Hello
parts of what you are asking is feasible with failsafe - the most important part is auto-motor-off after landing which is not covered. and this one is scary and dangerous at the same time
the more important question is the legal aspect: is it legally approved in your country to let a helicopter fly completely autonomously (and covered by insurance)? and this is what you are asking for: autonomous flying. you have to have 100% control over the model at any time and in case of loss of signal, the engine must stop - this is the only safe way. bad for our models - but the only safe way for "the rest of the world". otherwise there is always the question of legal liability in case of accident / damage during autonomous flight... Spirit manufacturer or pilot? and this is most probably the reason that no fbl manufacturer will support such feature in the near future (just compare to automotive
). different story with normal, smaller drones - not even close that dangerous.
in my case i.e.: failsafe is >> level the heli, everything to neutral and motor off.
