Prior to the flight, adjusted the rudder trim tab out a little more. If it proves to be flexing, I may just go to a wedge like is on the other guy's plane in my hangar. Pulled on the flaps - yes, the right flap definitely has more "give" than the left one. Nothing to do about the give, but be careful with the adjustment so they both end up at the same place in flight. The little flap gap seals against the fuselage should help with that, when I decide to add those. In flight - did a brief run up to 165 indicated and did some gentle turns. Feels very solid at that speed. Slowed down and collected airspeed cal data at ~2400 rpm and ~2000 rpm. Pattern was quite busy on return, but it was nice to push the nose over to get some speed to squeeze in, then slow down to 80 to match the plane in front.
