I recently was out flying when I lost control of the Blade 120SR. When I picked it off the ground the rotor was spinning, tail stopped. Moving either stick caused no change. I changed out the battery with the same results. A friend said that the tail motor was burned out and it was common. I changed out the tail motor with the same results. It is as if the copter is not received any commands. All information is really appreciated since I am new to this sport - but love it !!
