Jim when you set it up I would do this.

Goto the advanced menu and then GYRO SENS
Set it to ON
Then Rate UP Nor 50
Rate DN Nor 25

That will give you normal mode 50 percent and 25 percent gain. Make sure CH is set to whatever you have the single wire plugged into, usually 5 and SW is set to a toggle, I use F but thats on the H version, whatever works best for you.

Take off with the gain at 25 and see what happens. When you get in the air try the switch and see again. If nothing wags land and try a takeoff at 50, you can keep bumping the gain and seeing what the most you can run is. Where you will see it start to wag is at higher speeds so carefully feel these out. When you get it to do what you want go back into the gyro menu and set the other side of the switch to the same number but AVC. You will see what I'm talking about. I'd always make sure you would takeoff in Normal mode then you can experement with heading lock mode in flight at a safe altitude but I think you will find you are using normal mode most of the time.

Let me know if you have any questions.
Have fun with it!
