I find that besides the F4U, the I16 is super aft, the hurricane, the Mossy and B25 all have you sitting back too far. Instead of removing the headset to stop tracking I found a much easier and more effective method.
NOTE: This applies to Oculus Rift (my setup)
1.) Take mental note of how far you would like the Aircraft to slide back or forward to put you in the sweetspot.
2.) Press the Oculus menu button on the right touch controller. (Even if you use your HOTAS). Pressing the Oculus menu button pauses your game and gives you the option to "reset tracking" or "Quit Application". Using your touch controller, point and click the reset tracking option. It will then tell you to look ahead and press any button.. BUT WAIT.. DONT CLICK ANY BUTTON YET.
3.) if you were set wayyyyy back in the pilots seat like FLS mentioned in the F4U, simply slide your chair back a few inches, or lean back a few inches and THEN CLICK ANY BUTTON TO RESET TRACKING. Then return to your normal sitting position.
You will find that the plane has now slid back and you are now in the sweetspot. You can use this method to adjust the plane in any direction you want in order to position the cockpit perfectly to your taste.
An example, In the B25, the default position has me too far back and too low. So I quickly hit oculus menu, click reset tracking, lean back and stick my head up, tap any button and boom, im in the sweet zone..
occassionaly the tracking will reset or drop an inch or two for no reason and so even mid flight the option i described above takes me less than 5 seconds to reset.
Hope it helps..
