Translating tendency

From RC Helicopter Wiki

Translating tendency is the tendency for a helicopter to drift to one side in the hover (for model helicopters with typically clockwise main rotor rotation, this would be the tendency to drift left).

Translating tendency is caused by thrust from the tail rotor pushing the helicopter sideways. The pilot can compensate for this by tilting the rotor disk slightly right to counteract this thrust. This is why when the helicopter is in a stable hover, it is always at a slight angle.
