Some general 109 advice...
If you find yourself in a wings level climb and want to roll in on the lower fighter, always roll left if you have the choice. Torque can add a couple of seconds to a right-hand roll at low speed. Use torque to assist the roll by going left; much quicker and stable. Pay close attention to the flaps as they auto-retract quickly once your nose goes below the horizon. This means careful throttle management. When nose high, flaps full out, don't attempt to roll right with the engine powered up... It'll just hang there and rudder will not assist the roll. Either pull off throttle or, better yet, simply go left instead.
