Our first indoor event of the season was Nov. 13. I always make sure I have an Ember for these events. 95% of my Ember flying is outdoors, in calm conditions, late afternoon or early evening. The lights really help when flying in dusk to dark conditions. If you really like the Ember, you will probably find the Vapor a tad boring. However, the Night Vapor will certainly provide for some early evening, even night time flying. I personally feel the Ember flys more like a plane. I just can't get into the high Alpha flight configuration that is popular with Vapors when in close quarters. I just picked up a mini Vapor. Haven't flown it indoors yet, just outdoors. Not all that excited with it. For slower (versus REALLY slow) flying and great stability, my three Embers do just fine for me. Now for speed, my UMX Mig 15 really fills the bill!
