An AR Drone is essentially a "toy class" quadcopter. It's understandable that it would quickly become boring. But as I'm sure you're aware, there is a lot more that can be done with more hobby-grade quadcopters with rate mode (no auto-leveling). And, like large RC helis, there is the whole other world of the electronics and mechanics that go into building, maintaining, and tuning the aircraft. That, for me, is perhaps even more of the fun than actually flying my multirotors.
