All helicopters in this section are only for RC helicopter enthousiast that already have some flying experience. These models are a little more complex in setup and maintenance, also the very small models require more flying experience than the models in the BEGINNER section. Note that only the collective pitch helicopters can be flown outside. The tiny micro helicopters (fixed pitch and co-axial) are only for indoor use.
