The DJI Mavic Pro is a marvel of technology that records breathtaking 4K video that is worth buying a 4K screen to view. But it should not really be seen as a model aircraft. Rather it is a flying camera that can do some amazing things.
Recognising my interest in model heli's, my wife bought me this electric T-Rex model in 2016. I have to say that the model is way more capable than I am and that I've not made much progress in setting it up and learning to flying it properly - I kind of got distracted by drones along the way.
