What I found that helped with the clockwise rudder drift (of course set the rudder trim on the four-in-one unit [carefully] fully left) power up the transmitter with rudder trim on the transmitter fully right. Then connect the battery to the 4-in-1 and start flying. If the rudder drift resumes eventually clockwise again (it probably will) land the heli , and with the transmitter still on disconnect the battery from the 4-in-1 and plug back in (with the rudder trim on the transmitter fully right) . The problem is at least temporarily resolved. I tried trimming the upper blades back a bit as someone suggested, but without results (Is the decreased upper blade thrust offset by increased upper rotor speed increasing the torque?) Don't have the spare parts to experiment. Also any ideas on how to widen and lengthen the stance of the landing gear without using training gear? On a snapped post on the landing gear I found that a snug fitting section of heat shrink tubing carefully heated makes a great splint. (the kind they use to insulate spliced wires) PS don't forget to slide the rudder trim tab to the left as needed for newbies newer than I am.
