WLToys V911 straight from China for $48 to my door (Heliport). 4-channel (it'll go sideways) real radio, single blade with a squash plate control, removable battery and very stable. You can fly it indoors or outside. I've crashed mine hundreds of times with no problems. The landing at the end of the video (taken with an $8 spy camera) is typical for me.
