I have been using TIR 5 + Track Clip Pro for a couple of weeks. I think it is brilliant but I'm still a long way from getting the settings as I want them. The main problem with the software is the absence of being able to simply set a maximum field of view for each axis. It can be done but it takes an awful lot of fiddling with graphs and speed and particularly for the 180 x 2 views getting the speed right is hard. The big problem when flying and moving around is avoiding joystick movement. I've augured several times while looking back right due to pressure on the stick. Having said that, I use very sensitive stick settings.
Observations :-
1. using a stick button for TIR 'pause' can be hit or miss and need to be pressed more than once. Oddly 'centering' works fine from a button.
2. Still puzzling over this one but sometimes I go into Zoom mode for no particular reason.
3. Some custom sounds seem to upset it.
4. aiming when it is active is very tricky even with large dead zones, particularly when zoomed. To get round this I have set KP8 to highest seat setting and fully forward (see 5) and programmed a stick button to a) pause TIR b) move mouse cursor to center screen c) engage KP8 view. Result is that the mouse pointer becomes the sight because the normal one has disappeared due to high seat and I can see over the nose better. This can and is often done without TIR of course. Unfortunately, problem 1 (above) can leave me stuck there for a vital few seconds!
5. I run AH at 120 degrees FOV on a 20" 1600x1200 monitor. This has the effect of moving me back in the cockpit and also giving good six views.
One thing is for sure. I'll never go back to button views.
