DJI already does self stabilization in all modes to an extent. They make it so any idiot can fly one. Living proof here. However if you really want to get proficient and fly like a pro, dump the expos and spend time perfecting your skills without them. I think if you go to an AMA field and see some of the best pilots they don’t us expo and moist instructors try not to teach with it. all this being said it it is just for recreation and not something you want to perfect or take to the next level, go with expos. Now on to the question, do pros use just the thumb on the sticks or the pinch method LOL. Another can of worms. No matter which mode you use, enjoy!
