Im also a noob and say stick with dji go until you have some experience.Apps like litchi have more capabilities which in our case makes us more prone to devastating crashes..and in case youre someplace with weather like ohios-dont fly in this cold..the "do's n donts" change -youll most likely have battery issues...which inevitably brings us to indoor flying...unless you have a giant auditorium with 20 foot ceilings you can takeoff dead center in...just wait dude...or youll most likely destroy every prop your p4 came with thinking the obstacle avoidance system would save you.
