Froze my Motor

[Cafguy]

Balance a platter on one finger..Place 4 equal weights balanced on the platter NOW once its all balanced remove one of the weights....What happens?....The same thing happens if you lose a motor in flight, just a bit more dramatic and tumbly..

It's even worse than that... In addition to the gravity balance, the torques are balanced between opposing diagonal pairs. Lose one motor and the drone will spin around the yaw axis uncontrollably, as the one remaining motor on that diagonal can not counter the torque from the other two.
