Pitch up moment sometimes

[Zaretto]

[Octal450]

I'm looking at this, its due to the G control being "surprised" by the sudden change in actual G due to rolling with the high roll rate of this plane. I think I can fix it by leading the G in the proper direction.

If you are talking of the pitch up tendancy when leveling after a turn, this is most certainly due to the lag filter applied to the pilot pitch command.

The filter output won't be at 0 just after the turn, even if the stick is neutral (and the tighter the turn the higher the filter output will be).
