Default gt5.1 on mini titan sport. tilting forward on pitch pump. [SOLVED]

I. Am am setting up a new mini titan s FBL kit. I have an issue with the heli pitching forward when i do a pitch oump. The heli hovers fine, although it seems like it needs some back elevator trim. I guesse the forward sip is probably present at hover. But not reaally noticable untill i pump the pitch a little.

P for swash is on 60%. Hover headspeed on about 70%.

where do I start looking? Just to confess. I am not too confident in FBL just yet. I know its the beez kneez these days. But i am yet to feel easy in trusting my whole cyclic to electronics that have a hundred parameters... I am a bit out of my depth in trying to troubleshoot this one...

on a side note. When sitting on the bench. The swaah drifts and dips slightly down and left (front). I am batyling ti understand how I am supposed to check if the swash pitches up evenly.. when I am not in control of it...

I would really appreciate some ideas...

For someone else's possible future benefit, I found the issue. The swash was totally whack out of being level... the elevator servo was way off. I thought the swash was creeping, it wasn't really. It was just the elevator being so far off. It was a complete spline turn off centre. This is hidden in the air, as the FBL gyro will keep it hovering, and not falling forward as with a flybarred heli...

Have to give it a test fly, but feel much better about it now.

For reference to guys getting this kit, it may be a good idea to see my post on everything that was a bit whack with the assembly of my (A)RTF kit.
