My Shuang ma 9101 double horse S has stopped flying after just two flights. The battery is fully charged and the LEDs work fine. The rear motor has lost significant power, after checking to see if both motors worked using a nine volt. Later the quadcopter would not even spin on either gear. The transmitter was working and the red LED on the motherboard indicated so. The tail blade was also not working even when the front and rear motors work. (the rear blade has it's own motor) Also any answers to intermittent signals would be great help.
-Thank you, a concrned flyer.
