wheel brake axis to 0% rather than 100% so I can just press and hold the mapped hotas button, feet down on left pedal and I get the plane going the way I would with toe brakes. You still have rudder authority at all times just when you press the brake button it puts whatever side your foot is applying brake down. You may have to invert it if it doesnt go the way you want it too.
your only really using it when coming to a stop, taxiing or spinning on the spot. In DCS it can get a bit tricky as the spitfire doesnt have differential toe brakes so you just have to tap the button more frequently to not tip the nose. I dont think AH models that in the spitfire here.
Sorry if the explanation isn't that clear when learning / reading how to do it I think everyone just works it out and comes up with a different answer. All I know is that it works fine and your not at all losing out by not having toe brakes.
The software needs to be running just minimize it and click it to green in your toolbar.
