i use both, why not? that is what the modes are for, sometimes i have done what i want or need to do and someone will want to chat and have a smoke etc etc.
Then yes i will hit RTH, why should i not trust these systems, that is what i paid my money for too. if i cant use them i might as well just buy a cheaper drone and be done with it.
i have used RTH many times, like i say sometimes there are other distractions going on which makes RTH perfect even just for having a smoke break before another flight, chatting to people who come up and wanna ask a lot of stuff about the drone (great way to reassure people drones are safe and can do this kind of stuff).
It is normally one of the first things i am asked "can it fly itself"
and i love the gormless look on their faces as they stare into the sky for 5 minutes trying to spot a drone and they only see it when i ask em to move out the way before it lands on their heads.
Tech is built to be used, i don't buy a car and leave it in my garage in case it breaks down, or never use the seat belt just in case it does not work, or use the satnav in case i end up in a river.
If it has a use and a function i will use it.
