The fourth flight concentrated on gear retraction. I flew around Mt. Wachusett for half an hour at 120 mph (level flight) and 100 mph (climbing) and put the nose gear up and down three times at each airspeed. I found that there was a small change in pitch trim (nose down) with gear extended, and a small change in airspeed. Neither of these things is a big surprise - the gear hangs down below the CG, and has a modicum of drag associated with it.
You can read the Flight Test Protocol for Flight 4.
I combined Flight 4 with Flight 7, since they're both pretty short, and 7 isn't dependent upon 5 and 6.
