I gave in and bought a cheap quadcopter based on "which one has the most hits on eBay" on the theory that that way I could get parts easily. Cost $50 in the local RC shop post-xmas sale which is slightly better than eBay , it's tiny and flight time is only ~5 minutes. Which I initially thought would suck, but it turns out to match my attention span fairly nicely.
And for $50 I didn't expect much, "6 axis gyro stabilised" or not. So no great disappointment there. It's controllable, 5-6 flights and I'm starting to get the hang of it. I can sometimes even take off, hover, and land, without losing control. Sometimes. And indoor only, with the fan off.
But the 90 minute charge time is starting to bother me, so I think when I buy a replacement surround for it I'll get another battery or two.
Link is to the manufacturers blurb on a shop site because I couldn't find their site, not a suggestion.
