So I've seen videos about hand catching a P2 v1.0, and it seems easy enough as to turn off the props you just hold the stick down for 3-5 seconds (correct me if I'm wrong). But the v2.0 requires that both sticks be pushed down and in (toward the center), which requires 2 hands (for me at least). How are people hand catching their P2 v2.0s (if at all)? Also, I understand calibration should be performed on a level surface. But is it essential to take off from a level surface? I imagine it would be ideal, but taking off from the beach...the sand is rarely level. And I don't have a hard case (I used a backpack) to use as a platform. Thanks in advance for any advice!
