Great fascination is achieved by active working details on scale models, remember e.g. rotary lights and navigation lights.
A working winch adds a special attraction on a model helicopter particularly if it is pivoting and fully functional!
Especially on a Alouette III you hardly need fantasy, to see instead of the model the full-size helicopter in your mind's eye.
We leave it to your discretion to mount this working winch on any other helicopter.
