Confidence comes with trying out the commands.
I am a strong supporter of manual flying. It teaches the control 'instinct' so important in RC models.
The usual observation is when a new pilot appears - they react to what the model does. This means model is in control.
It takes time and practice for the Pilot to take command and the model to do as told !
Call it what you want ... muscle memory ... the feel .... instinct ... it all comes down to one thing - action that dictates what model is to do.
On fixed wing flying when I teach new pilots ... I get them to fly figure 8 circuits. Why ? Because it has all the elements in that teach that. It has turns both directions, it has upwind and downwind legs, it crosses over in front and needs change of apparent orientation.
On to these Multi Rotors such as the P3 ... DJI have made it too easy for a new pilot to be lulled into a false sense of security. The model takes off .. hovers ... auto-lands ... RTH .... etc. all at the touch of an icon. Get dis-orientated ? Hit RTH and bring her close in ... hit cancel and back in business again.
What would be better is to learn to fly ATTI mode so that any situation you can fly with the sticks with knwledge that RTH is there as well.
People laugh at the 'Toy' Quads from such as WLToys ... but believe me - if you want to learn to fly a quad manually - they are an excellent cheap way to do it. I have a V959 with camera ... cost about $50 ... I flew that baby till I could just about make it do anything I wanted ... the P3S is a walk in the park compared to that 959. But at least I have knowledge from the 959 that helps me if I have any upsets.
I am member of the Latvian group LARPAS ...
Latvian Association of Remotely Piloted Aircraft Systems
There is another member on this forum as well ... but he's a lot "quieter" than me !!
LARPAS is actively involved in forming the Guidelines for Latvian CAA to 'govern' RC flying ... and the single largest item of all which takes up more than 75% of the discussions ... models such as these Phantoms and other Multi Rotor platforms. Why ? Because of the ease to fly - people get stupid and fly them in unsuitable locations or just fly them stupidly. One of the items I raise with LARPAS is the matter of how to get people to actually learn to fly them, instead of just opening box ... charge up and hit auto take-off !!
Sorry if I am getting on a Soapbox here ... but "wichkans" hit a spot with me about how confident / ability to fly.
