That's normal!!! Sounds like your are moving the sticks before lift off. Plug in the battery and place heli on a level surface. Now when it comes online it remembers the level part. Next DO NOT move the sticks except the throttle unitll it lifts off. Now you can start to input sticks. If your heli rolls over like you said, then it needs to re-learn level. Unplug the battery and start over.
Hope this helps, I love my Mcpx.
