We went out to Albuquerque's Maloof Air Park this weekend to watch the rc gas modelers fly. Amazing planes and skill demonstrations. I picked up this tiny electric-powered helicopter for thirty bucks.
Unfortunately, the little chopper may not ever get off the ground. It doesn't appear to have enough power getting to the rotors. The problem may just be a loose connector somewhere, but it is challenging to diagnose the issues at this microscopic level. There is a complete set of spare parts including three motors, so I haven't given up on getting airborne yet.
