Hi, I am beginner rc flyer, and I have crashed my plane, and also repaired it, but the motor shaft has bent slightly. It doesn't look bad, and its even hard to notice. When motor is not turning, but when it is, the end of the shaft is moving like half of an millimeter. I dont think its dangerous, but also I don't think its good, so is there reason for changing motor/shaft and can it cause damage to vehicle? My model is Panda Multiplex.
