Hi Jane. The Aircraft may lift up if you bring your hand up to meet it as it's descending; that's the landing sensors raising it out of what it initially thinks is an unsuitable spot to land.
If you hold your hand flat and still, and just lower the left stick, it will come down to you. The other tip is to leave your hand at the same height until the motors shut down; if you drop your hand as soon as it touches it, the aircraft may think it hasn;t fully landed.
I've done two videos on hand catching; the method for the
Air 2 is the same as the Mini.
Cheers
Ian
