Since a turn hs two components - bank/roll and pitch - which isn't working? What do you mean when you say "When I try to force it to turn..."? Is the plane banking left but then rising, or is it not banking? Can you get the plane to do a roll? Both directions? On ground check, are you getting equal deflection of the ailerons in both bank directions? Do you have suggested elevator and aileron throws?
