I think I need to send my S107 back
It doesn't fly more than 6" above ground. It's kinda fun, but still! It's done that since I got it a week or so ago.
After the battery has discharged a bit it will do that. I get about 3 min of vertical flight, then about 7 minutes of 6" off the ground. Are you letting it charge all the way before giving it a try?
