To program the failsafe, you go into "F/S" in the basic menu. Cursor to the channel you want to set. Move the appropriate stick to the position you want the control to be in when it goes into failsafe. While the stick is held in that position, press the dial until you hear a small two-beep tone. Move on to the next channel. When you're done, hit the "END" button or turn off the transmitter. The settings should remain for that model.

We double-checked with one of our transmitters here, and had no difficulty.
