I can't believe anyone would take an aircraft up knowing such a problem exists. He should be certain his ailerons are properly balanced as well. As far as the pitch trim is concerned, his is not an uncommon situation. I assume that the nose up trim is just sufficient for slow flight. My 235 trims at 100 mph with the flaps in trail and at full aft pitch. With flaps deployed, I must hold back-pressure to maintain 100 mph on approach. Full nose down trim is needed with 1 passenger at cruise (200 mph). 80% nose down trim is sufficient if I'm alone in the plane. Taking some reflex out of the flaps in cruise will reduce the forward-pressure needed if your nose-down-trim challenged. I give the flaps a short blip out of reflex to permit hands off flight at cruise.
