jubalr, i am totally with you here, as I took my solo out tonight and easily replicated it, but only IN to the wind. With the wind pushing down, along with the pitch it was too far down and caused it to drop like a stone, even though i was only doing 30 mph.
Was going over 50mph in the other direction with very little drop in altitude.
So yeah. im ok with the explanation given, but that does not absolve 3dr either. They need to make GPS mode at least fail proof from this respect. Whether that is limiting things further, or whatever with sliders, I just know whats going to happen "BUT I WAS IN GPS MODE" and they are right. GPS is beginner mode and under no circumstances should it diving that quickly (and it is possible in gps mode).
Im not happy either way
