Blammo,
Expect 3 months of pain before it becomes second nature. Your gunna learn how to fly all over again.
With a hat switch you fly "from" the views because of the set angles.
With Track IR you fly "into" the views, so you lose your learned ability to fly the plane looking out at a specific angle.
Get some profiles from us that have gone through the painful setup, test, and retest phase.
