autopilot makes only very shallow turns

Hi
Is there a way to increase the bank angle set by the autopilot in the VSKYLABS tecnam on X Plane 12?
I could change the roll/pitch rate in the X plane settings but it's the trim deflections that allows the autopilot to make steeper turns.
Right now, I'm getting 5 deg banks max out of the autopilot which is unusable during approaches.

Note: I fly the Saab as well but its autopilot works perfectly in giving me standard rate turns at different bank angles.

THanks
