Top row of propellers don’t spin
The helicopter fell from about 8 feet, now only the bottom propellers spin.
Please give any ideas what happened
The Syma S107 is a mini RC helicopter that uses gyro technology for stabilization. This helicopter is electrically powered and designed for indoor flight.
The shaft could've broken, making it spin freely.
If turning the upper blade still turns the ring-gear in the middle of the copter you need to check if the gearteeth is meshing with its corresponding motor
my 2 cents, hope it helps :)
