That's a pretty good idea to start a new thread.....

As far as the heli yawing clockwise, it sounds to me like your gyro is backwards. Since the main blades turn clockwise as well, you can rule out the the tail rotor itself. There should be a switch on the gyro that is labeled 'tail-lock'. Use a tiny screwdriver to switch it over and see if it rectifies your problem. Also, make sure you get a better charger for those batteries. I guarentee that you will fry some batteries sooner or later. The Walkera charger is crap. Also, make sure your xmitter batteries are always fresh. Change them after about an hour of flight time. This will save you from some nasty nosedive, kamikazi crashes.
