*** Squiffy,counter rotating means that the two seperate sets of blades are geared together,one to turn in a clockwise direction and the other in an anti-clockwise direction,this totally eliminates and also balances out any torque effect of the spinning rotors with no need for a tail rotor.
Steve Bishop was killed when the main rotors cut the tail off from his Robinson R.22 helicopter,this is called rotor slap induced by a negative force on the control column,this phenomenon can be noticed sometimes on model helicopters after an heavy landing when the blades strike the boom,you notice a ding in the boom,after this everything has to be checked out as something is bound to be bent.Things are more serious on full sized machines.
The thing with helicopters is that they are inherantly unstable and need to be flown all of the time.

I believe, correct me if im wrong but wasnt steve hislops death blamed on rear rotor failure? it failed so the main rotors tilted backwards chopping off the tail or something like that?
When you say counter-rotating do you mean one rotor spins as the other stops? like in a car engine? |
