Not necessarily handling problems. No electric indoor single rotor heli is anywhere near as stable as the XRB SR Lama. But the Lama is limited in it's capabilities. It has NO fast forward flight. It cannot handle ANY wind outdoors. More typical heli models like the Piccolo, Hummingbird, Blade and others are much less stable than the Lama. They require you to fly them actively. The are twitchy, and have a very steep learning curve. And OH so rewarding when you do conquer the hover.
