Its probably happened to all of us. In the early days of flying the Phantom can sometimes drift further than you planned and its hard to see which way its facing. If you have not enabled Naza mode then you will not be able to use the HOMELOCK feature to bring it back to you.

When the chips are down try these techniques to bring it home. They are demonstrated using the Heli-X simulator. Practice makes perfect and the best way to grow your skills is by using the simulator. I have posted a thread on Heli-X elsewhere in the forum.
