If your model aircraft was below our eye level and you turned it anti clockwise, the nose would indeed need to go to the left …
… however, if your model ac was above our eye level, lets say in a 20ft hover and you were to turn it anti clockwise, you'd have to move the nose to the right.
Well of course I can see that. But if a helicopter is rotating anticlockwise and climbs from a starting point below you to a point higher, it's still rotating the same way, it's just your view point that is changing. So hence my point about a universal standard.
It is generally recognised that a helicopter yawing left is rotating in an anticlockwise direction.
