pain to set up... hard on batteries... very short flight time...hard on motors...
more trouble than it is worth
I agree it is pain to set up and it takes a lot of practice too. But when you finally preform a nice inverted hover or a completely new manoeuvre, then all the trouble and effort is repaid. 4D is the most Challenging and the most adrenalin way of flying. You don't see many new 3D manoeuvres. Most of them is only new combination of old things. But 4D is an "uncharted territory". You can preform a completely new manoeuvre each time you go out flying. That is a great feeling too.
