Thought I would toss this up right quick as I am not sure whats going on. Just got my FC40 on tuesday. Love it, have about 10 flights in so far, no crashes (bought a cheap chinese parrot knock off to practice with before purchasing this) so flying that made this thing a breeze. Start up for me is as follows, connect camera, turn on remote, hook up battery, watch the pretty lights flash green and red until I have HL, compass setup (only two flights have been in same area), start the motors and let them run for about 5 seconds then up.. Here is where the problem is, when I go about 4 ft off the ground, it drifts. I've let it go to make sure its not going to try to go back, and it will keep going in one direction until I correct it. I've taken it to about 10 ft and it will still do the same.. any ideas to what might cause this? There is no wind to cause it to do this and I do have both switches in the top position.
