Hi Steven,
Thanks for the quick response. I'll try to record my next flight, the issue is that you would need to see my joystick input as well (otherwise it just looks like im pulling hard aft on the stick at that point in time) so I'll see what I can do. What is happening is that I'm keeping a constant back pressure on my physical joystick to pitch up towards the flight director and it suddenly pitches up on its own more than I command just for a split second which is about right after the gear has retracted and the aircraft is at about 15 degrees of nose up pitch. All of this is happening with the AP OFF while pitching up slowly to follow FD for NAV and SRS, I realise that I also always set the accel to 3000ft instead of the default 1000ft the recent flights, so the aircraft is in NAV SRS with manual flex (AT on) when this happens, hope you can manage to reproduce this!
EDIT: I purchased the A340 today (amazing addon!) and it is also showing the same nose up behavior on takeoff
