Having done a lot of research on micro rc helicopters, I chose the E-Flite Blade CX2 RTF. Reviews claimed it was easy and fun to fly, both inside and outdoors. I carefully read the manual, viewed the instructional video that came with the machine, made all the suggested pre-flight checks and readied myself for a day of fun. Unfortunately, as the heli was just approaching lift-off, it began spinning madly and fell over. Dismayed, but not daunted, I reset and rechecked everything, thinking I'd overlooked something simple. Tried again and again with the same result. Gave up and requested a return from Amazon. Not sure what tack to take at this point.
