You need to have launched with a GPS satellite acquisition. I think you need to be in GPS mode but not sure why atti would not work. But GPS mode works for sure. So...right switch to the top, left switch to the bottom (HL), Left stick at about 50% throttle, more if you think you are low, right stick pegged on the bottom. It will be overhead shortly. Practice these steps before you need them. Practice each day. It will save you multiple times. I wish someone would have stressed it to me.
