Kitfox SS7 just completed. Rotax 912 ULS

When I put in full flaps, I do not get enough electric trim to stabilize the plane at 60 mph. It is necessary to hold some backward pressure on the stick to get 60. I don't remember this being the case with either of the Kitfox's that I was trained in (stick & rudder aviation). Do I just need to go in and make an adjustment. Has anyone else run into this?

Thanks
