Thanks for the link to the setup information. I will go thru the whole thing and check the alignments. There has to be something out of whack..it is way too unstable to do much with. Even the gyro gain and rotation adjustments seem to change with every flight. My CX2 is so stable, by contrast, that I can lift it off, set the transmitter down and walk away..and it will hang in the same spot until the battery runs down. Now I don't expect that kind of stability from the CP, but total random behavior is what I have now.
