Who's throws did you use? and how much Expo? Did you set the CG per plans?

Do you think the plane pitched down at full flaps due to the extended air brake action on top of the wings when the flaps are fully deployed? as you know, the take off flaps show very little air brake hence the pitch up, but at full flaps the top section of the flaps creats a lot of drag!!!
I used my own throws based on the throws in the manual. I would say a mix between the two. Recomended flaps @ 40 deg., a little less ail and elev than Marc with 30-35% expo. Felt spot on, just a little sensitive on the elev, but that will be OK when I move the CG forward. My initial CG was approx 2 cm behind rec. position and I think that had a lot to do whith strange behaviour with flaps.
