Gugnunc, does yours have the newer 2.0 engine by any chance? Ours is the 1.7, where 50% is a mere 90 knots at 3.3 USG/hr. We need 60% (4.0 USG/h) for 106 knots but generally cruise at 70% (115 kts, 4.8 USG/hr).
Thread creep, I know, sorry. But the DA-40 is indeed gorgeous. Can't stop talking about it.
