For all the engineering crap that gets spouted and always funny to see some people cling to academics like its the next coming of Jesus.....what matters is how the actual plane responds in real life. A lot of cases, as has been attested to by a great number of people in this thread, what works in theory isnt what works at the field. Some planes react better to toe-in, while others may be OK with a touch of toe-out.

And yes...there IS a debate. Someone claiming there is no such debate because of what they believe, doesnt make it fact that a debate doesnt exist. Some people find toe-in works for them, while others find toe-out works for a particular plane better. Whatever.

I prefer tow-in as it works on the planes I fly.
