And the Tbird has this very long fade portion thats at least 30% of its flight. Its not a huge left turn, but it fades for a long time.
factor of nose angle, power, and breaking it in.
on a 20' high nose down line drive a teebird will only fade like 20-25'.
with a disc like a wraith on a 20' high nose down line drive (with under 450' of power), it will fade like 60-80'.
