not even the expensive throttle i have has such a feature. some, the x52 for example, have fixed detents which give you a tactile friction when you are in the afterburn or reverse thrust zone. however ive yet to see a game that uses it as such. my ch throttle is just a smooth linear motion without detents. id like to see a throttle with detent switches, when toggles a mechanism would add friction when the throttle crosses that position. with about 8 or so of them you could set them for anything from race car shifter to reverse-forward-afterburn.
my ch script costs me about 5% of my range of motion just to have the afterburn and reverse, and i have no axial control of reverse. i could probibly use the bottom 10% as its own axis, but the game would need its own reverse thrust axis for em to assign it to.
