I have a 35% extra, was running a menz 27-10 2-blade on a DA-100. Rudder trim seemed perfect. Switched to three blade for noise purposes and have done nothing the change the engine thrust but I notice it isn't the same as with the 2-blade, particularly in inverted up or down lines (cuban eights & goldfishes). Here is the test I performed to prove to me something is not right:

Few directly into the wind, away from me, straight and level the plane flies striaght. Pull up to 45° and it continues striaght, roll inverted on the 45° up-line and it goes to my left (planes right) do I need to add or reduce my right thrust? Or could it be something else?
