I just got a Blade CX2 today for Christmas, and I flew it around a bit just now. Mostly just attempting to trim, and practicing hovering. I haven't been able to keep it in the air for more than a minute, as I'm scared it'll drift into a wall or table. I'm thinking about getting the training kit, and possibly a heatsink for the motors. I felt them with my finger, they seemed pretty warm. Also, when I flew it a bit higher than my head, it started going in slow circles, with the nose pointed in the same direction the whole time. Any tips on how to correct this, and also on how to fly it better?
