Got a clone direct from Hong Kong and it will only fly a few inches from the floor and spins left - can only be turned left with the control. Took it apart and found some interesting stuff:
1. the main motors are reversed - the back motor has red/blue leads and the front motor has black/white leads.
2. the motors black and blue wires go to the common motor terminal next to the + battery terminal and the white goes to the m2 terminal, the red to the m1 (R3 board) - the reversed wires explains why the heli flys at all

Several questions:
1. what is the difference between the A motor and B motor?
2. the motors will run in either direction - does the motor location matter?

Note: Got another real SYMA S107G and if flys great.
