I found that it wasn't so tricky. Just hover so it is about eye level or maybe a foot higher. Reach up underneath and grab with your hand right around where the battery release tabs are. The hardest part is that when you are doing this catch by yourself, you need to hold the rc in the other hand and as soon as you grab the MP, pull down on the left stick to shut down the rotors. As you do it a couple of times, you gain more confidence. Best to turn off VPS to disable the downward sensors. Otherwise the MP will see your hand as an obstacle and start to ascend to avoid the obstacle.
Good luck
